CR2032 vs DL2032: What’s the Difference?

Both the CR2032 and DL2032 batteries are the same size, having a diameter of 20mm and a thickness of 3.2mm. They both deliver 3 volts of power and are made using Lithium Manganese Dioxide (Li-MnO2) as their main component. These batteries can function well across a wide range of temperatures, from -20°C to +60°C, making them suitable for many everyday devices.

CR2032 Overview

The CR2032 battery is well-known for its ability to hold a lot of energy for its size. It provides steady power, allowing devices to run smoothly over time without frequent interruptions. One of its strengths is its ability to prevent leaks, which helps protect your devices from damage. The battery also discharges its power at a steady rate, which means it uses its energy efficiently. This helps extend the battery life, reducing the need for frequent replacements. Additionally, the CR2032 is recognized for its long-lasting power, often outliving regular dry-cell batteries that you might find in other small electronics.

DL2032 Overview

The DL2032 battery shares the same voltage and size as the CR2032, but it is designed to offer a bit more in terms of performance. It’s a battery made to last longer, especially in devices that require a steady supply of power, like calculators, watches, or medical devices. This battery is packed with a higher energy level, which makes it suitable for gadgets that may need a bit more power to function well. Compared to the CR2032, the DL2032 can deliver a higher amount of energy more quickly, which helps it keep up with devices that draw power more frequently or at higher levels. This means that whether a device is used occasionally or continuously, the DL2032 can supply a more consistent current, which helps your devices run without sudden drops in performance.

CR2032 vs DL2032: Key Differences

Although the CR2032 and DL2032 look nearly identical, there are some small differences that you should know before choosing between them. Understanding these differences can help you pick the right one for your needs.

• Battery Maker

The main difference between these two batteries is who makes them. The "CR" in CR2032 means it follows a common naming system used by many battery manufacturers. On the other hand, the "DL" in DL2032 tells you that it’s made by Duracell. In terms of performance, they’re very similar, but the "DL" is simply Duracell’s version of the CR2032.

• Battery Capacity

The DL2032 can store a bit more energy than the CR2032. For example, while a CR2032 typically holds around 220 mAh, a DL2032 can store 240 mAh. This difference allows the DL2032 to last a little longer before you need to replace it, which can be useful if you want a battery that will keep your device powered up for a longer period.

• Dimension and Weight

Although the CR2032 and DL2032 both have the same diameter of 20mm, there’s a small difference in their weight and thickness. The CR2032 usually weighs about 3.0g, while the DL2032 weighs a bit more at around 8g. The DL2032 is also slightly thicker, at 0.86mm, compared to the CR2032. This difference is mostly due to Duracell’s design adjustments, which allow the DL2032 to store a little more energy. However, the extra thickness and weight are so small that they won’t make a noticeable difference when you’re handling or installing the battery in most devices.

CR2032 vs CR2016: Which Battery Should You Choose?

The CR2016 battery is thinner than the CR2032. The CR2016 has a thickness of 1.6 mm, while the CR2032 is 3.2 mm thick. Despite this difference, both batteries share the same diameter of 20 mm and produce the same 3 volts of power.

CR2016 Overview

CR2016 batteries are widely used in everyday electronic devices. You’ll often find them in calculators, digital watches, car key remotes, laser pointers, toys, fitness devices, and various medical equipment like thermometers and tensiometers. These batteries perform well in small devices where regular batteries aren’t practical, providing a reliable power source over time.

CR2032 VS CR2016: Differences

• Cell Numbers

The numbers on the batteries tell you about their size. The first two digits represent the diameter (20 mm for both), and the last two digits indicate the thickness (1.6 mm for the CR2016, 3.2 mm for the CR2032). This means the CR2032 is twice as thick as the CR2016, even though they have the same diameter.

