As a part of the 80V series of Kobalt outdoor power equipment, the battery is interchangeable with the 80V mower, blower, and string trimmer. The 2.0 Ah battery fully charges at 30 minutes, which I found impressive for 144 watt hour battery. Being battery powered, there are the benefits of less noise, no fumes, and no mixing of gas and oil compared to a gas chainsaw.
