CHAPER 10 - SERVICE INSTRUCTIONS
10.2 BATTERY MAINTENANCE
Fluid level check
The fluid level in the batteries must be checked
every 100 operating hours (figure 10.2.1). The level
should be approximately 10 mm(1/4") above the
plates. Add clean distilled water as required.
Monitoring the fluid consumption will give an
indication of the charge of the battery, but a
separate test of the specific gravity of the acid will
confirm the state of charge. If the fluid
consumption is high it is possible for the alternator
charging rate to be too high.
Figure 10.2.1 Check battery fluid level every 100
operating hours. Add clean distilled water in the
accumulator as required
Battery check
The level of charge in the battery must be checked
regularly using a hydrometer. Do not make this
check immediately after adding any distilled water
to the battery; the water and acid will be more
evenly mixed after some charging has taken place.
The specific gravity of a fully charged battery is
approximately 1.28, and if only half-charged the
reading will be about 1.2. These values relate to a
battery temperature 20ºC(68ºF).
Batteries must always be maintained as far as
possible at full charge. If the charge is allowed to
remain low, the plates will become sulphated
reducing the capacity and efficiency of the whole
battery.
Remember that a half-charged battery will freeze at
a temperature of -25ºC(-13ºF) and a flat one at only
-10ºC(14ºF).
Never use an open flame when checking the acid
level of a battery. The gases given off by the
chemical reaction during the recharging process are
highly inflammable.
The liquid used in lead-acid batteries is dilute sulf
acid. This acid is corrosive, will cause severe burns
to exposed skin and will damage clothing. Be very
careful when handling a battery.
Always wear protection glasses and gloves while
handling and maintaining.
Cleaning batteries, terminals and cables
Batteries and terminals must be cleaned at least
once per year. The terminals and the cable ends
should be cleaned with the special tools which will
restore the contact area to the right form and size.
After cleaning, the terminals and cable ends should
be liberally covered with petroleum jelly to protect
against oxidation. Check also the fastening of:
battery earth cables to the main frame, engine
starter cables, and electrical connections for the
alternator. Clean and tighten as necessary. Keep
battery cases clean and dry.
