If you decide it's a battery or charging issue, remember that AGM (absorbed 
glass mat) recombinant batteries, are pretty sensitive to charge voltage level 
and temperature.  It's best to use a temp-controlled voltage regulator with 
them so you don't burn them up.  As they get hotter the internal resistance 
changes and requires that the battery be charged at a lower voltage level. 
 The B&C regulator has this capability (along with crowbar overvoltage 
protection) and is a great choice if you're using today's hi-tech batteries. 
 Check your charging specs carefully to make sure you're not overcharging. 
 Just a FWIW.
