The Haisic Advantage at a Glance

Installation & Compatibility Guide

When it comes to your Apple iPhone 13 Pro Max battery repair, safety and precision are our top priorities. Just as we emphasize strict handling protocols for our larger industrial 12V 70Ah LiFePO4 deep cycle lithium batteries, installing a high-density lithium-ion polymer phone battery requires care.

How to Install Your Battery

• Professional Install: We highly recommend taking your device to a certified technician. Modern smartphones use strong waterproof adhesives and delicate ribbon cables that can easily tear.
• DIY Approach: If you are experienced and using a complete iPhone battery replacement kit, ensure you have the exact pentalobe screwdrivers, a spudger, and fresh adhesive strips. Always drain your old battery below 25% before starting the repair to prevent thermal events if accidentally punctured.

iOS Battery Health Note

Because of Apple’s internal software tracking, here is what you need to know after installing your new Haisic HS-iP13Pro Max battery pack:

• “Important Battery Message”: You will likely see a pop-up notification in your settings stating iOS cannot verify if the battery is a genuine Apple part.
• Blank Health Percentage: The Maximum Capacity reading in your iOS Settings > Battery > Battery Health menu will show a blank dash (-) instead of a percentage.
• Full Performance: Do not worry—this is simply a software lock. Your phone remains 100% safe, and you will fully experience the massive runtime benefits of our 4770mAh iPhone battery upgrade. You are getting zero-cycle, OEM-grade performance, even if the software refuses to display the exact number.
