Battery is taking a lot of charge since it got cold out. I don’t know how old it is except that it was installed when this truck was over seas. What yall say? Replace it?

Nope run it till it dies. That meter wanders all over the place as it charges, based on electrical load.

if you have my luck the dam thing will just die when it's freezing raining and windy on a Sunday evening when everything just closed, if you do not know how old it is I would be safe rather than sorry. Costco has decent prices on the interstate agm

Should be a round sticker on the side of the battery somewhere with a born on date on it.

The adaptive charging on these 900's has the voltage meter all over the place as stated by CaptainA . Its difficult to figure out if you have a bad battery on these models. Check your battery cables at the battery and the ground to the frame.

I've never seen a voltmeter on these go that high quite honestly.

I routinely register over 14 volts.
