The Festool Tabless Battery 4.0Ah 18V is a compact, high-performance lithium-ion battery designed to deliver extra power, longer runtime and faster charging for Festool 18V cordless tools. Featuring advanced tabless cell technology, it generates less heat during use, helping maintain consistent power output for demanding applications while extending overall battery service life. Despite its impressive power, the battery weighs only 600g, making it ideal for users who need a lightweight solution for prolonged work with reduced fatigue.
This Festool 4.0Ah 18V battery pack combines Bluetooth® connectivity with AIRSTREAM charging technology for greater convenience and productivity. The battery’s Bluetooth® capability means you can turn your cordless tool on, and a paired CLEANTEC vacuum cleaner (Bluetooth®-enabled) will start automatically. When paired with The Festool app, users can access detailed operating data including charge level, temperature and charge cycles, plus the integrated LED charge indicator on the battery provides an instant view of remaining power. Used with the Festool AIRSTREAM SCA 16 quick charger, the battery can be actively cooled before and during charging and returned to use in as little as 25 minutes.
