Replacing Battery, will computer forget my tire/wheel size?

[UseThe4orce]

Replacing battery on a 2020 Gladiator.

The dealer programmed the computer with my aftermarket wheels/tire size when I purchased the Jeep.

Will that need to be redone or will it remain?
If so, Will a OBDII memory saver help with that?
Battery is not completely dead yet, its been almost 5 years in FL heat and the remote start is starting to get buggy.

Thanks Fam!!

If a Jeep dealership programmed it, it is now written into the vehicle configuration in the BCM. So it will be there after a battery disconnect interrupts power.

No

No it doesn't lose any settings. Just be careful to isolate the ends of the cables when changing the batteries so you don't blow the high current fuse array. Be sure to replace both batteries at the same time and fully charge them before installation.

ha! I didn know there were two batteries but now I understand why autozone showed multiple size batteries as being “an exact fit”.

thanks!

The Main Battery tray will accept a H6 or H7 (94R). The factory configuration determines which one it ships with. The 94R has a higher capacity, and many switch to that size when they replace the Main Battery.
