Apple identifies the iPad 2 device models as A1395, A1396 and A1397 and publishes a 25Wh lithium-polymer battery specification. The professional A1376 replacement reference is 3.8V / 6500mAh / 25Wh.


What Is the iPad 2 A1376 Replacement Battery?

The iPad 2 A1376 replacement battery is a rechargeable lithium-polymer battery developed for compatible 2011 iPad 2 repair and refurbishment projects.

The target device family includes:

· A1395 — iPad 2 Wi-Fi

· A1396 — iPad 2 GSM

· A1397 — iPad 2 CDMA

Apple officially publishes a 25Wh built-in rechargeable lithium-polymer battery for the iPad 2. The current ESC A1376 replacement battery is specified at 3.82V and 6500mAh, which calculates to approximately 24.83Wh. A professional A1376 replacement reference lists 3.8V, 6500mAh and 25Wh.

These specifications are closely aligned, but they should be described accurately:

· 25Wh is Apple’s public device-level battery specification.

· 6500mAh / 3.82V is the current ESC replacement-product specification.

· 6930mAh has been reported on the label of an original iPad 2 battery during teardown and should not automatically be used as the declared capacity of the ESC replacement battery.

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 or application 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 problem is caused by battery degradation.

Battery replacement cannot repair faults involving the 30-pin charging connector, charging circuit, logic board, display power system or other internal components.

As an iPad 2 battery supplier, A1376 battery manufacturer 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, original battery configuration and physical compatibility.

Professional replacement recommended

Apple publishes 25Wh for the iPad 2 battery system. An original-device teardown reports 6930mAh on the physical original battery label, while the professional A1376 replacement specification is 6500mAh / 3.8V / 25Wh. The ESC replacement battery is currently declared at 6500mAh / 3.82V, or approximately 24.83Wh. These values should remain clearly distinguished rather than presenting the ESC battery as a 6930mAh original-capacity battery.

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 faults involving the logic board, 30-pin charging connector, charging circuit, display system or other internal components.

Actual operating time depends on:

· Screen brightness

· Wi-Fi or mobile-data usage

· Video playback

· Applications and processor load

· Battery temperature

· Charging-circuit condition

· Overall device condition

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

Yes. A1376 is a recognized replacement-battery model for the iPad 2 platform.

The target device model numbers are A1395, A1396 and A1397. The original battery structure and connector configuration should still be confirmed before ordering.

2. What is A1376?

A1376 is the battery model reference associated with the iPad 2 replacement-battery platform.

It should not be confused with the official device model numbers A1395, A1396 and A1397.

3. What is the capacity of the ESC A1376 replacement battery?

The current ESC product specification is 6500mAh.

This matches a professional A1376 replacement-battery reference that also lists 6500mAh.

4. Why do some original iPad 2 battery references show 6930mAh?

An original-device teardown reports 6930mAh on the physical battery label, while Apple publishes the complete battery system at 25Wh and professional replacement references commonly list A1376 at 6500mAh / 3.8V / 25Wh.

Different published capacity figures can reflect battery-rating methodology and the relationship between voltage, energy and discharge conditions. The ESC product should be sold according to its actual tested and labeled specification rather than automatically using the highest original-pack mAh figure.

5. Is 6500mAh lower than the original iPad 2 battery?

The ESC battery is declared at 6500mAh and 3.82V, equal to approximately 24.83Wh.

Apple officially specifies the iPad 2 battery system at 25Wh. Therefore, energy in watt-hours provides a more useful comparison than comparing the ESC 6500mAh figure directly with a 6930mAh marking found on an original battery label.

6. Should the ESC battery voltage be 3.82V or 3.8V?

The current ESC page lists 3.82V, while a professional A1376 replacement reference lists 3.8V.

The difference is small, and the final website specification should match the actual ESC production battery label, BOM and approved sample rather than being changed solely to match a third-party listing.

7. Is A1376 compatible with all iPad generations?

No.

A1376 is associated with the iPad 2 platform. Later iPad generations use different battery structures and specifications. Battery selection should be based on the exact device model and original battery configuration.

8. Will replacing the A1376 battery fix every charging or shutdown problem?

No.

Battery replacement may address problems caused by battery degradation, including reduced runtime or battery-related shutdown. It cannot repair faults involving the 30-pin charging connector, charging circuit, logic board or other internal components.

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

Yes.

ESC supports sample evaluation and OEM services including customized battery labels, barcode labels and packaging. Exact sample terms, MOQ and packaging options should be confirmed according to the model mix and order requirements because the current page contains inconsistent MOQ information.

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 A1376 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 general product template applies to this exact battery model.

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.
