Charging process

Note
Charge the battery packs Battery Power (+) 18/25 and
18/50 with battery pack chargers for the KÄRCHER
18 V Battery Power Platform only.
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.
On first use, discharge the battery pack until the device
switches off so that the charge indicator functions cor-
rectly.
New battery packs reach their full capacity after approx.
5 charging and discharging cycles.
Charge battery packs that have not been used for a long
time before use.
At temperatures below 0 °C, the capacity of the battery
pack decreases.
At temperatures below -20° C and above 60 °C long-
term storage can reduce the capacity of the battery
pack.
If the display does not show anything during charging,
the battery capacity is fully depleted or very low. Display
shows remaining charging time once the battery pack is
sufficiently charged. If the display does not show any-
thing even after a longer period of time, the battery pack
is defective. Replace the battery pack.
