new battery for the 80
looking to replace the battery in the 80, and reccomendations for a big powerful battery that will still fit?

I have this one:
Lots of room.

Lots of people like the group 31s (mud folks are almost unanimous) but they are a little tougher to fit.

If I did it again, I'd probably try to stuff that guy in there:

My group 31 blue top optima fit easy but after reading reviews of the new optima's I would not go down that road again. Mine is an older made in USA battery. Its been working strong 4 years now. I guess the new ones are made in Mexico and suffer from poor quality control.

My next (2nd) will either be the Die Hard Marine group 31 or a Deka Intimidator group 31.

Thanks Guys,
I just read a ton of posts about the Group 31 Diehard, and the great experiences people have with them.. i did not realize they had so many cold cranking amps, and had such a long reserve.. the small amount of trimming on the 3 fins that was needed to shoehorn it in seems well worth it... I also found the Deka was using the same technology... so whichever of the 2 i get the better deal on will go in!!! Thanks again!

other thing to consider on the two is warranty. which one will be easier to replace on road or at home if need be? Probably the Die Hard

I picked up the DieHard Marine Battery, Platinum PM-1 - Group Size 31M. My friends mother get's a good discount on Sears stuff (worked there for over 20 years), so i had her pick it up for me. Trimmed the 3 Fins per the threads on Ih8mud, and it droppes in like a champ, real tight fit... Need to make the new bracket, and manipulate the positive wires so they extend to the new positive post...... but it is big (like 70+ lbs), 1150 CCA, and a 3 hr reserve is way cool!

reserve is the most important thing to consider. especially on newer electronic vehicles. i wouldn't go for high ccas. 450cca is factory and they work just fine in this area of the country, so i would stay in the 450 to 750. to get higher ccas, you need more plates. to get more plates to fit in a battery means thinner plates and less acid. acid keeps the battery cool and heat kills batteries. thin plates are more prone to breakage through vibration, which kills batteries.
