Can I carry this in my luggage? Batteries
The main types of batteries are described under the headings below, to help you decide whether you can carry your batteries with you when you travel by air. Generally, if you have lithium batteries, battery powered electronic or other small consumer items, the batteries and items are safe to take with you. There are a few things to consider however, and while there are some variations depending on airlines or jurisdictions most follow a generally common-sense approach. All airlines apply the ‘for personal use’ policy.
In addition IATA held a workshop in Canada at the end of September 2015 to discuss improvements in the carriage of lithium batteries which will be attended by representatives from airlines, battery manufacturers and shippers. This is likely to result in some minor adjustments, though probably more aimed at shippers rather than passengers.
Economy Traveller continues to monitoring the latest restrictions on the carrying of electronic devices (including cameras) larger than a average sized mobile phone.
UPDATES: lithium batteries, battery powered devices
We, the travelling public really need to know what we can and can’t carry, so….
This includes both rechargeable and non-rechargeable lithium batteries, including
- cell phone batteries,
- laptop batteries,
- external batteries,
- portable rechargers (or power banks)
- hand tool batteries as described below
- It also includes the batteries used in your cameras and the little round ones in your camera remote.
These are all fine and you can take them with you. There isn’t generally a limit on the number you can carry, but they must be stored correctly. The and – terminals must not be allowed to connect, and you should put them in your hand carry baggage.
As the airport bag scanner is usually your first stop at the airport, make sure that any batteries are already removed so you don’t have to remove them at that point.
Check the rating on the battery as well.
Rechargeable lithium ion batteries, such as the ones shown here are limited to a rating of 100 watt hours (Wh) per battery. This should be printed on them.
UPDATE: Qantas has updated their advisory on this, stating that:
Lithium Ion battery (rechargeable) – exceeding 100Wh and up to 160Wh. Lithium ion batteries over 160Wh are forbidden as passenger baggage and must be sent as freight. Lithium Ion batteries must be declared during check-in. Only two spares per passenger.
Non- rechargeable lithium metal batteries are limited to 2 grams of lithium per battery.
If you’re carrying spares for either, ensure they are easy to remove, in case your hand carry bag is overweight. Airlines often take overweight bags at the departure gate to be stored in the hold.
Rechargeable Nickel Metal Hydride (NiMH) batteries such as the ones shown. These include flash batteries, or if you just happen to be taking a robot vacuum cleaner with you, we’re talking about those. They need to be hand carried as well. If you are taking your robot cleaner (stop laughing!), remove the battery and pack the body in your checked baggage. Just take the battery with you in your hand luggage.
This also applies to Nickel Cadmium (NiCad) batteries. Both types must be 100Wh or less and properly packed to ensure that the terminals can’t touch. (original packing / tape the terminals or pack in individual containers)
These are your everyday AA, AAA, C, D or the rectangular 9V batteries. These are the ones you put in everything from clocks to children’s toys. They are environmentally unfriendly ones you use and throw away.
- Make sure they are not more than 12volts.
- Make sure they can’t make connections between and
- Either keep them in the device, or if spares, in the original packaging.
Other types of batteries
- batteries for a mobility device,
- news camera lighting batteries,
- childrens’ toy vehicles or
- an uninterrupted power supply (UPS) for computer back-up.
These use Sealed Lead Acid Batteries / Non spillable wet batteries which contain either a gel or Absorbed Glass Matt (AGM). You may take these on board with you, but this type of product is usually heavy. They may be packed as checked baggage, but only when installed in the device. Spares must be carried in hand carry bags.
A number of airlines do have specific guidelines for specific items. However, they don’t vary a lot and batteries are usually added into a list of ‘dangerous goods’. You can usually find this information in the Planning/Before you fly tabs on the airline website.
Virgin Australia has probably the best specific list and Qantas includes batteries in their ‘dangerous goods’ list. Jetstar lists ‘dangerous goods’, but follows the same policies as Qantas.
