Rechargeable batteries are also known as secondary battery. Unlike the primary cells, these batteries can be recharged.

Basic information on rechargeable batteries
One important nominal size of the battery is its capacity. This capacity is measured in ampere hours (AH) or milliamperes hours (mAh). Capacity is described as follows: A battery with a capacity of 800 mAh can supply 800 mA in 1 hour, or 200 mA in 4 hours.

Primary Battery or also known as primary cells. They are intended for single use only and are not rechargeable. They contain two electrodes (anode and cathode) and electrolyte. This can consistof different materials, depending on the type of battery.
