What should be the charging voltage range without load and with load??
Range total 13.8 to 14.2 max
14.2 under no load with a large alternator for a dual battery setup or dual ac setup, above mostly in diesels
14 to 14.1 in a relatively small car alternator, non hybrids
13.8 with factory load, mostly in all setups
13.4 with large non factory sound system with normal load
13.2 and below alternator most likely faulty or loose belt
But mind u newer cars have alternator clutches that disengage and engage alternator with load and battery status so this is not fully reliable, also ISG units in Suzukis do the opposite and go to 11.9 in load as it propels the engine and goes to 13.8 to 14.2 whilst idling. Hybrids and electric cars run at a much lower voltage and narrow range and rarely touches 13v 12.5 to 12.8 mostly
well mine was reading around 13.7 ish (if im not mistaken) with load (lights and AC) my garage said charging system is fine. But one battery shop said battery is good but charging system is performing low under load. So looking at ur answers, my charging system seems to be working fine.
Battery is a exide and 2.8 years OLD now
