Apple officially publishes a 40.88Wh lithium-polymer battery for both device generations. The ESC page currently publishes 10566mAh and 3.85V, so the replacement battery’s exact Wh rating should be taken from the production label rather than copied from Apple’s device specification.


What Is the A2387 iPad Pro 12.9 Replacement Battery?

The A2387 is a rechargeable lithium-polymer replacement battery developed for compatible iPad Pro 12.9-inch 5th-generation and 6th-generation tablets.

The validated product relationship is:

iPad Pro 12.9-inch 5th Generation → 2021 → A2387 Battery

iPad Pro 12.9-inch 6th Generation → 2022 → A2387 Battery

The 5th-generation device family includes:

· A2378

· A2379

· A2461

· A2462

The 6th-generation device family includes:

· A2436

· A2437

· A2764

· A2766

Apple officially identifies these eight model numbers and publishes a 40.88Wh built-in rechargeable lithium-polymer battery for both generations.

An aged battery may cause:

· Reduced operating time

· Rapid battery-percentage loss

· Poor charge retention

· Unexpected shutdown

· Failure to start after storage

· Operation only while connected to power

· Unstable performance under higher device load

· Abnormal charging behavior

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

Battery replacement cannot repair faults involving the USB-C port, charging circuit, logic board, display, power-management system or other internal components.

As an iPad Pro 12.9 battery supplier, A2387 battery manufacturer and OEM tablet battery manufacturer, ESC supplies model-specific batteries for repair centers, refurbishment companies, wholesalers, distributors and private-label battery businesses.

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 problems involving the USB-C port, charging circuit, logic board, display or other electronic components.


Customer FAQ

1. What is the A2387 battery?

A2387 is a replacement-battery reference used for compatible iPad Pro 12.9-inch 5th-generation 2021 and 6th-generation 2022 devices.

2. Which iPad models use the A2387 battery?

The target models are A2378, A2379, A2461, A2462, A2436, A2437, A2764 and A2766. Apple officially assigns these model numbers to the relevant two generations.

3. Is A2387 compatible with both the 5th and 6th generations?

Yes. Professional replacement references list one A2387 battery platform for both generations and all eight associated device models. The original battery structure should still be checked before ordering.

4. What capacity does the ESC A2387 battery have?

The current ESC page specifies 10566mAh. The final published capacity should match the physical ESC battery label, BOM and batch capacity-test standard.

5. What is the correct voltage for A2387?

The ESC page currently states 3.85V, while several replacement listings state 3.82V. Because external sources are inconsistent, the physical ESC production label and BOM should control the final specification.

6. Why does Apple publish 40.88Wh?

Apple publishes 40.88Wh as the built-in battery energy for the complete 5th- and 6th-generation devices. This should not automatically be assigned to an ESC replacement battery unless the ESC label confirms the same rating.

7. Will a replacement battery restore the original runtime?

It may improve runtime when the original battery has degraded. Actual runtime depends on screen brightness, applications, network use, temperature, charging conditions and the overall condition of the tablet.

8. Will an A2387 battery fix every charging problem?

No. A battery replacement cannot repair a damaged USB-C port, charging circuit, logic board, power-management system or display-related fault.

9. Can ESC customize the battery label and packaging?

Yes. ESC supports customized labels, barcodes and packaging. MOQ, sample terms and customization requirements should be confirmed before ordering.

10. What information is required for a wholesale quotation?

Provide the device model numbers, required quantities, target market, battery-label requirements, packaging specifications, certification requirements and preferred shipping method.

Tips to Choose the Good Quality Power Bank

Power Bank Selection: Assess Your Needs

The first step is to determine your power needs based on the devices you plan to charge. For high-demand devices (like laptops and tablets), choose a high-capacity power bank, such as 20,000mAh or 30,000mAh. For smartphones and smaller gadgets, a capacity of around 10,000mAh is usually enough.
1

Look for Fast Charging

Prioritize power banks that support fast charging technologies to save time. Look specifically for Power Delivery (PD) or Quick Charge (QC). These features allow compatible devices to charge much faster, significantly cutting down charging time.
2

Check Ports and Compatibility

Look at the number and type of output ports on the power bank. Most power banks have USB-A ports. If you need to charge modern devices (like laptops or new phones), make sure the power bank includes a USB-C (or other specialized) port. Multiple ports are essential if you need to charge several devices at the same time.
3

Evaluate Safety Features

Safety is crucial for any portable charger. Always look for power banks that include built-in safety mechanisms: • Overcharge protection • Short-circuit protection • Temperature control These features protect both your devices and the power bank while charging.
4

Consider Brand Reputation and Quality

Always select a power bank from a reputable brand known for quality and reliability. Trusted brands use premium components and conduct rigorous quality checks. This ensures excellent performance and durability, giving you a product that will last.
5

Think About Portability and Design

Consider the power bank's size, weight, and overall design. For travel or everyday carry, choose a model that is compact and lightweight enough to fit easily into your pocket or bag. You may also want features like sleek designs, LED indicators, or ergonomic shapes for better convenience.
6

Read Customer Reviews

Before you buy, make sure to read customer reviews and ratings. Real user experiences offer valuable insights into the product's performance, reliability, and durability that you won't find anywhere else.
7

Check Compatibility

Always confirm that the power bank is compatible with your devices. It must be able to support the specific charging requirements (voltage, current) of your smartphone, tablet, laptop, or any other gadget you intend to charge.
8

Compare Price and Warranty

Compare prices based on the features, capacity, and brand reputation. Find a power bank that offers a good balance between price and performance within your budget. Check the manufacturer's warranty. A longer warranty period is a strong indicator of the brand's confidence in its product quality.
