Optima red tops are the best, I've never heard anything bad about them.
It's strange. It had done the same thing like about 3 weeks ago, but those have been the only two times I've seen it do that. I had also been thinking of getting a high output alternator, so I guess I'll have to test the battery and alt. and see which one is going to get replaced first. Any cons to high output alts.? Recomended brand or sites to buy from would be helpful too.
Can someone tell me the difference between the optima red tops and yellow tops?
