i don't have an answer for you, but i run wet cell deep cycle batts in my boat and they get regularly disscharged the most i ever get out of them is 2 years i run the same in my jeep cherokee with very seldom disscharged and get atleast 5 years i only used agm batts in my boat once they died in the first year they were optima and got replaced with wet cells again i don't know if it was a fluke or if agm don't deep cycle like wet cells all that said i want to know too because i am thinking powermaster for my explorer

resting volt is what matters the most so if your resting volts are about the same you will be fine even if they are not the same you will be ok but when you park your lowest volt batts will try to pull the voltage of the other bateries down to its voltage. not dead but down to the lowest voltage batt . so you can mix any ma batt you want as long as the voltage matches. this is because in car audio we conect them in parralell. if we used them in series like in rc car usage the voltage can varry but the ma must be the same or when being disscharged if the ma varries too much, the batt with the lowest ma will run out before the other batts and then actualy have its charge reversed<verry bad for its life span> then when charged the low batt wont fully charge then when discharged again it runs out even sooner and reverses even harder doing even more damage. batts in series are only as strong as there weakest link . this came out pretty convoluted <long night at work> if you need me to put it into english i will try

do you sell brackets to hang this as a second alt on a 2000 explorer xlt v6
