“Small alkaline button cell batteries usually have a capacity of 150 mAh and weigh about 2.4 grams. They are commonly used in watches, calculators, and remote controls. For devices requiring more power, zinc-air batteries provide a higher capacity of up to 620 mAh, making them suitable for longer-lasting usage.”
Several battery equivalents exist for small alkaline button cells. Popular models include the LR44, AG13, and 357, which can often replace one another due to similar voltage and capacity characteristics. Consumers should always check compatibility to avoid device malfunctions.
The dimensions of small alkaline button cell batteries vary based on type. For example, the LR44 measures 11.6 mm in diameter and 5.4 mm in height. Other sizes include the CR2032, measuring 20 mm in diameter and 3.2 mm in height, often used in watches and fitness trackers.
Next, we will explore the environmental impact of these batteries. Understanding battery disposal and recycling processes is vital for minimizing waste and protecting our ecosystem.
