We have a sweeper. It uses a pack of sub-C NiCads -- six of them. The original ones didn't have much capacity -- 1200 mAh -- needed to be charged before each use, and eventually couldn't make it through a single round of sweeping before dying. It was order another sweeper at $129+, or replace the batteries. The Tenergy cells, once I soldered the tabs in the correct sequence and turned them into a battery pack, can do two or three rounds of sweeping at full power before needing a charge, and will hold a charge between uses. They're great, the price is terrific. Couldn't be happier.

I bought these to build a pack for a Shark carpet sweeper. I replaced 1300mah cells with these 2200 mah cells for much better run time. I was able to use my Tenergy charger on the 1.8A setting for a quick charge, still staying within safe specs. I felt more,comfortable buying a reputable brand cell for what I would pay for generic stuff on eBay. Delivery was quick and I would not hesitate to buy here again. The sweeper is up and running.

As a DIY'er, and someone who isn't a throw away person, this small battery purchase repaired a small electronic appliance that although not too expensive to purchase new, this simple battery swap took care of the trick. Let's see how long its activity use and longevity are between charges and discharges.

Batteries replaced those in a 30 year old Craftsman power screwdriver. I ordered the tabbed version and soldered them in place without problems. The new batteries charge up with the tool's charger without issue.

The 7 batteries I bought arrived on time and were exactly as ordered. Have installed and are working awesome! If more needed, I will order again.
