there is a sensor on the back of the battery sleeve that wraps around the battery. it takes the temp of the battery to check for low or over charging.
my battery light keeps coming on why is that, ive replace the battery and it still happening please help?
No, the battery light is coming on because there is a problem with the charging system. Most likely the alternator is failing. Most auto parts stores will check your system for free.
you need a new battery usally every ten years there is probably a warranty on it chech it out
Have the charging system checked. Possibly loose or corroded wiring, a loose alternator belt, or a bad alternator.
it could mean that you have a loose battery cable that needs to be tightened
Alternator, silenoid, battery cables. After you have checked those 3, try a new battery if its more than 3 years old.
remove neg batteries cable for 15 seconds
