Chassis Battery Replacement

[Jabber Jaw]

I am going to replace the chassis battery in my 2019 Ford F-53 chassis, 2020 Newmar Canyon Star "3710".
But I have a question.
I plan to replace the chassis battery with an AGM battery.
Will this cause any potential issues or conflict with the charging system?? When at home, it is always plugged into its' 50 amp receptacle.

Thanks.

My hunch is it’s already an AGM. What is in there now?

Regular lead-acid battery from Ford.
There has always been a slight parasitic drain, but battery always stayed charged. About two weeks ago, it suddenly showed 7.24 volts on the energy management system. I charged it with my charger for about an hour, started it up, and let it run about 35-40 minutes. Showed 13.75-14.25, while running. After cutting engine off, & waiting about 30 minutes, it showed 12.97 (house batteries showed 13.05)
Left it connected, as usual, went to Virginia for Christmas, got back yesterday, checked, & it showed 11.87 (about 3:00pm), this morning, it shows 11.74. I'm thinking maybe a weak cell!
But, if I go to the trouble to take it out to have tested, may as well buy & install a new one, & be done with it.
The "AGM" seems to be the way to go, as long as there's no charging conflict when driving, shore power, or generator.

This seems to be battery month....just replaced the Terrain battery, before the holidays, get back, & the battery back-up for the RV garage door is beeping, & needs replacement! Ordered last night!
Guess I ought to go ahead and replace the Colorado battery, and they will all be one!
Well, until time to replace "house batteries"!!
