  • Good replacements
I ordered these because they're more powerful than most others like them.

  • Good Value, work well
I purchased these at the beginning of the summer to supplement my batter for my Black & Decker edger. So far they seem to hold a charge as long as my B&D batteries. I can't yet speak to longevity as I've only had them a few months. Definitely a good value.

  • Edging power restored
Battery life is great. Batteries charged up normally and installed in my black and decker weed eater. Ran approximately continuously 15 min before depletion of charge.

  • Fit ans function.
Fits well, charges fast and at a reasonable price, just don't know how many charges or time these batteries last.

  • Female connector on battery became bent after a couple uses (repaired it myself)
One of the battery connections that the blades on the vacuum slide into became bent on the battery. I disassembled the battery and manually straightened out the blade and now it's working again but it's a tight fit getting it to engage on the vacuum. This does NOT seem to be a common occurrence that was my experience. ... show more

Good for grass trimmer.

  • Waste of money
3ah batteries, not 4ah. Initially held charge about as long as a 1.5ah battery. After 8 months, they indicate fully charged, but last about 20 seconds. Garbage. Don't waste your money
