  • Works as advertised
I've used this replacement battery for about six months now for edging and trimming. It's holding up well and has a longer run time than my OEM battery had when it was new. It works with both my Black & Decker chargers, although one of the chargers is finicky about charging it, sometimes throwing the red light warning, while the other one charges it 100% of the time. I'd buy it again. ... show more

  • Good quality replacement batteries
These are good quality batteries and I bought two extra for the weedeater that I purchased. I also bought an extra charger to go with these. The updated version of these chargers and batteries makes it simple and easy to recharge your batteries. Sometimes I get some pretty heavy duty grass and weeds around my house and these batteries keep my weedeater running at full speed and they last quite a while. ... show more

  • We'll buy another one to replace my spare
Works great! Lasts a long time. A lot better than the Black& Decker batteries

  • Failed and now unusable after 2 uses.
This is the first one star review I’ve ever left for an Amazon purchase. On the third use of this battery, it completely stopped functioning/delivering power to connected equipment despite all 4 status lights illuminating when charge level is checked. Also, when attempting to connect the battery to the charger, the charger now produces rapid red light flashing, indicating there is an issue charging the battery. The battery is no longer chargeable or useable. Waste of money for sure. ... show more

  • Good
Charged quickly and works well. Fits the leaf blower that I bought it for might fit other things as well, not sure, definitely worth its money.
