The three main functions of the automotive
battery are to:
power to the starter and the ignition system so that the engine can be cranked
the charger system when load requirements exceed the supply capability of the
3.Act as a
voltage stabilizer in the electrical system. The battery smoothies out or
reduces temporarily the high voltages which may occur in the system, thereby
protecting voltage sensitive components
·Faulty regulator settings resulting
in severe overcharging causes the positive plates to disintegrate and the
battery to lose power.
·Faulty regulator settings or a
loose fan belt resulting in undercharging causes plates to sulphate and reduces
performance. If left unattended for prolonged periods, the sulphation becomes
irreversible and the battery permanently short of capacity.
Dirty and corroded terminals:
·Faulty connections produce high
resistance and consequent voltage drops resulting in poor starting and charging
·Batteries that are not held
securely will suffer excessive vibration which can dislodge active material
from the grid or break the inter-cell weld.
Over tightening of clamps:
·Excessive tightening of hold-down
clamps can cause the battery container to crack resulting leakage of
electrolyte. Not only is the battery ruined, but other components are damaged
due to corrosion from the acid.
Incorrect Fitment of terminals:
·Using force when fitting
connections to the battery (e.g. hammering on of terminals to the battery
positive and negative poles) can damage the internal connections or damage the
poles. Always loosen connections properly with the correct size spanners before
connecting or disconnecting the terminals.
A battery should have the electrolyte kept at the correct level.
A battery should not be exposed to excessive shocks or vibrations.
