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

Good price. Works like factory.

### ⭐⭐⭐⭐⭐ Last LONGER
*by D***Y on July 21, 2024*

The battery last LONGER compare to the other Black & Decker battery. For some reason it takes longer to charge. The reason may be I use my hedger until the battery end or like FINE WINE it takes TIME. I'm NOT complaining AT ALL I LOVE the batteries its MORE powerful than my initial B & D batteries. Furthermore, the first model of B&D batteries take longer to charge as well. My rating on the ion batteries 6 star's still. I like to hera from others about their experience. Thank you B&D and Amazon Prime too.
