You have dual use trolling batteries...size 24...so you have about 75 amp hours of capacity for deep cycle use before you hit 50% depleted and need to recharge.
I think they are using a variety of mfr's ...but all seem to be dual 24grp dual purpose wet cells...I think the black unlabled ones are Chinese.
These are fine for plug in use in campgrounds...but will deplete quickly while boondocking and offer far fewer cycles than a true pair of deep cycle batteries. 10.87" W x 6.75" D x 9.87" H
