7.5 Batteries
Electrical vehicles require special drive
batteries.
7.5.1 Unsealed batteries
Lead acid batteries (with electrolyte)
have screw-on caps. The battery acid
level must be checked regularly.
7.5.2 Sealed batteries
Sealed batteries (with gel or fleece) may
not be opened. They are maintenance-
free and the acid cannot leak during
transport.
7.5.3 Battery charging
The batteries must be charged before
the first journey. See the 'Batteries' sec-
tion in the Operating manual for control
units for information.
7.5.4 Battery replacement
The daily use of the electric wheelchair
places a high demand on the drive bat-
teries, they can only fulfil their function
when they are maintained and charged.
Batteries undergo a normal ageing proc-
ess. Both batteries must be replaced
when they no longer give the full power
or are defective despite correct charg-
ing.
The use of batteries with different ca-
pacities is not permitted.
Note:
Have a battery replacement carried
out by a specialist workshop because
they know about the possible risk situ-
ations and can correctly dispose of
defective batteries.
7.5.5 Safety information
Keep children away from batteries,
accessory parts and packing mate-
rial.
Avoid open flames and sparking in
the proximity of the batteries.
– Risk of explosion!
Switch off the control unit and then
pull out the main fuse before start-
ing work on the electrical equipment.
Never touch the battery terminals
with tools, cable ends or other metal
objects when working on the batter-
ies.
Attention:
!
Batteries can explode if they come
into contact with sparks, e.g. due to
a short circuit of the battery termi-
nals!
Caution:
!
Battery acid is very caustic! Skin and
eyes can be injured, clothing and
flooring can be damaged.
