I have a '95 4x4 tacoma. What is the best, most powerful battery anyone has used in their Tacoma? It seems the Tacoma has the pos and neg terminals different from most other batteries. The Sears platinum group 35 has 740 cca and 100 reserve minutes for what that is worth, for 189.00. It looks like a longer battery would fit, with more reserve power, but most other sizes have the polarity reversed. the cables could be lengthened but that may or may not be that easy or maybe neccesary. I have an ARB fridge and plan on winch, lights, etc in the future. My current Interstate battery wont keep the fridge on for a day without the fridge turning off due to low voltage. I live in Texas where the temp where the fridge is is 120 during the day.
I just put an Optima D-31M Blue Top in my truck. Biggest Baddest out there that I could shoe horn in. You just need to fab up a couple of brackets. The specs speak for itself. This bitch is huge!!
