Using batteries made by other manufac-
turers
We recommend using our batteries as de-
scribed in chapter "Care and Maintenance/
Recommended batteries".
Note
While using other batteries (for e.g. batter-
ies from other manufacturers) the total dis-
charge protection level must be reset by
the Kärcher after sales service according to
the respective battery.
Charging battery
Note
The appliance is equipped with a safety
mechanism to prevent total discharge, i.e.
when the permissible minimum capacity is
reached, the brush motor and the turbine
are switched off.
Drive the machine directly to the charg-
ing station; avoid any steep gradients in
the process.
DANGER
Risk of injury on account of electric shock.
The mains voltage must correspond with
the type plate on the appliance.
Use the charger only in dry rooms with suf-
ficient ventilation!
Charging process
Average charging time is approx. 10 -15
hours.
The built-in charger has electronic controls
and is suitable for all recommended batter-
ies; it automatically switches off the charg-
ing process.
The built-in battery is shown on the display
during the charging process. If this is not
the case, the charging marker line must be
selected (see "Setting the charging marker
line").
The appliance must not be used during the
charging process.

Initial charge tips
With the initial charge, the control will not
yet be able to detect which battery type has
been installed. Keep charging the batteries
until the display shows a full charge (batter-
ies may still not be completely charged).
The next charging process will have an ac-
curate display and charge power and the
batteries will be fully charged.
Use the appliance until the deep discharge
protection switches off the brush motor and
the turbine after the initial charge of the bat-
tery. This procedure is necessary to adjust
the battery indicator. Only then the correct
battery status is displayed.
Insert the plug of the connecting cable
into the socket. The charging process
will start.
Note: The selected battery will be dis-
played during charging.
Charge until the display shows a full
charge.
Low maintenance batteries (wet batter-
ies)
WARNING
Danger of caustic material!
Adding water to the battery in its dis-
–
charged state can cause the acid to
leak.
Use safety glasses while handling bat-
–
tery acid and follow the safety instruc-
tions to avoid personal injury or damage
to clothes.
Should the acid spray on to the skin or
–
clothes, rinse immediately with lots of
water.
CAUTION
Risk of damage!
Use only distilled or desalinated water
–
(EN 50272-T3) for filling the battery.
Do not add any substances (so-called
–
performance improving agents), else
warranty claims will not be entertained.
Replace batteries only with batteries of
–
the same type. Otherwise, the charging
guideline must be readjusted by cus-
tomer service.
