The most essential yet overlooked part of any car is the Car Battery. The purpose of car battery is to kick start the engine in every atmospheric condition whether it is cold, hot or wet.

The immediate step to take is to take the car to nearby car battery service station and ask the mechanic to check the CCA rating of the battery. Some of the cars also have the battery meter which needs to be checked whether the volts is properly functioning or not. The battery should maintain 12.4 – 12.8 volts with the engine off without any accessory loaded. With the use of Cold Cranking Amps (CCA), the mechanic will be able to check the capacity of the car battery. If the rating is low then it means it needs immediate charging. If the battery is in good condition, then 25-30 minutes of drive is enough to recharge the battery. If the battery won’t recharge on drive, gets discharged faster or recharging slower, then it is time for a new car battery.
