The Garmin Catalyst 2 battery lasts up to 45 minutes and takes about 2.5 hours to charge over USB-C. For a full track day, run it on vehicle power with the included 13 ft (4 m) vehicle power cable and dual-port vehicle power adapter.
The box also includes a 5 ft (1.5 m) charging/data cable and a low-profile magnetic mount, so the unit stays powered and in place through every session. Browse all Garmin Catalyst accessories.
