Product Description
The iPhone 12 series — spanning the mini, standard, Pro, and Pro Max — collectively represents one of the highest-volume battery replacement segments in the global repair market. Despite this, most aftermarket batteries in this category still trigger Apple’s “Unknown Part” or “Important Battery Message” alert on iOS 16 and later, creating friction for repair operators and reducing end-customer satisfaction.
This product line solves that problem at the hardware level. Each unit ships with a fully integrated TI gas gauge IC and self-diagnostic BMS board, pre-programmed at the factory. No secondary programming tool, no BMS transplant from the donor battery, no firmware adjustment required. Install, reassemble, power on — the device immediately reads 100% Battery Health with no warning message.
All three capacity variants are detailed on this page. Contact our B2B sales team to specify model quantities when placing a wholesale order.

Features & Advantages
⚡ High Capacity Across All Models — Extended Runtime Over OEM
Each model is rated above the original Apple specification:
| Model | OEM Capacity | This Battery | Increase |
|---|---|---|---|
| iPhone 12 mini | 2227mAh | 2580mAh | +15.8% |
| iPhone 12 / 12 Pro | 2815mAh | 3350mAh | +19.0% |
| iPhone 12 Pro Max | 3687mAh | 4320mAh | +17.2% |
All capacities measured at 3.85V nominal under standard IEC discharge conditions. All units install in the original battery bay without case modification or bracket replacement.
🔬 Pure Cobalt (LiCoO2) Cell — Not Standard Li-Polymer
Most aftermarket units reduce cost by substituting NMC or blended polymer cells. All models in this line use a Pure Cobalt (LiCoO2) cathode — the same cell chemistry used in original Apple batteries. This delivers a tighter voltage discharge curve, lower self-discharge rate, and better capacity retention across 500+ charge cycles. For repair shops operating under a service warranty, cell chemistry directly affects return rates and shop liability.
✅ Zero Pop-Up — TI Chip + Self-Diagnostic BMS
A Texas Instruments gas gauge IC is pre-soldered to the flex cable of each unit. The BMS communicates with iOS via Apple’s authentication protocol. Compatible with iOS 16, 17, and 18.x. Post-installation Battery Health reads 100% with no “Unknown Part” or “Important Battery Message” warning. No additional programming or donor board transplant required at the repair bench.
🔋 Brand New 0 Cycle — Not Reconditioned or Pulled
Every unit ships with a BMS-verified cycle count of 0. These are not pulled batteries from used devices, reconditioned cells, or machine-cycled refurbished stock. Shelf life from manufacture: up to 12 months stored at 40–60% charge state, 15–25°C ambient temperature.

No. All models include a TI gas gauge IC and self-diagnostic BMS board pre-programmed at the factory. After installation on any iPhone 12 model — mini, standard, Pro, or Pro Max — the device reads 100% Battery Health with no pop-up warning on iOS 16, 17, or 18.x. No donor BMS transplant is required.
Q2: Which iPhone 12 models are covered on this product page?
This page covers the full iPhone 12 lineup across all regional variants: iPhone 12 mini (A2399/A2176/A2398/A2400), iPhone 12 (A2172/A2402/A2404/A2403), iPhone 12 Pro (A2341/A2406/A2408/A2407), and iPhone 12 Pro Max (A2342/A2410/A2412/A2411). Specifications for all three capacity options are listed on this page. Confirm your device model at Settings → General → About before ordering.
Q3: Why are the capacities higher than the original Apple batteries?
The capacity increase across all models comes from the Pure Cobalt (LiCoO2) cathode, which delivers higher energy density within the same physical cell dimensions as the original. All capacities — 2580mAh, 3350mAh, and 4320mAh — are measured at 3.85V nominal under standard IEC discharge conditions. All units install in the original battery bay without modification.
Q4: Can I order different models in the same wholesale batch?
Yes. All three models — 12 mini, 12 & 12 Pro, and 12 Pro Max — are available from the same supplier. Contact our B2B sales team to specify quantities per model when placing a wholesale order. Tiered pricing, sample availability, and lead time are confirmed by our sales team based on order volume.
Q5: What certifications does this product carry, and is it eligible for air freight?
Each production batch carries CE, RoHS, FCC, and MSDS certifications. MSDS documentation confirms UN38.3 compliance, making all models eligible for air freight with standard lithium battery declaration and sea freight. Full documentation is available on request for customs and import compliance.
Q6: What warranty applies, and how are defective units handled?
Every unit carries a 12-month warranty from shipment date. Units confirmed dead on arrival or failing to display 100% Battery Health after correct installation are replaced or credited. All units pass 100% capacity testing before packing, with batch pass rate documented before dispatch.
