Introduction
Lithium batteries are essential for many electronic devices. Among them, button batteries (also known as button batteries) are commonly used in small devices such as car key fobs, electronic watches, hearing aids, etc. Understanding the differences between types of button batteries is crucial for consumers to ensure compatibility and optimal performance in their devices. CR2025 and CR2032 are two types of coin cell batteries that people often use. They may look similar, but there are key differences in size, capacity, and lifespan. This article will detail the differences between CR2025 and CR2032 to help you choose the right one for your needs.
Basic Overview of Lithium Battery CR2025 and CR2032
CR2025 and CR2032 batteries are both non-rechargeable lithium coin cells and come from the 'CR' series. Lithium coin cell batteries are usually designated with a CR followed by a set of numbers. The letter C stands for Lithium Manganese Dioxide. The R lets you know that the battery is round in shape. The next four digits indicate the size, the first two indicate the diameter and the last two indicate the height. All the batteries that have this chemical substance in their batteries can use the abbreviation CR.
What is a CR2032 Battery?
CR2032 3v battery is a popular type of primary lithium button cell or "coin" battery that is not rechargeable. They have a power of 3 volts and a fairly large energy capacity, depending on the manufacturer's specifications. CR2032s have a long life, good charge capacity, and stable discharge. These characteristics make them ideal for a variety of electronic devices. You can find them in car keys, security systems, remote controls, and more. CR2032s can also be fitted with connector tabs, allowing the battery to be mounted almost anywhere it is needed.
What is a CR2025 Battery?
The coin battery CR2025 is also a popular type of lithium button cell or "coin cell" battery that is not rechargeable. This battery has a diameter of 20 mm and a thickness of 2.5 mm, making this slim size ideal for devices with limited space. The CR 2025 batteries provide a stable voltage during use, which make them ideal for devices that require stable performance. The use scenarios and applications of the CR2025 battery are similar to those of the CR2032.

Frequently Asked Questions
Are CR2025 and CR2032 interchangeable?
While they are similar in size, they are not entirely interchangeable. If your device requires explicitly a CR2032 battery, using a CR2025 battery may result in improper fit or reduced performance. Always verify the battery type your device needs to avoid issues with fit or performance.
Tip: If you only have a CR 2025 and need to use it in a device designed for a CR 2032, you can make a quick fix. Fold a small piece of aluminum foil (or another metal) to fill the extra 0.7mm gap. Place it on the positive (+) side of the CR 2025, then close the battery compartment to hold everything in place. Ensure the foil makes good contact with the battery and the spring to avoid any intermittent power. While this is not the best solution, it can work to keep your device running in an emergency.
Are there any safety tips when using CR2032 and CR2025 batteries?
Store CR2025 and CR2032 batteries in a cool, dry place, away from heat and moisture. Never try to recharge them, as they can overheat or leak. Avoid short circuits by keeping the battery ends away from metal. Do not mix old and new batteries or different brands.
