Mine (circa April 2013) just started to bulge this week. It sits in a ceramic bowl now (in case of fire/explosion) until I can replace the battery. I ordered a backup battery on eBay a while back, but didn't install it because it was slightly too large. I'm going to install it now and mount it in a slightly bigger case - just to get me through until I can get a new one ordered.
Come to think of it, I may just order a really big battery and mount the PCC into a much larger box.
