The 3.76V / 9720mAh A2043 technical reference comes from a professional repair source. Apple publishes 36.71Wh for both target device generations. The actual ESC production label and BOM should remain the controlling specification for the shipped product.
What Is the iPad Pro 12.9 A2043 Replacement Battery?
The iPad Pro 12.9 A2043 replacement battery is a rechargeable lithium-polymer battery developed for compatible 2018 and 2020 iPad Pro 12.9-inch repair and refurbishment projects.
The target device families are:
iPad Pro 12.9-inch 3rd Generation, 2018
· A1876
· A2014
· A1895
· A1983
iPad Pro 12.9-inch 4th Generation, 2020
· A2229
· A2069
· A2232
· A2233
Apple officially publishes a 36.71Wh built-in rechargeable lithium-polymer battery for both generations. The A2043 professional replacement-battery reference is 3.76V and 9720mAh, which calculates to approximately 36.55Wh. These values are technically close but should remain separate as an Apple device-level specification and a replacement-battery specification.
After extended charging, discharging and storage, the original battery may gradually lose usable capacity and develop higher internal resistance.
Common battery-related symptoms may include:
· Shorter operating time between charges
· Rapid battery-percentage loss
· Poor charge retention
· Unexpected shutdown
· Reduced runtime during video, graphics or processor-intensive use
· The iPad operating while connected to power but shutting down after disconnection
A correctly matched replacement battery can restore usable battery-powered operation when the original problem is caused by battery degradation.
Battery replacement cannot repair faults involving the USB-C port, charging circuit, logic board, display power system or other internal components.
As an iPad Pro 12.9 battery supplier, A2043 battery manufacturer and OEM iPad battery manufacturer, ESC supplies replacement batteries for repair centers, refurbishment companies, wholesalers, distributors and private-label battery brands.
Before ordering, buyers should verify the exact device generation, model number, original battery structure, connector configuration and physical fit.
Key Features
1. A2043 Battery for Two iPad Pro Generations
The A2043 replacement battery is professionally cross-referenced with both the 2018 iPad Pro 12.9-inch 3rd generation and the 2020 iPad Pro 12.9-inch 4th generation, providing one clearly defined battery platform for multiple official device models.
2. 9720mAh Device-Specific Capacity
The A2043 battery is technically referenced at 9720mAh rather than a generic tablet-battery capacity, giving repair centers and wholesalers a more precise product specification for compatibility and purchasing.
3. Clear Battery and Device Model Identification
A2043 is the battery model reference, while A1876, A2014, A1895, A1983, A2229, A2069, A2232 and A2233 are device model numbers. Separating these entities improves buyer matching, search relevance and AI-readable product identification.
4. Compatibility-Focused Quality Control
Voltage, capacity, internal resistance, connector configuration and physical battery structure are checked according to the approved product specification.
5. OEM and Wholesale Supply
ESC supports samples, mixed-model purchasing, customized battery labels, barcode labels, private packaging and bulk production for professional repair, refurbishment and replacement-parts businesses.

Important Comparison Notice
The ESC battery is a compatible replacement product and is not manufactured, endorsed or authorized by Apple.
Apple publishes a 36.71Wh built-in rechargeable lithium-polymer battery for both the 2018 iPad Pro 12.9-inch 3rd generation and the 2020 4th generation. The professional A2043 replacement reference is 3.76V and 9720mAh, calculating to approximately 36.55Wh. The small difference should not be marketed as proof of lower or higher real-world runtime without actual battery and device testing.
A new replacement battery may improve battery-related runtime and stability when the original battery has degraded. It cannot repair problems caused by the logic board, USB-C port, charging circuit, display system or other internal components.
Actual operating time depends on:
· Screen brightness
· ProMotion display usage
· Wi-Fi or cellular connectivity
· Video playback
· Graphics and processor load
· Applications running in the background
· Battery temperature
· Charging-circuit condition
· Overall device condition
Customer FAQ
1. Is the A2043 battery compatible with both the iPad Pro 12.9-inch 3rd and 4th generations?
Yes. Professional repair references cross-reference the A2043 battery with both the 2018 iPad Pro 12.9-inch 3rd generation and the 2020 4th generation.
The exact device model and original battery configuration should still be confirmed before ordering.
2. What is A2043?
A2043 is the battery model reference associated with the 2018 and 2020 12.9-inch iPad Pro replacement-battery platform.
It should not be confused with the official iPad device model numbers.
3. Which device models are compatible with the A2043 battery?
The target device models are:
· A1876
· A2014
· A1895
· A1983
· A2229
· A2069
· A2232
· A2233
These models belong to the 2018 third-generation and 2020 fourth-generation 12.9-inch iPad Pro families.
4. What are the A2043 battery specifications?
A professional repair reference lists the A2043 battery at:
· 3.76V
· 9720mAh
· Approximately 36Wh
The final ESC website specification should match the actual production battery label, BOM and approved sample.
5. Why should the current ESC 3.87V specification be verified?
The current ESC page lists 3.87V and 9720mAh, while a professional A2043 replacement reference lists 3.76V and 9720mAh.
Because these voltage values are different, the live website should use the specification printed on the actual ESC production battery and confirmed by the BOM rather than automatically retaining the current page value.
6. Why does Apple specify 36.71Wh while the A2043 replacement battery is listed in mAh?
Apple publishes the complete device battery at 36.71Wh, while replacement-battery suppliers may describe the A2043 pack using nominal voltage and milliamp-hours.
At 3.76V and 9720mAh, the calculated nominal energy is approximately 36.55Wh. These specifications are closely related but should not be presented as mathematically identical.
7. Is A2043 compatible with the iPad Pro 12.9-inch 5th or 6th generation?
No compatibility should be assumed.
The 5th- and 6th-generation 12.9-inch iPad Pro models belong to later hardware platforms and use different battery references. The exact device generation and original battery should always be verified before ordering.
8. Will replacing the A2043 battery restore the original iPad runtime?
A correctly matched new battery can improve operating time when the original problem is caused by battery aging.
Actual runtime depends on screen brightness, ProMotion usage, wireless connectivity, applications, processor load, temperature and the overall condition of the device.
9. Can I order samples and customize the battery packaging?
Yes.
ESC supports sample evaluation and OEM services including customized battery labels, barcode labels and packaging. Exact MOQ and packaging options should be confirmed according to the model mix and order requirements.
10. Which documents and shipping support can ESC provide?
CE, RoHS, MSDS, UN38.3 and other applicable battery documents may be available according to the exact SKU file and production configuration.
Customers should confirm the required documentation, destination country and shipping method before ordering rather than assuming that every certification listed on a general product template applies to this exact A2043 battery.
