On the 2 ah battery it will run approximately 30 minutes. With the extended run 4 ah battery you will get about 60 minutes.

Run time will depend on the load the saw is under. Example, cutting hard woods vs. soft and the size of limbs/trees you are cutting. I have the battery that came with the unit and it performed much better than I anticipated. The larger battery has 2X the capacity so you could expect approximately 2X the work between charges.
