Review: So far great quality - Bought these after my 5 or 6 year old factory Black and Decker batteries for my weed whip wouldn't hold a charge anymore. I've used these new ones a handful of times and they allow me to walk all over my few acre yard taking care of edges and borders again. I don't continuously use them, rather walk from tree to tree or cleaning up around various flower beds and buildings. They charge perfectly fine with the original black and decker charger that came with my weed whip. Glad to be able to take care of everything in my yard again. Good buy for the price from what i'm seeing at this time.
Review: Great price - Love the new batteries. They do take quite a while to charge. Like that I got two for a great price.

### ⭐⭐⭐⭐ Decent replacement
*by G***R on July 9, 2025*

Why did you pick this product vs others?: After about six or seven years of use, the original batteries for my Black & Decker weed whacker finally got to the point that they wouldn't hold a charge for very long. I purchased these and am happy to report they fit both the tool and the charger, however, one of the batteries isn't holding a good charge. It lasts about as long as one of the better original batteries after fully charged. I haven't tried the other one yet, but I noticed even the two original batteries held charges differently, so I'm happy enough.
