How many times can I recharge my Nimh batteries?
The life of a Nimh rechargeable battery operating under normal conditions is generally around 500 charge-discharge cycles but you may experience more or less depending on the usage conditions and the internal condition of the battery. As a general rule the higher the discharge and charge rates as well as the deeper the discharge between charges the fewer charge/discharge cycles will be obtained. Every time a rechargeable battery goes through a charge and discharge cycle it loses a tiny bit of capacity. The chart on our performance charts page shows a gradual loss of around 3% capacity for each 100 charge cycles. Considering the low replacement cost of Nimh batteries (around .005 cents/charge) the total number of charge cycles obtained may not be cost significant. If your battery eventually stops holding an adequate charge for your application it is time to replace your battery. There are some general rules you can follow to help your batteries last longer.
