charging my batteries.

I have a xs power D5100 agm power cell in the front and in the back I have a stinger sp1000 I usually break circuit and trickle charge them every other week. However idk if I'm using the correct settings on my charger. I using the Agm/Gel setting but should I be using the deep cycle setting instead? The options on the charger are as follows: 12v standard 12v deep cycle 12v agm/gel 6v standard (Seperate setting) 2a trickle 12a fast 30a rapid MECP Certified

Dont Ground Out!!!

AGM/gel. Deep is probably for wet cells and hence can go above 14.4V which will damage AGMs. Unused batteries should be kept on trickle (provided it is a regulated "full time" charge - not a small simple transformer type that can go above 14.4V, and trickle charge should only be ~13.2-13.6V to prevent battery discharge). And for AGMs, the lower the charge (and drain) current, the better. Same too for wets, though occasionally wets need a high current or voltage recharge for reconditioning or "maintenance". Maybe too an occasional high-current discharge.
