One of the commonly asked questions about AirTag is the type of battery it uses. In this article, we will delve into the details and provide you with comprehensive information about the battery used in AirTag.

The Battery Type

AirTag is powered by a standard CR2032 coin cell battery. This type of battery is widely available and can easily be replaced when it runs out of power. CR2032 batteries are commonly used in various electronic devices due to their compact size and long-lasting performance. With this battery, AirTag can typically operate for about a year before requiring a battery replacement.

Battery Replacement Process

When the battery of your AirTag needs to be replaced, you can easily do it yourself. Follow these simple steps:

Step 1: Open the AirTag

Locate the white plastic side of the AirTag and press firmly while twisting it counterclockwise. This will unlock the cover and allow you to remove it.

Step 2: Remove the Old Battery

Once the cover is removed, you will see the CR2032 battery. Use your finger or a small tool to carefully lift it out of the AirTag.

Step 3: Insert the New Battery

Take a new CR2032 battery and place it into the designated slot, ensuring the positive side is facing up.

Step 4: Close the AirTag

Align the cover back onto the AirTag and press firmly while twisting it clockwise. This will lock the cover in place.

Battery Life and Notifications

The battery life of an AirTag depends on various factors, such as the frequency of use and the distance from your iPhone. On average, it can last up to a year before requiring a replacement. Additionally, you will receive a notification on your iPhone when the battery level of your AirTag is low. This allows you to proactively replace the battery and ensure smooth functionality.

Preserving Battery Life

To maximize the battery life of your AirTag, consider the following tips:

1. Optimize Precision Finding

Precision Finding is a feature that helps you locate your AirTag with precision. However, it utilizes more battery power. Enable this feature only when necessary to conserve battery life.

2. Use the Sleep Mode

AirTag automatically enters a low-power Sleep Mode when it is not in motion for a certain period. This helps conserve battery power when you are not actively using it.

3. Keep AirTag Close to Your iPhone

If your AirTag is too far away from your iPhone, it may consume more battery power to maintain a stable connection. Keeping the AirTag in close proximity to your iPhone can help preserve its battery life.


AirTag uses a CR2032 coin cell battery, which provides long-lasting power for approximately a year. Replacing the battery is a simple process that can be done by following a few steps. By following the tips mentioned above, you can effectively preserve the battery life of your AirTag. Now that you know the type of battery AirTag uses, you can confidently utilize this innovative device to keep track of your belongings.