AirAsia is silent on batteries other than ‘devices with spillable batteries’ which forms part of their dangerous goods policy and US Airlines generally follow the FAA Guidelines.
Singapore Airlines has a general ‘dangerous goods’ policy and Air New Zealand even includes a Avalanche rescue backpack in their list.
For further information IATA have material on Dangerous Goods Regulations (DGR). If you are unsure or need more information on quantities or type, please contact the airline directly before you fly.
Can I Take Lithium Camera Batteries on a Plane
If you’ve asked yourself, “can I take lithium batteries on a plane”, you need to know that there are international rules on flying with photo/video equipment, however, at times there may be further restrictions by FAA, TSA security, the individual airline, and other international jurisdictions. Lithium batteries can be taken on planes but with some restrictions. Depending on the quantity, rating, whether they are installed in a device or spares, and whether they are protected from damage or short circuit, will determine whether they can be taken on as carry-on or checked-in baggage. Under IATA rules, digital cameras are classified as Portable Electronic Devices (PED). If you are taking a laptop, perhaps to view and edit your images, the laptop would also be considered a PED, as would your mobile phone, strobes, etc. Although this article provides good information on traveling with batteries for cameras and associated devices, regulations can change at short notice. If traveling with several or larger capacity lithium batteries, or batteries that require the airline’s approval, contact the airline for clarification.
The five types of photo/video batteries you may need to take on a plane
Lithium batteries are the ones that you need to pay the most attention to. However, because makers of batteries and power banks for photo and video use are aware of TSA and international travel restrictions, their power devices are generally designed to abide by the rules.
Lithium-ion batteries can be dangerous if the terminals are shorted, the batteries are damaged, or the device they are installed in can unintentionally be activated.
If you also travel with dry alkaline or dry rechargeable batteries, there are no restrictions on these batteries. Any number can be carried for personal (including business use). They can be installed in devices or carried as spares in both carry-on and checked-in baggage. However, you must ensure they are protected from damage and short circuit.

Can you have lithium batteries in checked-in baggage
Spare or loose Lithium batteries cannot be included in checked-in baggage. Only lithium batteries that are installed in a portable electronic device, such as a camera, Speedlite, or strobe light, can be checked in.
Can you have lithium batteries in carry-on baggage
Lithium batteries, whether installed in a portable electronic device (PED) or spares, can be included in carry-on baggage.
According to IATA, each person is limited to 15 PEDs and 20 spare batteries of any type. However, the FAA’s illustrated guide on batteries for airline passengers and batteries states that “the main limit is that the batteries and devices must be for personal use (includes professional use). There is a two-spare battery limit on large lithium-ion batteries”.
You must ensure that spare batteries are protected from damage and short circuit. Any equipment containing lithium-ion batteries must be protected from accidental activation and heat generation.
Can Lithium batteries be taken on planes if installed in cameras or lights
A lithium battery installed in a camera or light can be taken on a plane, so long as it is 100Wh or less. When installed in a camera or light, the battery does not count toward your battery limit and can be placed in checked-in or carry-on baggage.
So, you can travel with several cameras and lights with installed lithium batteries. But those batteries must be less or equal to the 100Wh limit and the device must be completely turned off.
Installed batteries are not considered loose or spare, but they must not be able to become detached from the camera. If detached from the camera the batteries will be considered as spares or loose batteries, which are not allowed in checked-in baggage.
Can You Take Spare Camera Batteries on Planes
Spare dry cell batteries can be taken onboard planes in checked-in or carry-on baggage without any restrictions other than they are for your own use, and they are protected from damage and short circuit.
Spare lithium batteries, whether for your camera or another portable electronic device, can only be taken on a plane as carry-on baggage, they are NOT allowed in a suitcase or equipment case that is checked-in either at the gate or planeside.
Please read the sections below on how to pack camera batteries and prevent short circuit.
Can Larger Lithium Batteries Go on Planes
Larger Lithium-Ion Batteries in the 101-160Wh power capacity range can go on planes, with airline approval. According to FAA and IATA regulations, a maximum of two spare larger lithium batteries can be taken on board per passenger. These batteries must
Airline approval is required.
