The CR2430 battery is a small, coin-shaped lithium cell frequently used in compact, low-power electronic devices. Its name signifies its composition and size: 'CR' refers to Lithium and Carbon Monofluoride chemistry, while '2430' indicates a diameter of 24mm and height of 3mm. It is non-rechargeable and offers a nominal voltage of 3V, with a typical capacity ranging between 270-320mAh. Remarkable for its stable voltage and long shelf life of up to 10 years, it's an ideal choice for devices like wristwatches, calculators, car keys, medical instruments, and more. Despite their utility, these batteries pose a swallowing risk and demand careful handling, especially around children and pets.

CR 2430 Battery Specifications
The CR2430 battery, a type of coin or button cell, is favored for its stability, compact size, and longevity. Here are its key specifications:
| Specification | Description |
|---|
| Chemistry | Lithium Carbon Monofluoride (LiCoO2) |

| Capacity | Typically between 270-320 milliampere-hours (mAh) |
| Shelf Life | Typically 5 to 10 years under proper storage conditions |
| Temperature Tolerance | Wide range, making it suitable for various environments |
| Rechargeability | Non-rechargeable, must be replaced after energy depletion |
| Applications | Used in watches, calculators, car remotes, medical devices, etc. |
| Safety Concerns | No harmful substances but poses a swallowing risk, so should be kept out of reach of children and pets |
CR2430 Battery Equivalent
While the CR2430 is a specific type of battery, there are some alternatives or equivalents available that could work in the same application if the CR2430 isn't on hand. Here are some equivalent batteries to the CR2430:
DL2430: This is Duracell's version of the lithium coin battery.
BR2430: Batteries with the BR designation have a slightly different composition, using carbon monofluoride lithium instead of manganese. This leads to a slightly better temperature tolerance and longer shelf life, but their discharge may be below the needs of some high-drain devices.
ECR2430: This is Energizer's term for this type of battery.
The LIR2430 3.6V rechargeable button lithium battery can serve as an alternative to the CR2430. Even though their sizes are identical, the voltage of the LIR2430 battery is higher than that of the CR2430. Therefore, when choosing an alternative battery, one should consider the specific needs of the device and the performance parameters of the battery.
These CR2430 replacement batteries are "size compatible," meaning that a device designed to accept a CR2430-sized battery can physically accept either of the above batteries. This does not necessarily mean an exact match in chemistry or voltage.
Finally, never attempt to replace a CR2430 with any battery that is not of the same size (i.e. 24mm diameter, 3.0mm height), as doing so may damage your device or cause it to not function properly.
CR2450 vs CR2430 Battery
The CR2430 and CR2450 batteries are similar in terms of their chemistry and voltage, but they differ primarily in their physical size and power capacity:
1. Size: The most noticeable difference lies in their dimensions. Both batteries share the same diameter - 24mm. The difference is in the height. "2430" stands for a diameter of 24mm and a height of 3.0mm, whereas "2450" stands for a diameter of 24mm and a height of 5.0mm. So, the CR2450 battery is thicker than the CR2430.
2. Capacity: Due to the larger size, the CR2450 generally has a larger power capacity compared to the CR2430. On average, a CR2450 battery might have a capacity of around 600 to 620 mAh, while a CR2430 tends to have a capacity of around 270-300 mAh.
3. Applications: Because of their difference in size and capacity, these batteries could be used in different types of devices. A CR2450 might be found in devices that require a bit more energy, such as certain types of digital scales, medical devices, or larger flashlights.
It's important to note that even though they have the same diameter, the thickness difference might prevent them from being used interchangeably in certain devices. Always check your device's battery requirements before attempting to substitute a different battery model.

Frequently Asked Questions
1. Are CR2430 and CR2032 interchangeable?
No, CR2430 and CR2032 batteries are not interchangeable. The numbers in their names represent their dimensions - CR2032 is 20mm in diameter and 3.2mm thick, while CR2430 is 24.5mm in diameter and 3.0mm thick. Even though they both have the same voltage (3V), their capacity, physical size, and potential energy are different.
2. Are CR2430 and CR2450 interchangeable?
No, CR2430 and CR2450 batteries are not interchangeable. While they are similar in diameter (24.5mm for both), the latter is thicker (5.0mm for CR2450 as opposed to 3.0mm for CR2430) and tends to have a higher capacity. This can lead to problems with fit and may affect the device's functionality.
3. What is the Difference Between CR2430 and CR2450?
CR2430 and CR2450 are both types of lithium coin cell batteries with the same diameter (24.5mm). The main difference lies in their thickness and capacity. CR2430 is 3.0mm thick, while CR2450 is 5.0mm thick, leading to higher capacity in CR2450.
4. How thick is a CR2430 Battery?
A CR2430 battery is 3.0mm thick.
5. What Battery Can Replace CR2430?
CR2430 batteries can potentially be replaced with ECR2430, DL2430, BR2430, and LIR2430 batteries due to their identical physical sizes. However, it's crucial to account for differences in these batteries' characteristics. ECR2430 and DL2430 are essentially equivalents to CR2430, differing mainly by manufacturer. BR2430 batteries are high-temperature variants with potentially lower capacity, whereas LIR2430 batteries are rechargeable with a higher voltage.
