I put Duracell AGM's in my 03' recently from Batteries Plus, I wanted to get the X2 AGMs but they didn't have any in stock for group 65 (website inventory conflict). I have a new starter and cross over cables; she fires pretty fast for temps in NC.
I was able to get an X2 AGM for my 91' Accord (absolutely unnecessary amount of cranking amps, 840 iirc) and it turns over stupid fast. I wanted to be able to boost my 2500 if all else fails.
.02: I purchase batteries with a one and done mindset, I don't want to play the warranty game with cheap batteries, the lost time and inconvenience of having a dead or dying battery and getting replacements (that are good off the shelf) isn't worth it.
