battery. On receiving this signal, the car battery converts chemical energy into electrical
energy. This electrical power is delivered to the starter to crank the engine. The battery also
provides power to the car’s lights and other accessories.
battery is weak. If you can’t test the battery, try jump-starting. If the car starts right-away,
the problem is most likely a dead battery. If the car does not start by jump-starting, there
may be a problem with starter, alternator or other components of the electrical system.
snug and protected from the elements. Signs of corrosion or leaks could mean that the
battery is no longer operating optimally.
Make sure that the hold-down bar is secure in its place. If the battery is snugly seated, it
minimizes vibrations which can be detrimental to certain types of batteries.
The battery should be routinely tested to make sure it is optimally charged. If the battery is
weak, it should be recharged so as to maintain its peak performance. The recharge time
depends on the battery condition.
There could be many causes of battery failure, the main ones are as follows :
High Temperature : Heat accelerates grid corrosion in the positive plate, leading to loss in
capacity and starting power.
High vibration : Vibration can damage and separate internal components.
Faulty alternator : A faulty alternator can lead to an undercharged or completely
Wrong application : The battery is not being used in the application for which it was
Wrong size : The battery is not sized properly for the application. The replacement battery
should be of same or more capacity as compared to the original battery.
Poor installation and maintenance : The battery is not properly installed. The battery cables
have not been cleaned and properly adjusted to fit the battery terminals.
Failure to recharge : After drops in voltage, the battery should be recharged promptly;
failure to do so can deteriorate the battery condition and life.
It is advisable to purchase battery of a reputed brand and to get it installed in a
professionally-managed outlet with trained technicians.
