Overheat the battery by drawing too much current for too long and the

All these nasty effects can take place _within_ a cell, leading to the
healthy part of the cell feeding current to the damaged part, and
internal heating. Practical cells consist of many pairs of plates in
parallel, so is there any difference between plate pairs in parallel in
one jar of electrolyte and plate pairs in parallel in more than one jar
of electrolyte (assuming equal temperature, etc.)? (That's a genuine
question, BTW, I don't know the answer.)

Another interesting question is when paralleling batteries should one
(if possible) strap all equipotential points, i.e.
