FAQ

Common battery types include alkaline, lithium, rechargeable, coin-cell, and specialty batteries. Each type is designed for different device categories and operating needs.

Rechargeable batteries are designed for repeated use with a compatible charger, while single-use batteries are intended to be replaced after their stored energy is depleted.

Coin-cell batteries are commonly used in watches, calculators, remotes, key fobs, small electronics, and select computer accessories.

The plus symbol identifies the positive terminal, and the minus symbol identifies the negative terminal. These markings help match the battery terminals with the corresponding symbols in a device.

Battery labels may include the chemistry, voltage, model designation, terminal markings, and whether the battery is rechargeable or intended for single use.
