My phv1800 18 volt hand vac's battery seems to be running down. is there any way to revive it? if not; can i purchase a new battery to replace it? thank you!
If you are handy with a soldering iron, and don't mind spending a few hours building a new battery pack using 1.2 volt "sub c" cells, you can disassemble the PHV1800, and rebuild the pack yourself. I just did it tonight, and the vacuum works like new.
However, I'm not going to do this again. The PHV1800 doesn't use a single battery pack, but 2 packs that have to be assembled with very little room for error. You can purchase a combination battery pack/motor assembly for $75 (US currency, price currect as of 10/2011), unscrew the screws that hold the vacuum together, and replace the battery/motor unit as one.
