Different battery sizes contribute to the overall effectiveness of your equipment, but it is important to understand why. Generally, the larger the cell is, the more capacity it has for energy storage. So even though a big and small battery are both rated at 1.5V, the big cell stores more energy and provides a longer life.
Different Sizes for Different Jobs
Also known as “triple A”, are the second most popular kind. Triple A are often used for small electronic devices such as TV remote controls, kitchen timers, graphing calculators, and bathroom scales. AAA, like AA, also measure at 1.5V, but generate less energy due to their smaller size.
Also known as “double A”, AA are by far the most popular battery size. Used in a multitude of applications, can be easily purchased almost anywhere. Used in everything from thermometers and staffing pagers to cordless phones. AA batteries measure at 1.5V, and work well for devices that require a somewhat high current draw, but are not in constant use.
These heavy-duty batteries are mainly used for toys, flashlights, and portable radios. Many automatic hand sanitizer dispensers require the use of these 1.5V batteries. Perfect for heavy-duty applications where cells require frequent use.
Used for devices that require an extended period of power time, will work best in large flashlights, and hands-free soap or paper towel dispensers. Powering most automatic paper towel dispensers, D batteries are essential. These large, batteries provide hours of use and power a variety of commercial, heavy-use devices.
Generally known for its rectangular shape, the 9-Volt battery is used in devices that require high voltage and lots of power. 9V work extremely well for devices like infrared thermometers, temperature alarms, and electronic portion scales. These products may all encounter extreme temperatures from food, walk-in coolers, or other kitchen equipment.
Smaller in size, is commonly used in small devices such as garage door openers, specialized medical devices, watches, or remotes. Delivering 12 volts of power, it is used in applications that require infrequent but powerful bursts of energy. They are now used primarily for garage door openers, wireless doorbells, and keyless entry devices.
This small round battery offers a lot of power in a compact size, making it unique compared to most other batteries. At 3 volts, the CR2032 battery is commonly used in watches, calculators, toys, and different medical devices. Providing long-lasting, reliable power and have a very high weight-to-power ratio.
