Preparations
2.2.5 Filling the battery system
Unfilled charged starter batteries are ready for opera-
tions after being filled without any further charging.
When filling the batteries, both the battery and the
acid should have a minimum temperature of 10 °C.
●
Remove the vent plugs.
●
Fill the individual battery cells with sulphur acid
with a density of 1.28 kg/l pursuant to VDE 0510
(for tropical countries 1.23 kg/l) right up to the max-
imum acid level or 15 mm above the upper edge of
the battery plates.
●
Leave the batteries for 15 min, tilt them slightly
several times and refill acid, if necessary.
●
Screw the vent plugs tightly or press them in and
wipe off any acid spillage.
NOTE
If the battery's starting power remains
insufficient due to low temperatures or
unfavourable storage conditions, re-
charge the battery.
Warning notices and safety regulations
●
Wear eye protection.
●
Keep children away from acid and batteries.
●
Risk of explosion
When charging batteries, a highly explosive oxyhy-
drogen gas mixture will be generated. Therefore:
-
Fire, sparks, naked light and smoking are not
permitted.
-
Avoid generating sparks when handling cables
and electric equipment.
-
Avoid short circuits.
●
Risk of chemical burns
Battery acid is highly caustic. Therefore:
-
Wear protective gloves and eye protection.
-
Do not tilt the battery, because acid can leak
from the battery vents.
●
First Aid
-
Rinse acid spills in the eye immediately with
clear water for some minutes and seek medical
advice immediately thereafter.
-
Neutralize acid spills on the skin or clothing
immediately with the help of acid neutralizer or
soapsuds and rinse thoroughly with water.
-
Consult a doctor immediately if you have drunk
acid.

Maintenance
●
Keep the surface of the battery clean and dry.
Clean it with a wet cloth only.
●
Check the acid level regularly and refill demineral-
ised or distilled water, if necessary.
●
Never refill acid.
●
In the event of high water losses, have the control-
ler voltage checked by a specialist.
●
Do not use so-called enhancing agents.
●
The battery's state of charge can be checked with
an acid density measurement. If the acid density
levels below 1.23 kg/l (or 1.18 kg/l in the case of
electrolyte (solution) 1.23 kg/l), the battery needs
re-charging. A battery with this acid density is pro-
tected against freezing in temperatures of up to -15
°C (up to -70°C with a density of 1.28 kg/l).
•
Decommissioning
●
Charge the battery and keep it in a cool place.
●
Should the battery remain in the plant, disconnect
the negative terminal.
●
Check the battery's state of charge regularly.
WARNING
Do not expose batteries unprotected to
direct daylight. Discharged batteries
may freeze, so do store them in a frost-
free place.
●
Disposal:
Hand old batteries in at a collecting point. For the
shipment, observe the regulations of the Road
Shipment Directive for Hazardous Goods (GGVS).
Never dispose old batteries in the household
refuse.
