Use only batteries approved by the phone manufacturer andrecharge the battery only with the chargers approved by the manufacturer.Unplug the charger when not in use. Do not leave the battery connected to a charger forlonger than a week, since overcharging may shorten its lifetime.If left unused a fully charged battery will discharge itself over time Temperature extremescan affect the ability of your battery to charge.For good operation times with Ni-Cd/NiMh batteries, discharge the battery from time totime by leaving the product switched on until it turns itself off (or by using the batterydischarge facility of any approved accessory available for the product).Do not attempt to discharge the battery by any other means Use the battery only for itsintended purpose.Never use any charger or battery which is damaged.Do not short-circuit the battery.
