Actually, the Triton can charge through a diode. It can't discharge

Well, if there's no diode, or a fuse didn't blow, then he almost
certainly reverse charged his pack. Exactly how much depends on how
full the batteries were when he started, and how long the charger was
on ...
The batteries were probably damaged at least somewhat, but it may not
be enough to worry about (mostly the damage would manifest as reduced
capacity.) I'd strongly suggest at least running them through a
cycler a few times and make sure they're still OK. If the capacity is
down more than 10 or 20% from the original capacity -- replace them.
Some people are down on NiMH cells for receiver packs, as they don't
stand up to abuse as well, and have higher internal resistances, and
there is truth to all that, but for transmitter packs they're perfect.
And even if you pay full retail Wal-Mart price, 8 2000+ mAh NiMH AA
cells will only cost about $20 -- cheap insurance, and you'll probably
get a pack that will last all day. (Assuming you can make your own
packs, of course.)
