Customer Question

Good Afternoon!
I own Nissan Altima Hybrid 2009. Bought brand new from a dealer. My carwould not start even after a drive so they upgraded the battery and added insulation to body ground. Tested new battery, good, Power drainage overnight 15mA draw. Why could not they fix the problem with standard ALTIMA batter? Why 15 mA draw when all modules re powered down?

the problem happened when I bought the car. It is NOT a recent issue.

Hey there, if the battery wouldn't start even after a drive then the battery likely was bad and had a bad cell so it was not charging. This is very common! Had one the other day on a rogue and the battery was just 2 years old. Actually made the car STALL and wouldn't restart.

15ma current off draw is fine. That's within acceptable limits.

What exactly is your question?

ohh and to explain the last question.

The current off draw of 15ma is the battery back up power to the ECM, BCM, Radio presets, unified meter.

If there was not small draw from those items you would lose all you saved trip meters, radio stations, module memory.