• Capacity

Battery capacity, measured in milliampere-hours (mAh), indicates how long the battery will last before it needs replacing. A typical CR2016 battery has a capacity of around 90 mAh. If your device draws a 15 mA load, this battery should last about six hours. On the other hand, the CR2032 offers a higher capacity—around 240 mAh. If your device uses 24 mA, the CR2032 will last roughly 10 hours, giving you more usage time between changes.

• Thickness

The CR2016 is only 1.6 mm thick, making it suitable for devices that require a slim battery. In contrast, the CR2032 is 3.2 mm thick, offering more power due to its larger size.

Usage Note

While both batteries provide the same 3 volts, they are not interchangeable because of their different thicknesses. If you try to stack two CR2016 batteries to replace a single CR2032, the result would be a combined 6 volts. This higher voltage could damage your device, so it's important to use the right battery type for your equipment. Always match the battery type recommended for your device to ensure it works properly and avoids potential damage.

CR2032 vs CR2025: What’s the Difference?

CR2025 Overview

The CR2025 is a small, round coin cell battery that you might find in devices like wristwatches, pocket calculators, car key remotes, and hearing aids. These batteries are compact and typically range from 5 to 25mm in diameter, with a height between 1 and 6mm. The name itself helps describe the size: "20" refers to its diameter of 20mm, and "25" means the thickness is 2.5mm.

CR2032 VS CR2025: Differences

• Thickness

The main difference between these two batteries is their thickness. The CR2032 is 3.2mm thick, while the CR2025 is 2.5mm. The extra thickness of the CR2032 gives it a bit more power.

• Capacity (mAh)

Since the CR2032 is slightly thicker, it can hold more energy. The CR2032 has a capacity of around 225mAh, which allows it to power your device for longer. In comparison, the CR2025 typically has a capacity of about 160mAh. This means that while both batteries might fit the same devices, the CR2032 will generally last longer before needing to be replaced.

Usage Note

Even though these batteries have the same diameter and voltage (3 volts), their difference in thickness means they aren’t always interchangeable. If your device is designed to hold a CR2025, trying to fit a thicker CR2032 might not work, and vice versa. Devices that require a longer-lasting battery or draw more power will often use the CR2032. But for smaller gadgets that don’t use as much energy, the slimmer CR2025 might be a better fit.

Conclusion

This article compared popular coin-cell batteries like the CR2032, DL2032, CR2016, and CR2025. While they may look alike, they differ in thickness, capacity, and usage. The DL2032 holds a bit more power than the CR2032, though they’re the same size. The CR2016 is thinner and stores less energy, and the CR2025 is also slimmer but doesn’t last as long as the CR2032.

In short, choosing the right battery depends on your device's power needs and size. Make sure to use the correct battery to keep your gadgets running smoothly for longer.

Frequently Asked Questions [FAQ]

1. Is the CR2450 the same as the CR2032?

The CR2450 and CR2032 batteries use the same type of technology, which means they store energy in a similar way. However, the CR2450 is larger, so it can hold more power compared to the CR2032.

2. Can you swap a CR2016 battery for a CR2032?

The CR2016 and CR2032 share the same voltage and diameter, which might make you think they can be swapped. However, the CR2016 is much thinner. If it fits in the battery compartment and makes proper contact, you could use it, but it won't last as long as the CR2032 because it holds less power.

3. Is there a replacement for the CR2032?

The CR2032 is a popular lithium battery used in many devices. If needed, you could use a CR2025 as a substitute, since it’s also a coin-cell battery, but it won’t last as long because it stores a little less power.

4. Why should I choose a CR2032 instead of a CR2016?

A CR2032 will run about four times longer than a CR2016 due to its larger size. Also, because it’s bigger, it’s often a better choice for toys and other devices where safety is a concern, as it’s harder to accidentally swallow.

5. How long does a CR2032 battery last?

How long a CR2032 battery lasts depends on a few things, like where it’s stored and how old it is. Generally, these batteries can last anywhere from a few months to up to ten years if stored properly.
