Charging batteries simultaneously with both solar and wind

oups.com: You can sort of fix crystallized batteries by over charging them to 16.8 volts and then beading off the excess charge. That melts most of the crystallization that happens. There is also some acid that you can buy to add to your cells that prolongs the life of batteries but I a big believer in changing batteries about every 2 years. Call it cost of ownership and live with it because it is better and safer for not that much money. All a disaster waiting to happen. Adding acid to electrolyte to "rejuvenate" dead cells is SUICIDE! The lead was eaten away from the plates and crystallized into the bottom of the battery, in the space provided for it. You come along and add acid, eating holes in already weakened plates, possibly creating a shorting hazard so the battery explodes. You have to see a boat whos battery has exploded to realize what damage that does. Please don't add acid to a dead cell, please? Going to sea with crap batteries is stupid! Batteries are cheap unless you suck up to some idiotic gauze batteries for $600 by some slick salesman in boat shoes. Golf cart batteries are throwaway consumables at $89 a pop. Use them. They work great for years, and when something doesn't start to look right, TOSS THEM to the battery recycler pile and BUY NEW ONES from a BATTERY SHOP, not a boat store! I like your idea of the 2-year swap, but cheap golf cart batteries will last much longer if one takes care of them properly.... When you zap a battery with 16.8V at really high current, the good cells boil like hell, possibly warping a plate and causing an explosion. NEVER do this crazy crap! You are NOT going to "save" a dead cell...its acid is used up, its plates are eaten away, its full of lead sulphate crystals...buy a NEW ONE. |
