## Customer Reviews

### ⭐⭐⭐⭐⭐ Great replacement for B&D tools.
*by D***R on October 21, 2025*

Works well in my Black&Decker tools.Seems to last longer than brand name.

### ⭐⭐⭐⭐⭐ Good deal
*by M***E on September 25, 2025*

Good price. Works like factory.

### ⭐⭐⭐⭐⭐ Correct Batteries but turns out that the problem is my drill (not working even with new batteries).
*by R***S on February 24, 2025*

The batteries were exactly as described. However, I will be returning them, not due to any product defect but because the drill that I purchased them for does not work. I wasn't sure if it was the batter or the drill. So, I no longer have a use for the batteries. Thank you.
