Documentation says it's not user replaceable. If it gets to that point, plug in an external battery pack.
One has to ask about the average life of the battery - If the unit has to be returned to a designated repair point, then that brings about a 2 way shipping, labor and parts bill that could cause one to resort to cheap beer for the rest of the month. Battery life is generally shaped around recharges=usage, and to some degree, shelf life. Interesting as to why Garmin designed this unit around a non user repair? Tnx Whttail In MT for the info,
