How many times can a NiMH battery be recharged?
– Lower capacity rechargeable AA batteries -1700 up to 2000mAh mAh can be recharged up to 1000 times in overnight slow charge mode. 2100 to 2400 mAh rechargeable batteries can be recharged up to 600 to 800 times in overnight slow charge mode. The new Higher Capacity AA 2500 mAh rechargeable batteries have greater power capacity but can only be recharged approx 500 times in the overnight mode. Capacity improvement or quick charging will always decrease the number of cycles. Every cell available on the market above 2100 mAh will have below 1000 charge cycles.
