In worst case scenario, you can connect the original battery connectors to
hot-wired, new leads and run off a standard 12v auto lead-acid battery.
I've done this with 2 portable electric tools (drill and skillsaw).
Guaranteed to run most of the day before needing a recharge, but a bit hefty
to lug around at the job site. better than buying overpriced nicads, and
avoids tossing away a perfectly good DC-powered tool. A good 12v lead-acid
will run a small 18v motor without any noticeable drop in power.

Ryobi 18 volt batteries are $49.00 for two at HD. Why rbuild them at
that
price.


The rebuilt from Primecell are better than the original Ryobi. Comes
back
to the cost/benefit ratio. Not long ago the Ryobi were twice that price
making a rebuild a better bargain.

I have replaced cells in a battery with the old slow recharge systems (14
hour recharge). However, the fast charge systems now in general use seem
to
need cells of very uniform characteristics. Replacing individual cells
may
not work too well.
