The Makita 18-Volt X2 LXT Hedge Trimmer (model XHU04Z, tool only) is powered by two 18-Volt LXT batteries (36-Volt), so you get 36-Volt power and run time for corded and gas-powered demands, without leaving the 18-Volt LXT platform. Batteries and charger are sold separately. It's part of Makita's expanding 18-Volt Lithium-Ion series, the world's largest cordless tool line-up powered by 18-Volt Lithium-Ion slide-style battery. Makita 18-Volt Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. For improved tool performance and extended battery life, Makita created Star Protection Computer Controls. Star Protection is communication technology that allows the Star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18-Volt LXT and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside.