How to pack your camera batteries for a plane flight
If the lithium battery is installed in the device, such as a camera, light, or laptop, ensure the device is completely switched off. It should not be left in standby, hibernation, or sleep mode.
Ensure the device is packed properly to prevent accidental damage to the device and installed batteries. This will also help prevent the batteries from becoming detached from the device, so avoiding the chance of short circuit or damage.
Place devices in a suitable case or bags for protection.
To help avoid problems and delays use appropriate packaging for spare batteries and ideally apply labels that correctly state what the batteries are inside. If you are transparent in your intentions, you are less likely to arouse the unnecessary attention of those responsible for your and others security.
If you have the original battery packaging place the battery in it. Not only will the battery be safe but it will also provide clarity as to what is being carried.
Loose spare batteries can be put into a ziplock bag or box.
Battery organizers or storage boxes/cases are an ideal solution. Some are made from transparent plastic and snap shut, while others are padded and close with a zipper. You can even get travel storage cases that have recesses for memory cards and popular camera batteries.

Protecting your batteries from short circuit
It is important that batteries do not accidentally short-circuit since this could cause them to catch fire.
The battery terminals should be protected from short circuit, meaning that the terminals should not touch other metals.
Simple ways of ensuring your batteries do not short circuit include keeping the batteries in their retail packaging, covering the battery terminals with electrical insulating tape, and placing the batteries in a battery case, plastic bag, or protective pouch.
Some batteries, such as Canon’s LP-E6 series, come with an orange/yellow protective plate that covers the back of the battery and terminals. If you’ve lost the original, you can buy replacement covers quite cheaply.
To protect the electrical contacts on batteries I prefer using electrical insulation tape. Unlike parcel tape and Scotch tape, electrical tape does not leave a sticky residue. It’s also available in a few different colors, other than black. Yellow and green is my favorite since the color makes it obvious that the battery contacts have been taped over.
Can I take damaged or recalled lithium batteries on a Plane
Damaged or recalled lithium batteries must not be taken on planes, whether as carry-on or checked-in baggage. They are a fire risk and therefore could endanger the safety of the aircraft, passengers, and crew.
Can power banks be taken on planes
Power banks can be used to recharge various devices used by photographers or videographers. They can even be used directly, using a dummy battery, to power a camera. Therefore, it’s worthwhile knowing whether you can travel on a plane with a power bank.
Power banks are considered as spare batteries, they can only be taken on planes in carry-on baggage and are not permitted in checked baggage. Power banks up to 100Wh do not require airline approval, however, power banks that have a power rating of 101-160Wh do require airline approval.
Unfortunately, most power banks do not state their power rating in Watt hours but in milliamp hours, so you will have to use a formula to convert between the two.
In the next section, I explain how to do the calculation to convert from milliamp hours to Watt-hours. But as a guide, a 10,000mAh power bank should be airline friendly, being under the 100Wh limit, and therefore can be included in carry-on baggage without airline approval.
A word of warning about calculating the Watt hours of a power bank. It is the 3.7V voltage of the batteries in the power bank that is important and not the 5V output voltage of the power bank. So, use 3.7V as the battery voltage in your calculation.
The maximum power of a power bank that can be in carry-on baggage and does not need airline approval is 100Wh or 27,000mAh.
Higher capacity Power banks are classed as a larger Li-ion battery (101-160Wh), so require airline approval and are limited to a maximum quantity of two.
You can carry on two higher capacity power banks rated up to 43,000mAh but these require airline approval and count toward the number of Larger Lithium-Ion batteries you can travel with.
For example, your carry-on baggage cannot include two high-capacity power banks plus two larger Li-ion batteries for camera gear.
How to calculate the Watt hours (Wh) of a camera battery
Usually, camera batteries have their Watt hours printed on the back, alongside their Amp hour rating. For example, on a genuine Canon LP-E6NH battery the power pack indicates that it is rated at 7.2V, 2130mAh, and 16Wh.
