Are 2025 and 2032 Batteries Interchangeable?

You've got a device that needs a battery, and you've got a drawer full of batteries. But there's a problem: some say "2025" and others say "2032." Can you just swap them out? The short answer is no, they are not interchangeable. Here's why:

Understanding Battery Sizes and Types

• 2025 and 2032 are battery sizes, specifically referring to their diameter in millimeters.
• 2025 batteries have a diameter of 20 millimeters, while 2032 batteries have a diameter of 32 millimeters.
• The size difference is significant, meaning a 2025 won't fit in a slot designed for a 2032, and vice versa.

Beyond Size: Battery Chemistry and Voltage

But it's not just about size. These battery types also differ in chemistry and voltage:

• 2025 batteries are typically lithium manganese dioxide (LiMnO2) batteries. They usually have a nominal voltage of 3 volts.
• 2032 batteries are also lithium manganese dioxide batteries. They usually have a nominal voltage of 3 volts.

**While they share a similar chemistry, the size difference means the capacity (how much energy they store) is different. ** A 2032 battery will generally have a higher capacity than a 2025, even though they share the same nominal voltage.

The Bottom Line: Don't Mix and Match

Using the wrong battery size can damage your device. It's crucial to use the battery type and size that your device is designed for.

Here's a quick breakdown:

• Need a 2025 battery? Look for a battery with a diameter of 20 millimeters.
• Need a 2032 battery? Look for a battery with a diameter of 32 millimeters.

Always check the manufacturer's instructions for your device to confirm the correct battery type.

Pro Tip: If you're unsure about the battery type, take a look at the old battery. The size and markings will be clearly visible.
