Tenergy 2200mAh Sub C NiCd Battery for Power Tools, 1.2V Flat Top Rechargeable Sub-C Cell Batteries with Tabs, 60 Pack

The media could not be loaded. Fit was perfect and a great value compared to battery stores nearby. So far the quality is great. The batteries in the video are the old ones that I needed to replace. The new ones worked amazing and fit just in place. The tabs worked like the originals and I was able to tape down the tabs I didn’t use so they weren’t in the way. So far so good!

I had several 18v DeWalt battery packs where the batteries wouldn't hold a charge anymore. I used these batteries to replace the old ones and found that the tools work better than ever and seem to hold a charge longer. Frankly, folding the tabs to the right configuration can be a chore (and they have sharp edges) so I switched to the same battery without the tabs and picked up some nickel solder tabs (Amazon or Ebay) to make assembly much cleaner and easier. I now use this method instead of the tabbed batteries. Either way, the batteries work great and I plan to use them in the future.To add further information that may be helpful: I have had success with the following process to solder the nickel solder tabs to the untabbed batteries. First, roughen up the terminals (I used a Dremel grinder) to get a fresh surface with a little bit of "tooth". Use flux - you can get a lifetime supply at Radio Shack or an electronics store (rosin core solder didn't work as well. Brush the flux on the terminal, then solder the solder tab in place. Quick and easy with the right materials. I also use rubber bands to hold groups of batteries together for soldering. Work carefully and your battery pack will be better than new with substantial savings.

Good batteries. Good deal. I used them to restore function to a Dustbuster which not only has been restored to full power but now has 3 times the run time. The charging circuit is made for Nicads with a lower amp hour setting so it will take longer to charge but it will still give the same run time per charge hour. It will just continue to add run time after that untill it is full (three times as much).PROS:Decent quality batteries.Right size to replace many factory batteries.Pre-soldered lugs mean no soldering directly to batteries in most cases and thus no heat damage to battery.They can be charged by the original charger with some restrictions.More run time than NicadsCONS:When using original chargers made for Nicads you need to be careful not to leave it on the charge sor long periods of time, weeks is not good in some models.The pre soldered tabs both point in the same direction which does not suit all setups. Mine needed 90 degree tabs. It was easy to cut the bottom tab and solder to the stub.

I didn't know what I was doing. I learned a lot. Important to realize that these babies are shipped fully charged. My work table has an aluminum strip around the edge. NiCd batteries soldered in series react poorly when slid over the aluminum edge!Tenergy regards the vinyl shrink-wrap cover as an advantage over the typical cardstock used by OE manufacturers. And it's very photogenic! But when a clod like me accidentally arcs the tabs with the edge of a table (or the soldering iron... Jeezuzz! Who knew that big copper tip coated with solder would conduct electricity, really?), the vinyl cover produces a genie out of a puff of smoke, leaving even more exposed surface to arc. I quickly understood the advantage of the tiny TP tubes. When you touch them with a soldering iron, they just get a darker brown spot - same as your skin does. So, I learned real quick to slide the TP tubes off the old cells and onto the new ones.All that learned, a little practice with tinning technique, and I was able to rebuild a couple battery packs for my 14.4V Blue Point 3/8" impact driver. I had to create a couple clearance notches in the plastic case for my first effort, which didn't quite fit back in the housing, but my second one was much better and looks factory. Time will tell how these last, but my driver works nicely and nothing burst into flames when I put them on the charger. Around here, lack of explosion/flames is the litmus test for success.

I had a HF original tool battery power pack. Couldn't get a replacement no where, so I opened it up and searched for the batteries, and found these batteries. I spot welded them as the old worn out pack and so far these batteries are outstanding. I used 50% of the battery power. I plug in the pack on it charger and I was surprised that the pack was recharge in 11 minutes. So I'm satisfied for this purchase.
