How many times can re-chargeable batteries be charged?

Rechargeable batteries can typically be charged anywhere from 500 to 1,500 times, depending on the type of battery and how well they are maintained. For example, nickel-metal hydride (NiMH) batteries usually last around 500-1,000 charge cycles, while lithium-ion batteries can often handle 1,000 cycles or more. Proper charging practices, such as avoiding deep discharges and extreme temperatures, can help extend their lifespan.
