i was wondering if DieHard Batteries r any good? The platinum seem to have good specs. and warranties.

What do ya know?

for what?

to start a car, as a second cell? for your tractor?

All around starting / xtra power in general .

They're good batteries, but pretty much every name brand battery on the market is good. Don't buy into the hype of "car audio" specific batteries. Just buy a good name brand unit that fits your budget.

The Platinum series is made by Odyssey and from what I read when doing my research, they are excellent batteries. I have had a group 34 in my '01 Wrangler for 2 years now and has seen it share with loooong uphill winch pulls and has loved every second of it.
