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 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 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.

Rated 1 out of 5 by from Name needs to be clarified Got the item and according to name it is a double pack because in every other situation 2x is a two pack except this one the battery in this case is twice as big as a normal battery
