BATTERY MAINTENANCE :
For the optimum performance and longer battery life
the maintenance of battery is important. The condition
of the battery should be checked at least once in a
month as follows :-
a) Always keep the battery clean and dry.
b) Visually inspect the surface of the battery container.
If there are any signs of cracking or electrolyte
leakage from battery, replace the battery.
c) Battery electrolyte level inspection—The electrolyte
level inside all the six cells should be checked fort-
nightly and topped up if necessary as per procedure
given below:-
i) Remove LH side cover. Remove battery holding band.
Remove battery after removing cables.
ii) Check whether the electrolyte level of each cell is
between the upper and lower level lines. If the level
is low in any of the cells then top-up with dis- tilled
water as follows :
• Remove the battery from vehicle.
• Remove filling caps fill distilled water until
electrolyte level in each cell reaches upper level .
“NEVER ADD ACID OR ORDINARY TAP WATER FOR
TOPPING UP SINCE THIS WILL SHORTEN
BATTERY LIFE”.
• ALWAYS KEEP THE EXHAUST TUBE FREE FROM
OBSTRUCTIONS.
NON-USE MAINTENANCE :
When the vehicle is likely to remain off-road for a longer,
time (say more than a month) then non-use maintenance
should be carried out as follows otherwise the battery
may get sulphated and permanently damaged.
a) Remove the battery from vehicle.
b) Maintain electrolyte at “UPPER LEVEL”.
c) During off service period, battery should be charged
once a month.
d) Keep the battery fully charged.
e) Store the battery in cool, dry place.
f) Keep the battery away from rain, dew, moisture and
direct sunlight.
BATTERY SULPHATION :
A sulphated battery is one which has been left standing
in a discharged condition or undercharged to the point
where abnormal lead sulphate has formed on the plates
(Sulphated cells looks like white crystal like sugar).
Where this happens, the chemical reactions within the
battery are affected and results in loss of capacity.
Mostly the causes of sulphation are as under :-
a) Undercharging.
b) Standing in a partially or completely discharged
condition for long time.
c) Low electrolyte level: if electrolyte level is permitted
to fall below the top of the battery plates, then the
exposed surfaces will harden and will become
sulphated.
d) Adding acid:if acid is added to-a cell in which
sulphation exists the condition will be aggravated.
e) High specific gravity:if specific gravity is higher than
the recommended value, then sulphation may occur.
f) High temperature : high temperature accelerates
sulphation, particularly of an idle, partially discharged
battery.
Voltage of the sulphated battery :-
Cells of the sulphated battery will show low specific
gravity . Follow the procedure given below.
i)
Check voltage before charging.
ii) Charge for 2 hours.
iii) Check voltage every one hour. If voltage increases
then continue charging. But if voltage does not
increase the discontinue charging otherwise battery
charger will get permanently damaged.
If battery is not badly sulphated (i.e. voltage more than
9 volts), then battery can be revived by special
treatment. In such case it is advisable to give sulphated
battery to battery specialists for necessary special
treatment.
HOW TO DETERMINE CONDITION OF BATTERY :
Specific gravity check :- Whether battery is fully charged
or partially charged, it will always show same “no load
voltage” of 12 volts or more (unless battery cells are
damaged due to sulphation etc). But specific gravity of
the fully charged battery and partially charged battery
will be different. Fully charged battery will show specific
gravity of 1.240 in tropical climate and 1.28 in cold
climate while partially charged battery will show less
specific gravity. Therefore, specific gravity check is
very important to know condition of the battery.
SAFETY :
Never bring the naked flame or spark such as a candle,
lighted cigarette etc. near the battery, especially during
or shortly after charge. Battery charging room should
be well ventilated -
NOTE : These are general guidelines.
