Maintenance
Your DEWALT Charger has been designed to
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper care and regular cleaning.
Cleaning
• Unplug the charger before cleaning the housing
with a soft cloth.
• Keep the ventilation slots clear and regularly
clean the housing with a soft cloth.
Environment
Battery pack
The long life battery pack must be recharged when it
fails to produce sufficient power on jobs which were
easily done before. At the end of its technical life,
discard it with due care for our environment:
• Run the battery pack down completely,
then remove it from the tool.
• NiCd and NiMH cells are recyclable. Take them
to your dealer or a local recycling station.
The collected battery packs will be recycled or
disposed of properly.
Charger
At the end of its technical life, take your charger to
an authorized DEWALT repair agent where it will be
disposed of in an environmentally safe way.
Do not charge the battery pack at
ambient temperatures < 4 °C or > 40 °C.
Recommended charging temperature:
approx. 24 °C.
• To charge the battery pack (3), insert it into the
charger (1) as shown and plug in the charger.
Be sure that the battery pack is fully seated in the
charger. The red charging indicator (2) will blink.
After approx. 1 hour, it will stop blinking and
remain on. The battery pack is now fully charged
and the charger automatically switches to
equalization mode. After approx. 4 hours, it will
switch to maintenance charge mode. The battery
pack can be removed at any time or left in the
connected charger indefinitely.
• The red charging indicator flashes rapidly to
indicate a charging problem. Reinsert the battery
pack or try a new one. If the new pack also
refuses to charge, have your charger tested by
an authorized DEWALT repair agent.
• When plugged into power sources such as
generators or sources that convert DC to AC,
the red charging indicator (2) may blink twice,
switch OFF and repeat. This indicates a temporary
problem of the power source. The charger will
automatically switch back to normal operation.
Equalization mode
The equalization mode helps to maintain the optimum
capacity of the battery pack. It is therefore
recommended to use the equalization mode monthly
or every 20 charge/discharge cycles.
• Charge the battery pack as described above.
• When the charging indicator stops blinking, leave
the battery in the charger for approx.
4 hours.
DE9108/DE9116 - Hot Pack Delay
When the charger detects a battery that is hot,
it automatically starts a Hot Pack Delay, suspending
charging until the battery has cooled. After the battery
has cooled, the charger automatically switches to the
pack charging mode. This feature ensures maximum
battery life. The red indicator (2) blinks long,
then short while in the Hot Pack Delay mode.
