The compact one: Full power with low weight. With tabless cell technology.

The powerful TBX 4 battery with tabless technology is your ideal partner for powerful applications - with low weight and good handling at the same time. The tabless cells make it possible: less heat development, longer runtimes and faster charging times. Thanks to AIRSTREAM technology, the battery pack with the AIRSTREAM SCA 16 quick charger is actively cooled before and during the charging process and is ready for use again extremely quickly. The optimised energy flow of the tabless batteries gives you that extra portion of power and ensures a longer service life for your battery pack. Equipped with Bluetooth®, it automatically starts a paired vacuum cleaner when the cordless tool is switched on - and, in combination with The Festool app, provides detailed information on the charge level, temperature or charge cycles. And, of course, it is fully covered by the Festool Service 3-year warranty.

Fatigue-free working: 4.0 Ah for full power with a weight of only 600g.
Full power: tabless cell technology delivers maximum power even for demanding applications.
Long-lasting: The low heat generation of the tabless cells extends the service life of the batteries.
Hot or cold: Tabless batteries are reliably ready for use even in extreme temperatures.
Shorter charging cycles: The batteries can be charged directly after use due to their low heat generation.
Charged at lightning speed: Ready for use again in 25 minutes thanks to the AIRSTREAM SCA 16 quick charger. This is made possible by active cooling during the charging process.
Practical: The LED display shows the battery pack's charge level anytime.
Sure thing: Round frame made from soft-touch material to protect and securely support the machine on sloping surfaces.
Convenient: Bluetooth® enables the CLEANTEC vacuum cleaner to start automatically when the cordless tool is switched on (provided a Bluetooth®-enabled vacuum cleaner is used).
Smart extended: The Festool app, in combination with the Bluetooth® function of the battery pack, enables clever additional functions, such as the detailed display of the charge status and other operating data such as temperature or charge cycles.
For stress-free work: The battery packs are, of course, completely covered with Festool Service.
