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 Extra life battery is, as it says A bit more challenging to fit on my alligator saw, once it is there, I can work for longer. Just what I need. Glad to have the extra time with this battery!

Rated 5 out of 5 by from Lasts Longer I bought this high capacity battery last month and have used it lightly on my 20V B&D drill. I bought this to mainly use it for my grass trimmer and leaf blower which are all 20V B&D series as I needed an extra battery to power both tools. This high capacity battery is bigger and heavier than the standard one, but it will be enough to do my yard work.

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 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.
