Ok I’ve read 100 times the batteries in the late model Challenger is a AGM ! Well correct me if I’m wrong but my 19 Redeye has a conventional lead acid battery.😳 BA7821F2-FF6A-4E52-ABA9-54FECCD2FCE9.jpeg

My OEM battery from 2019 Charger Hellcat = same

Looks like lead acid to me. It sucked and had issues with warm starts so was replaced with this

I'm not convinced that the battery is the main culprit. Could be an issue that is more pronounced with a poor battery. After battery replacement things improved. No incidences of failure to start. Hot starts were better but still a little slower. So it solved my concern well enough but I still suspect there is more to the story. The Odyssey definitely made a difference.

yes, the Hellcat batteries are just the old fashioned flooded type battery. Not AGM --

I think the dealer actually told me but I pulled it out and it’s definitely not AGM but my Ford truck has AGM go figure 1589397671399.png

Interesting to hear you have a warm start issue, I've never heard of that.

One thing I did notice when I got this car was how easily/effortlessly turned over when it was warm. Really soft. Very different than my 2012 SRT8 Challenger or 2015 Scat Pack. Granted those were 392s, this is my first 6.2

Not that I've ever had a warm start type of issue though....Good luck getting to the bottom of your problem!

I thought it was an AGM as well.

If I think of it, I'll check my MY16 tomorrow

That same myth is popular with Ram pickup batteries, too.
If there are no removable tops (maintenance free), the battery somehow becomes an AGM type.
