Suitable for all Festool 18 V series tools and machines, the 5.0 Ah battery provides sufficient power for all applications. A convincingly powerful and versatile solution that offers high capacity and long life per charge. This is thanks to the seamless interaction between the powerful battery and the brushless EC-TEC motors. Thanks to the AIRSTREAM technology of the AIRSTREAM quick charger, the battery is actively cooled before and during charging. This means that the battery is ready for use again very quickly. The battery with Bluetooth® connection automatically starts the system vacuum cleaner connected to the tool when the battery tool is switched on - and provides the exact charging status and usage information, such as temperature or charging cycles, via the Festool app. Of course, it is also covered by the all-encompassing Festool Service warranty.
