Festool 578939 HighPower Battery Pack BP 18 Li 5,0 HP-ASI is the proven all-around workhorse of Festool’s 18-volt system, now enhanced with upgraded Li-HighPower cell technology for even stronger performance. This 5.0 Ah battery delivers up to 50% more power than a standard 5.0 Ah battery, making it especially effective with high-demand tools such as Festool’s latest generation of saws. It offers powerful cutting performance, longer runtimes, and reliable output across a wide range of applications. Engineered for balance and versatility, this battery combines strong power delivery with practical runtime, making it an ideal everyday choice for professionals who need one battery to handle nearly everything. Its optimized energy output works in perfect harmony with Festool’s brushless EC-TEC motors, helping tools run more efficiently, smoothly, and consistently under load. Charging performance is equally impressive; when paired with the AIRSTREAM SCA 16 rapid charger, the battery is actively cooled before and during charging, allowing it to recharge faster and reduce downtime on the jobsite. Integrated Bluetooth® connectivity adds smart functionality by automatically starting a paired Festool CLEANTEC dust extractor when the cordless tool is switched on. Users can also access detailed battery information such as charge level, temperature, and charge cycles through the Festool app. Powerful, reliable, and built for everyday use, this 5.0 Ah Li-HighPower battery delivers the performance professionals expect, backed by Festool Service for long-term confidence and support.
