below 10 °C or above 40 °C. Recommended charging tem-
perature: approx. 24 °C.
Note: The charger will not charge a battery if the cell
temperature is below approximately 0 °C or above 40 °C.

(Original instructions)
To charge the battery (22), insert it into the charger (23).
u
The battery will only fit into the charger in one way. Do
not force. Be sure that the battery is fully seated in the
charger.
Plug in the charger and switch on at the mains.
u
The charging indicator (24) will flash green continuously
(slowly).
The charge is complete when the charging indicator (24)
lights green continuously. The charger and the battery can be
left connected indefinitely with the LED illuminated. The LED
will change to flashing green (charging) state as the charger
occasionally tops off the battery charge. The charging indica-
tor (24) will be lit as long as the battery is connected to the
plugged-in charger.
Charge discharged batteries within 1 week. Battery life will
u
be greatly diminished if stored in a discharged state.
Leaving the battery in the charger
The charger and battery pack can be left connected with the
LED glowing indefinitely. The charger will keep the battery
pack fresh and fully charged.
Charger diagnostics
If the charger detects a weak or damaged battery, the charg-
ing indicator (24) will flash red at a fast rate. Proceed as
follows:
Re-insert the battery (22).
u
If the charging indicators continues flashing red at a fast
u
rate, use a different battery to determine if the charging
process works properly.
If the replaced battery charges correctly, the original bat-
u
tery is defective and should be returned to a service centre
for recycling.
If the new battery gives the same indication as the original
u
battery, take the charger to be tested at an authorised
services centre.
Note: It may take as long as 30 minutes to determine that
the battery is defective. If the battery is too hot or too
cold, the LED will alternately blink red, fast and slow, one
flash at each speed and repeat.
