All About Batteries. In order to explain how rechargeable batteries work, it is important to understand how batteries of any type work, both rechargeable and non-rechargeable. It turns out that batteries are less about electricity and all about chemistry.oes not fully recharge, so that the battery capacity shrinks rapidly with each charge cycle. Some will completely die after as few as ten charge cycles. Lithium-ion (Li-ion, LIB). Rechargeable and efficient. These batteries are often used in quality laptops, cell phones, and other digital devices.
