Batteries are devices that store and discharge electrical energy for numerous applications. They range in size from tiny ones that power watches to large ones that run trucks and automobiles. The following questions and answers can help you understand more about these useful items.

An Introduction to Batteries

What’s the difference between volts and watts?

While wattage and voltage are often used interchangeably, they have different meanings. A battery’s voltage refers to the energy used by electrons to move from one point to another, representing its electrical potential. Wattage refers to the rate at which energy is transferred. A battery with insufficient voltage will not power an item effectively, whereas one with insufficient wattage won’t distribute power quickly enough.

How long do they last?

A battery's useful life depends on several factors, including how it’s used, what it’s used for, how it’s maintained, and the temperature in which it’s kept. For example, auto manufacturers typically aim for a lifespan of up to 15 years with proper care. A standard AAA battery may provide power for about six months, whereas a lithium AAA battery could last up to three years. Batteries of all types typically last for several hundred cycles of discharging and recharging.

Can they wear out when not in use?

A battery contains chemicals that act as conductors for electrical energy. When power is needed, a chemical reaction occurs that discharges it as needed. When a battery isn’t in use, some of these internal components may still react with one another, slowly eroding the total amount of stored energy. This is called self-discharge. The rate at which electricity is lost will depend on the type of battery, ranging from 1% to 10% each month.

What should I do with old ones?

Batteries contain large amounts of chemicals, such as cadmium, lead, zinc, mercury, and lithium, to store and conduct electricity. However, if left to decompose in landfills or other unprotected sites, these chemicals can leak out of the casing and harm wildlife and local water sources. To prevent this hazard, you can take old power cells to the retailer who sold them, an automotive recycling center, or an approved waste management site.
