⚠️ Expert Fitting Recommended
Watch repairs involve working with microscopic screws and delicate screen cables. Opening the watch compromises water resistance. We recommend professional fitting at our Brisbane shop.
❓ Battery Tech FAQs
How do I calibrate the new battery?
For best results, charge the battery to 100% and continue charging for 2 more hours. Then, use your watch until it shuts down. Finally, charge it back to 100% without interruption.
Will this fix my watch not turning on?
If your watch is over 2 years old and doesn't hold a charge or has a swollen screen, a new battery usually fixes it. Ensure your charger is working correctly before replacing.
Is this battery safe for my Apple Watch?
Absolutely. Our batteries include PTC protection and advanced PCB controls. They meet all original standards for temperature and short-circuit protection.
