Apple identifies the 2017 device family as A1670, A1671 and A1821 and publishes a 41Wh rechargeable lithium-polymer battery. The A1754 professional replacement reference is 3.77V, 10994mAh and 41.4Wh.
What Is the iPad Pro 12.9 2nd Gen A1754 Replacement Battery?
The A1754 is a rechargeable lithium-polymer replacement battery developed for compatible 2017 iPad Pro 12.9-inch 2nd generation repair and refurbishment projects.
The official device family includes:
· A1670 — Wi-Fi
· A1671 — Wi-Fi + Cellular
· A1821 — Wi-Fi + Cellular, China mainland
Apple publishes a 41Wh built-in rechargeable lithium-polymer battery for this device family. The professional A1754 replacement-battery reference is:
· 3.77V nominal voltage
· 10994mAh rated capacity
· 41.4Wh nominal energy
The difference between Apple’s 41Wh device-level specification and the 41.4Wh replacement reference may reflect rating and rounding conventions. It should not be marketed as proof of longer runtime or additional usable capacity.
An aged iPad battery may cause:
· Reduced operating time
· Rapid battery-percentage loss
· Poor charge retention
· Unexpected shutdown
· Abnormal battery-percentage changes
· Operation only while connected to power
· Reduced stability under demanding applications
A correctly matched replacement battery may restore usable battery-powered operation when degradation of the original battery is the source of the problem.
Battery replacement cannot repair faults involving the Lightning connector, charging circuit, logic board, display power system or other internal components.
As an iPad Pro 12.9 2nd Gen battery supplier, A1754 battery manufacturer and OEM iPad battery manufacturer, ESC supplies replacement batteries for repair centers, refurbishment companies, wholesalers, distributors and private-label battery businesses.
Before ordering, buyers should verify:
· Complete iPad model number
· Original battery reference
· Battery-label information
· Connector position
· Battery dimensions
· Physical installation structure
· Required quantity
· Packaging requirements

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 faults involving the Lightning port, charging circuit, logic board, display power system or other internal components.
Customer FAQ
1. What is the correct battery reference for the iPad Pro 12.9-inch 2nd generation?
The established replacement-battery reference is A1754, not A1574. The A1754 platform is specified at 3.77V, 10994mAh and 41.4Wh.
2. Why should A1574 be removed from the page?
Apple officially identifies A1574 as the model number of the iPod touch 6th generation. Using it as the primary iPad Pro battery reference creates an incorrect device relationship for buyers, search engines and AI systems.
3. Which iPad models are compatible with the A1754 battery?
The target device family includes:
· A1670
· A1671
· A1821
Apple identifies all three as 2017 iPad Pro 12.9-inch 2nd-generation models.
4. What are the correct A1754 battery specifications?
The professional replacement reference specifies:
· 3.77V nominal voltage
· 10994mAh rated capacity
· 41.4Wh nominal energy
· Lithium-polymer battery chemistry
The final ESC website data should match the physical production label and approved BOM.
5. Why does Apple specify 41Wh while the replacement battery is listed at 41.4Wh?
Apple publishes a 41Wh device-level specification, while the A1754 replacement reference is 41.4Wh. The small difference may reflect rounding and rating conventions and should not be marketed as guaranteed extra runtime.
6. Is A1754 compatible with the A1821 China mainland model?
A1821 is officially part of the same 2017 iPad Pro 12.9-inch 2nd-generation family. The original battery label, connector and physical structure should still be checked before unconditional bulk compatibility is confirmed.
7. Will replacing the battery restore the original iPad runtime?
A correctly matched replacement battery may improve runtime when the original problem is battery degradation. Actual runtime depends on screen brightness, applications, wireless use, temperature, charging conditions and overall device condition.
8. Will a new battery fix every charging or shutdown problem?
No. Battery replacement cannot repair faults involving the Lightning connector, charging circuit, logic board, power-management components or display system.
9. Can ESC customize battery labels and packaging?
ESC supports OEM services including customized battery labels, barcode labels and packaging. Samples, MOQ and customization terms should be confirmed before ordering.
10. Which documents and shipping support are available?
Applicable battery documents and shipping options depend on the exact A1754 production configuration, destination market and order quantity. Only documents verified for the exact SKU should be published or supplied.
