The most powerful and durable battery in the Festool range: suitable for any machine and any application - the Li-HighPower battery ensures maximum uptime and performance (60% longer life compared to a standard 5.0 Ah battery), even for heavy-duty work. As with all Festool batteries, it is optimally tailored to Festool's brushless EC-TEC motors - this enables maximum efficiency and capacity per battery charge. This power package is also convincing when charging: thanks to the AIRSTREAM technology of the SCA 16 AIRSTREAM quick charger, the battery is actively cooled before and during charging, so that the battery can be charged extremely quickly. The battery with Bluetooth® connectivity automatically starts the system vacuum cleaner connected to the tool when the cordless tool is switched on - and communicates the exact charging status and operating data, such as temperature or charging cycles, via the Festool app. Of course, it is also covered by the comprehensive Festool Service warranty.
