When it comes to button batteries, two of the most common sizes are the 2025 and 2032. Both batteries are 3 volts, but there are some key differences between them.
The 2025 battery is smaller than the 2032 battery, with a diameter of 20 mm and a height of 2.5 mm. The 2032 battery has a diameter of 20 mm and a height of 3.2 mm. This difference in size means that the 2025 battery has less capacity than the 2032 battery.
The 2025 battery is typically used in smaller devices, such as watches and calculators. The 2032 battery is typically used in larger devices, such as car key fobs and medical devices.
When choosing a button battery for your device, it is important to consult the device’s manual to determine which size battery is required. Using the wrong size battery can damage your device.
1. Size
Size is an important factor to consider when choosing a button battery. The size of the battery will determine how much power it can store and how long it will last. The two most common sizes of button batteries are the 2025 and 2032. The 2025 battery is smaller than the 2032 battery, with a diameter of 20 mm and a height of 2.5 mm. The 2032 battery has a diameter of 20 mm and a height of 3.2 mm.
The difference in size between the 2025 and 2032 batteries means that the 2032 battery has a greater capacity than the 2025 battery. This means that the 2032 battery will last longer than the 2025 battery in the same device.
It is important to choose the correct size battery for your device. If you use a battery that is too small, it will not be able to provide enough power to operate the device. If you use a battery that is too large, it may not fit into the device or it may damage the device.
When choosing a button battery for your device, be sure to consult the device’s manual to determine which size battery is required.
2. Capacity
The capacity of a battery is a measure of how much charge it can store. The capacity of a button battery is measured in milliamp-hours (mAh). The higher the mAh rating, the more charge the battery can store and the longer it will last.
The 2025 battery has a capacity of 160 mAh, while the 2032 battery has a capacity of 220 mAh. This means that the 2032 battery can store more charge and will last longer than the 2025 battery in the same device.
The capacity of a battery is an important factor to consider when choosing a battery for your device. If you need a battery that will last for a long time, you should choose a battery with a high mAh rating.
3. Applications
The applications of 2025 and 2032 batteries vary depending on their size and capacity. The 2025 battery is often used in smaller devices, such as watches, calculators, and key fobs. The 2032 battery is often used in larger devices, such as car key fobs, medical devices, and toys.
- Watches and clocks: Both 2025 and 2032 batteries are commonly used in watches and clocks. The 2025 battery is typically used in smaller watches, while the 2032 battery is typically used in larger watches and clocks.
- Calculators: 2025 batteries are often used in calculators, as they are small and have a long lifespan.
- Key fobs: 2025 and 2032 batteries are both used in key fobs, depending on the size of the key fob and the power requirements of the fob’s electronics.
- Medical devices: 2032 batteries are often used in medical devices, as they have a high capacity and can provide a long lifespan.
When choosing a battery for a particular application, it is important to consider the size, capacity, and power requirements of the device. The 2025 battery is a good choice for small devices with low power requirements, while the 2032 battery is a good choice for larger devices with higher power requirements.
4. Cost
The cost of a button battery can vary depending on the size, capacity, and brand of the battery. In general, 2025 batteries are less expensive than 2032 batteries. This is because 2025 batteries are smaller and have a lower capacity than 2032 batteries.
The cost of a button battery can also vary depending on where you purchase it. Button batteries can be purchased at a variety of retail stores, including grocery stores, hardware stores, and electronics stores. The cost of a button battery can also vary depending on whether you purchase it online or in a store.
When choosing a button battery for your device, it is important to consider the cost of the battery. If you are on a budget, you may want to choose a less expensive battery. However, if you need a battery that will last for a long time, you may want to choose a more expensive battery.
