Core Product Advantages
The battery protection board is equipped with Ti chip, paired with high-density cell structure to raise the endurance of iPhone 11 Pro Max, sustaining stable power output under high-load scenarios such as video recording and mobile gaming.
The upgraded multi-layer protection circuit board can prevent risks of overcharging, deep over-discharge, overcurrent, short circuit and overheating.
Reliable cycle performance: after more than 500 full charge-discharge cycles, the whole battery maintains battery health above 80%, showing better long-term stability than ordinary generic replacement batteries.
Compatible with PD 20W wired fast charging. The built-in temperature sensing module reduces abnormal heat accumulation during continuous charging.
Good adaptability to all iOS versions. The battery runs smoothly after system updates and will not trigger abnormal battery status display after installation.
Molded according to the original phone housing dimension. The precise outline enables simple installation without risks of squeezing the phone body or lifting the screen.
Every finished battery will go through continuous discharge aging test and internal resistance screening to ensure consistent batch performance for bulk orders.
Production & Quality Control Process
Raw materials including cell cores, circuit boards, adhesive tapes and insulating films must pass IQC incoming inspection before entering production lines. All assembly operations are completed in a dust-free workshop via automatic welding and insulation encapsulation to form complete battery packs. Finished products will undergo multiple tests covering voltage consistency, internal resistance, continuous discharge performance and safety protection function. Qualified batteries are vacuum-sealed for shipment. Custom stickers, logo printing and personalized packaging services are supported.
OEM & ODM Cooperation
We accept large-volume stock orders and customized development projects. Available services include cell performance tuning, circuit board modification with Ti chip solution, brand logo printing and custom packaging design. Sample lead time for standard models is 2-4 weeks, while full customized projects take 6-8 weeks. Cooperation procedure：Requirement confirmation → Engineering assessment → Sample production → Compatibility verification → Mass production → Delivery. Our partners include private-label brand owners, cross-border importers, wholesale traders and nationwide repair service networks.
