CAUTION
Risk of injury, risk of damage! Observe the operating in-
structions and safety instructions of the charger.
Note
New battery packs are only pre-charged and must be
fully charged before first use.
The display is activated during the first charging pro-
cess.
To ensure that the charge level indicator works correct-
ly, the battery pack must be discharged during initial use
until the device is switched off.
Illustration
Plug the plug-in power supply into the socket.
Push the battery pack into the battery adapter of
the charger.
The charging process begins automatically.
Illustration
The remaining charging time is displayed on the
battery pack display.
The charging time with a standard charger (Battery
Power BC 36 V) for an empty battery pack (Battery
Power 36/25) is approx. 5,5 hours.
When the battery pack is fully charged, the display
shows 100%.
Remove the battery adapter from the battery pack
after charging.
Pull the plug-in power supply from the socket.
Note
If the display does not show anything when the battery
pack is in the charger, the battery capacity is fully de-
pleted or very low. As soon as the battery pack has
been sufficiently charged, the display shows the re-
maining charging time.
If the display does not show anything even after a
long period of time, the battery pack is defective
and must be replaced.
Note
New battery packs reach their full capacity after approx.
5 charging and discharging cycles.
Charge batteries that have not been used for a long time
before use.
The performance of the battery pack is reduced at tem-
peratures below 0°C.
The capacity of the battery pack may be reduced if
stored at temperatures over 20°C.
Note
The charged battery pack can remain on the charger till
it is to be used. There is no risk of over-charging.
In order to avoid unnecessary energy consumption, the
charger should, however, be unplugged as soon as the
battery pack has been fully charged.
