Yes, a car battery is a
secondary battery, which means it is
rechargeable.
Secondary batteries can be recharged and used multiple times, unlike primary batteries that are single-use. A car battery, usually a lead-acid type, stores electrical energy and provides power to start the engine and run electrical systems when the engine isnβt running. When the engine is running, the alternator recharges the battery to keep it ready for the next start-up.
So, in simple terms: A car battery can be charged and reused, making it a secondary (rechargeable) battery.
