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. "

Or you could use one of those smaller 12V lawn tractor batteries,or a
motorcycle battery,more portable.Use a longer,heavier gauge cord,maybe
salvaged from an old extension cord.
