When charging the battery pack for the first time, or
after prolonged storage, it will only accept an 80%
charge. After several charge and discharge cycles,
the battery pack will attain full capacity.
Always check the mains prior to charging the battery
pack. If the mains is functioning but the battery pack
does not charge, take your charger to an authorised
D WALT repair agent. Whilst charging, the charger
E

ambient temperatures < 4 °C or > 40 °C.
Recommended charging temperature:
approx. 24 °C.
• To charge the battery pack (11), insert it into the
charger (13) as shown and plug in the charger.
Be sure that the battery pack is fully seated in the
charger. The red charging indicator (14) 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
equalise 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

• When plugged into power sources such as
generators or sources that convert DC to AC, the
red charging indicator may blink twice, switch off
and repeat. This indicates a temporary problem
of the power source. The charger will

Inserting and removing the battery pack (fig. B1)
• Insert the battery pack (11) into the tool until it
clicks in place.
• To remove the battery pack, press the two
release buttons (12) simultaneously and pull the
pack out of the tool.
Battery cap (fig. B2)
A protective cap is supplied to cover the contacts of
a detached battery pack. Without the protective cap

contacts, causing a fire hazard and damaging the
battery pack.
• Take off the protective cap (12) before placing
the battery pack (24) in the charger or tool.
• Place the protective cap over the contacts
immediately after removing the battery pack from
the charger or tool.
Make sure the protective cap is in place
before storing or carrying a detached
battery pack.
Equalization mode
The equalization mode helps to maintain
the optimum capacity of the battery
pack. It is therefore recommended to
use the equalization mode weekly or
every 10 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.
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.
