Treatment of Patient A (Black & Decker DustBuster) seems to have been successful. It has two series NiCad. One battery was zapped with 15V from a cap, the other had 15VDC put to it until it started to charge. I left it on its charger overnight and seems to be perfectly healthy this morning. Its caregiver tells me it was used from new for just a couple of weeks about 3 years ago and then tossed in the drawer. Both cells were 0.00 and unchargeable before yesterday Send in the next one please nurse.......... -- http://www.piclist.com#nomail Going offline?
