Festool Tabless Battery BP 18 TBX 8 ASI

Pre-order now for shipment starting September 23, 2026.

With 8.0 Ah capacity and tabless cell technology, this is the most powerful and longest-running battery in the Festool system, built for high-demand tools like saws and dust extractors. Tabless technology reduces internal resistance, delivering more usable power with less heat. That means longer run time, consistent performance under load, and faster charging.

With AIRSTREAM technology, the battery is actively cooled during charging, so it’s ready to go again in as little as 25 minutes with the SCA 16 Rapid Charger. Bluetooth automatically start a paired dust extractor when the tool powers on, or use the Festool app to monitor charge level, temperature and usage data.
