BassMunky Posted May 26, 2021 Report Posted May 26, 2021 Just replaced my alt last night took a crap on me. Thinking should I replace both my agm batteries idk if there bad or not. They where both replaced with the alt 4 years ago. When I drive my voltage read 14.4 solid while driving reg. If I come to a dead stop it will drop to 13.8. Then go back up to 14.5 back to a steady 14.4. Any help please thankyou.

If you're not losing voltage or having any problems starting the car, I wouldn't worry about changing them just yet. 2011 Chevy Silverado under construction My build log here. Check it out!

If you where getting down to dangerous levels (below 12 volts) and you weren't dropping that low before, I'd say change the AGM's. But from your description, I wouldn't worry about changing the batteries. They still seem strong 2011 Chevy Silverado under construction My build log here. Check it out!

If you're talking about it dropping to 13.8 at a dead stop, I wouldn't worry about that at all. That's only because your engine RPM's drop when you're stopped therefore your alternator output goes down a little. Completely normal. As long as it goes back up when you start driving again, nothing to worry about 2011 Chevy Silverado under construction My build log here. Check it out!
