Please observe the following warning notes 
when handling batteries:



Danger

Danger of explosion. Do not put tools or 
similar on the battery, i.e. on the terminal 
poles and cell connectors.
Risk of injury. Ensure that wounds never come 
into contact with lead. Always clean your hands 
after having worked with batteries.

The BP package model contains a built-in 
battery.

Î

Tilt the water tank backwards.

Î

Insert the battery in the trough.

몇

Warning

Pay attention to correct poles. 

Î

Connect the connection cable to the 
free battery poles (+) and (-).

Î

Tilt the water tank towards the front.

몇

Warning

Charge the battery before commissioning 
the machine.

Note

The device is equipped with a safety mech-
anism to prevent total discharge, i.e. when 
the permissible minimum capacity is 
reached, then the machine can only be 
driven and existing lamps can be switched 
on. In such a case, the battery monitoring 
symbol on the control console glows red.

Î

Drive the machine directly to the charg-
ing station; avoid any steep gradients in 
the process.

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 aftersales service according to 
the respective battery.



Danger

Risk of electric shock. Observe supply net-
work and fuse protection - see "Charger".
Only use the charger in dry rooms with suf-
ficient ventilation!

Note

Average charging time is approx. 10 hours. 
The recommended chargers (matching the 
batteries used) are regulated electronically 
and will automatically switch off the charg-
ing process.



Danger

Danger of explosion. Wet batteries can 
only be charged with opened hood.

Î

Empty the dirt water reservoir.

Î

Tilt the dirt water tank backwards.

Î

Remove battery plug and join it to the 
charging cable.

Î

Connect the charger to the mains and 
turn it on.

Î

Switch off the charger and remove the 
plug from the socket.

Î

Pull the battery cable from the charger 
cable and connect it to the machine. 

Î

Add distilled water one hour before the 
charging process comes to an end; fol-
low the correct acid level.  There are 
corresponding indicators on the battery.  
At the end of the charging process, all 
cells must gas. 



Danger

Danger of causticization!

–

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.

몇

Warning

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. 

Batteries and chargers are available in spe-
cialised stores.
