LR44 Battery Equivalent, Voltage, Size, Uses Life (FAQs)
LR44 battery is a very popular and common type of button cell. It falls under the category of primary batteries which are non-rechargeable. The key highlight of these batteries is their small and compact size. Hence most small-sized devices such as watches, toys, and calculators use LR44 batteries. Let’s discuss all the important details about LR44 batteries in this article.
The name LR44 follows the battery nomenclature defined by the International Electrotechnical Commission (IEC) in its 60086-3 standard. As per this protocol, the first letter denotes the battery type, the second letter denotes the shape, and the last two digits denote the dimensions.
L in LR44 stands for alkaline chemistry and R stands for round shape. The actual representation of LR44 batteries is LR1154 where 11 denotes the battery diameter and 54 denotes the battery height.
Apart from this 60086 standard, the battery manufacturers assign their own part numbers to the existing label such as LR44G, LR44GD, LR44H, etc.
What is an LR44 Battery?
An LR44 battery is a small, cylindrical cell that is used in a variety of electronic devices. These batteries are also known as button-cell batteries due to their small size and round shape. Common applications for LR44 batteries include watches, calculators, and laser pointers. While LR44 batteries are not rechargeable, they can be replaced when they reach the end of their lifespan. For most applications, an LR44 battery will provide between 50 and 200 hours of power.
Since LR44 is a flat-shaped battery, people find it difficult to locate the positive and negative terminals. The flat side with markings is the positive terminal and the other side has a small circular protrusion is the negative terminal.
The button batteries are also available in silver oxide chemistry. But the alkaline variant is the most popular. The battery falls under an affordable range and has an excellent price versus quality ratio.
Another advantage of LR44 is that it is free from toxic materials like mercury or cadmium. Thus they are environmentally friendly and easily disposable. They are lightweight batteries and are thus largely chosen for purposes where weight is a serious concern.
LR44 Battery Equivalent/Alternative/Replacement
LR44 batteries are produced by several brands on a large scale due to their heavy demand. But the name assigned by the company may vary. Some of the exact equivalents to the LR44 battery are Duracell 76A, Energizer A76, and AG13 batteries.
Several other batteries are available in the market that can replace the LR44 battery. The batteries that can replace LR44 are L1154, LR1154, and 157 batteries. All these are the equivalents to the LR44 battery that produces 1.5 V itself.
The silver oxide chemical composition can also be used in place of LR44 batteries. They have the same size and dimensions but are not the exact equivalents in terms of capacity and other performance criteria. Examples of silver oxide equivalents of LR44 include battery 303, SR44, SR44SW, and 357.
Note: Whenever we plan to replace a battery with its equivalents, do not just stick to its size. Although it fits the slot, the voltage and power output should match the device’s requirements. Otherwise, it causes severe damages due to over/under discharge.
What is an LR44 Battery used for?
Are LR44 batteries the same as 357 batteries?
Both LR44 batteries and 357 batteries are button cell batteries of the same size. But the LR44 battery has alkaline chemistry and the 357 battery has silver oxide chemistry. Compared to LR44, 357 batteries show a 30%-100% longer life span. Since 357 batteries are silver-based, it is comparatively more expensive than LR44.
Is LR44 the same as CR2032?
CR2032 is another type of button cell battery but not at all similar to LR44. CR2032 differs in every aspect including dimension, battery chemistry, nominal voltage, etc. LR44 is an alkaline battery, whereas CR2032 is a lithium-ion battery.
Can I replace LR44 with SR44 battery?
Both the batteries are physically the same. The size and shape are the same. The major difference is their chemistry. SR44 is a silver oxide battery and LR44 is an alkaline battery. Thus the nominal voltage of SR44 is slightly higher than LR44 which is 1.55V. SR version has better features than the LR version except, it is more expensive than LR44. Thus these batteries are interchangeable.
Is LR44 a lithium battery?
The LR44 battery is usually confused with a lithium battery due to the letter L. But LR44 is not a lithium battery, but an alkaline battery. The nomenclature is based on IEC 60086-3 standard in which the first letter stands for the battery chemistry. Accordingly, L stands for alkaline chemistry.
Are there any safety concerns for the LR44 battery?
Alkaline batteries are very dangerous for children. Since they are largely used in toys, the LR44 batteries should be taken good care of to keep them out of the reach of children. Since it is a small-sized battery, the children may swallow them which can cause serious health issues.
Also, these batteries may leak out or explode when short-circuited, force discharged, overcharged, overheated, or disposed of in the fire.

R44 Alkaline, Silver Oxide, Zinc Air and Mercury Oxide Batteries Comparison
LR44 Battery
This primary alkaline button cell battery is a typical R44 battery.
- It is 11.6 mm in diameter, 5.4 mm in height and weighs around 1.7-1.8 grams.
- The capacity of LR44 batteries depends on discharging conditions. When discharged over ~8k? resistor, from 1.5V down to 0.9V at room temperature of 20°C, their typical capacity is around 100-120 mAh.
- It takes about 675 – 700 hours (almost a month) to fully discharge LR44 at this rate.
Note that voltage in alkaline batteries decreases with battery life.
The self-discharge rate of LR44 battery is at most 10% per year – one of the reasons why they are also used as motherboard batteries, although the CR2032 battery is more often used as such.
The Silver Oxide R44 Battery
- Since voltage is slightly higher, sensitive equipment designed for use of silver oxide batteries can have issues when ordinary LR44 batteries are used.
- Check the manuals if your device accepts LR44 instead of SR44 and vice versa.
Silver oxide batteries maintain voltage with battery life much better than alkaline batteries.
Zinc Air R44 Battery
It costs more than alkaline LR44.
- It has somewhat lower voltage, but much higher capacity.
- The PR44 (zinc-air R44) are mostly used in hearing aid devices and they use moist electrolyte and air for operation.
- If the electrolyte dries out before they are fully discharged, they stop functioning.
Mercury Oxide Batteries
They contain mercury (hence the name) and are withdrawn from the market.
They had slightly lower voltage than alkaline batteries, but almost double the capacity – similar to the silver oxide batteries.
LR44 Battery Equivalents and Replacements
Manufacturers often have their own designations for LR44 batteries, for example: LR44, LR44G, LR44GD, LR44H, LR1154, L1154, L1154C, L1154F, L1154G, L1154H, 6135011748057, 1166A, AG13, A613, AG14, AG-14, G13A, G13-A, 157, 303, 357, A76, AG76, GDA76, GP76A, GPA7, GPA75, GPA76, GPS76A, 1128MP, 208-904, A-76, A76, CA18, CA19, CR44, D76A, KA, KA76, MS76H, PX76A, PX675A, RPX675, RW82, SB-F9, V13GA, etc.

Vacuum Cleaner Motherboard Batteries
Be aware that each vacuum cleaner has its own specific motherboard with certain needs and details that you should look over before replacing. For example, a Replacement Battery Protection Circuit PCB Board for Dyson V6 Vacuum Cleaner looks and acts drastically different compared to a replacement battery for a Shark Navigator vacuum cleaner.
In short, be really careful when replacing a motherboard battery on your own. If you don’t feel confident enough to do it yourself, leave it to a technician or repairman. It’s better to shell out extra cash to a pro rather than breaking something for good or even risking starting a fire over a short circuit.
Handling and storage
Proper handling and storage of AG13 batteries is essential to ensure their longevity and safety. Here are some important guidelines to follow:
Keep AG13 batteries in their original packaging or in a dedicated battery case. This helps protect them from exposure to moisture, dust, and other contaminants.
