Bball, you need to match the A-hr rating and same battery chemistry if doing the direct register method. If you up the A-hr rating substantially, you need to "code" for that. I haven't done this but have read on here a fair bit. I lucked out and got a new battery replacement from the dealer including registering for free. I say "free" as you damn well know i paid for the cost in the car itself. I had made a spreadsheet of different battery options as i was thinking i would have to pay for it and didn't want to do the wrong thing.
The dealer changed my battery group number from 94R up to the larger group 49 (euro designation is H8. 94R is analogous to group H7). Here is the spreadsheet but be careful in its use. I think I came away thinking I would get the Orielly Auto one as it is made by east Penn (not on the spreadsheet). I did go back to Advance auto and look at their normal lead acid one (made by Johnson controls) in the H8 size and thought the sticker said 92 A-hr. My OEM battery was 90 A-hr and i believe that is close enough for a match that would only require the normal register then.
Wow, it says invalid file. It won't allow an excel spreadsheet. sheet man. If you want to PM me your personal email, i will send the spreadsheet to you. Us Texans need to help one another.
