Festool HighPower Battery BP 18 Li 4,0 HPC-ASI

Weighing less than 600 grams, the Li-HighPower Compact battery pack allows for fatigue-free work thanks to its extremely low weight. It is 20% lighter and 50% more compact than the 5.0 Ah standard pack. The weight saving is not reflected in power. Because thanks to Li-HighPower cell technology, it is powerful enough for any application (for extremely power-hungry applications such as the AGC 18, HKC 18 and TSC 55 K, we recommend using the 8.0 Ah Li-HighPower battery pack).

Fatigue-free work: weighing even less than 600 grams, it is 20% lighter and 50% more compact than the standard 5.0 Ah battery.
Extremely long service life: high-current resistant batteries ensure this.
Full power: Li-HighPower cell technology ensures performance even under high load.
Practical: LED indicator for quick display of remaining capacity.
Safe: surrounding frame made of soft softgrip material to protect the device and provide stable support on inclined surfaces.
Convenient: When the cordless tool is switched on, the CLEANTEC mobile dust extractor can also be automatically started via Bluetooth® (requires the use of a mobile dust extractor equipped with Bluetooth®).
Smart extension: Festool's WorkApp allows you to use smart additional functions in conjunction with the battery's Bluetooth® function, such as detailed display of charging status and other operating data, e.g. temperature or charging cycles. To quickly and easily identify when the battery charge level is low, the battery's LED indicator can be made to flash. Software can also be updated: install the latest version to use the latest tool functions at all times.
Worry-free work: of course, the batteries are also fully protected with Festool Service.
Bluetooth® allows the CLEANTEC mobile dust extractor to start automatically when the cordless tool is switched on (requires the use of a mobile dust extractor with Bluetooth®).
