The Festool Tabless Battery BP 18 TBX 8 ASI (579271) delivers maximum power and extended runtime for high-demand 18V cordless power tools in the Festool system. Engineered with advanced tabless cell technology, this 8.0 Ah lithium-ion battery pack significantly reduces internal electrical resistance and heat buildup under continuous tool load. This lowered operating temperature allows tools to maintain steady speed and torque during heavy-duty applications such as continuous track saw cutting, timber framing, and high-volume dust extraction.

Built for jobsite efficiency, the BP 18 TBX 8 ASI features AIRSTREAM active cooling compatibility, allowing the battery to be actively cooled before and during charging to reach full readiness in as little as 25 minutes when paired with the Festool SCA 16 rapid charger. Integrated Bluetooth technology enables automatic wireless communication with paired Festool CLEANTEC dust extractors, automatically starting dust extraction when the connected cordless tool is powered on. Users can also connect to the Festool app to view real-time battery status, including charge level, temperature, and usage data. A soft-touch non-marring base protects delicate work surfaces from scratches while preventing the battery from slipping on sloped materials.
