Customers find these batteries to be of good quality, with one mentioning they work well in older B&D dust busters.

Good packs with fast delivery
Robert—September 12, 2025
Quality 18630 cells with prime delivery. I've used these to build packs, replace cells in packs, and for the "usual" use of 18650's in various devices. They work well, hold a charge as well as any other pack, and cost about the same as 18650 store without the long wait times. That said, these are NOT high amperage batteries and should not be used for high/fast draw applications (electric vehicle packs, RC power packs, unregulated draw devices) Read more

Great batteries for an older B&D dust buster
obwan—December 24, 2025
I needed 5 batteries to replace in a Black and Decker dust buster where B&D didn't even offer a replacement battery pack. So, I researched on how to replace them on You Tube. Figured I could do it, so I bought these batteries. The only issue I had is that I needed to buy a spot welder to rebuild the pack. It was well worth buying both the spot welder and the batteries. I would buy these batteries again. The dust buster has never worked this good since we bought it 5 years ago. Read more

Been using these batteries for 34 days now work very well long lasting work great in my vape mod they discharge pretty evenly within 4-5% of each other recharge the same would recommend these for vape mods since that’s all I’ve used them for.. will repurchase again when needed. Read more

Good at this price point
Murat Belge—December 11, 2025
After fully charging, a discharge test from 4.2 to 2.8 reveals 2,947mAh. Lower than rated by about 10% but still better than most at this price point. Read more

Good, long lasting multiple-recharge batteries.
pstaffor—August 13, 2025
I bought these to supply electricity to a large outdoor wall sconce that I retrofitted to use 3V LED lamps. I used 2 of these batteries in parallel to supply 4 1 watt lamps with 3V over a period of 12 hours of darkness. A single solar panel can charge two of these batteries sufficiently to run all night, even in winter. These have been very good so far. Read more
