Rated 5 out of 5 by from 4.0 amp hr Battery This is by far, much better than the 1.5 that came with the trimmer and blower. We can do our whole lawn and clean up with one charge.

Rated 4 out of 5 by from Lithium battery Works well, but seems to need recharging fast than I expected. I bought a quick charger to solve the problem.

Rated 1 out of 5 by from 2X is only 1. I bought this 2X and had it shipped to the store. When I went to pick it up, it was only 1 battery. The girl at the counter called cause she, like me thought it should be 2 batteries!!! So I left in disgust, NOT picking it, now I'll have to wait months for Walmart to refund my money!!! If I'd of known about B&D practices, I'd of bought a different brand!!!! And when I go to buy a battery powered lawnmower it will NOT be a Black & Decker brand!!!!

Rated 5 out of 5 by from Excellent battery to extend cordless tool use! The battery was used to extend the use of a cordless weed eater and blower. The weed eater could deplete a standard battery in 15-20 minutes. I was able to operate the weed eater for 35-40 minutes and the larger battery still had power left. This is a great way to make your tools more useful.
