Ways to improve battery performance
Here are some tips that may help you get the most from your batteries.
m When you replace used batteries, replace all the old ones with new ones.
Mixing new and used batteries weakens the performance of the new ones.
(If you are using rechargeable batteries, replace batteries that are running
low with a complete set of fully charged batteries.)
m Batteries work best when the contact surfaces are clean. If necessary, clean
these surfaces by gently rubbing with a clean pencil eraser or a cloth.
Rechargeable NiCad batteries
If you’ve used a set of rechargeable batteries for a while, and they seem not to
last as long as when they were new, discharge them completely before
recharging them. Unless the batteries are wearing out, this should improve
their lasting power.
WARNING Damaged nickel-cadmium (NiCad) batteries may leak small
amounts of potassium hydroxide. This substance can cause severe burns
to the skin and eyes. If you touch a damaged battery, immediately rinse
your hands and any other affected areas with water for at least 5
minutes. Do not use soap.
