Battery Education

What are the differences between battery types?
In simple terms, batteries come in two basic types: single-use and rechargeable.

Single-use batteries, also known as primary batteries, have one life cycle and must be replaced when drained. Examples include alkaline, carbon-zinc, lithium, silver-zinc and zinc air.

Rechargeable batteries, also known as secondary batteries, can be recharged and used repeatedly, Examples of rechargeable batteries include Nickel Metal Hydride (NiHM), Nickel Cadmium (NiCd), Lithium Ion (LiIon) and Sealed Lead Acid (SLA) batteries.
