Additional Information On Standard Alkaline Batteries
Alkaline batteries were invented in 1949 by Lewis Urry, a chemical engineer at the Eveready Battery Company, and have been with us since the 1950s. They are the most widely recognized among primary batteries and served as the next step in off-the-shelf consumer batteries, gradually replacing the cheaper 1.5-volt zinc-carbon that powered most consumer devices at its peak. Alkaline batteries deliver more energy at higher loads than their zinc-carbon predecessors and are considerably less susceptible to electrolyte leaks from spent batteries. Leaks are caused by the production of hydrogen gas all primary batteries produce as they discharge. In the absence of adequate venting, pressure builds that ruptures the battery seal creating a corrosive crystalline formation that can spread even into the host device and cause damage.
In common with other primary cells, alkaline batteries have higher specific energy, hold higher capacities, and deliver nearly 40 percent more energy than newer rechargeable technologies such as the lithium-ion batteries. While impressive in published technical specifications, however, manufacturers often do not mention specific power, or power delivery, which is different from specific energy. Primary batteries are inferior to rechargeable batteries when it comes to specific power, particularly for loads that draw high current. Their lack of strength on loading makes alkaline batteries more suitable for light loads of lower drain applications such as remotes, flashlights, and other portable electronics. Where alkaline batteries fail to address the requirement for high capacity devices, lithium-metal batteries offer improved loading.
Alkaline and other primary batteries exhibit low performance under high load conditions due to their high internal resistance, which is how well electrical current flows through a material, as measured in ohms (Ω). As the battery is discharged, its internal resistance continues to increase, which causes a collapse in voltage. Demonstrating the performance of an alkaline battery in low drain devices as opposed to high drain devices, a depleted alkaline from a digital camera will frequently contain enough energy to power a wall clock for as long as two years.
The most widely recognized among primary batteries is the alkaline, which offers great benefits:
The excellent safety record of alkaline batteries allows for unregulated transport on aircraft. Unfortunately, alkaline cells are limited to light loads of low drain devices such as remotes, flashlights, and some portable electronics. Where alkaline fails to address the requirement for high capacity devices, lithium-metal batteries offer improved loading; however, because they are considered Class 9 hazardous material, the transport and shipping of lithium batteries are subject to stringent regulatory guidelines.

The most common cell formats for primary batteries are AA, or penlight batteries, which were made available for the public in 1915; and AAA which appeared 39 years later to address the needs of camera manufacturers and the rise of smaller devices. Other size formats include the larger C, D, and 9-volt batteries. The 1990s saw the introduction of AAAA (pronounced quadruple A) batteries, originally designed to power laser pointers and other micro-format devices. The AAAA battery owes its origin to the 9-volt battery, which consists of six AAAA cells, each with a rated voltage of 1.5V. Other common formats include various disc-shaped, button cells such as the popular LR44 battery.
The alkaline AAA battery has only about half the capacity of an AA, despite their similar selling prices. To illustrate, a bicycle light powered by an AAA battery will provide half the runtime of the equivalent light outfitted with an AA battery for insignificantly little more. Prevailing consumer trends prioritizing downsizing over energy cost contributed to the disparity between their pricing in relation to their capacities. In their drive to cut their costs, cities will often buy alkaline batteries in bulk and consolidate their purchase orders. Where coin batteries are needed, such as the LR41 or the LR43 battery, others resort to switching to bulk lithium battery purchase orders.
Battery Cell Chemistry
There are four major categories into which cell batteries are grouped:
Alkaline Batteries
Alkaline batteries match other battery types in terms of size. However, they provide less stable voltage and less capacity than their lithium and silver oxide counterparts.
Silver-Oxide Batteries
Silver-oxide batteries are known for their stable discharge. They’re often used in medical instruments and precision devices.
Mercury-Oxide Batteries
Mercury-oxide batteries have stable voltage but are no longer used because of their toxic nature. Incorrect disposal of the battery pollutes the environment.
For example, the United States, through its Mercury Act of 1996, prohibited the use of mercury in favour of mercury-free alkaline batteries.
Zinc-Air Batteries
Zinc-air batteries have the highest capacity compared to others. In addition to the ingredients packed in the cell, these batteries use oxygen from the air as a depolarizer.
They’re termed next-generation batteries, given their potential to hold more energy, their safety mechanisms, and potentially reduced cost per unit.
Battery Chemistry Comparison Chart
IEC 60086-3 is an international standard that defines battery cells using an alphanumeric code format.
The IEC 60086-3-5:2021 particularly provides the requirements, dimensions, designation and methods used to test batteries used for watches.
Package Size
When inspecting a button battery, you may notice a 2-digit code. This represents a typical case size.
A code of 3 or 4 digits speaks for the cell’s height and diameter. In this case, the first 2 digits usually represent the exterior diameter in full millimeters (rounded down). This standard specifies exact diameters with no ambiguity. For example, a cell designated as 9 indicates a diameter of 9.5mm and nothing else.
- SR516 indicates silver, with 5.8 in diameter and 1.6 mm in height.
- CR2025 indicates lithium, with 20mm diameter, 2.5mm height, and 170 mAH.
- LR1154/SR1154 indicates alkaline/silver with a diameter of 11.6 and a height of 5.4. The alternative two-digit code for this is LR44/SR44.
Overview of 357
357 is an alkaline battery with a voltage of 1.5V, commonly known as A76. It is cylindrical in shape with a diameter of 11.6mm and a height of 5.4mm and weighs 3 grams on average.
The battery is usually used in high drain devices such as digital cameras and toys that require a lot of power.
It was developed by the Duracell company in 1989 and has become one of the most popular batteries on the market today.
