How do I prolong the lifespan of my rechargeable telephone batteries

Your AAA NiMh rechargeable battery is charged during production in order to test it. Your battery will discharge between the end of the production and the moment you receive it. That is why your battery will have to be charged before you use it. You must use your cordless phone to charge your new AAA battery for 12 to 24 hours before using your phone; this will prolong the life of your battery.

Rechargeable aaa batteries for cordless phones will discharge slowly when not in use. The self-discharge rate is about 1% of the battery’s capacity per day at room temperature. The higher the temperature, the faster your battery will discharge. If you intend to leave your battery for a prolonged period without use then a service charge is recommended. Simply take in to account the self-discharge rate and time between use. You can read more about how to maximise the lifespan of your new NiMh rechargeable battery here.
