About this product

Festool Airstream 18V 8Ah Lithium Ion Power Tool Battery Pack with Fuel Indicator

Festool’s Li-HighPower Battery Pack is engineered for serious performance—built to deliver maximum power and durability, even on the toughest jobs. Offering up to 60% more runtime than standard 5.0Ah batteries, it’s the perfect match for demanding tasks that require consistent, long-lasting energy. Designed to work seamlessly with Festool’s EC-TEC brushless motors, this battery ensures efficient output and optimal performance every time you power up. With AIRSTREAM cooling technology, it charges faster and runs cooler—so downtime stays short and productivity stays high. Integrated Bluetooth® capability automatically syncs with your connected Festool dust extractor when the tool starts, and with the Festool Work app, you can monitor charge level, temperature, and battery health in real time. Backed by Festool Service, this battery is built to work as hard as you do—job after job.
