We've been having some issues with batteries this season as well. We use the Battery Beak, check our batteries with the CBA before and after every regional, and try to conserve battery life as much as possible. What I've found, in doing this, is that batteries that are old, and especially have been dropped in any way, are noticeably less reliable, with less charging capacity and amp hours. We get around this by using brand-new (2013+) batteries, and removing them from the roster if they get dropped, until we can test them to find out if they're usable.
<EDIT>
After reading the OP, we charge all our batteries at around 3~3.5 amps. I'll have my captain check me on this, but I do know that we don't like to charge on the maximum amp. </EDIT>
