Apple officially publishes a 40.88Wh lithium-polymer battery for both device generations. The ESC page currently publishes 10566mAh and 3.85V, so the replacement battery’s exact Wh rating should be taken from the production label rather than copied from Apple’s device specification.
What Is the A2387 iPad Pro 12.9 Replacement Battery?
The A2387 is a rechargeable lithium-polymer replacement battery developed for compatible iPad Pro 12.9-inch 5th-generation and 6th-generation tablets.
The validated product relationship is:
iPad Pro 12.9-inch 5th Generation → 2021 → A2387 Battery
iPad Pro 12.9-inch 6th Generation → 2022 → A2387 Battery
The 5th-generation device family includes:
· A2378
· A2379
· A2461
· A2462
The 6th-generation device family includes:
· A2436
· A2437
· A2764
· A2766
Apple officially identifies these eight model numbers and publishes a 40.88Wh built-in rechargeable lithium-polymer battery for both generations.
An aged battery may cause:
· Reduced operating time
· Rapid battery-percentage loss
· Poor charge retention
· Unexpected shutdown
· Failure to start after storage
· Operation only while connected to power
· Unstable performance under higher device load
· Abnormal charging behavior
A correctly matched replacement battery may improve battery-powered operation when degradation of the original battery is the cause of the problem.
Battery replacement cannot repair faults involving the USB-C port, charging circuit, logic board, display, power-management system or other internal components.
As an iPad Pro 12.9 battery supplier, A2387 battery manufacturer and OEM tablet battery manufacturer, ESC supplies model-specific batteries for repair centers, refurbishment companies, wholesalers, distributors and private-label battery businesses.

Important Comparison Notice
The ESC battery is a compatible replacement product and is not manufactured, authorized, endorsed or sold by Apple.
A new battery may improve battery-related runtime and stability when the original battery has degraded. It cannot repair problems involving the USB-C port, charging circuit, logic board, display or other electronic components.
Customer FAQ
1. What is the A2387 battery?
A2387 is a replacement-battery reference used for compatible iPad Pro 12.9-inch 5th-generation 2021 and 6th-generation 2022 devices.
2. Which iPad models use the A2387 battery?
The target models are A2378, A2379, A2461, A2462, A2436, A2437, A2764 and A2766. Apple officially assigns these model numbers to the relevant two generations.
3. Is A2387 compatible with both the 5th and 6th generations?
Yes. Professional replacement references list one A2387 battery platform for both generations and all eight associated device models. The original battery structure should still be checked before ordering.
4. What capacity does the ESC A2387 battery have?
The current ESC page specifies 10566mAh. The final published capacity should match the physical ESC battery label, BOM and batch capacity-test standard.
5. What is the correct voltage for A2387?
The ESC page currently states 3.85V, while several replacement listings state 3.82V. Because external sources are inconsistent, the physical ESC production label and BOM should control the final specification.
6. Why does Apple publish 40.88Wh?
Apple publishes 40.88Wh as the built-in battery energy for the complete 5th- and 6th-generation devices. This should not automatically be assigned to an ESC replacement battery unless the ESC label confirms the same rating.
7. Will a replacement battery restore the original runtime?
It may improve runtime when the original battery has degraded. Actual runtime depends on screen brightness, applications, network use, temperature, charging conditions and the overall condition of the tablet.
8. Will an A2387 battery fix every charging problem?
No. A battery replacement cannot repair a damaged USB-C port, charging circuit, logic board, power-management system or display-related fault.
9. Can ESC customize the battery label and packaging?
Yes. ESC supports customized labels, barcodes and packaging. MOQ, sample terms and customization requirements should be confirmed before ordering.
10. What information is required for a wholesale quotation?
Provide the device model numbers, required quantities, target market, battery-label requirements, packaging specifications, certification requirements and preferred shipping method.
