I read somewhere that there's more $ profit in a replacement battery
than in the orignal discounted laptop.

Like all spares, really. Or consumables. Ink jet cartridges etc.

If every device used the high-tech (currently LiIon) equivalent of the
AA battery that is available at any store, your laptop battery would
cost $10.

If you say so. I was more thinking of power tools that use the normal
Sub-C cell. To replace those with *decent* ones can cost more than the
entire tool.

Back to the original question.
About 3 years ago, there was a store popping up on every other corner
to recondition your laptop/drill/radio battery. They charged about half
the price of a new pack and guaranteed some percentage of full capacity.
Those stores are ALL gone. That should tell you something about the
results.

Never had those in the UK that I knew about. It was economical to replace
mobile phone cells on a DIY basis with like for like quality, but not
things like cheap power tools. Although the performance of those could
usually be improved with better than OEM cells.
