A secondary battery is commonly known as a rechargeable battery. It is usually designed to have a lifetime of between 100 and 1000 recharge cycles, depending on the composite materials. Secondary batteries are, generally, more cost effective over time than primary batteries, since the battery can be recharged and reused. A single discharge cycle of a primary battery, however, will provide more current for a longer period of time than a single discharge cycle of an equivalent secondary battery.
