the battery label.
All cells must produce gas at the end of
the charging process.
Maintenance-free batteries (AGM and
gel batteries)
ATTENTION
Risk of damage when opening AGM and
gel batteries!
AGM and gel batteries are maintenance-
free and have a closed battery housing. Re-
filling them with distilled water or battery ac-
id is not possible and is not necessary.
Opening or drilling the battery housing will
damage an AGM or gel battery. It must then
be replaced.
Do not open the battery housing and do not
drill any holes.
Do not cover the pressure relief valve and
do not change it.
1. Only charge AGM and gel batteries us-
ing the specified chargers, see chapter:

Only use the charger in dry rooms with suf-
ficient ventilation.
ATTENTION
Accumulation of dangerous gases un-
der the tank during the charging pro-
cess
Risk of explosion
Pivot the waste water tank upwards before
charging low-maintenance batteries.
ATTENTION
Using an unsuitable charger
Risk of damage
Do not connect the charger to the device-
side battery connector.
Use only a charger suitable for the type of
battery installed.
Read the operating instructions of the
charger manufacturer and observe the
safety instructions in particular.
The average charging time is approx. 10-
15 hours.
The device cannot be used during the
