Battery iPhone 11

The 661-13574 is a genuine internal Lithium-ion replacement battery designed to restore an aging iPhone 11 back to its peak 100% health capacity. Because it is a certified first-party component, it resolves typical degradation issues like rapid power drain, aggressive throttling, and unexpected thermal overheating, and it will sync natively with iOS without triggering a "Genuine Parts" tracking warning flag.

Features

• Exact Component Matching: Engineered with a native capacity of3110 mAh operating at a nominal voltage of 3.83V ($11.91 \text{ Wh}$), perfectly calibrated to the power draw parameters of the iPhone 11's A13 Bionic chip.

• Integrated Gas Gauge System: Features an Apple-certified internal microcontroller board that communicates directly with iOS. This ensures your battery health metrics, cycle counts, and peak performance capabilities report accurately inside your system settings.

• Apple Service Pack Certification: Packaged inside specialized ESD (Electrostatic Discharge) protective casing specifically for clean disassemblies inside authorized technician layouts.

• True Chemistry Lifecycle: Utilizes premium, first-party cobalt lithium-ion cells engineered to hold over 80% of their baseline charge architecture through up to 500 complete system charge cycles.
