I'm thinking that the safety vents are triggering, which is why I asked that list of questions. I'd like to find out why they're triggering.

I guess we can also add:

--Did you go over the bumps or have a hard landing of any form shortly before noticing the acid?
--Is the battery upright or sideways (or upside-down) in the robot? Noting the answers posted already, I'd guess upright, but it never hurts to make sure.
--What's the charge rate that you use when charging?
