When it comes to small electronics like watches, remote controls, medical devices, and various gadgets, coin cell batteries are commonly used due to their compact size and long-lasting power. Two of the most widely known lithium coin batteries are the CR2450 and the CR2032. While both serve similar purposes, there are several differences between these two battery models that are important to understand when choosing the right one for your device. In this article, we will explore the differences and similarities between CR2450 vs CR2032, and also touch on related coin cell batteries such as CR2025 and CR2016.
CR2450 vs CR2032: Key Differences
The main differences between the CR2450 and CR2032 batteries lie in their size, capacity, and usage. Let’s take a closer look at each of these aspects.
1. Size:
The model numbers of coin cell batteries provide insight into their dimensions:
- CR2450: The "24" indicates a diameter of 24 mm, and the "50" refers to a thickness of 5.0 mm.
- CR2032: Similarly, the "20" means the diameter is 20 mm, and the "32" means the thickness is 3.2 mm.
As we can see, the CR2450 is larger than the CR2032. This difference in size is important because not all devices can accommodate both batteries. Devices specifically designed for 2032 batteries may not fit a 2450 due to its larger size.
2. Capacity:
Another significant difference between these two batteries is their energy capacity:
- CR2450: Typically, the CR2450 battery has a capacity ranging from 500 mAh to 600 mAh.
- CR2032: On the other hand, the CR2032 battery usually has a capacity between 200 mAh and 240 mAh.
This means the CR2450 has more than double the capacity of the CR2032, making it suitable for devices that require more energy or longer battery life.
3. Usage:
Because of the higher capacity of the CR2450, it is often used in devices that require more power or need to last longer, such as LED flashlights, medical devices, and even some wireless transmitters. The CR2032, being smaller and with less capacity, is commonly used in smaller devices like watches, calculators, and car remotes.
4. Voltage:
Both the CR2450 and CR2032 provide the same voltage of 3V, which makes them interchangeable in terms of the energy they supply. However, their different capacities mean that the CR2450 will last longer than the CR2032 when used in the same device.
2450 vs 2032: Are They Interchangeable?
One of the most common questions is whether the CR2450 and CR2032 can be swapped in a device. The answer largely depends on the device itself. Since the CR2450 is physically larger, it may not fit into a slot designed for a CR2032. However, if the device can accommodate the larger battery, then you can benefit from the longer lifespan of the CR2450.
On the other hand, using a CR2032 in place of a CR2450 might work in terms of voltage, but it would offer a shorter runtime due to the lower capacity.
Is CR2450 the Same as CR2032?
Despite similarities in voltage and purpose, the CR2450 and CR2032 are not the same battery. The key differences in size and capacity make them distinct, and they cannot always be used interchangeably without considering the device's design.
Difference Between 2032 and 2450 Batteries
To summarize the differences between 2032 and 2450 batteries, the CR2450 has a larger diameter (24 mm vs. 20 mm), greater thickness (5 mm vs. 3.2 mm), and more capacity (500-600 mAh vs. 200-240 mAh). These distinctions impact which devices they are suitable for and how long they will last in use.
Other Common Coin Batteries: CR2025 vs CR2032
When discussing coin batteries, two other models are frequently mentioned: the CR2025 and the CR2016. Both of these batteries are commonly compared with the CR2032.
• CR2025 vs CR2032: The CR2025 is slightly thinner than the CR2032 (2.5 mm vs. 3.2 mm) but shares the same diameter (20 mm) and voltage (3V). It has a lower capacity (150-170 mAh), meaning it won’t last as long as the CR2032, but it may fit in devices where space is a concern.
• CR2016 vs CR2032: The CR2016 is even thinner (1.6 mm) and has a capacity of only 90 mAh, making it suitable for ultra-thin devices, but it cannot last as long as either the CR2032 or the CR2025.
DL2032 vs CR2032: Is There a Difference?
The DL2032 and CR2032 are essentially the same battery in terms of specifications. The “DL” prefix is used by Duracell, while the “CR” prefix is the more generic term used by manufacturers like Panasonic, Sony, and Energizer. Therefore, a DL2032 is compatible with any device that requires a CR2032.
Is CR2025 the Same as CR2032?
Though the CR2025 and CR2032 have the same diameter and voltage, they are not identical due to the thickness and capacity differences. The CR2032 is thicker and offers a longer lifespan. Devices that can accommodate the extra thickness of a CR2032 may be able to use it instead of a CR2025, but the reverse may not always be possible.
CR2450 vs. CR2032: Applications
CR2450 Battery:
The Lithium Coin CR2450 batteries have several advantages in applications where standard batteries are ineffective. Calculators, digital watches, laser pens, vehicle keys, medical devices such as a clinical thermometer and a tensiometer, and workout equipment can all be stored in them.
CR2032 Battery:
Lithium Coin CR2032 has some advantages for devices that can't use regular batteries. Memory backup, digital watches, car keys, laser pens, fitness gadgets, and medical devices such as tensiometers and clinical thermometers can all benefit from this battery.
Conclusion: Choosing the Right Battery
Understanding the differences between various coin cell batteries like the CR2450 vs CR2032, CR2025, and CR2016 is essential for ensuring you choose the right battery for your device. The most important factors to consider are the size, capacity, and voltage required by your device. In most cases, it’s best to stick with the manufacturer-recommended battery type, but if you need a longer-lasting alternative and the device allows for it, upgrading to a CR2450 can provide more energy than a CR2032.
Frequently Asked Questions
Question 1: Is it possible to use CR2032 instead of CR2450?
Answer: CR2032 batteries should not be used instead of CR2450 batteries. Batteries with the CR2450 type have a higher voltage and larger capacity than batteries with the CR2032 type. In devices that require CR2450 batteries, CR2032 batteries may be less efficient and have shorter battery lifetimes.
Question 2: What is the life expectancy of a CR2032 battery?
Answer: CR2032 battery life varies depending on how much power the device consumes and how it is used. The CR2032 battery can last for several months to several years in low-power devices like calculators and small electronic gadgets. Keyless entry systems, for example, may have a shorter battery life because they consume more power.
Question 3: How to test a 2450 battery?
Answer: The voltage measurement mode on a multimeter or a battery tester can be used to test a CR2450 battery. Tester or multimeter leads should be connected to the battery terminals correspondingly. Battery voltage will be displayed, indicating how much charge the battery has left.
Question 4: Can 2032 batteries touch each other?
Answer: If two CR2032 batteries are directly in contact, the batteries could short circuit and potentially be damaged. Batteries should not have their positive and negative terminals in contact with one another.
