Update: I replaced the batteries today, and indeed, several of the old
ones (mostly in the first pack) were split and some had popped a couple of
their "sealed" tops.

I left for several hours and came back to the house stinking like burning
rubber.  The new batteries are apparently melting the terminal rubber
insulation.  I had to throw it back into bypass mode and unplug that pack
(the only one with new batteries!)

Any ideas to the cause? The status screens looked ok. ("no bad batteries"
again)
Tip: Except where a newly supplied battery is faulty, replace all or none - across all your packs connected to the same UPS.
