As soon as I received these I gave them a workout on my B%26D weed trimmer. I was able to trim my entire backyard on one of the batteries, and that's a lot! I'll test the other one next time I mow. These seem to be reliable, long running powerful batteries to have around as extras for a really good price! I appreciate that!

Yes needed to replace Black%26Decker battery

These are worth the wait. The cost is very affordable and came delivered without exception. So far they are the best deal. Running my power tools now.

Good buy

They work great so far. I've been using the same black and decker weedwhacker for almost 25 years now.