If the Watt hours figure is not printed on the battery you can calculate it by using this formula,
Watt hours (Wh) = Voltage (V) x Amp hours (Ah)
Since most camera batteries show their Amp hour figure in milliamp hours (thousandths of an Amp hour), you should divide the figure by 1000 so the figure is in Amp-hours instead of milliamp hours.
So, if working with milliamp hours, as quoted on most camera batteries, the formula becomes,
Watt hours (Wh) = (Voltage x milliamp hours) / 1000
Doing the math on the Canon LP-E6NH battery, the watt hours is 7.2 x 2.13 = 15.3Wh. So, the value printed on the back of the battery has been rounded up to 16Wh, or the actual battery voltage is likely to be 7.4V.

Understanding How Batteries Work
Batteries power everything from life-saving pacemakers to our lifestyle-facilitating cell phones. They also allow us to transport electrical power wherever we need it, from the South Pole to the Amazon and everywhere in between, providing light, heat, communications, and more.Batteries power everything from life-saving pacemakers to our lifestyle-facilitating cell phones. They also allow us to transport electrical power wherever we need it, from the South Pole to the Amazon and everywhere in between, providing light, heat, communications, and more.
Almost all of us will have relied on batteries at some point, perhaps reaching for a flashlight during a power outage. Our interconnectivity with batteries means we rarely stop to ask, “How do batteries work?” This guide covers everything you need to know about batteries, from their 18th-century beginnings to why you shouldn’t charge a cold car battery.
Introduction to Batteries
Batteries give us a portable electric current or electricity and the ability to store energy. Energy is omnipresent throughout the universe in various forms.
Electricity is the movement of electrons between atoms, where electrons bang into each other to create an electrical flow. Batteries do not store electricity — they hold electrical energy in chemicals contained within the battery. What a battery does is convert its stored chemical energy into electric current.
How Do Batteries Work?
Let’s look at a classic AA battery, commonly used in remote controls, toys, and more. At one end of the battery is a negative end, called an anode At the other end is a positive end, called the cathode. Both the anode and cathode are also known as electrodes or electrical terminals.
The battery’s body separates these negative and positive electrodes. Within the battery’s body are electrolytes, which act as a sort of barrier between the anode and cathode. These three parts form what is called an electrochemical cell — two electrodes (the anode and cathode) — separated by an electrolyte (the battery’s body). A battery consists of several of these cells.
When a battery sits idle, not making an electrical circuit, the electrolytes and electrodes are dormant. As soon as you make a circuit, for example, by putting the battery into a flashlight and turning it on, a chemical reaction begins.
The anode, our negative electrode, reacts with the electrolytes and produces electrons, which build up at the battery’s negative terminal. The anode is usually made from a material that likes to give up electrons, also known as an oxidation or oxidized material.
At the positive terminal, the cathode electrode reacts with electrolytes to create ions — atoms with too few or too many electrons. The cathode is made from a metal oxide that likes to collect both ions and electrons.
As the saying goes, opposites attract. The electrons want to travel from the negative terminal (anode) to the positive terminal (cathode). The electrolytes act as a barrier to the electrons and the electrons cannot travel through the battery’s body. At the same time, charged ions flow through the electrolyte solution that is in contact with both electrodes.
With our flashlight, we make an external circuit when we insert batteries and turn on the flashlight. The blocked flow of electrons looks for the path of least resistance. The electrons want to leave the anode and travel to the cathode.
Our electrons find that the external circuit offers the path of least resistance to move through the external circuit we have created. They flow from the anode through the flashlight’s wires and light bulb to the cathode. They recombine with the ions at the positive terminal to complete the circuit and illuminate the bulb en route. Remember, electricity is the movement of electrons between atoms.
This process is known as reduction-oxidation. or a redox reaction, the scientific term for any reaction involving the exchange of electrons.
A battery’s electrolyte can only perform this chemical reaction a certain number of times before it no longer produces ions and the battery is flat.
