Quick Specifications

Apple identifies the target 2017 device family as A1670, A1671 and A1821 and publishes a 41Wh battery specification. The professional A1754 replacement reference is 3.77V, 10994mAh and 41.4Wh.

What Is the iPad Pro 12.9 2nd Gen A1754 Replacement Battery?

The iPad Pro 12.9 2nd Gen A1754 replacement battery is a rechargeable lithium-polymer battery developed for compatible 2017 iPad Pro 12.9-inch repair and refurbishment projects.

Apple identifies the target device as the iPad Pro 12.9-inch (2nd generation) with the following device model numbers:

· A1670

· A1671

· A1821

Apple publishes a 41Wh built-in rechargeable lithium-polymer battery for this device family. The professional A1754 replacement-battery reference is 3.77V, 10994mAh and 41.4Wh. These should be presented as related but separate device-level and replacement-product specifications rather than forced into one identical value.

After extended charging, discharging and storage, an 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 Lightning port, charging circuit, logic board, display power system or other internal components.

As an iPad Pro 12.9 2nd Gen battery supplier 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 model number, original battery configuration, connector structure and physical fit.

Key Features

1. Correct 2017 iPad Pro 12.9-Inch Platform

The battery is developed for the 2017 iPad Pro 12.9-inch 2nd-generation platform, officially identified by Apple as device models A1670, A1671 and A1821.

2. 10994mAh A1754 Replacement Capacity

Voltage, capacity, internal resistance, connector configuration and physical battery structure are important in professional iPad battery replacement and should be checked against the approved production specification.

5. OEM and Wholesale Supply

ESC supports samples, mixed-model purchasing, customized battery labels, barcode labels, private packaging and bulk production for repair, refurbishment and replacement-parts businesses.

Technical Specifications

The A1754 technical values above come from a professional replacement-battery reference, while Apple’s official public device specification is 41Wh. The actual ESC production label, BOM and approved sample should remain the controlling specification for the shipped product.

Compatible Models

Apple officially identifies A1670, A1671 and A1821 as the model numbers of the 2017 iPad Pro 12.9-inch 2nd-generation family.

Compatibility Notice

A1754 is used as the primary replacement-battery reference for this page and should not be confused with the official iPad device model numbers.

The existing ESC reference A1574 requires careful handling. Some aftermarket battery catalogs associate A1574 with the 12.9-inch iPad Pro 2nd generation, but Apple officially identifies A1574 as the model number of the 2015 iPod touch 6th generation. For clearer Google and AI entity recognition, A1574 should not be used as the sole primary identifier unless the physical ESC battery label and internal BOM specifically use that reference.

This battery should not automatically be described as compatible with:

· iPad Pro 12.9-inch 1st Generation

· iPad Pro 12.9-inch 3rd Generation

· Later 12.9-inch iPad Pro generations

· Other iPad models based only on screen size

Different generations may use different:

· Battery references

· Voltage specifications

· Capacity specifications

· Battery structures

· Connectors

· Flex-cable positions

· Internal mounting layouts

Before ordering, please provide:

· Exact iPad model number

· Device generation

· Original battery photo

· Battery-label photo

· Connector or flex-cable photo

· Required quantity

Compatibility should be confirmed before sample testing or bulk production.

Original iPad Pro 12.9 2nd Gen Battery vs. ESC Replacement Battery

Apple publishes a 41Wh battery specification for the 2017 iPad Pro 12.9-inch 2nd generation, while the professional A1754 replacement reference is 3.77V, 10994mAh and 41.4Wh. The 0.4Wh difference should be shown as a distinction between Apple’s public device-level specification and the replacement-battery reference rather than marketed as guaranteed additional runtime.

Important Comparison Notice

The ESC battery is a compatible replacement product and is not manufactured, endorsed or authorized by Apple.

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, Lightning 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

Apple specifies up to 10 hours of Wi-Fi web browsing, video viewing or music listening under its test conditions, but this should not be presented as a guaranteed runtime for a replacement battery.

Customer FAQ

1. Is the A1754 battery compatible with the iPad Pro 12.9-inch 2nd generation?

The A1754 replacement battery is associated with the 2017 iPad Pro 12.9-inch 2nd-generation platform.

The official device model numbers are A1670, A1671 and A1821. The original battery structure and connector configuration should still be confirmed before ordering.

2. What is A1754?

A1754 is a professional replacement-battery reference associated with the 2017 iPad Pro 12.9-inch 2nd generation.

It should not be confused with the official iPad device model numbers A1670, A1671 and A1821.

3. Why does the current ESC page use A1574 instead of A1754?

The current ESC page uses A1574, and some aftermarket catalogs also use A1574 for this battery application. However, professional repair references identify the 2017 iPad Pro 12.9-inch 2nd-generation battery as A1754.

A1574 also creates an entity conflict because Apple officially uses A1574 as the model number of the iPod touch 6th generation.

For clearer product identification, the actual ESC battery label and BOM should be checked. If the physical product is marked A1754, A1754 should become the primary page reference.

4. Why should the current 4000mAh specification be removed?

The current ESC page uses a generic 4000mAh / 3.87V parameter block, but the professional A1754 reference for the iPad Pro 12.9-inch 2nd generation is 10994mAh, 3.77V and 41.4Wh.

The existing 4000mAh specification is therefore not consistent with the target device and battery platform.

5. What are the A1754 replacement-battery specifications?

The professional A1754 replacement reference is:

· 3.77V nominal voltage

· 10994mAh capacity

· 41.4Wh energy

The final ESC website specification should still match the actual ESC production label, BOM and approved battery sample.

6. Why does Apple specify 41Wh while the A1754 replacement battery is listed at 41.4Wh?

Apple publishes the complete device battery at 41Wh, while the professional A1754 replacement reference is listed at 41.4Wh.

The difference is small and may reflect rating conventions, rounding or the way device-level and battery-pack specifications are published. It should not automatically be marketed as longer operating time.

7. Is the battery compatible with the A1821 China mainland model?

Apple identifies A1821 as a China-mainland cellular version of the 2017 iPad Pro 12.9-inch 2nd generation.

Because professional replacement listings may not always separately list every regional model, the original battery label, connector and physical structure should be confirmed before bulk ordering.

8. Will replacing the battery restore the original iPad runtime?

A correctly matched new battery can improve operating time when the original problem is caused by battery degradation.

Actual runtime depends on screen brightness, ProMotion use, wireless connectivity, applications, processor load, temperature and the overall condition of the device. Apple’s published runtime figures are test-condition references rather than guarantees for a replacement battery.

9. Can I order samples and customize the battery packaging?

ESC supports sample evaluation and OEM services including customized battery labels and packaging.

Exact sample terms, MOQ and packaging options should be confirmed according to the current model mix and order requirements because the existing ESC page contains inconsistent MOQ statements.

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 generic product template applies to this exact battery model.
