The three main functions of the automotive battery are to:
Supply power to the starter and the ignition system so that the engine can be cranked and started.
Supplement the charger system when load requirements exceed the supply capability of the alternator.
Act as a voltage stabilizer in the electrical system. The battery smoothies out or reduces temporarily the high voltages (transients) 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 efficiencies.
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.
