Product Description
The iPad Pro 12.9-inch 5th generation (2021, M1) and 6th generation (2022, M2) share an identical battery — P/N A2387, rated at 3.82V / 10566mAh / 40.11Wh. A single SKU covers all eight Apple model IDs across two production years, which matters for repair distributors managing multi-model stock: one part number, two years of coverage.
At 10566mAh, this is the largest capacity battery in Apple’s current iPad lineup. The physical dimensions are 200mm × 181mm × 2.80mm. At this size, dimensional tolerance becomes a technical risk that doesn’t apply to smaller iPad batteries. A variance of 0.2–0.3mm in cell thickness causes visible display lift or prevents proper back panel seating — the most common fitment failure in iPad Pro 12.9 battery replacement. Our cells are held to ±0.1mm tolerance across the production run, not just the first batch.

Features & Advantages
✅ 📐 ±0.1mm Dimensional Tolerance — Fitment-Critical at This Size
At 200mm × 181mm × 2.80mm, even a 0.2mm thickness overrun causes display assembly issues. Most aftermarket suppliers at this price point don’t hold dimensional spec tightly on large cells. We do — and it’s why fitment complaints on this model are rare from our customers.
✅ 🔄 One SKU, Eight Model IDs, Two Years of Coverage
iPad Pro 12.9-inch M1 (2021) and M2 (2022) use the same A2387 battery. For distributors and repair chains stocking multiple iPad Pro variants, this is straightforward: one part number handles both generations. No split inventory, no per-year ordering complexity.
✅ ⚡ PCM Rated for USB-C PD up to 30W
The iPad Pro 12.9 supports 30W USB-C Power Delivery charging. The PCM overcharge cutoff is set at 4.35V to match this input profile. Lower-rated PCM boards — common in generic aftermarket cells — are not appropriate for this charging path.
✅ 🏭 Custom Capacity and Private Label from 200 pcs
For distributors building house-brand repair kits or refurbishment lines: custom capacity within the same form factor, private label printing on the cell wrapper, and branded retail packaging are all available from 200 pcs. Serialized batch QR codes for enterprise asset tracking on request.

FAQ
Q1: Does the A2387 battery fit both the 2021 and 2022 iPad Pro 12.9-inch models?
A: Yes. Apple used the identical A2387 battery in both the iPad Pro 12.9-inch 5th generation (2021, M1) and 6th generation (2022, M2). All eight model IDs are covered: A2378, A2379, A2461, A2462 (2021) and A2436, A2437, A2764, A2766 (2022). Not compatible with 3rd Gen (2018) or 4th Gen (2020) — different P/N and connector.
Q2: Why is dimensional tolerance specifically important for this battery?
A: At 200mm × 181mm × 2.80mm, this is a large soft-pack cell. A 0.2–0.3mm thickness overrun — common in lower-grade aftermarket cells — causes the display assembly to lift visibly or prevents the back panel from seating flush. This is the most frequently reported fitment problem in iPad Pro 12.9 battery replacements. Tight dimensional control (±0.1mm) at this size requires consistent cell manufacturing — it’s not achievable with grade-B cells.
Q3: How long does the iPad Pro 12.9-inch battery last after replacement?
A: Apple’s published figure is up to 10 hours of Wi-Fi browsing or video playback. A new 10566mAh cell restores runtime to that spec. Real-world figures vary with ProMotion display refresh rate, M1/M2 background workload, and cellular signal strength — the battery capacity itself is not the variable with a correctly installed replacement.
Q4: Is custom capacity or private label available for this battery?
A: Yes, from 200 pcs. Options: custom capacity within the same physical form factor, private label on the cell wrapper, branded retail packaging, and serialized batch QR codes for asset tracking. Suitable for repair distributors building house-brand kits or enterprise refurbishment programs with tracking requirements.
Q5: Does this battery work with the iPad Pro’s ProMotion display and M1/M2 chip without any compatibility issues?
A: The battery does not interface directly with the display or chip — it’s a power source, not a data component. The PCM board handles charge/discharge protection; the BMS communicates state-of-charge to iPadOS. No compatibility flags, no ProMotion throttling, no M-chip-specific restrictions apply to the battery replacement on this model.
Q6: What should I check before installing this battery in an iPad Pro 12.9 5th or 6th gen?
A: Three things: (1) Confirm the device model number on the back housing matches A2378/A2379/A2461/A2462 (2021) or A2436/A2437/A2764/A2766 (2022). (2) Inspect the existing battery adhesive strips — iPad Pro 12.9 uses pull-tab adhesive; if tabs are broken, plan for isopropyl alcohol release. (3) Check the ZIF connector locking tab condition before disconnecting — this connector is fragile on units that have been previously opened.
