What kind of Battery?

[Bulldog]

I've had the conventional lead acid batteries last longer than the AGM batteries. I had an Orbital from Alaska Battery in my Bobcat and it only lasted about 3 years. I went to get another and they don't recommend the Orbital brand and were actually steering me towards a conventional battery. My Bobcat sees lots of vibration and shock so I wanted a AGM battery and I bought a red Optima from them. I've had another Orbital that has been in my red Chevy truck for 5 years now and is still running strong. If you go with Optima, I think Sam's Club has the best price in town.

For my CUCV which is a diesel and I'll be running big winches, I am planning large conventional lead acid batteries mounted in the bed. The larger batteries will have more capacity for winching and starting the diesel.
