NCC battery for iPhone 12 Pro Max 3687mAh with option to be assigned as USED

The Diagnosable battery for iPhone is a modern alternative that completely eliminates complex processes such as soldering, transferring the BMS, spot welding or battery programming. Using a plug and play mechanism, you simply insert the new battery into the casing and carry out a short assignment procedure in diagnostic mode. The device's operating system will accept the component as an authentic or used part, so no notifications about an unidentified component will appear on the screen.

Battery pairing instructions for the phone Prerequisites: iOS 18 or later software and a stable internet connection.

Quick configuration procedure in seven steps: 1. After physically installing the battery in the phone, the system will detect it automatically. 2. Open the Settings menu, select the General tab, then About, and go to the Parts and Repair History section. 3. Tap the notification regarding the new battery and confirm your choice by selecting Continue. 4. Connect to a Wi-Fi network and follow the instructions that appear on the screen. 5. Confirm acceptance of the terms, which will cause the system to treat the cell as original. 6. Restart the device once the entire process is complete. 7. Check the battery health in the Settings menu by selecting Battery, then Battery Health.

If the standard configuration method fails: - Switch the phone off completely. - Press and hold both volume buttons at the same time, i.e. the volume up and volume down buttons. - Connect the charger cable, without releasing pressure on the volume buttons. - Release the buttons when the manufacturer's logo appears on the display. - Follow the diagnostic prompts shown on the screen.

Important operating notes The component offered maintains full compatibility with system versions from iOS 18 to iOS 26, provided stable, official software releases supplied by Apple are installed. Pairing stability is not guaranteed when using beta test software. Any changes introduced in future system updates may affect the component recognition process, for which the distributor and the cell manufacturer bear no responsibility and do not guarantee that the pairing function will work on those systems.
