Recommended Posts

Posted

Okay so my voltage has been 14.8 while driving (14.3-14.7) when im slamming it) ever since i got the car. Yesterday i get in my car, start er up, and i see it only goes to 14.5.... Even when reving the engine, it never went over 14.5... Now, i got in it this morning and it still says 14.5 while driving? (Not playing music)

Can someone give me a little insight about whats going on?

You probably need to charge the batteries with an external battery charger. Also the temperature can affect the voltage. This happens all the time in my vehicle. If I throw it on the charger for a few hours the problem is solved. If the problem consists there is a possibility that a cell may be going bad your battery.

Just replaced battery less than a year ago. Its not bad i know that for a fact. Its always sits at 12.6 when the car is off, never drops. Like i said usually when im driving its usually 14.8 the temperarure here in KY went from 38 on saturday, to 62 on sunday... Could that effect it?

That will definitely effect it. As your car heats up after driving for a long while youll notice the voltage start to drop too while driving.

Really? How is that gonna effect system wise? What will my voltage drop look like? Would the big 3 help the initial drop from 14.8 to 14.5? If not, is there any way to get it back up there?
