CR2450 Battery Equivalent: Compatibility and Replacement Tips
Author:admin Date: 2025-10-17 03:15 Views:24
Introduction
A CR2450 battery is a non-rechargeable lithium coin cell. It comes with a nominal voltage of 3volts, which is enough for use in small electronics. The battery chemistry and dimensions also make it good for a wide range of electronics. It is generally a good battery for offering high energy density, long shelf life, and stable voltage output.

Before we can look at the CR2450 battery equivalent, we will focus on understanding what the code CR2450 means so that when looking for an equivalent, we have a reference point.
C: This specifies the chemical composition of the battery. In this case, it is lithium manganese dioxide. Such a battery chemistry provides a stable 3-volt nominal voltage throughout the battery’s discharge cycle.
R: This indicates that the battery is round or cylindrical in shape.
24: This corresponds to the battery’s diameter of 24.5mm.
50: This corresponds to the battery’s height or thickness of 5.0mm

The common uses of the CR2450 batteries include:
- The automotive sector, where you can find them in key fobs and remotes or car security systems.
- Fitness trackers need a long-lasting power source, and that is what this battery can provide. It is the same when working with other medical devices such as glucose meters and heart rate monitors.
- Smart home and security sensors use a variety of devices that need a battery to keep working. That is why you need such a reliable battery.
- You may also encounter batteries in watches, calculators, and other small electronics.
What Does Battery Equivalent Mean?
If you are going to pick a true CR2450 3V battery equivalent, there are a few things to keep in mind. One is the physical dimensions of the potential equivalent battery. It needs to be the same as the CR2450 battery.
Another thing will be the electrical properties. That is what makes a battery perform the same as the CR2450 battery. Most of the time, the manufacturer will have a different prefix before the 2450 number, but the other part may remain the same. For example, the DL2450 from Duracell has a different name, but it still works like the CR2450 battery.
For the physical size, choose a replacement that fits in the battery compartment. This means the diameter should not exceed 24.5mm, and the height or thickness should not exceed 5.0mm. The differences in the physical dimensions can easily make a good alternative.
The nominal voltage plays a vital role as well. You need a good battery with a nominal voltage of 3.0V. Maintaining this voltage is key to preventing potential damage to the device.
As for capacity, we recommend keeping it between 600 and 620 mAh for a CR2450 battery equivalent. This indicates how long a battery can last. Choosing a battery with a lower capacity means it will die faster. Having one with a higher capacity is better.
The battery chemistry is still important as well. You are likely to come across three main options, including lithium, alkaline, and silver oxide. The CR2450 uses lithium manganese oxide chemistry, so try to match its replacement with the same chemistry. That said, you may also find some good alkaline and silver oxide batteries, but performance may vary.
The Main CR2450 Battery Equivalent Options
Here is a list of the top CR2450 battery equivalent options at the moment:

- CR2450N: It is a direct and interchangeable replacement you can use in place of the CR2450 battery. It may have minor variations, which should not affect how it fits in the battery compartment.
- DL2450: This is another direct replacement that comes from Duracell. It features the same physical dimensions and electrical properties as well.
- BR2450: This is a good direct replacement of the CR2450 battery. However, it is rechargeable, unlike when using the standard CR2450 battery. This can be good for devices that could use a rechargeable battery to save on the costs of replacing the battery often.
- LM2450: This is another common alternative you can use in place of the CR2450 battery. It is designed to be a direct replacement.
- ECR2450: This is a great alternative made by Energizer. Since it is a top brand, you can be assured of excellent performance.
Safety Risks of Non-Equivalent Batteries
We have already seen that there are multiple options for you to consider when seeking a great battery equivalent to the CR2450 battery. However, there are risks if you end up with non-equivalent batteries. Such risks include:
- Leakage and rupture depend on the power draw from the battery, or if it is heated.
- Overheating can arise from short circuits caused by having a poor fit or physical damage
- Damage to electronics is possible since you are not using the right battery with the correct electrical characteristics as expected
Top Brands Making the CR2450 Battery and Its Equivalents
We always recommend buying the CR2450 battery equivalent from a top brand. But what are these brands? Here is a quick list for you:
- Panasonic: It is known for its high-capacity and long-life batteries
- Sony: This is another reputable brand with high-quality lithium batteries
- Energizer: Another good brand in the battery market. It offers reliable CR2450 batteries.
- Duracell: Offers a direct replacement of the CR2450 battery. The difference is that it comes with a prefix “DL”
Conclusion
The CR2450 battery cell is a good pick for various electronics, as we have seen above. You can find it good even for medical devices. This is thanks to providing a steady voltage throughout its discharge time. Also, expect to come across multiple equivalents you can use if you do not get the CR2450 battery readily available. Always follow the safety measures we explained above to achieve the best performance.

Frequently Asked Questions
Can you replace the CR2450 battery with a CR2430 or CR2477?
They are not ideal replacements due to their thickness. The CR2430 is thinner at 3.0mm, so the contact will not be tight, and it also provides a shorter runtime.
The CR2477, on the other hand, may offer more capacity, but it will not fit in the battery compartment as it is bigger. Always choose the replacement battery with the correct physical dimensions for the CR2450 battery.
How long will the CR2450 battery last?
It depends on the device’s power consumption and usage frequency. So, the lifespan can be anywhere from 6 months to 5 years. Low-drain devices, such as remote sensors or clocks, will help extend their lifespans.
Is the CR2450 battery rechargeable?
No. A standard CR2450 battery is non-rechargeable. Do not attempt to recharge the battery, as it may lead to overheating, leakage, or even an explosion. Simply look for rechargeable versions such as the LIR2450 batteries. Make sure to use a proper charger as well.
