Good replacement for LBXR2520 battery
Works with our Black & Decker LST522 string trimmer and charger unit.

Great price
Love the new batteries. They do take quite a while to charge. Like that I got two for a great price.

Tight fit on the charger
Seem to be working well. The only issue I encountered was that the new replacement batteries didn't fit very well with the original B&D charger. It appeared to be the new batteries were just a bit too wide, but with a little bit of pressure, I got them on. Not as difficult to attach them to the weed eater. Batteries had a nice, strong charge, and worked well as replacemnets.

Does not charge!
I thought the battery was not as all the hype. I been having them about a year , they don't even take a charge. I even purchased a biswaye charger. Both the B&D battery flash red and the Biswaye battery flash red on the charger.

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.
