Festool 579271, BP 18 TBX 8 ASI 8.0Ah Battery

When the job demands more, the TBX 8 delivers. 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 runtime, 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 connectivity adds even more control. Automatically start a paired Dust Extractor when the tool powers on, or use the Festool app to monitor charge level, temperature, and usage data. From heavy-duty cutting to continuous extraction, the TBX 8 keeps you working longer—with the power to get through the toughest tasks.
