Since I have this issue I have been concerned. My battery voltage when driving on highway stays at 12.5 -12.6. I have read that it should be 13.5 to 14. I went to auto zone and they checked starter battery and alternator. Everything passed but the new battery only has an 81% charge. I think I have a weak alternator. My car does have an LSA Supercharger that I added last year. Anybody have any thoughts.

A fully charged battery should be at 12.6V. Your vehicles gauge tells you that you are only getting battery info. A good alternator should be reading 14.1 to 15v no matter what road you're driving on. Basically saying that with your vehicle off with no load your battery should be around 12.2 - 12.6V Running, it should read in the 14's. If you have a multimeter, set it to volts and put the red lead on the battery lead nut on the back of the alternator and the black lead on the case of the alternator or any ground. If its under 13.0 volts replace the alternator. A good reading would be in the 14's. |

We have adaptive charging so you’ll only see it charge under load (like at night) otherwise, you won’t see it charging all the time.
I run a trickle charger as there are loads (factory) that can drain a battery over time. The only way to know for sure is to have a draw test performed using a test light or volt meter. -Don

During the day I see 12.6 and not jumping. At night I see it move.
Not saying it can't be the alt but, try driving at night to see if the load 'excites' the charging first. Then do a draw test and then, verify all grounds... After that, may be alt... I also trickle charge the battery first to ensure a fully charged battery. My new battery took 3 days to fully charge... -Don

I also still have the original battery at 36,000+ miles. I store it in winter and have not always been diligent about the tender, so I think the battery was drained once or twice during the winter and I had to jump it. It seems to charge fine and is still going strong.
I am planning to only use OEM parts in this car, unless there is a universally accepted, better alternative. I have a lot of confidence on the information you all share here. Thanks! :-)

Ok. Is it working or not.?
I put the battery on a 1.5 amp slow charge for several hours. Then attached my digital meter. Checked battery first. It showed 12.95. Then did the parasitic test and showed 00. Now alternator check. I started car with lights radio door open everything on and it showed 14.4 to 14.8, the car gauge also matched. Finally I went for a ride battery voltage showed 14.5 to 14.6 the entire ride. So all I did was charge the battery for a few hours and now everything seems correct. The resting battery car off was always 12.3 before all this and after my drive it was 12.9. A fully charged battery is 12.6 is it not? Can this car over charge? I am going to just keep an eye on it.

A fully charged battery will be ~13.2V.
