Go outside to your car with a multimeter and measure the voltage across the battery.

With the car not running it could range anywhere between 11.2-12.4v
With the car running and on idle it will range somewhere between 13.2-13.6v
With the car running at approximately 1500-2000RPM it will sit between 14-14.4v.


At no point SHOULD IT exceed that. The battery manufacturer might say that, but that's for a QUICK charge (Which will not properly charge the battery), not a SUSTAINED input. Tyre's have "Maximum 60PSI" written on the side of them. Do you put 60PSI into them?


I had a car with the alternator charging the battery at 14.8v. It took 4 months for it to kill things. The battery would no longer hold voltage. Fuses and globes were blowing. I had electrical gremlins everywhere. THE SYSTEM IS NOT DESIGNED TO HAVE 15V GOING INTO IT. That's why I said the alternator would have had the current output changed, if anything were changed.

you need a new multimeter then, because 14.8volts won't blow globes or kill batteries.

It will eventually. It's not going to kill it as quickly as 18v will, but it'll kill them.

14.8volts is on the high side, but its not going to kill anything.
