Improving Battery Performance
Follow these guidelines to extend the life of batteries.
– 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
the trunk of 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.
