Company Profile
Product Overview
Designed exclusively for the iPhone 15 Pro Max, our Sealed Enclosure Lithium Battery redefines reliability and durability in mobile power solutions. Boasting a precise 3.869V voltage and a true 4422mAh high-capacity cell, this replacement battery is engineered to match the original device’s power specifications while elevating performance through its advanced sealed enclosure technology.
Unlike generic batteries that compromise on protection, our product features a hermetically sealed casing—forged with high-grade aluminum alloy and precision-molded polymer materials—that creates an impenetrable barrier against dust, moisture, accidental spills, and internal leakage.
This sealed design not only safeguards the battery’s internal components from environmental damage but also enhances thermal stability, preventing overheating during high-load usage such as 4K video recording, graphic-intensive gaming, or extended video conferencing.
Every unit undergoes rigorous third-party testing to validate its capacity, voltage consistency, and sealing integrity, ensuring it meets or exceeds industry standards (CE, RoHS, UN38.3, FCC certified). The battery’s 1:1 OEM-compatible dimensions and connector design guarantee a seamless, tool-friendly installation—no modifications to your iPhone 15 Pro Max are required, and it integrates flawlessly with iOS’s power management system, supporting features like optimized charging and battery health tracking.
