Note for Technicians: Replacing an Apple Watch Series 10 battery requires heating tools to soften display water-resistance seals, micro-spudgers to safely lift delicate flex ribbon connections, and new display adhesive tape upon reassembly. Always perform 2–3 full charge and discharge cycles after installation to properly calibrate the new battery controller.
