As an electrical system all the components cannot be designed to be an ideal product in nature. There are many reasons in which the two wheeler battery may leads to the failure. However we may prevent the failures by taking care of such simple steps given below.
A low electrolyte level exposes active material, and any sulfate hardens and resists chemical action. Loss of electrolyte may be caused by cranked case, poor maintenance or severe over charging which causes high internal heat and excessive gassing. Too much electrolyte is just as bad. Overfilling may dilute battery electrolytes and spillage may corrode battery terminals.
Overcharging by the vehicles charging system or separate battery charger causes excessive gassing and high internal heat. Too much gassing can damage the active materials off the plates, as well as cause excessive water usage. Too much heat can oxidize the positive plate material and wrap the plates, which shrinken’s the two wheelers battery life.
A faulty charging system will not maintain the battery at full charge, where the battery will not be able to provide the full efficiency. Severe under charging allows sulfate on the plates to become hard and impossible to remove by normal charging. The weak electrolytes freeze easier. The undercharged two wheeler battery may fail to crank the engine because of its low charge in it.
Spilled electrolyte and condensation from gassing may cause corrosion on terminals, connectors, and metal holders. Such corrosion increases electrical resistance, which reduces the available voltage and charging effectiveness. It may also create a current leakage path to allow self discharge of the two wheeler battery.
Repeated cycling from fully charged to fully discharged and back may cause loss of active materials from the positive plates. This drastically reduces battery capacity and its useful life.
High temperature from over charging or engine heat can shorten battery life. Low temperatures can cause freezing of weak electrolyte. At 0 degree Fahrenheit a fully charged battery provides less than half its normal power. At same time, the cold engine requires twice as much cranking power as it does with normal temperatures. The electrolyte in the fully charged battery will not freeze until – 60 degree Fahrenheit or lower, while the electrolyte in a fully discharged battery will freeze at + 18 degree Fahrenheit.
A battery must be mounted securely. Vibration can loosen up connections, crack the case and damage internal components.
