Battery chargers are devices for charging rechargeable batteries.

Rechargeable batteries or secondary batteries contain active materials that can be regenerated by charging.

Electrical contacts and contact materials are soft, high-conductivity, oxidation- resistant materials that are used in circuit breakers, relays, switches, and electrical discharge machining (EDM) applications.

Industrial batteries translate chemical energy into electricity.

Battery packs are constructed from two or more individual cells or batteries.

Battery charger ICs are integrated circuits (IC) that are used to charge batteries.

Radios are communication systems that send and/or receive electromagnetic waves.