What Is Inside a Battery?
We’ve looked at the three main parts of a battery: the negative electrode (anode), the positive electrode (cathode), and the electrolytes that separate these electrodes.
Let’s look at the components of an AA-size alkaline-manganese dioxide battery, also known as alkaline batteries.
Externally, the battery has steel-plated positive and negative electrodes, and the main steel body is covered with a PVC label.
Internally, the battery has a brass rod acting as a central shaft that acts as a current collector. A separator surrounds this brass rod to keep it away from the electrolyte solution. There are two types of electrolytes within the battery — the anode has a gel of powdered zinc and the cathode has manganese dioxide. There are various seals and washers, too.
Batteries with different materials for their electrodes and electrolytes produce different chemical reactions. These affect how the battery works, from its voltage to energy storage capacity. For example, there would be no flow of electrons if we used the same material for the electrodes.
For a more in-depth look, watch this video about the battery-making process.
Different Types of Batteries
There are many types of batteries. The first distinction to make is whether the battery is a primary battery or a secondary battery.There are many types of batteries. The first distinction to make is whether the battery is a primary battery or a secondary battery.
Simply put, a primary battery is not rechargeable, and a secondary battery is rechargeable. Generally speaking, a primary battery has more energy density than a secondary battery, meaning a primary battery can provide power for longer than a secondary battery. Another important difference: We can recharge and recycle secondary batteries but only recycle exhausted primary batteries.
There are several types of batteries within the two classifications of primary and secondary batteries. Let’s look at primary batteries first.
What Are the Three Main Types of Primary Batteries?
We use primary batteries in many important aspects of our lives thanks to their longevity. A pacemaker is a fantastic example of primary battery use — we can’t just keep operating on people whose pacemaker battery needs recharging.
Primary batteries are also known as dry cell batteries. But they are not dry. The term comes from the fact that the battery’s contents cannot be spilled, no matter its position. Different materials set each battery apart, with each material altering the battery’s power and lifespan. There are three main types of primary batteries:
- Zinc carbon : Also known as the Leclanché battery after its French inventor George Leclanché. was one of the first batteries available and remains one of the cheapest to this day. As you likely guessed, its electrodes are made of zinc and carbon. These batteries come in cylindrical and rectangular shapes and tend to have a relatively short lifespan. They work better with low-energy demand appliances such as toys or TV remote controls. In addition, modern zinc carbon batteries may use zinc chloride to increase their potential; these are often called “heavy duty” batteries.
- Alkaline: The alkaline battery rose to prominence around a century ago. It uses different materials than a zinc carbon battery. Rectangular and cylindrical alkaline batteries have a zinc anode and a manganese dioxide cathode, with potassium hydroxide as their electrolyte. There are many practical advantages to alkaline batteries compared to zinc carbon batteries, with longer and more powerful discharges, greater storage life, and better ability to function in colder conditions.
There are more subsets of alkaline batteries, too, whose power depends on its electrodes — the electrolyte remains potassium hydroxide.
Finally, button batteries. such as those used in watches and hearing aids, have a zinc anode and a silver oxide cathode. Button batteries are expensive, renowned for their long life, and offer high discharges.
You can create an alkaline battery with a nearly unlimited shelf life called a zinc air battery by changing the electrodes again. A zinc anode combined with an oxygen cathode makes an alkaline battery used in hearing aids, pagers, watches, and more. Zinc air batteries have the highest energy density of all disposable batteries and come in cylindrical, 9-volt, and coin shapes.
- Lithium: These batteries complete the primary battery section and are among the more expensive batteries. They are commonly used in digital cameras and other small appliances. Lithium batteries. which are usually cylindrical or button types, use an organic electrolyte. Lower volt (1.6V) lithium batteries have a lithium anode and an iron sulfide cathode, while higher volt (2.8-3.2V) lithium batteries swap iron sulfide for manganese dioxide cathodes.
What Are the Types of Secondary, or Rechargeable, Batteries?
