BATTERY CARE
If the battery is still dry, it must be activated as
described in section
The battery must be in operation within 2 months
from being activated; if not, it needs to be recharged
first.
ELECTROLYTE
Electrolyte in batteries is a sulphuric acid solution in
distilled water.
The solution must be made up before being
introduced into the battery.
ACTIVATING A DRY-CHARGED BATTERY
Take out the battery.
Battery and electrolyte must be at equal
temperature above 10 °C (50 °F).
Remove cover and/or plug from each cell.
Fill each cell with electrolyte until the level
reaches 10 mm (0.4 in) to 15 mm (0.6 in) above
the plates, or to the level marked on the battery.
Rock the battery a few times so that possible air
bubbles can escape; wait 10 minutes and check the
level in each cell once more; if required, add
electrolyte.
Refit plugs and/or cover.
Place the battery in the compressor.
RECHARGING A BATTERY
Before and after charging a battery, always check the
electrolyte level in each cell; if required, top up with
distilled water only. When charging batteries, each
cell must be open, i.e. plugs and/or cover removed.
Preferably use the slow charging method and adjust
the charge current according to the following rule of
thumb: battery capacity in Ah divided by 20 gives
safe charging current in Amp.
MAKE-UP DISTILLED WATER
The amount of water evaporating from batteries is
largely dependant on the operating conditions, i.e.
temperatures, number of starts, running time between
start and stop, etc.
If a battery starts to need excessive make-up water,
this points to overcharging. Most common causes are
high temperatures or a too high voltage regulator
setting.
If a battery does not need any make-up water at all
over a considerable time of operation, an
undercharged battery condition may be caused by
poor cable connections or a too low voltage regulator
setting.
Before handling batteries, read the
relevant safety precautions and act
accordingly.
Read the safety instructions carefully.
Use a commercial automatic battery
charger according to its manufacturer’s
instructions.
