Why Choose ESC

Model-Specific iPad Battery Supply

ESC matches replacement batteries using the exact iPad generation, official device model number, internal battery reference, nominal voltage, capacity, connector and physical structure.

Professional A1664 Battery Manufacturer

As an A1664 battery manufacturer and iPad Pro 9.7 battery supplier, ESC supports professional repair, refurbishment, wholesale and replacement-parts programs.

Compatibility-Focused Quality Control

Applicable inspection may include capacity, voltage, internal resistance, connector configuration, protection-board function, appearance and physical compatibility according to the approved product specification.

OEM and Private-Label Support

As an OEM iPad battery manufacturer, ESC supports customized battery labels, barcode labels, retail packaging, warranty materials, inner cartons and export cartons.

Samples and Mixed-Model Wholesale Orders

Samples can be arranged for installation and functional evaluation. Mixed-model purchasing, MOQ and packaging requirements should be confirmed according to the selected product list and current production plan.

The current ESC page states OEM support and a 12-month warranty, but final commercial terms should be confirmed in the quotation.

Quick Specifications

The A1664 technical reference is 3.82V, 7306mAh and 27.91Wh. Apple’s public device-level specification is 27.5Wh. These values should be shown separately rather than described as identical.

What Is the iPad Pro 9.7 A1664 Replacement Battery?

The A1664 is a rechargeable lithium-polymer replacement battery developed for compatible 2016 iPad Pro 9.7-inch repair and refurbishment projects.

The official device family includes:

· A1673 — iPad Pro 9.7-inch Wi-Fi

· A1674 — iPad Pro 9.7-inch Wi-Fi + Cellular

· A1675 — iPad Pro 9.7-inch Wi-Fi + Cellular

Apple publishes a 27.5Wh built-in rechargeable lithium-polymer battery for this device family. The physical A1664 battery platform is technically referenced at:

· 3.82V nominal voltage

· 7306mAh capacity

· 27.91Wh energy

The difference between 27.5Wh and 27.91Wh should be treated as a distinction between Apple’s public device-level specification and the battery-pack label or replacement-market reference. It should not be promoted as guaranteed additional runtime.

An aged battery may cause:

· Reduced operating time

· Rapid battery-percentage loss

· Poor charge retention

· Unexpected shutdown

· Failure to operate after power is disconnected

· Abnormal charging behavior

· Reduced stability under higher device load

A correctly matched replacement battery may restore battery-powered operation when degradation of the original battery is the cause of the fault.

Battery replacement cannot repair problems involving the Lightning connector, charging circuit, logic board, display power system or other internal components.

As an iPad replacement battery factory, wholesale iPad Pro battery supplier and OEM iPad battery manufacturer, ESC supplies A1664 batteries for repair centers, refurbishment companies, distributors, wholesalers and private-label battery businesses.

Key Features

1. Correct A1664 Battery Platform

A1664 is the battery model associated with the 2016 iPad Pro 9.7-inch platform and should be connected clearly with device models A1673, A1674 and A1675.

2. 7306mAh Device-Specific Capacity

The A1664 battery is rated at 7306mAh, providing a technically relevant product specification rather than a generic tablet-battery capacity.

3. 3.82V and 27.91Wh Technical Reference

The physical battery and professional repair reference support 3.82V and 27.91Wh. The existing ESC 3.85V value should not remain unless confirmed by the actual production battery.

4. Compatibility-Focused Verification

The official device model, original battery label, connector, physical structure and dimensions should be checked before sample testing or bulk production.

5. OEM and Wholesale Supply

ESC supports samples, mixed-model purchasing, customized battery labels, barcodes, private packaging and bulk supply for professional tablet repair and refurbishment markets.

Technical Specifications

The actual ESC production label, BOM and approved sample should remain the controlling specification for the shipped battery.

Compatible Models

Apple officially identifies A1673, A1674 and A1675 as the 2016 iPad Pro 9.7-inch family. The professional repair source directly lists A1673 and A1674 for A1664.

Compatibility Notice

A1664 is the battery model reference and should not be confused with the official iPad device model numbers.

This battery should not automatically be listed for:

· iPad Air models

· iPad 5th or 6th generation

· iPad Pro 10.5-inch

· iPad Pro 11-inch

· iPad Pro 12.9-inch

· Other 9.7-inch iPads based only on screen size

Before ordering, provide:

· Exact device model number

· Original battery-label photo

· Original connector photo

· Battery dimensions

· Required quantity

· Packaging requirements

Matching the screen size alone is not sufficient to confirm battery compatibility.

Original iPad Pro 9.7 Battery vs. ESC A1664 Replacement Battery

Apple states up to ten hours of Wi-Fi web use, video playback or music playback and up to nine hours of cellular web use under its testing conditions. These figures apply to the complete device and should not be presented as guaranteed replacement-battery runtime.

Important Comparison Notice

The ESC battery is a compatible replacement product and is not manufactured, endorsed, authorized 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 system or other internal components.

Customer FAQ

1. Is A1664 compatible with the iPad Pro 9.7-inch?

A1664 is the battery model associated with the 2016 iPad Pro 9.7-inch platform. The official device models are A1673, A1674 and A1675. Compatibility should still be checked against the original battery and connector.

2. What are the correct A1664 battery specifications?

The established A1664 specification is:

· 3.82V

· 7306mAh

· 27.91Wh

· Lithium-polymer battery

The final ESC website specification should match the physical production label and BOM.

3. Is the current ESC 7306mAh capacity correct?

Yes. The current ESC page, the original battery teardown and the professional replacement reference all identify the capacity as 7306mAh.

4. Why should the current 3.85V value be corrected?

The current page lists 3.85V, while the physical A1664 battery and professional repair reference specify 3.82V. At 7306mAh, 3.82V also aligns with the published 27.91Wh battery rating.

5. Why does Apple state 27.5Wh while A1664 is labeled 27.91Wh?

Apple publishes a 27.5Wh device-level battery specification, while the physical A1664 battery label and repair reference state 27.91Wh. The difference may reflect rating and publishing conventions and should not be marketed as guaranteed extra runtime.

6. Is A1664 compatible with model A1675?

A1675 is officially part of the 2016 iPad Pro 9.7-inch cellular family. Because the professional repair reference directly lists A1673 and A1674, the original battery label and physical configuration of A1675 should be checked before unconditional compatibility is published.

7. Will replacing the battery restore the original device runtime?

A correctly matched new battery may improve runtime when the original problem is battery degradation. Actual runtime depends on screen brightness, Wi-Fi or cellular use, applications, temperature 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 the battery label and packaging?

Yes. ESC supports OEM services including customized battery labels, barcodes and packaging. Sample terms, MOQ and customization requirements should be confirmed before ordering.

10. Which documents and shipping support are available?

Applicable battery documents and shipping options depend on the exact A1664 production configuration, destination country and order quantity. Only documents verified for this specific SKU should be published or supplied.
