Apple Watch Series 8 45mm Battery Replacement Service

We carry batteries for the Apple Watch Series 8 45mm and most replacements are completed within 30 to 60 minutes. After the replacement we confirm battery health is displaying correctly, verify charging is working as expected, and run through the full device before handing it back.

The original water resistance seal of your Apple Watch Series 8 45mm is broken during the battery replacement process. We apply new adhesive sealing during the repair but this may not fully restore the original IP rating of the device. We recommend avoiding water-related activities including swimming and showering after the replacement as a precaution.

Our technicians are trained in Apple device repairs and use quality parts matched to your Apple Watch Series 8 45mm. Our Apple Watch battery replacement page has everything you need to know before coming in.

Signs Your Apple Watch Series 8 45mm Battery Needs Replacing

• Battery draining faster than usual: If the watch is running out of charge well before the end of the day despite normal use, battery capacity has degraded and needs replacing.
• Unexpected shutdowns with battery percentage still showing: If the watch shuts down on its own while still showing remaining battery percentage, the battery can no longer deliver consistent power.
• Watch not turning on despite charging: If the watch shows no response when placed on the charger, the battery may have fully degraded. A free diagnostic will confirm whether the battery or charging system is the cause.
• Overheating during charging or normal use: Excessive heat during charging or while wearing the watch indicates a battery that is failing internally and needs to be replaced promptly.
• Charging takes significantly longer than before: If the watch takes noticeably longer to reach a full charge, the battery is near the end of its usable life.
