Garmin Extended Battery Pack for Alpha T20/TT25 Dog Collars - Black

The Garmin Extended Battery Pack is a genuine Garmin OEM replacement battery built specifically for the Alpha T20 and Alpha TT25 GPS dog tracking and training collars. This user-replaceable Lithium Ion pack is designed as a direct swap for the standard battery, giving hunters, houndsmen, and dog handlers a simple way to dramatically extend the in-field runtime of their existing collars without purchasing a whole new collar.

Compared to the standard battery, the extended pack is rated for up to 136 hours of operation on a dynamic update rate, allowing for multi-day trips and long training sessions without recharging. Lithium Ion chemistry delivers dependable cold- and warm-weather performance, and a full recharge takes about 5 hours using the dedicated charging clip included with the battery.

Finished in black to match the Alpha T20 and TT25 collars, this is a true Garmin factory accessory that simply drops into the original battery compartment. It is intended for users who already own one of these collars and need longer run time between charges in the field.
