Batteries Stand-alone solar electric systems use lead acid batteries to store power for cloudy weather or for nighttime. Lead acid batteries can be made to withstand deep-cycling, that is discharging them to near-empty. They do not have any *memory* like NiCds do. They can even be re-invigorated if they are abused, for example, sulfation can be reversed, more water can be added, etc. If charged properly, good lead acid batteries will last for years. The larger deep cycle batteries last 10 to 15 years. (source: http://www.etmsolar.com/basics.htm )
