Better battery than the one sent with my blower!
My original battery actually didn't last as long as this one and then finally I had to keep turning off the blower and back on again to make it work and then it was only for maybe 30 seconds every time I did it. I was going to buy a new blower but decided to buy a new battery first and am so glad I did! This one works great and I will probably buy another one to have charging when this one is in use.

Perfect fit, holds the charge well
Purchased as a replacement for a 40V Black & Decker battery that came with a line trimmer. It took a charge from the B&D charger without issue, fit the line trimmer perfectly, and still showed two green lights when I was finished trimming. And the cost was less than half of the replacement B&D battery on the shelf of a local big box home improvement store. Don't know how long it will last, but it looks like a great deal right now.

Works great in place of a 36 volt battery
I bought this battery to replace my 36 volt Black & Decker weed eater battery. I was somewhat skeptical on how well it would work seeing as the voltage was different. I was pleasantly surprised how well it worked & how long it lasted. I will likely purchase a second one, as we live on a wooded half acre lot.

Defective device
Ordered and received two new batteries. One will charge; the other will not. Not eligible for return or replacement. By the time we paid shipping $35 down the drain on a fixed income!

Perfect for my Black and Decker 40V string trimmer
Love the B&D 40 Volt trimmer. The existing battery was beginning to fade so I purchased this one. So far through about 6 weeks of use it is working great and certainly lasts longer than the original. Highly recommended.
