Improving Battery Performance
Follow these guidelines to extend battery life.
– Replace all four batteries at the same time. Mixing new or fully
charged batteries with those that have been in use for some time
weakens the new ones.
– Clean the contacts in the battery compartment periodically by
rubbing them gently with a clean pencil eraser or a cloth.
– Keep batteries away from heat. For example, do not leave
batteries in a car in hot weather.
– Store batteries at room temperature and keep them dry.
– Recharge NiCad batteries if they have not been used after
six months.
Battery Safety Information
Follow these guidelines when handling batteries.
– Always handle batteries carefully.
– Do not drop, puncture, disassemble, mutilate, or incinerate batteries.
– If you touch both terminals of a battery with a metal object, the
battery will short circuit and possibly cause an explosion or a fire.
Do not carry loose batteries where the contacts may touch metal
objects such as coins or keys.
– Do not heat batteries to try to rejuvenate their charge.
