That's a very good idea yopapamon. I am a member of a hard core science forum so I asked those guys about the idea of a small solar charger being able to keep the sulfasion from happening. i will post back when they reply. Your idea of just burning a small insignificant led or bulb sounds nice also but I think if it were really that simple batteries would come with LED's built in for that purpose and everyone would be doing it to protect their batteries.

There is desulfasion (google it) devices out there that claim they can remove all sulfasion and make the battery like new again, but they all require you plug the battery into the device for long periods of time and run off an AC circuit. These may be good to recondition an old battery to extend it's life. There are plans on the net to build these yourself too. I may look into these one some day if I can't afford LifePO4 batteries when these suckers die.
