Work with low fatigue: At less than 600 grams, 20 % lighter and 50 % more compact than a 5.0 Ah standard battery pack. Extremely durable: the high-current-resistant cells ensure this. Full power: Li-HighPower cell technology ensures power even in demanding applications. Practical: LED display for quick indication of remaining capacity. Safe: all-round frame made of soft grip material to protect and securely support the machine on sloping surfaces. Convenient: Bluetooth enables automatic starting of the CLEANTEC suction mobile when the cordless tool is switched on (assuming use of a Bluetooth-compatible suction mobile). Smart enhanced: In combination with the Bluetooth function of the battery pack, the Festool WorkApp enables clever additional functions, such as a detailed display of the charge status and other operating data, e.g. temperature or charging cycles. To quickly and easily identify the battery with the lowest charge level, you can flash the LED display directly on the battery pack. Software updates are also possible: install the latest version to work with the latest functions of the tools at any time. For carefree everyday use: Of course, the battery packs are also fully covered by Festool Service. The Li-HighPower Compact battery pack enables fatigue-free working thanks to a weight of less than 600 grams. This makes it 20% lighter and 50% more compact than a 5.0 Ah standard battery pack. It only saves on weight, but not on power. Thanks to the Li-HighPower cell technology, it is powerful enough for any application (for extremely energy-intensive applications and when using AGC 18, HKC 18 and the TSC 55 K, we recommend the Li-HighPower battery pack with 8.0 Ah). Equipped with Bluetooth, it automatically starts a paired suction mobile when the cordless tool is switched on - and offers detailed information in combination with the Festool Work App
