What battery are you other diesel guys running up here? Mine just crapped the bed and I need a new one (or two).

 

Nevermind.

 

Interstate MTP 65 X 2 always replace them in pairs the bad one will take out the marginal one "don't get cheap on me 'click' "

 

2 yellow top optimas

 

Thanks guys. After doing my research and finding that only 3-4 manufacturers actually make all the batteries out there... I went to Costco and the got a couple of replacements with a "no questions asked" 3 year full replacement warranty. Optimas would be nice but that isn't in my budget right now.

 

i understand! you know costco sell a knock off a a optima right..
