TEMPERATURE
The operating temperature of the battery affects the capacity available and the life of
the battery.
When temperatures are higher than the nominal 25
o
C the capacity increases and at
lower temperature, decreases. However, increases in temperature can drastically
reduce the expected life. A 10
o
C increase in the average operating temperature can
reduce the life of the battery by 50%.
It is therefore important to install the battery in as cool an area as possible and to
provide good ventilation.
BATTERY MAINTENANCE
The maintenance of the battery is a major factor in the service life achieved. It is
therefore important that the following instructions are followed.
WEEKLY
Check to ensure the charging system is operating within specified limits and
reset if necessary.
Check that the level indicators move freely and that the electrolyte levels are
between the full and low marks. If levels are low, top up with distilled or
deionised water (see Specification for Purity of Topping-up Water) .
Inspect the cells for any apparent signs of failure or problems requiring
immediate repair.
Clean the cell lids with a damp cloth.
MONTHLY
As weekly plus:-
Apply equalising charge.
At the end of the equalise charging period measure and record the cell
voltages, corrected specific gravities and pilot cell electrolyte temperature in
the log book provided.
At end of night discharge period measure and record the cell voltages,
corrected specific gravities and pilot cell electrolyte temperature in the log
book provided.
Check for signs of loose connections and re-tighten where necessary.
