>Somebody (any electrical engineers listening?) may be able to give you a
more scientific explanation. But the final result is the same: batteries
can die suddenly.

It will take more than an electrical engineer. It will take a chemist,
too.
It will be helpful to know that a battery is a collection of cells (that is
why it is called a battery: a group of things connected or used together)
and a failure in any individual cell can manifest itself in a manner that
can be confusing without keeping this fact in mind. For example, a short
in a cell can make the battery look like it is a 10 volt model instead of a
12 volt. An open circuit in a cell can keep the rest of the cells from
charging and the battery will behave as though it wasn't there.
Partial shorts and opens can best be explained by a person familiar with
the chemistry involved. I am not well versed in battery chemistry. Well
not enough to explain it with any authority. Perhaps someone else on the
list knows the chemistry.
