I saw some older posts but I had a discussion with someone about what is the best AGM Starting battery out there (no Lithium), all sources point to the X2 31M Battery (SLI31AGMDPM X2Power BCI Group 31M 12V 100AH 1150CCA AGM Deep Cycle Marine & RV Battery).
Is anything out there better than this in Group Size 31?
