NICKEL-CADMIUM BATTERY
MAINTENANCE
Nickel-cadmium batteries are powerful, rugged
and provide hundreds of charge/discharge
cycles if properly maintained and periodically
"exercised". Exercising is required to recover
most of the capacity lost during usage. This
process reduces the size of the active cadmium
hydroxide crystals on the anode, to expose the
entire surface area and restore capacity.
How to care for your Nickel-cadmium
battery
1.
Never allow a battery to freeze.
2.
Do NOT charge a battery when the work
area or the battery temperature is at or
below 0°C (32° F) or above
45°C (113° F). Allow it to sit at room
temperature for at least 30 minutes before
charging.
3.
Do not charge a battery if it feels warm to
the touch.
4.
Never charge a battery after a short use.
Let it sit until it is needed again.
5.
Never charge the battery until the tool in
which it is being used cannot produce
useful work.
HOW TO EXERCISE A NICKEL-CADMIUM
BATTERY
NOTE:
Ni-Cd and Ni-Mh batteries have a self
discharge rate of approximately 1% per day.
The self discharge rate depends upon the
temperature.
1.
Every two months or after 30
charge/discharge cycles, whichever
comes first, fully discharge your battery.
To fully discharge the battery, place it in
the tool that it came with and work with the
tool until it nearly stops and no longer
produces useful action.
2.
If the tool came in a kit with a worklight,
insert the battery into the light. Turn the
switch ON and leave it ON until the
filament is cherry red.
3.
Let the battery rest for 30 minutes at room
temperature 21°
C (70° F) before
charging.
4.
Charge the fully discharged battery for
approximately 1 hour at 21° C (70° F).
