Are all 18 v Li batteries interchangeable with certain tool products?
I have a Worx trimmer and edger that takes such a battery. I realize
they eventually will lose their power or so I was told, after so many
recharges. Out of curiosity, I checked with the company and they are
charging a ridiculous amount for the replacement. For a few dollars
more I can buy another edger of theirs, but there is absolutely
nothing wrong with the one I have. Recently, I saw an ad for a
cordless drill that comes with a 18 v Li battery selling for half the
price of what just the battery would cost with Worx. I just as soon
as buy 'another drill', just as to benefit from the battery, but I do
not know if they are interchangeable.

I've never seen any two that are interchangeable, even when the
"innards" (the Li-Ion cells) are identical. Many different brands use
the same Sanyo cells with the same part numbers -- even the Ridgid with
the lifetime warranty and the allegedly "19.2V"* Craftsman -- but the
physical configuration of the package differs from one brand to the next.

*Perhaps they show 19.2V for the first few seconds after they're removed
from the charger.

Yeah, I have a really nice 12v LIon Bosch drill ... and a 12v LIon small
Milwaukee sabre saw. The battery packs use virtually identical plastic
case parts, but are assembled in such a way (180 degrees twisted) to
make them totally incompatible. Even the polarity is reversed! When I
acquired the 2nd tool above, I was excited when I looked at the battery
.... that is until I put them side by side.
