when do i know that my battery is about to change.

[khandelwal]

how can i find out when my battery needs changing? does it depend on the age or what?

the battery of b JC is around 4 years old it was a very good quality one but somehow i cant recall its life.

The life of the battery lasts from 3 years to 5 depending on the extreme temp. but the sad part is there is no way to figure out how long will the battery last. to my advise i think its better to wait till you start see that the car battery is dieing. that will be a good time to change.

As cranking the car chew most battery power. Every batter keep reserve cranking amp written on battery.
