iPhone 16 Pro Max 4685mAh Pure Cobalt Battery Cell for BMS Swapping
- 100% pure cobalt bare cell matching original 4685mAh capacity.
- Pre-tinned positive/negative nickel tabs optimized for factory-level BMS spot welding.
- Zero-cycle guarantee with strict internal resistance grading.
- Bypasses Apple’s “Unknown Part” warning when paired with original IC.
- Direct factory wholesale pricing with flexible MOQ for global repair networks.
Product Description
As the mobile repair industry shifts towards IC transplantation to retain battery health data and bypass system warnings, sourcing reliable bare cells is critical. This replacement cell is engineered specifically for the iPhone 16 Pro Max (Compatible with models A3296, A3297, A3084). By utilizing 100% pure cobalt material, this cell matches the exact 4685mAh capacity and energy density of the OEM part. It is supplied as a bare cell without the Battery Management System (BMS) flex cable, requiring technicians to spot weld the original IC board onto the provided pre-tinned nickel tabs. We supply these directly from our automated production lines to repair depots globally, ensuring stable voltage curves and minimal defect rates.

Features & Advantages
✅ 🔋 100% Pure Cobalt Architecture
Unlike standard ternary lithium or mixed-material cells, pure cobalt construction ensures high volumetric energy density and stable discharge rates under heavy loads, crucial for the thermal demands of the iPhone 16 Pro Max A18 Pro chip.
✅ 🛠️ Optimized for BMS Swapping
The nickel tabs are precision-cut and pre-tinned. This reduces the heat required during spot welding, protecting the cell’s integrity while ensuring a solid, low-resistance connection to the original Apple BMS board.
✅ 📊 Graded Internal Resistance
Every cell in our wholesale batches undergoes automated capacity grading and internal resistance (IR) testing. Consistent IR values prevent premature voltage drops and ensure the device reads accurate battery percentages post-repair.
✅ 🏭 Factory-Direct Scalability
We eliminate middleman markups by shipping directly from our manufacturing facility. We support flexible sample orders for initial quality testing and scale up to high-volume bulk shipments with full Dangerous Goods (DG) compliance.

FAQ
Q: Does this cell require spot welding to the original BMS? A: Yes. This is a bare battery cell. Technicians must use a battery spot welder to attach the original iPhone 16 Pro Max BMS flex cable to the nickel tabs on this cell.
Q: Will this trigger the “Unknown Part” message in iOS? A: No, provided the spot welding is done correctly using the original BMS board. Since the device recognizes the original IC, it will read the battery as genuine and retain battery health percentage data.
Q: What is the real capacity of this 16 Pro Max cell? A: The cell is manufactured and tested to deliver a true 4685mAh capacity, strictly matching the original equipment manufacturer specifications.
Q: What is your minimum order quantity (MOQ) for wholesale? A: We support a flexible B2B structure. You can order small batches for bench testing before committing to our standard volume tiers which unlock maximum wholesale discounts.
Q: What kind of warranty do you provide for bulk orders? A: We provide a 12-month defect warranty covering issues like premature swelling or rapid voltage drop, assuming standard installation procedures were followed.
Q: How do you handle shipping for bulk lithium batteries? A: We use specialized DG (Dangerous Goods) freight forwarders. Depending on your region, we offer air freight for rapid delivery or sea freight for cost-effective large volume shipping, including customs clearance support.
