Checking the acid level
The battery acid level falls due to evap-
oration of water, especially during
high ambient temperature.
☞
Note:
Top up to the correct acid level with
distilled water if necessary.
The acid level is correct when it is
– just above the filling hole insert or
– approx. 5 mm above the top edges
of the plates (fig. 76).
☞
Note:
Maintenance-free batteries:
Vent plugs are not visible. – These
batteries do not require mainte-
nance. Acid level cannot be meas-
ured.

▲
Do not tilt open batteries. – If acid
leaks out there is a danger of acid
burn.
▲
Protect the eyes from acid spray by
wearing goggles and wear gloves
when checking or topping up un-
sealed batteries.
▲
Use only distilled water for topping
up unsealed batteries.
▲
Use a metal funnel for filling or
topping up. – Danger of short cir-
cuit.
