Festool HighPower Battery BP 18 Li 5,0 HP-ASI 2026

HighPower Battery Set BP 18 Li 5,0 HP-ASI: All-rounder: Powerful and versatile – suitable for all machines and applications.

The 5.0 Ah Li-HighPower battery set is a true all-rounder and suitable for all machines and applications. Thanks to innovative Li-HighPower battery technology, it now offers even more power: especially for our latest generation of saws and the cordless planer HLC 82, it offers up to 50% more power compared to a 5.0 Ah standard battery.
The powerful all-rounder supports work with outstanding performance and long runtime. This is ensured by the excellent combination of the battery set and our brushless EC-TEC motors. It also impresses when charging: thanks to AIRSTREAM technology, active cooling takes place before and during charging with the AIRSTREAM fast charger SCA 16, and the device is ready for use again extremely quickly.
If the battery set has Bluetooth®, it automatically starts the connected mobile dust extractor when the power tool is switched on – and provides precise information about the charging status and operating data, such as temperature or charging cycles, via the Festool app. And of course, it is comprehensively covered by Festool's service.
