While IO was still under the effects of the untreated epilpsy, I bought new battery drills. None of them lasted more than a year.

 
What were you doing with two drills that lasted less than one year?
Were you trying to used them to power one of your bicycles and convert
it into an eBike?  It's possible to do that, but the results are not
very good:

If it was less than 1 year, the drill was probably covered by a
warranty.  Were you able to get you money back and buy something more
appropriate?
 
Incidentally, I've been spending too much time watching YouTube videos
on repairing power tools:

If you're considering repairing the two drills you destroyed, watching
some of these videos should be useful.  However, there's one problem.
The author is in Ireland and speaks with a very thick accent.
Sub-titles (captions) are a big help.

As is usual with you, you assume things you know nothing about. Just sitting around destroyed the batteries. They need to be discharged and charged frequently to live a normal life. Doing nothing at all but sitting in the cupboard destroyed the batteries of thier own volition since actual use was infrequent.

You didn't explain how you killed the two "battery drills".  Did you
kill the drills, the batteries, or was it two drills used together as
a battery of drills?[1] 

Hint... one storage device is called a cell.  Two or more cells are
called a battery.  A cell phone has only a single LIPO cell and should
properly be called a "cell phone cell" and not a "cell phone battery".
Anyway, you're wrong (as usual) about how to manage cells and
batteries for long life.  If you have any interest in rectifying your
illusions, this is a good start.

If you're interested in batteries and as a non-engineer, I recommend
his book:
"Batteries in a Portable World: a Handbook on Rechargeable Batteries
for Non-Engineers, Third Edition"

"Historically the term "battery" referred to a cluster of cannon in
action as a group, either in a temporary field position during a
battle or at the siege of a fortress or a city."
