Apple identifies iPhone 16 model numbers as A3081, A3286, A3287 and A3288, depending on the sales region.
Important specification check: the shown label states 3560mAh, 3.88V and 13.39Wh. A 3560mAh battery at 3.88V mathematically corresponds to approximately 13.81Wh, so the capacity, voltage and Wh marking should be reconciled on the final production label before publishing or mass production.

Apple's Parts and Service History distinguishes genuine, used and unknown parts based on device and repair circumstances. Repair Assistant may also be required to finish certain supported repairs.
For this reason, claims such as "Genuine," "100% Battery Health," "No Unknown Part" or "No Pop-Up" should be validated on the exact diagnostic battery version and current iOS before being guaranteed in product marketing.
Diagnostic Battery Functions
Battery Replacement Testing
Technicians can use the battery as part of a professional repair workflow to verify device charging, discharge and battery-related operation after installation.
Battery Data Verification
Depending on the battery electronics, diagnostic solutions may support battery-data reading and repair-related verification.
Post-Repair Device Testing
After installation, technicians should verify charging, Battery Health behavior, Parts and Service History, temperature and system messages.
iOS Compatibility Validation
Diagnostic functionality should be retested after major iOS updates because system-level parts verification and battery-data handling can change.
Apple continues to use Parts and Service History and Repair Assistant as part of its repair ecosystem.
Quality Control Process
Capacity Testing
Each production batch should be tested to verify that measured discharge capacity meets the approved 3560mAh specification.
Voltage and Internal Resistance Testing
Voltage and internal resistance should be measured to identify abnormal cells before assembly or shipment.
Diagnostic Function Testing
The selected diagnostic electronics should be tested on an actual iPhone 16 with the intended iOS environment.
Charging and Discharging Testing
Battery charging behavior, discharge stability, temperature and protection functions should be checked before shipment.
Connector and Flex Inspection
Connector position, flex alignment, welding quality and electrical continuity should be inspected to reduce installation failures.
Aging Testing
Aging tests help identify abnormal self-discharge, unstable cells and premature electrical failure.
Final Device Validation
Professional diagnostic batteries should be tested not only electrically but also in a real device for recognition, charging and repair-related behavior.
OEM and Private Label Service
Custom Battery Labels
Custom labels can include brand name, capacity, voltage, model reference, barcode, batch number and traceability information.
Private Label Packaging
Retail boxes and wholesale packaging can be developed for repair brands, distributors and e-commerce sellers.
