Rebuilding Dead Tools
December 7, 2016
I have purchased many of these NiMh batteries in the past to replace the NiCds in my dead battery powered tools. In this purchase I bought 8 cells to replace the NiCds in an almost new Black and Decker Dust Buster. NiCds always go bad, but are still used in new consumer items. With some difficulty I was able to remove the dead cells and reassemble the new cells in the dust buster. NiCd batteries run down when not in use. NiMh cells hold the charge a long time, so they should not be kept on the charger. I recommend these cells for jobs like this if you have reasonable skill with soldering and small tools.
  • Battery Junction has been very easy to deal with. Prices are good and delivery has been prompt.

Great replacement batteries for my WaterPik Cordless Water Flosser, Model WP-360
July 30, 2016
The batteries worked well with my WaterPik Cordless Water Flosser, Model WP-360. I had actually found the instructions on replacing the batteries on a youtube video. The procedure was very easy. The batteries seem to keep a charge longer than the originals, but that would be expected.
  • The replacement batteries came with the solder tabs attached to the batteries.

Perfect for rebuilding hard to find battery packs
July 13, 2016
Another 5 years has gone by and it was time to rebuild my HP-97 calculator's battery pack. It's not even worth searching for a replacement when for less than $15, I can rebuild my own with higher capacity than the original batteries.

Good Buy

Seems like good quality for the price. I made up a couple of 4.8 volt battery packs and they took a full charge from the charger. Will see how they hold up in the long run.
