Quick Specifications

What Is the iPad Air 4/5 A2288 Replacement Battery?

The iPad Air 4/5 A2288 replacement battery is a rechargeable internal battery developed for compatible iPad Air 4th and 5th generation repair and refurbishment applications.

Both device generations use a 28.6Wh original battery system. The ESC A2288 replacement battery is declared at 3.83V and 7606mAh, equivalent to approximately 29.13Wh of nominal energy based on the stated voltage and capacity.

After extended charging, discharging and storage, the original tablet 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 under video, gaming or higher processor load

· The iPad operating while connected to power but shutting down soon after disconnection

A correctly matched replacement battery can restore usable battery-powered operation when the original problem is caused by battery degradation.

However, replacing the battery cannot repair faults involving the USB-C charging port, charging circuit, logic board or other internal components.

As an iPad Air battery supplier and OEM iPad battery manufacturer, ESC supplies A2288 replacement batteries for repair centers, refurbishment companies, wholesalers, distributors and private-label battery businesses.

Before ordering, buyers should verify the exact iPad generation, device model number, battery structure, connector, polarity and physical dimensions.

Key Features

1. 7606mAh Declared Capacity

The ESC A2288 replacement battery is declared at 7606mAh. Based on the stated 3.83V nominal voltage, this equals approximately 29.13Wh of nominal energy.

2. Designed for iPad Air 4 and 5 Applications

The battery is developed for compatible iPad Air 4th and 5th generation replacement projects. Exact device model, connector, battery structure and physical dimensions should still be verified before sample or bulk purchasing.

3. 3.83V Replacement Battery Platform

The ESC product specification uses a 3.83V nominal battery platform. Correct electrical and physical matching is essential for charging compatibility and stable tablet operation.

4. Integrated Battery Protection

The battery pack includes protection functions designed to help manage overcharge, over-discharge and short-circuit conditions during normal charging and operation.

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.

Technical Specifications

Different iPad generations may use different:

· Battery structures

· Rated energy specifications

· Connectors

· Flex-cable positions

· Battery dimensions

· Internal mounting layouts

Before ordering, please provide:

· Exact iPad model number

· Device generation

· Original battery photo

· Connector or flex-cable photo

· Battery dimensions

· Required quantity

Compatibility should be confirmed before sample testing or bulk production.

Original iPad Air Battery vs. ESC Replacement Battery

Important Comparison Notice

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

The original iPad Air 4th and 5th generation technical specifications state a 28.6Wh built-in rechargeable battery. The ESC A2288 replacement battery is declared at 3.83V and 7606mAh, which mathematically equals approximately 29.13Wh.

The calculated nominal-energy difference should not automatically be promoted as longer runtime. Actual usable capacity and operating time depend on:

· Battery test results

· Display brightness

· Wi-Fi or cellular usage

· Video playback

· Gaming and processor load

· Applications running in the background

· Battery temperature

· Charging-circuit condition

· Overall device condition

Customer FAQ

1. Is this battery compatible with the iPad Air 4th generation?

The ESC A2288 replacement battery is developed for compatible iPad Air 4th generation repair applications.

Supported device model references include A2316, A2324, A2325 and A2072. The original battery structure, connector and physical dimensions should still be verified before ordering.

2. Is this battery compatible with the iPad Air 5th generation?

The ESC A2288 is also intended for compatible iPad Air 5th generation repair applications.

Device model references include A2588, A2589 and A2591. Compatibility should be confirmed before sample or bulk purchasing.

3. What is A2288?

A2288 is used by ESC as the product reference for this replacement battery.

It should not be confused with the Apple model numbers used to identify the actual iPad device. The exact iPad generation and device model number should always be confirmed separately.

4. What are the ESC battery specifications?

The ESC replacement battery is declared at 3.83V and 7606mAh.

Based on these values, the calculated nominal energy is approximately 29.13Wh.

5. Why does Apple specify 28.6Wh while ESC lists the battery in mAh?

Watt-hours and milliamp-hours are different ways of expressing battery capacity.

Apple publicly specifies the original iPad Air 4 and 5 battery at 28.6Wh. ESC lists the replacement battery at 3.83V and 7606mAh, which calculates to approximately 29.13Wh.

These figures should not be treated as proof of longer runtime without actual capacity and device-level testing.

6. Will replacing the battery restore the iPad's original 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, wireless connectivity, applications, processor load, temperature and the overall condition of the device.

7. Does the replacement battery include a protection circuit?

Yes. The replacement battery includes an integrated protection system designed to help manage relevant charging, discharging and short-circuit conditions according to the final battery configuration.

8. Is the battery tested before shipment?

The battery is checked according to the applicable production and outgoing inspection process, including relevant capacity, voltage, internal resistance, connector and appearance inspections.

Specific batch-testing requirements can be discussed before bulk production.

9. Can I order a sample and customize the battery packaging?

Yes. Samples are available for compatibility and performance evaluation.

ESC also supports customized battery labels, barcode labels, retail boxes, warranty cards and outer cartons, subject to order quantity and artwork requirements.

10. Which documents and shipping support can ESC provide?

CE, RoHS, MSDS, UN38.3 and applicable battery transportation documents may be provided according to the exact battery configuration and corresponding product file.
