Really delighted with what will now be known as “The Big Battery”. Plenty power equals more cuts without charging saving time and money.

Solid battery, have been using in combination with DeWalt 1007, even after some heavy use I still haven't used one bar. Definitely has enough power to run for extended time.

Big battery but not much bigger than the 6.0AH. Used with brushless strimmer/brush cutter and lasted a good couple of hours. These batteries are the ones that fit where 18V batteries won’t.
