[QUOTE="condor22, post: 250528, member: 1932"] Yup in the GT digging, but here's my take. Yes the charger will see one big battery, BUT - Here's a scenario for you, re an 80AH and a 120AH joined to be charged in parallel. Assume the 80AH is at 95% charged i.e only 4AH used. It's charging requirement would be in the last stages of Absorption mode i.e. bugger all Amps then, Assume the 120AH is at 50% capacity so 60AH used it's requirement is in Bulk Charge mode, i.e. pumping in high Amps. A smart charger sees the overall, decides the bank needs Bulk mode and you are thumping the hell out of the 80AH which is close to only wanting Float mode. (the figures are, as above - total 200AH of which 65AH used = 32.5% used = BULK charge till about 90% charged) My opinion, depending on the difference in state of charge of either battery, if definitively known, it's not a place I personally would want to stand too close to. FACT [list=*] [*]You can charge multiple batteries of the same age type and capacity if they are in parallel when discharged and remain so when charged.[/*] [*]I would definitely NOT recommend charging multiple batteries that are discharged separately or of different capacity. a. It could be dangerous, b. The batteries will suffer. [/*] [/list] [/QUOTE]
