Why Is the CR2032 Battery Compatible with AirTag?
The CR2032 battery is compatible with AirTag because it meets the specific power requirements and physical size needed for the device. The AirTag utilizes a coin cell design, and the CR2032 fits within this design, ensuring proper functionality.
According to the Battery Council International, a reputable source on battery information, a CR2032 is a lithium coin cell battery with a nominal voltage of 3 volts and a capacity of approximately 220 mAh. This specification makes it suitable for low-drain devices.
The compatibility of the CR2032 battery with AirTag arises from a few key factors. First, the AirTag requires a power source that provides 3 volts—this matches the output of the CR2032. Second, the CR2032 battery has a diameter of 20 millimeters and a thickness of 3.2 millimeters, which is the exact size required for the AirTag’s battery compartment. This precise dimension ensures that the battery fits snugly within the device, facilitating a proper connection for power.
Technical terms such as “nominal voltage” refer to the standard voltage that a device operates at, while “capacity” indicates the amount of energy the battery can store and supply over time. The compatibility of the CR2032 also hinges on its lithium chemistry, which supports reliable performance and a longer shelf life than many other battery types.
In summary, the CR2032 battery’s design accommodates the AirTag’s requirements. Under normal conditions, such as proper insertion of the battery and maintaining good contact with the battery terminals, the AirTag operates effectively. For instance, when using the AirTag in a keychain tracker, the battery’s ability to supply consistent voltage allows for effective communication with connected devices and efficient tracking of your belongings.
How Long Can You Expect the CR2032 Battery to Last in an AirTag?
The CR2032 battery in an AirTag typically lasts about one year under normal usage conditions. AirTags are designed to operate efficiently, providing a good balance between performance and battery life.
Battery lifespan can vary based on several factors. The frequency of use and the amount of time the AirTag is in active tracking mode can influence battery life. For instance, if you use the AirTag frequently to locate lost items, the battery might drain faster. Conversely, if the AirTag is used less often, it may last longer than the average of one year.
In practical scenarios, if an AirTag is attached to a piece of luggage that you use regularly, it may experience more tracking requests, which can reduce the battery’s lifespan. An AirTag placed on a rarely used bike might extend its battery life because it is not actively being pinged as often.
Environmental conditions can also impact battery performance. Extreme temperatures can affect battery efficiency. Cold weather can temporarily decrease battery life, while high temperatures may potentially shorten its overall lifespan.
In summary, you can expect the CR2032 battery in an AirTag to last around one year, influenced by usage frequency, tracking demands, and environmental conditions. For those considering long-term use, monitoring battery levels through the AirTag’s connected app may be beneficial.

- CR2016 Battery
- Rechargeable Lithium Batteries
- Higher-Capacity Alternatives (e.g., CR2450)
These alternatives vary in size, capacity, and compatibility with the AirTag. Some users may prefer rechargeable options for sustainability, while others might prioritize longer battery life.
The following sections will provide a detailed explanation of each alternative battery type.
-
CR2025 Battery:
The CR2025 battery is thinner than the CR2032 battery, measuring 2.5 mm in thickness compared to the 3.2 mm thickness of the CR2032. While it can physically fit in an AirTag, it has a lower capacity of 160 mAh, as opposed to the 220 mAh of the CR2032. This means users may experience shorter operational life. However, it can still work as a stopgap solution if the CR2032 is unavailable. -
CR2016 Battery:
The CR2016 battery is even thinner, measuring only 1.6 mm in thickness. It offers a capacity of around 90 mAh, which is considerably lower than both the CR2032 and CR2025. Although it can fit in the AirTag, the significantly reduced capacity leads to poor battery performance and will not provide satisfactory service for extended periods. This option is typically not recommended for optimum AirTag operation. -
Rechargeable Lithium Batteries:
Rechargeable lithium batteries can serve as a sustainable alternative to disposable batteries for AirTags. Some rechargeable models can fit within the same housing. These batteries offer the convenience of multiple uses and can be charged without discarding. However, they often have varying voltages and may not maintain the same performance level as the CR2032, leading to concerns about reliability. -
Higher-Capacity Alternatives (e.g., CR2450):
Higher-capacity alternatives like the CR2450 can provide much longer battery life than the CR2032 due to their larger size and capacity (typically around 500 mAh). However, the CR2450 is larger in diameter and thicker, making it incompatible with AirTag designs. Despite this, some consumers may find utility in modifying other devices where this battery type fits.
In conclusion, when considering alternatives to the CR2032 for AirTag use, each option comes with its own set of advantages and disadvantages. It’s crucial to weigh the factors of size, capacity, and battery life to ensure optimal performance.
