✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Charge limit voltage: 4.35V

Extend the runtime of your iPhone 11 Pro Max with this DJ-IPH-11ProMax 4700mAh High Capacity replacement battery. The factory battery is rated at 3969mAh — this upgraded version delivers over 18% additional capacity for significantly extended daily use. The iPhone 11 Pro Max features a 6.5-inch Super Retina XDR display and A13 Bionic chip. This high-density Li-ion Polymer 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.
Why Choose the High Capacity Edition: Unlike standard replacement batteries that simply match the factory capacity, this DJ-IPH-11ProMax battery delivers 4700mAh — a substantial upgrade that translates to noticeably longer usage between charges. After years of use, the original battery capacity naturally degrades, often falling below 80% of its original rating. Common symptoms include: the phone requiring multiple charges per day, unexpected shutdowns at 15-20% battery, slower charging than when new, or the device only working when plugged into a charger. This high-capacity replacement restores and even exceeds the original performance, extending the useful life of your iPhone 11 Pro Max. The battery fully supports 18W PD fast charging — reaching approximately 50% charge in 30 minutes with a compatible USB-C PD power adapter.
Compatibility Note: Fits iPhone 11 Pro Max only. Works with all regional models — US, Japan, Europe, Hong Kong, and other regions. This battery is 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.
