iPhone 15 Pro Max - Diagnostic OEM battery for fast triage
This iPhone 15 Pro Max - Diagnostic OEM Battery is built for repair benches that need repeatable power-up, charge, and current draw testing without committing a customer battery. Model id: A3102. Fits model: iPhone 15 Pro Max.
Key electrical data is tuned for the device, with a typical capacity of 4422 mAh, a nominal voltage of 3.88 V, and an energy rating of .95 Wh. The pack uses a lithium‑ion polymer cell and a matched flex that aligns with the iPhone 15 Pro Max battery bay and connector geometry. Gas gauge communication is supported for stable charge and discharge metrics during diagnostics. Cycle count is zero, so you start with a fresh baseline for intake checks, board troubleshooting, and post-repair verification.
Technical data and compatibility for repair benches
Capacity: 4422 mAh typical. Voltage: 3.88 V nominal. Energy: 16.95 Wh typical. Chemistry: Li‑ion polymer pouch. Connector: iPhone 15 Pro Max battery flex with correct length and pad layout. Cycle count: Zero. Compatibility: iOS 17 or later. Model id: A3102. Fits model: iPhone 15 Pro Max.
This diagnostic pack supports stable boot loops, restore sessions, current profiling, and charge acceptance checks on bench power workflows. The build focuses on consistent output and accurate response to charge controllers under common repair scenarios, including board-level evaluation, display swaps, camera service, and intake screening where on‑off cycles and repeated reseats are routine.
Installation, safety, and workflow tips
Power down the device, remove any remaining adhesive, and confirm the tray is clean and flat before seating the cell. Align the flex without over‑bending, click the connector straight down, and avoid creasing the pouch. Use pull‑tab battery adhesive for temporary or permanent installs as your workflow requires, or secure the pack for short bench runs with low‑residue tape to speed repeat diagnostics.
Boot toOS and confirm battery metrics, charge rate, and idle draw in your preferred diagnostic suite. Run a full top‑off and a controlled discharge to validate stability if you are qualifying a refurbished unit. Store the battery at a partial state of charge in a cool, dry environment when not in active use. Follow standard Li‑ion handling practices, and replace any pack that shows swelling, unusual heat, or mechanical damage during intake.
