Battery voltage 15.1v
When I drove the SS home for the first time, I was looking through the DIC and found battery voltage. The voltage was 15.0v. I watched the voltage drop to 14.4v on the way home. I know the normal 12v charging system will charge at 14.4v. I wanted to know why the voltage was above normal. I started in the trunk with the battery. To my surprise I found an AGM battery and not flooded lead acid. AGM batteries like to charge at higher rates and I'm glad the voltage regular setup in the SS is right for AGM batteries.
AGM batteries do not vent acid gases or leak like others:smile:
They have a longer usable life cycle with higher power output.
One draw back I know of with AGM batteries, DO NOT let them go flat!
A dead AGM will not come back to 100% It can be recharged and be somewhat usable but not at full potential.

!5 is fine. The charging is computer controlled algorithm (no regulator like the old days) to max charge without damaging battery and takes into account temperature, load etc. Sometimes it will drop to 12.5 for a while them bounce around a bit.When I drove the SS home for the first time, I was looking through the DIC and found battery voltage.

My Yukon and Enclave (lead acid) have gauges so you can watch it and for the most part it will stay at about 14.5. Remember the high loads new cars have with all the computers, heated stuff, cooling fans, electric rack, high watt radios and the list goes on.
I never thought to look behind the access at the battery in the one on my dealer's floor. AGM is good because you can put a maintainer on it in the garage and not worry about hydrogen or acid vapors.
Does it have a vent tube ???
Just went out and looked. There is a vent tube.
Battery info:
CCA 700
RC 130
AH 70
There is a fuse panel in the battery compartment too.

Nice time for a picture of the odometer!
3hrs, I was waiting for the first comment.
It just hit me like a big heavy thing!3hrs, I was waiting for the first comment.
Hehehe, you're car must be evil, in more ways than one.3hrs, I was waiting for the first comment.
