90Ah+ replacement battery?

dwells · 02-17-2014, 10:15 AM

Hey everyone, I'm looking to replace the battery but I'd like to replace it with one that meets or exceeds the 90Ah capacity of the OEM battery. I'm having trouble finding anything that fits and has more than 80Ah. Any suggestions?

EDIT: Stumbled across this battery: http://shop.advanceautoparts.com/web...gold_2130012-p. Description states that it has a reserve capacity of 160 minutes, and I've read that you can estimate AH with RC/2+16, which would mean that this battery is ~96Ah. I'm thinking this is the closest match for OEM then?

I saw the same conversion formula - but I'm not sure how accurate it is. I just purchased a DieHard AGM Gold with a 170 minute reserve capacity and it is 92ah. That battery is probably pretty close to 90.
