Default How reliable are recon. batts?

I've seen ads and auction listings for "reconditioned batteries" for
laptop and notebook computers.

If you've tried a rejuvinated battery, please post your experience,
bad or good. Also, any recommendations, as to whether to buy a "new",
"used", "refurbished", or "reconditioned" batteries.

Doesn`t it mean that it`s a reclaimed battery case with new rechargable
cells fitted inside? Not rejuvenated as in cycled many times to restore
some of the original capacity.

It depends on the cells they use, often times a remanufactured battery will
use newer higher capacity cells than the original and will be better than
new.

The common way would be just to re-cell it. But if a new one is still
available it *should* be cheaper due to lower mass production costs.

The primary reason for proprietary batteries is to keep the PROFIT up.
I read somewhere that there's more $ profit in a replacement battery
than in the orignal discounted laptop.

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.

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.

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

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.

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.

WELL, almost all LiIon packs use the normal 18650 cell.
Problem is that they're packaged in proprietary plastic and you
need a tiny spot welder to replace 'em. Not to mention that you
have a very difficult time buying individual cells.
If the consumer could go down to the corner drugstore and pick up
sub-C cells for their power tool or 18650s for their laptop, they would
be much cheaper. If consumers weren't so stupid and could follow simple
directions, we wouldn't need multiple layers of stupid-proof safety
protection...or nearly as many lawyers.
Technology ain't the problem...it's all about the Benjamins.

I'm not sure about 18650, but tagged sub-C which can be soldered by
anyone are readily available in the UK. But not from a 'drugstore' etc as
they're not a standard size like AA etc.

directions, we wouldn't need multiple layers of stupid-proof safety

Heh heh - could be.
