[QUOTE="_CY_, post: 3972990, member: 7629"] been running AGM batteries salvaged from commercial UPS which will replace all AGM at set timed intervals. commercial resellers run em out all the time. purchased 5x at $50 each, been running two in my 12v cummins for 8+ years, swapping out on occasion to rotate or when I need a strong battery else where. please note I'm pretty careful maintaining charge levels. AGM reaches full charge about 12.85v vs about 12.55 for wet pb .. its critical charger used for AGM not exceed 14.4v or it could damage AGM. but wet pb accepts 15v+ with no problems. with few exceptions all 12v charging systems run about 13.8v to 14.4v what kills lead acid batteries is letting charge levels go down too far.
