Two Wheeler Batteries

History of Battery

The first battery was created by Alessandro Volta in 1800. The main purpose of a standard automotive battery is to provide power to a vehicle's starter. The three most important things about a automotive battery are its amp/hour rating, its chemistry and its voltage.

Characteristics of Battery
  • Battery has two terminals: One(+), or positive and the other(-), or negative.
  • Battery is the vehicle's initial source of energy used to start the engine.
  • A typical two wheeler can be rated at 12 amp/hour.
  • On an average, a two wheeler battery last about three years.
  • Battery acid is very corrosive and will eat through metal.
Functions of Battery
The main functions of a battery are as:
  • Two wheeler battery enables the engine to start with the electrical starter.
  • It works as an extra power supply when the vehicle needs it.
  • It is used for operating the lighting and accessory systems.
  • It acts as an electrical shock absorber, protecting vital electrical components from burning out during high voltage/current output.
Maintenance of Automotive Battery
  • During winter season a charger should be used to keep it topped.
  • The battery should be checked to see if they are securely fitted, the cables are attached securely and the vent hose routed properly.
  • When charging a battery, it should never exceed one-tenth of the rated amp-hour capacity.

Recently Amaron introduced batteries for Two wheelers. Which gives 4 yrs of warranty. Exide is there in market for quite some time, which gives warranty only for a year. Even other brands like AMCO, EPower, USHC, BOSCH, SVMF are too not provding 4 years of warranty. Amaron charges bit more than others but gives 4 yrs of warranty where no other brand in the market gives such long warranty.

So I vote for AMARON BATTERIES!!!
