Choosing the correct battery for your device can be daunting, especially when faced with multiple options. Two popular choices are the CR2430 battery and the 2354 battery. These batteries are commonly used in various electronic devices, including watches, calculators, and medical devices. This article will guide you through the differences, similarities, and considerations to help you make an informed decision.

Understanding the Basics

CR2430 batteries and 2354 batteries are both coin cell batteries known for their small size and reliability. These batteries are often used in low-power devices that require a steady voltage over a long period.

CR2430 Battery

The CR2430 battery is a lithium coin cell battery with a diameter of 24mm and a thickness of 3.0mm. It operates at a voltage of 3V, making it suitable for devices that need a consistent power supply. Brands like Varta CR2430 and Duracell DL2430 are well-known for their high-quality CR 2430 batteries.

CR2354 Battery

The 2354 battery is slightly different. It has a diameter of 23mm and a thickness of 5.4mm. Like the CR2430, it also operates at 3V. The Panasonic CR2354 3V battery is one of the most popular choices in this category, and it is known for its reliability and longevity. The battery CR2354 3V is often used in devices requiring a larger capacity than what a CR2430 might offer.

Key Differences

  1. Size and Shape: The most apparent difference is in the dimensions. The CR2430 is thinner at 3.0mm, whereas the CR2354 is thicker at 5.4mm. This difference in thickness can significantly impact whether a battery will fit into your device.
  2. Capacity: Due to its larger size, the Panasonic CR2354 battery typically has a higher capacity than the CR2430. This means it can last longer in devices with higher power consumption.
  3. Compatibility: While some devices can accommodate both batteries, most are designed for one type. Always check your device’s specifications before choosing a battery.

Choosing the Right Battery

When deciding between a CR2430 battery and a 2354 battery, consider the following factors:

  1. Device Specifications: Check your device’s user manual or existing battery. The manufacturer usually specifies which battery is required. If your device explicitly states it needs a battery CR 2430, then a lithium battery CR2430 3V is what you need. Similarly, if it calls for a batteri CR 2354, you should use the battery CR2354 3V.
  2. Battery Life: If your device is compatible with both, consider how often you want to replace the battery. The Panasonic CR2354 battery typically offers a longer lifespan due to its higher capacity. This can be particularly beneficial for devices that are difficult to access or use too much power.
  3. Availability: Consider where you can purchase the batteries. Some might find it easier to locate a CR2430 battery near me. Both Varta CR2430 and Duracell DL2430 are widely available and trusted brands.
  4. Cost: Price can also be a deciding factor. Generally, the 2354 battery might be slightly more expensive due to its higher capacity. However, prices can vary based on brand and retailer.
  5. Brand Preference: Brands like Panasonic and Duracell have established reputations for producing reliable batteries. If brand reliability is essential to you, sticking with a trusted name might be worth the extra cost.

Common Applications

CR2430 batteries are commonly used in:

  • Small electronics like watches and calculators
  • Medical devices such as glucose monitors
  • Small remote controls

2354 batteries are typically found in:

  • Larger remote controls
  • Medical devices requiring higher power
  • Electronic toys and games

CR2354 Battery Equivalent

If you find it challenging to locate a Panasonic CR2354 3V battery, CR2354 battery equivalent options are available. Ensure that any equivalent you choose matches the voltage and size specifications of the original battery to avoid any compatibility issues.

When in doubt, refer to your device’s manual for the recommended battery type. For those who prioritize longevity and can accommodate a slightly thicker battery, the Panasonic CR2354 battery is an excellent choice. However, for a thinner option that is widely available, the CR2430 battery from brands like Varta and Duracell might be more convenient.


Choosing between a CR2430 and a 2354 battery ultimately comes down to your device’s requirements and personal preferences regarding battery life and brand. While both batteries serve similar functions, their differences in size and capacity can make one more suitable than the other for specific devices.
