My best good-bad battery B3 developed a tumor. After its first run, I left it unhooked (not shorted out, nor loaded), for some 6-8 hours.

I went downstairs to try the next phase and noticed that the most-positive corner of the battery had bulged quite badly and the glued-down vent cover had lifted.

It looks like it still works - the motor started right away, and adding a 12v bulb across it caused the motor to speed up.
