Aux Battery replacement the easy way... pull the fender flare

[SparkleTooth]

seems like the way they all should have been made.

I'm going to be replacing both of my batteries soon and I am having a hard time finding an aftermarket higher quality Aux. Battery. Any suggestions?
Can you tell me what the part number is on your Aux battery, I am having trouble finding 3.0 specific battery specs.

i've never actually seen mine; haven't had the need yet.

my fav local dealers underground website says its:
BAAUA200AA
Mopar Bay Area Website listing

i believe it's a Group Size 401, and 20 seconds with Google says that Super Start and Die Hard (amongst others) make an AGM for it, but perhaps you could ask @calemasters for confirmation; looks like he's been in there on his.

Thanks, I did check out Diehard prior to posting and found an AGM, but didnt seem to be a fit for mine. The 3.0 seems to be very particular in this department, and I want to make sure I get it right. I do think I will go with an Odyssey Main battery....I wish they made an Aux battery as well. Seriously this stop/start nonsense truly makes me wax nostalgic for my old 4.0 Inline six, wind up windows, and one battery that last for years.

For my 3.0 diesel, the Diehard AGM aux battery Grp size 14 (which I wanted) was too large. Diehard did not have a Grp size 12 AGM aux battery. Therefore, I installed a Duralast Platinum AGM battery (Grp size 12) with a 3 year warranty.

For the main battery, I installed Odyssey Performance 94R-850 AGM Grp Size 94 which fit perfectly. It's hard to find a better battery than Odyssey. The Enersys/Odyssey manufacturing plant is 1 mile from my home, so the choice was easy.

my turn to change batteries. i changed the main one today and dealership says i need to gm change auxiliary at same time. problem is, not very mechanically inclined and have zero interest in ripping off the fender flare (i won’t be able to get it back on…just how i am wired).

long story short dealership says $550 to replace auxiliary battery and then reprogram everything but i don’t read anyone programming anything after changing the auxiliary battery.

or am i missing something.

Have a mechanically inclined buddy help you No reprogramming needed other then any radio settings, etc.

i am going to try this tomorrow. i need an extension for a ratchet, and of course the battery.

no fender pull, going from the top.

ps: whoever designed this should be shot

I URGE you, DO NOT do it from the top ESPECIALLY if you're not mechanically inclined. It is VERY easy to bend a pin when putting the power distribution (fuse) box back together and then you'll really want to shoot someone This should help you with the fender route:

Bypass the Aux battery.

i am going to pull the fender when i get 10 clips in.

ALWAYS go thru the top!

 

[Pdiehm]

update on this. was all set to pull the fender but no clips. then i was going to go through the top but didn’t trust myself. saw on youtube someone took out 2 screws left fender on and peeled back liner. did that but really really tight and not knowing what i am doing, working upside down is t a great idea.

found a place to install it for $175 total. all over it.

Don’t do it. The fender route is a lot safer and a lot easier.

not doing it myself at all. wonder why it wasn’t placed under the main battery….
