I guess I'll contact the guys who I bought the battery from and see what can be done. If they won't take it back, I'll likely keep it. It's way too easy to knock the power cord out of the 100 series, and I think I'd rather have at least a little bit of a backup in case I do bump it (which will likely happen a lot as I plan on doing a lot of writing on this little 180c in the future). Worth $30 for that? Probably not. I'd say what I got was worth maybe $5 at the max. Still, I can at least take what John said to heart--I took one for the team here. Hopefully nobody else will be snookered into buying one of these duds.

I'll keep you folks updated on whether or not I can get a suitable battery in exchange.
