This Garmin AC Adapter provides alternative power to the Garmin Astro DC-40 Dog Tracking Collar instead of running off the collar's internal batteries.
Garmin AC adapter is for use with the Garmin DC-40 Dog Tracking Collar only.
Charging a depleted Astro DC-40 battery takes 4 1/2 hours. The blue LED flashes when the collar is charging. Your unit is fully charged when the blue LED is solid, and you'll be ready to get out in the field again.
We also offer Garmin Lithium Ion batteries for use with the Garmin DC-40 (sold separately). Purchase a spare battery so that you'll always have a fully charged DC-40 Dog Tracking Collar.
