Extremely powerful: 8.0 Ah for enormous endurance and power delivery in applications with the highest current demands. Full power: Tabless cell technology delivers maximum power even in demanding applications. Durable: The low heat generation of the Tabless cells extends the lifespan of the batteries. Hot or cold: Tabless batteries are reliably ready for use even in extreme temperatures. Shorter charging cycles: The batteries can be recharged immediately after use due to their low heat generation. Charged in a flash: Thanks to the AIRSTREAM fast charger SCA 16, they are ready for use again in just 25 minutes. This is made possible by active cooling during the charging process. Convenient: An LED display shows the current charge level of the battery pack at any time. Safe: A surrounding frame made of soft soft-grip material protects and securely supports the machine on sloped surfaces. Comfortable: Bluetooth enables automatic starting of the CLEANTEC vacuum when the battery tool is turned on (provided a Bluetooth-capable vacuum is used). Smart expansion: The Festool app, in combination with the Bluetooth function of the battery pack, offers clever additional features, such as detailed display of the charge level and other operating data like temperature or charging cycles. For worry-free everyday use: Naturally, the battery packs are fully covered by the Festool service. The strongest and most durable battery pack in the Festool portfolio: No matter which machine, no matter which application – the TBX 8 with Tabless technology ensures maximum performance and endurance even in heavy-duty applications. The Tabless cells make it possible: lower heat generation, longer runtimes, and faster charging times. Thanks to AIRSTREAM technology, the battery pack is actively cooled with the AIRSTREAM fast charger SCA 16 before and during the charging process, making it extremely quick to be ready for use again.
