Lead Acid Starter Battery Choice (1 Viewer)

[69 Pigboy]

‘96 FZJ80. I need to replace a ten year old Diehard Platinum AGM ( back when Odyssey made them). PO managed to wedge a Group 31 in there.

I don’t need it to be deep cycle because it won’t really be used for accessories (got a lithium for that in the back). Don’t particularly want another AGM since the alternator doesn’t put out enough voltage to keep it happy. Really looking for the most CCA in a size that will fit in the space without wedging it in there (Group 24 or 27?).

Thoughts?

Had very good luck with Costco dual purpose batteries. Inexpensive and good I think. Made by Interstate (?) I think.

It lasted 10 years. I'd say it was pretty happy.

You're not wrong. AGMs usually extend the CCA range up around 1000 too....

Sounds like your setup is similar to mine in the sense that my start batt runs no aftermarket accessories.
Just a data point to +1 Interstate 27group wet batt. Running 2 up front.
And if it's worth anything, running 2 Interstate D4 AGM's out back fed by a RedArc BCDC.
OEM alternator on all of them.

I too have really enjoyed the price and quality of the interstate batteries from Costco.

afaik the charging/agm thing is bs. been using agm since 98, will never use a regular battery again.

I have a die hard platinum agm in my 40 as the main start batt, at least 10 years, been a good batt. After using lots of batts I have formed the opinion that they are random, some good, some great, some dead from day 1. I will say the blue top optima and the Sears platinum ( P2, IIRC) were the best/ repeat cycles and lasted the longest. Being low on voltage is what kills them. I have solar keeping all batts alive on all my vehicles as I got tired of starting em all every sunday.
