Batteries, Cables And Connections - Vetus EP2200K Manuel D'utilisation

Maintenance
Keep the batteries clean and dry. Cleaning
is best done with a slightly damp cloth or
sponge.
Disconnect the battery cables during
maintenance (remove the negative (-)
earth cable first.
Lubricate the battery terminals with acid-
5
free Vaseline. Clean corroded battery ter-
minals with warm caustic soda solution
(rinse thoroughly!).
Take care that the battery terminals make
good contact after fitting. Tighten the bolts
finger tight only.
Check that all connectors and cables are
fitted properly; loose connections can
cause problems, and even a danger of
explosion under certain conditions. When
the batteries are not going to be used
for some time (holiday - winter lay-up
- repairs) ensure that the batteries are
fully charged. When not used for a long
period, recharge the batteries every 3
months. When the battery voltage is 24.8
Volts or less when not operational, charge
immediately.

Check electrolyte level
The electrolyte is a mixture of chemi-
cally-pure sulphuric acid and pure water.
During charging, the water alone can par-
tially decompose and escape as gas.
So top up only with distilled or chemically
purified water.
The correct filling level; after topping up
and/or charging, is about 15 mm above
the plates. Check this level regularly and
top up as required using a clean fun-
nel. Over-filling can cause 'boiling' when

charging, causing acid loss and current
leakage. Specific gravity measurements
made shortly after topping-up give a false
reading, the topping-up water should be
well mixed by charging.
