Murata CR2025 Introduction

Murata CR2025 is a lithium battery (often called a button cell) widely used in many small electronic devices.

CR2025 Common Applications:

Watches: Commonly used in watches due to its small size and long service life.

Calculators: Commonly used in small portable calculators.

Electronic Toys: Used in some small electronic toys.

Storage Devices: Used to maintain the real-time clock and set values ​​of the device, such as the CMOS battery on the computer motherboard.

Remote Controls: Used in car remote controls, TV remote controls, etc.

Is cr2032 same as cr2025?

Main differences

1.Thickness:

The thickness of CR2025 is 2.5 mm, while the thickness of CR2032 is 3.2 mm. Therefore, CR2032 is slightly thicker than CR2025.

2.Capacity:

The nominal capacity of CR2032 is usually 225 mAh, which is larger than 165 mAh of CR2025. This means that CR2032 provides longer use time, especially in devices that require higher current.

3.Weight:

Since CR2032 is thicker and has a higher capacity, it also weighs slightly more than CR2025. The weight of CR2025 is about 2.5 grams, while the weight of CR2032 is 3.0 grams.

4.Applications:

Both CR2025 and CR2032 are widely used in small devices such as watches, calculators, remote controls, electronic toys, etc. Since CR2032 offers higher capacity, it is often used in devices that require longer battery life, such as remote controls, CMOS batteries for computer motherboards, etc.

Compatibility

Size compatibility: Although both have the same diameter (20mm), the thickness of CR2025 and CR2032 is different, with CR2032 being 0.7 mm thicker than CR2025. Therefore, while some devices are designed to use both batteries, not all devices can accommodate the thicker CR2032. When installing, you need to confirm whether the size of the battery fits the design of the device.

Battery replacement: In some devices, CR2025 can be replaced with CR2032 if the battery slot is deep enough, but not vice versa, because CR2032 is thicker and cannot fit into the battery slot that fits CR2025.
