Charge when you are not in a hurry because it takes almost 3 hours to fully charge.
Lots of power.

Nice for the Price
Fits nice to my Black and Decker tool , I have used it for some time now ( 2-3 months ) it has been holding the charge good too.

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.
