Yes, the Garmin Alpha battery used in both Alpha 100 and Alpha 200 models is also compatible with the Alpha 300 handheld. In fact, this is the same battery included with all Alpha 300 units. For optimal performance, it’s recommended to use the most recent year model batteries in the Alpha 300, while the Alpha 100 works only with older batteries manufactured before 2020. You can easily identify the battery’s year of production by checking the lower right-hand corner on the back of the battery.
