This article provides information about understanding the battery's state of charge. The rechargeable battery is a corrosive device that starts deteriorating as soon as it leaves the manufacturing plant. With the exception of nickel-based batteries, capacity loss is permanent. Aging is based on the shelf life and number of charge/discharge cycles. Depending on the battery type and depth of discharge, a rechargeable battery provides between 100 and 1,000 cycles, with a two- to five-year shelf life.
