Gell batteries will recover from full discharge, but the led acid ones most likely are goners. You can do a load test after you charge it overnight. If you don=B9t have a load tester, go to Sears and they will do it. Damaged battery after charge will show 12-13V, but if you put load on it, it will collapse below 10V.

Hi Guys.  
 
Here is a question for those on the list that know about the vagaries of wh= y batteries drain down to 10.2 volts in about 10 days time.  This 12v, = 24AH, sealed lead acid battery was new in Oct 03.  It has held a charge= (except when I leave a switch on) until now.  I can not find any closed= circuits except for the little electronic compass that draws little.
Thanks for any help!
