Exide Edge AGM batteries .
These are similar to Optima batteries but significantly cheaper .
I paid $ 140 each for two from BiMart for group 78 for my 2002 gmc diesel pickup .
I rarely pitch a brand of pickup truck . I some times pitch a brand of tire .
But there are only two domestic makers of AGM batteries . Johnson Controls ( Optima ) and Exide ( EDGE ) .
If you do not know about AGM batteries then you can do some research .
They do not leak . They will stand a deeper discharge cycle . They recharge faster . And they last longer .
The Exide Edge may have a 4 year full replacement warranty if i recall correctly .
AGM batteries are just plain better .
The trick is finding the place that sells the EDGE , cheap .
In Oregon that is BiMart .
