A common battery in cordless phones and computers is nickel-cadmium. Ever wonder why your nickel-cadmium (NiCad's) don't last as long as they should? You may be overcharging them. Most people's tendancy is to put the phone back on the charger between uses, or to use their laptop plugged-in instead of running down the battery, never letting the battery run down too far. Overtime this will reduce the amount of charge your battery can hold.
