I reshaped the internal contacts a little to apply more spring force to the ends of the sub-C cells, and it seems to be working fine now. So add that to the list of troubleshooting steps for "skinny" 97 printouts! Still going to lube up the internals for good measure, though.

Glad you got it fixed. I would've installed a tiny heater to always keep it warm!

Oh, it definitely crossed my mind. I've got a bunch of spare 5V 1A regulators that I'm sure could be used to produce a little heat at the cost of battery life.
