2024/7/6 17:55:55


When it comes to small electronics like remote controls, key fobs, calculators, and various medical devices, coin cell batteries are indispensable. Among the most popular coin cell batteries are CR2032, DL2032, and CR2025. While they may look similar and even fit in the same devices, they have distinct differences that could impact the performance and longevity of your gadgets. We will compare the features, specs, and interchangeability of various batteries in-depth in this blog post.

DL2032 vs CR2032 - What's their Main Differences?

What are Coin Cell Batteries?

Coin Cell Batteries

Coin cell batteries, often called button cell batteries, are small, round, flat batteries that are commonly used in small electronic devices such as watches, hearing aids, calculators, and key chains. Their typical measurements are 5 to 25 millimeters in circumference and 1 to 6 millimeters in thickness. Coin cell batteries, which are frequently made of alkaline, silver oxide, or lithium materials, may power low-drain devices for a long time.

What is a CR2032 battery?

One kind of non-rechargeable lithium button cell that is frequently found in tiny electronic gadgets is the CR2032 battery. It has dimensions of 20 x 3.2 x 3.2 mm, a nominal voltage of 3 volts, and a maximum capacity of 240 mAh. Known for its long shelf life of up to 10 years, the CR2032 is widely used in various applications, including watches, calculators, key fobs, medical devices, motherboards, security system panels, and weapons sighting systems. Its small size, large capacity, long service life, and constant discharge make it an excellent choice for many commercial and consumer applications.

What is a DL2032 Battery?

A DL2032 battery is essentially the same as a CR2032 battery, with both being 3-volt lithium coin cell batteries that measure 20mm in diameter and 3.2mm in thickness. The "DL" prefix typically indicates a specific branding by Duracell, differentiating it from the more generic "CR" prefix used by other manufacturers. Both DL2032 and CR2032 batteries share the same specifications and are interchangeable in devices. They are frequently found in tiny electronic gadgets like watches, calculators, keychains, medical equipment, and many other uses that call for a dependable and long-lasting power source.

What is a CR2025 Battery?

One kind of button cell lithium battery that is frequently used in tiny electronic gadgets is the CR2025 battery. The prefix "CR" denotes "lithium manganese dioxide," which is the battery's chemical makeup. The battery's dimensions-20 mm in diameter and 2.5 mm in thickness-are indicated by the number "2025". These batteries normally have a 150–170 mAh capacity and a nominal voltage of 3 volts. Similar to the CR2032, CR2025 batteries are used in watches, calculators, key fobs, medical equipment, and small toys because of their extended shelf life. They are appropriate for devices with lesser power requirements or more compact designs because to their thinner thickness when compared to the CR2032.

They have the exact same dimensions and voltage-they are both 20 mm in diameter, 3.2 mm thick, and 3 volts. Therefore, DL2032 and CR2032 can be used interchangeably in most devices. However, due to different brands, the specific capacity and lifespan may vary. Generally speaking, DL2032 has a higher battery capacity and a longer lifespan.

Are CR2032 and CR2025 interchangeable?

Small electrical devices usually contain coin cell batteries, such as the CR2032 and CR2025. The CR2032 and CR2025 have different thicknesses of 3.2 and 2.5 mm, respectively. This is the primary distinction between them. Both batteries have the same diameter (20mm) and voltage (3V), making them generally interchangeable in devices with flexible battery compartments. However, using a CR2032 in place of a CR2025 may require more space, and a CR2025 may have a shorter lifespan compared to a CR2032 due to its smaller capacity.

Are DL2032 and CR2025 interchangeable?

Although the lithium coin cell batteries DL2032 and CR2025 are identical in size and capacity, they cannot be used interchangeably. The dimensions of the DL2032 and CR2025 are 20 mm in diameter and 3.2 mm and 2.5 mm, respectively. The DL2032 generally has a higher capacity (around 225mAh) compared to the CR2025 (around 160mAh). Devices designed for one type may not properly fit or function with the other.

How to Test Coin Cell Batteries

Using a Multimeter

1. Set the Multimeter:

- Power On: Turn on your multimeter.
- DC Voltage Setting: Select the DC voltage setting on the multimeter. Typically, a "V" with a straight line under it and a dashed line above it indicates this.

2. Connect Probes:

- Red Probe: Place the red probe on the positive terminal (the flat, larger side) of the battery.
- Black Probe: Place the black probe on the negative terminal (the smaller, rounded side) of the battery.
- Secure Contact: To obtain an accurate reading, make sure the probes are in good contact with the terminals.

3. Read Voltage:

- Check Display: Look at the multimeter display for the voltage reading.
- Fully Charged Battery: A fully charged 3V coin cell battery should show a voltage close to 3 volts (e.g., 2.8V to 3.2V).
- Low Voltage: If the reading is significantly lower (e.g., below 2.5V), it indicates the battery is weak or depleted and should be replaced.

Using Battery Testers

1. Dedicated Battery Testers:

- Device Design: Battery testers are compact devices specifically designed to test small batteries, including coin cells.
- Easy to Use: They typically have slots or contacts where you place the battery to get a reading.

2. Testing Process:

- Insert Battery: Place the coin cell battery into the designated slot or contacts on the tester, ensuring correct polarity (positive and negative alignment).
- Read Indicator: The tester will indicate the battery's status, often with a needle or digital display showing "Good," "Weak," or "Replace."
- Fast Results: The battery's remaining charge level can be quickly and clearly determined using this method.

Tips for Accurate Testing

 - Clean Contacts: Ensure the battery terminals and multimeter or tester probes are clean for accurate readings.

 - Room Temperature: Test batteries at room temperature for best results, as extreme temperatures can affect voltage readings.

 - Compare Readings: If uncertain, compare readings with a new battery to understand the typical voltage range for your specific tester or multimeter.

By following these steps, you can effectively test your coin cell batteries, ensuring your devices operate efficiently and reducing the risk of unexpected power loss.(Attached below is the video)
