The 18V X2 LXT® Chain Saw (model XCU02Z) is powered by two 18V LXT® batteries (36V), so you get 36V power and run time for corded and gas-powered demands, without leaving the 18V LXT® platform. Batteries and charger are sold separately.
It’s part of Makita’s expanding 18V Lithium-Ion series, the world’s largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery. Makita 18V Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger.
