This high-density Li-ion battery is built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.

⚠️ Important Safety Warning: Battery replacement should only be performed by technicians with the knowledge and experience to repair electronic devices. Improper battery replacement could result in fire, injury, data loss, or damage to the device. iPhone 11 Pro Max uses adhesive strips to secure the battery — removal requires specialized tools and technique. Professional installation is strongly recommended.
Important Notes — iOS Repair Assistant: iPhone 11 Pro Max has a sealed design with adhesive-secured battery. After installing this battery:
- iOS 18 or later: After reassembly, go to Settings → General → About → Parts & Service History, tap “Restart & Complete Repair” to run Repair Assistant. This will calibrate the battery.
- iOS 17.6 or earlier: You may receive a “Non-Genuine Part” notification and cannot access Battery Health data. The battery functions normally — this is an iOS limitation.
Compatibility Note: Fits iPhone 11 Pro Max only. Works with all regional models — US, Japan, Europe, Hong Kong, and other regions. NOT compatible with iPhone 11 or iPhone 11 Pro. The factory iPhone supports 18W or higher USB-C PD fast charging — this replacement maintains the same charging capability. Please verify your device model before purchasing.
Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity. For best lifespan, use a certified 18W or higher USB-C PD charger. If you notice swelling or overheating, stop use immediately.
