Battery chargers are devices for charging rechargeable batteries

Industrial batteries translate chemical energy into electricity

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

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

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