Charging process for a fast charger CAUTION
Risk of injury, risk of damage! Observe the operating instructions 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 process. To ensure that the charge level indicator works correctly, the battery pack must be discharged during initial use until the device is switched off.
Plug in the mains plug. Slide the battery pack onto the intake. The charging process begins automatically.
The indicator lamp glows green. The remaining charging time is displayed on the battery pack display. When the battery pack is fully charged, the display shows 100%. After charging, remove the battery pack from the charger. Pull out the mains plug.
Note
If the display does not show anything when the battery pack is in the charger, the battery capacity is fully depleted or very low. As soon as the battery pack has been sufficiently
charged, the display shows the remaining 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 temperatures 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.
