13 Facts About Rechargeable battery

Rechargeable battery, storage battery, or secondary cell, is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.

Rechargeable battery batteries are produced in many different shapes and sizes, ranging from button cells to megawatt systems connected to stabilize an electrical distribution network.

Some rechargeable battery types are available in the same sizes and voltages as disposable types, and can be used interchangeably with them.

Energy used to charge rechargeable batteries usually comes from a battery charger using AC mains electricity, although some are equipped to use a vehicle's 12-volt DC power outlet.

Many Rechargeable battery-operated devices have a low-voltage cutoff that prevents deep discharges from occurring that might cause cell reversal.
