Last LONGER
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.

Good for the price
Works as well as B&B batteries, but don' know they will hold up after constant usage, too early to tell.

Correct Batteries but turns out that the problem is my drill (not working even with new batteries).
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.

fits as the original
As of this writing, I haven't used them enough to rate anything but the fast delivery. They seem to charge and fit as the original's did.
