I think the PbSO4 forms crystals rather then spongy deposits that can re-disolve on the lead plates and reduces the effective surface are of the plate. Lower effective area means higher internal resistance.
With any lead acid battery the number of charge/dischage cycles depends on how far you discharge them. You can optimize your system for either low size weight and cost or for "greatest number of amp hours removed from the battery over it's lifetime" The two goals are in conflict. Almost all the methods people use to "fix" a LA battery that no longer holds a charge don't work so well. If the battery did not have a long enough service lit it's best to buy a replacement that is rated with more amp hours. Don't buy a gel cell unless yu really do need to use it's ability to operate in all orientations, upside down and such. If it will stay upright a sealed, flooded battery will give better performance. > > > Anyone know why Gel Cell batteries go HI-Z if discharged below a certain > level? > Also is there a way to rejuvenate a "dead" one? -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
