Installation Notes
Moderate difficulty. No soldering required. The battery connects by a plug on its short flex that seats into the board once the old cell is removed. Opening the tracker requires heat, pry tools, and patience, and the case is resealed with adhesive afterward. The repair kit option includes the disassembly tools and glue you need for the job. This is a repair part best suited to a careful, experienced hand.
