<DIV><FONT face=Arial size=2>The only battery giving me a problem is the lead
acid Marine 'deep discharge' battery used for field charging
of the lipos. It has lost about 70% of it's capacity in seven
months.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It provided six 12min flts when new and was
purchased from Academy Surplus for $40. It has provided a total of maybe 80
flights ( 30 cycles ??? ). The problem is likely due to my maintenance
( lack thereof ). I left the battery in a partial discharge state sometmes
for weeks. </FONT><FONT face=Arial size=2>You can find maintenance needs on
Google at agmbatteries, courtesy Earl Haury.</FONT></DIV>
