Maintenance Section

The battery’s maximum temperature is critical. The
electrolyte temperature should never exceed 43°C
(110°F) either while operating or charging. If higher
temperatures are maintained through use or abuse,
reduced battery service life can be expected.
Battery condition is important for a long life. The
electrolyte level should be maintained at the
recommended levels and the battery should be kept
clean and dry. “Washing down” batteries at different
time periods will reduce the chance of “grounds”
caused by electrolyte spills and corrosion. If done
often enough, just washing with water alone will
eliminate the need for using baking soda. If not, a
solution of baking soda and water must be used to
wash battery at different time periods.
Add water at regular intervals. Enough water should
be added to bring the electrolyte approximately
13.0 mm (.50 inch) above the plates. This is a
simple matter with the use of an automatic cell filler,
which shows a light when the correct level has
been reached. Water should always be added
before charging to be sure thorough mixing with
acid when gassing occurs near the end of charging
period. Use distilled water or have the water supply
analyzed.
Charge batteries correctly. It is important that all
batteries should be charged according to the
manufacturer’s instructions. Most of the charging
equipment is fully automatic and should be checked
periodically. Never operate the lift truck with a fully
discharged battery because this will damage the
battery.
When a battery charger operates correctly and
brings a good battery up to full charge, the current
readings will level to the “finish rate.” The charging
voltage will stabilize, the specific gravity will stop
rising and normal gassing can be seen.
NOTICE
• DISPOSAL OF OLD BATTERY
Careless disposal of a battery can harm the
environment and can be dangerous to persons.
Always dispose of a battery to an authorized
personnel only.
Do not attempt to open or dismantle a battery or a
cell.