There are also three types of secondary, or rechargeable, batteries. Like primary batteries, there are alkaline and lithium types secondary batteries. The third type of rechargeable battery is a lead-acid battery, famous for use as a car battery. Similarly, changing the battery’s raw materials affects its performance and uses. You should always recycle rechargeable batteries because their valuable components can be reused.
These are not just car batteries; they are also used in wheelchairs and emergency power sources. Lead-acid batteries are heavy, cheap to manufacture, and have an extended life. They feature lead anodes, lead dioxide cathodes, and sulfuric acid electrolytes.
There are two types of alkaline rechargeable batteries. Nickel-cadmium batteries, also known as Ni-Cd or NiCAd batteries, were widespread when people started using rechargeable batteries for toys, personal music players, toys, and so on. They performed and recharged well, but the toxic cadmium was challenging to recycle.
The cadmium anode was replaced by a lanthanide or nickel alloy anode to create the nickel-metal hydride battery or NiMH. These are much safer than the Ni-CD batteries, offer excellent power supply, and recharge well. You’ll see cylindrical and rectangular rechargeable NiMH batteries on sale, and they are used in electric cars.
3) Lithium-ion batteries
Lithium-ion batteries have revolutionized our relationship with batteries. Our cell phones, laptops, and electric cars run on these quick-charging batteries. They use carbon anode and lithium cobalt dioxide cathodes, and an organic electrolyte. Lithium-ion batteries are also used at giant battery farms to capture excess renewable power for later use.
What Are the Different Sizes of Batteries?
Batteries are similar to boxes and cupboards when it comes to thinking about storage. The bigger the battery, the more electrolytes it contains, and the more electrical charge it offers. The most common battery sizes in our day-to-day-lives are:
- AA batteries: Known as double-A batteries, these are cylindrical and the most commonly found batteries for millions of gadgets.
- AAA batteries: Also known as triple-A batteries, these are smaller than AA batteries and often used in TV remotes and gadgets that don’t require high power.
- C batteries : These are bigger than AA or AAA batteries for use in higher-demand items like lanterns, flashlights, and games.
- D batteries: These are larger still for heavier-duty products that have a high power drain or need to be powered for a long time before.
All the above batteries offer 1.5 volts of power.
The recognizable, rectangular 9-volt battery offers more power, and coin batteries provide long lifespans in a small, coin-shaped design perfect for small gadgets like watches.
There are many more specialist battery types, such as the CR123A. also known as the 123, for security alarms and other specific uses.
What Does Battery Voltage Mean?
A battery’s voltage determines how much electric potential it will create once connected to a circuit. For example, a car battery’s 12 volts is a higher voltage than a AAA battery’s 1.5 volts. This is because a car needs a fair amount of power to start, while a TV remote control only needs smaller triple AAA batteries to work.
Think back to the negative end (anode) and positive end (cathode) of a battery. The term voltage stems from the difference in electric potential between the anode and cathode — the greater the difference, the higher the battery’s voltage.
The term volt honors Alessandro Volta. an Italian physicist who invented the world’s first electrochemical cell in 1800. Volta used a zinc anode and a copper cathode with salt and water as his electrolytic solution. In 1881, Volta’s name was given to the measurement of the difference in the electric potential between the anode and cathode. Thus, what was once called electromotive force (EMF) became known as volt or voltage.
Batteries also list mAh values or milliampere hours. The mAh shows how much electrical energy a battery holds. The higher the mAh value, the more energy the battery can store, the longer it will last, and the longer it will take to recharge, too.
Are Batteries AC or DC?
Batteries offer DC or direct current power, providing a regular, steady, and controllable flow. National grids transport electricity using alternative current (AC), a current that changes direction rapidly.
Are Batteries Capacitors?
Put simply, no; batteries are not capacitors. Batteries store electrical energy. whereas capacitors store energy too, but in an electric field.
