Charging process for a standard 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.
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 above 50 °C, long-term storage can re-
duce the capacity of the battery pack.
The battery pack cannot be charged outside the permis-
sible temperature range (0 to 50 °C). The battery pack
display shows the temperature symbol when connect-
ed.
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.
1. Plug the plug-in power supply of the charger into the
socket.

ter charging.
4. Unplug the plug-in power supply from the socket.
Note
The charged battery pack can remain in the charger un-
til it is used. There is no danger of overcharging.
Avoid unnecessary energy consumption and unplug the
charger when the battery pack is fully charged.

Loose battery pack
Risk of injury and damage
Ensure that the battery pack engages correctly.
Note
The display shows the remaining run time in minutes
while the device is in use.

Before using the battery pack in a KÄRCHER Battery
Power (+) system, please observe the operating instruc-
tions and safety instructions for the device being used.

Moisture and heat
Risk of damage
Store the battery packs indoors only, at low humidity and
at temperatures below 27°C. If the battery pack is stored
at over 70% power and has not been used for more than
21 days, storage mode is automatically activated, which
partially discharges the battery pack to 70% power.
The battery pack display shows the current charging
state. The display also shows the current charging state
when the battery pack is not connected to a charger.
Illustration C
If the battery pack display goes out during storage, the
battery capacity is fully depleted and the display has
been switched off.
