Festool 18V Airstream Battery w/Bluetooth, 5.0Ah (577661)

This 5.0Ah battery from Festool features Bluetooth technology that turns on your CT Dust Extractor (Bluetooth models or Bluetooth retrofitted models only) in sync with select cordless tools. When used with the SCA 8 Airstream rapid charger, charge times are much shorter, thanks to active cooling. An integrated LED displays the charge status at all times so you always know whether to bring extra batteries along.

Note: Not compatible with ETSC/DTSC/RTSC sanders or CXS/TXS cordless drills.
