Garmin Beeper Battery Pack for Alpha T20 / TT25 Dog Collar - Rechargeable Li-ion w/LED Beacon

The Garmin Beeper Battery Pack transforms your Alpha T20 or Alpha TT25 dog collar device into a full beeper-equipped tracking system, adding audible run and point alerts, a built-in LED beacon, and extended rechargeable runtime in a single integrated pack. It is the factory beeper module and dedicated power source for these Alpha-series collars, designed by Garmin to drop directly into the T20 / TT25 in place of the standard battery.

Inside the pack sits a rechargeable lithium-ion cell rated for up to 78 hours of battery life in dynamic tracking mode, so a single charge covers long days in the field and multi-dog training sessions. The pack recharges through the integrated USB interface, and the same module drives the beeper speaker to deliver 5 unique sounds across 3 selectable modes with 3 individual volume levels, letting you tune audible cues to your hunting style and cover conditions.

An integrated LED beacon on the pack adds a visible locating signal in low light, complementing the audible alerts so you can keep tabs on your dog by sound or sight. Built specifically for the Garmin Alpha T20 and Alpha TT25 dog collar devices, the pack is finished in black and installs as a direct-fit module on the collar.

Whether you are working a pointing dog through heavy grouse cover or running hounds at distance, the Garmin Beeper Battery Pack gives your Alpha T20 or TT25 the sound, light, and stamina to keep up with the hunt.