Problems Using Batteries
Batteries are a great way to transport power, but it’s not always smooth running. Primary batteries can run out of juice at inopportune times. Also, you may not have your charger handy to recharge batteries or have the correct battery for your appliance.Batteries are a great way to transport power, but it’s not always smooth running. Primary batteries can run out of juice at inopportune times. Also, you may not have your charger handy to recharge batteries or have the correct battery for your appliance.
Can Batteries Get Wet and Still Work?
Water is not suitable for contact with batteries. Water can rust the battery’s structure, sometimes causing it to self-discharge and run out of power. The battery’s degradation may also cause it to leak and stop working and possibly explode.
If you accidentally wash clothes with a battery in the. your washing machine should be fine because any leak will be significantly diluted during the machine’s wash cycle.
Overall, it’s best not to get batteries wet. If they do get wet then it’s advisable to stop using them.
Can Batteries Freeze?
Everything can freeze if the temperature drops low enough. So the question is more, can you use batteries in freezing weather conditions, and can you recharge them?
Each battery is different, but all of them work less efficiently once temperatures drop below freezing. The best advice is not to charge any battery that is frozen.
A fully charged lead-acid car battery can work at temperatures as low as.58 degrees Fahrenheit. If it’s low on charge, it could freeze at around 30 degrees Fahrenheit. You can charge them when the ambient temperature is between.4 and 122 Fahrenheit. It’s always best to charge a lead-acid battery at room temperature and not when it is cold or frozen — after all, lead-acid batteries can explode. If in doubt, do not charge the battery and call a professional mechanic to help.
Alkaline batteries work between.4 and 149 Fahrenheit and charge between 32 and 113 Fahrenheit.
Lithium-ion batteries will work between.4 and 140 Fahrenheit and charge between 32 and 113 Fahrenheit.
Are Batteries Allowed on Planes?
Most batteries are allowed on planes — almost everyone carries a laptop, tablet, video game, or cell phone onto a plane.
Dry-cell alkaline and NiMH rechargeable batteries can come into the plane with you, either in your device or in your luggage as spares. These batteries can also be checked into your checked baggage, although it’s best practice to carry them with you aboard. You must only have dry-cell lithium batteries in devices or as spares on board.
Spare batteries should have contacts taped over for the flight and kept in protective cases or plastic bags. Don’t keep extra batteries next to any metal objects because this may cause them to short-circuit and overheat.
If you plan to travel with a spare rechargeable lithium-ion battery, contact your airline for advice in advance. Rechargeable li-ion batteries are generally allowed as carry-on but are often subject to strict size limits.
Can Batteries Be Recycled?
Batteries contain several toxic, harmful, and valuable materials, depending on the battery type. Mercury, lead, lithium, and cobalt are some of a battery’s possible materials and should always be disposed of properly.
Batteries and their components are potentially dangerous and damaging to people, land, animals, and flora. Recycling or returning to the point of manufacture is the best option for exhausted batteries.
Do not put any batteries in the regular trash. Always check with your local or state solid waste disposal section for recycling and disposal methods. Some retailers and manufacturers also accept battery returns, particularly important for automotive and lithium-ion batteries.
Check search.earth.911com for recycling centers or use the call2recycle website for information about battery recycling.
The Future of Batteries
Batteries have come a long way from Alessandro Volta’s early invention. However, they still adhere to his discovery that stored chemical energy can be converted into electrical energy. Technological advances mean we know various materials increase the amount of electricity produced, and design has made batteries as versatile as they are helpful.
Lithium-ion batteries offer days of use to cell phone owners and will help power the electric vehicle revolution. Some 145-230 million new electric cars are expected on the world’s roads before 2030, powered by batteries. Utility-scale battery storage farms are set to explode from four-gigawatt capacity in 2019 to 400-gigawatt capacity by 2040, capturing excess renewable energy for later use.
So, how do batteries work? The basic concept is straightforward. A chemical reaction makes electrons leave the battery’s negative end and travel via an electrical circuit to the positive end. This journey by electrons is what gives us portable, reliable electricity in the form of a battery that powers our daily lives.
