CR1220 vs CR1225

In spite of their similar size and shape, CR1220 and CR1225 batteries differ in several important ways. Lithium coins can be found in watches, calculators, key fobs, and other electronic devices. Both CR1220s and CR1225s are made from the same material, but they differ in their thickness, capacity, and power output, making them unsuitable for all applications. The purpose of this guide is to help you choose the right battery for your needs by exploring the key differences, features, and uses of these two batteries.

What is a CR1220 Battery?

What is CR1220 Battery?

It is commonly found in compact electronic devices as a small, coin-shaped lithium battery called the CR1220. Designed to fit into small spaces, this lightweight battery has a diameter of 12mm and a thickness of 2.0mm. In addition to watches, calculators, car key fobs, and small medical equipment, it operates at a nominal voltage of 3V. The "CR" designation means it is a lithium coin cell whose lithium chemistry is indicated by the "C" and the round shape is indicated by the "R".

In addition to its long shelf life, the CR1220 battery has a lithium composition that makes it capable of lasting up to five years when stored correctly. Moreover, this battery maintains its performance over time, allowing devices to operate smoothly without frequent replacement. In spite of its small size, the CR1220 is very effective and is used in applications that require long-lasting power and size constraints. You can also learn about Pushbutton Switches too.

What is a CR1225 Battery?

What is CR1225 Battery?

Small electronic devices commonly use the compact CR1225 lithium battery. Several low-power applications include watches, calculators, car key fobs, and small medical devices can benefit from the 3V nominal voltage of this device, measuring 12mm in diameter and 2.5mm in thickness. CR stands for lithium chemistry and R stands for round shape, indicating that it is a lithium-based coin battery. Compact in size, this battery delivers reliable power over an extended period of time while fitting into compact devices.

Its long shelf life makes it a convenient choice for devices that aren't in constant need of power, making it a great choice for those devices. Devices operate smoothly without having to replace batteries frequently because of the device's stable voltage output. As a trusted power source for various everyday gadgets and specialized equipment, the CR1225 battery balances size, energy efficiency, and longevity.

CR1220 vs CR1225: Differences

Size and Thickness

In terms of thickness, CR1220 batteries differ from CR1225 batteries. The CR1220 and CR1225 batteries have the same 12mm diameter, but the thickness of the CR1220 is 2.0mm, while the thickness of the CR1225 is 2.5mm. Since the CR1225 has a greater thickness, it can carry more energy, making it a more suitable power source for long-lasting devices. When swapping these batteries, be sure to check the device specifications before swapping the thicker CR1225 with the slimmer CR1220.

Capacity and Performance

The energy capacity of these two batteries is another significant difference. CR1225 batteries typically have a higher capacity, around 50mAh, than CR1220 batteries, which have an average capacity of 35mAh. Its increased capacity makes the CR1225 ideal for applications that are dependent on long-lasting energy, since it can power devices for a much longer period of time than the CR1220. Consequently, the CR1225 is typically used for frequent or longer-lasting devices, while the CR1220 is suitable for low-drain or intermittent devices.

Battery Lifespan

There is a difference in duration between the CR1220 battery and the CR1225 battery due to their different capacities. In comparison with the CR1225, which has a capacity of approximately 50mAh, the CR1220 typically has a lower capacity (around 35mAh). CR1225's high capacity makes it ideal for long-term battery life, especially in continuous power applications. The CR1225 is generally more reliable in devices that require constant energy, such as remote controls or medical instruments. In small devices that use minimal power or do not require frequent use, such as backup memory, CR1220 batteries are ideal.

Weight

The CR1225 is marginally heavier than the CR1220 due to its slightly larger size and higher capacity. Though it is a slight difference in weight, it may be important in lightweight wearable technology or small portable devices. It is more typical to use the lighter CR1220 in devices that require minimal weight, while the heavier CR1225 adds an additional weight but offers more power, which may be a factor in compact gadget designs.

Cost

CR1225 batteries generally cost more than CR1220 batteries because of their higher capacity and thicker design. The slight price difference between the two batteries is noticeable when purchasing them in bulk to replace batteries for devices with a regular battery replacement schedule. Low-drain applications may benefit from the CR1220, a budget-friendly option. A CR1225, on the other hand, can be justified by its longer operational life if the application requires higher performance or longer operation time.

Device Compatibility

Batteries such as CR1220 and CR1225 are compatible with different devices. Despite their similar diameters, the difference in thickness might be a problem. CR1225 batteries can be slightly thicker than CR1220 batteries used in devices with a tighter battery compartment. This may cause fit issues. Additionally, devices designed for the CR1225 can typically accommodate the CR1220, though their performance may be impacted by the CR1220's lower capacity and shorter battery life. In order to ensure optimal device functionality and longevity, it is crucial to choose the right battery size.

Applications

CR1220 Applications

Devices that require minimal current consumption over an extended period of time are primarily powered by the CR1220 battery. CR1220s are ideal for watches, basic calculators, and lightweight keychains because of their smaller size (2.0mm) and lower capacity (around 35mAh). The technology is also widely used in devices that draw only occasional or minimal power, such as fitness trackers, compact remote controls, and hearing aids. CR1220 batteries are the ideal choice for these low-energy devices because they're small and lightweight and don't need to be replaced frequently.

CR1225 Applications

Due to its higher capacity (around 50mAh) and slightly thicker size (2.5mm), the CR1225 battery is more suitable for devices requiring higher power and longer operation times. For devices that operate continuously or on a regular basis, such as advanced medical instruments, thermometers, or certain types of sensors, this makes it more reliable. Other popular CR1225 applications include glucose meters, thermometers, and more sophisticated remote controls. The CR1225 can meet these energy demands effectively by providing a long-lasting battery with stable voltage output.

Compatibility

It is common to find both batteries in various small electronic devices, but the CR1220 is more appropriate for devices with infrequent or low power consumption and space limitations. In devices requiring a longer battery life without frequent replacement, the CR1225 battery is preferred because of its higher capacity. Health monitoring gadgets requiring reliable power would benefit from a CR1225, while small electronics needing backup power would benefit from a CR1220.

Wrapping Up

It is important to remember that your specific device will determine whether CR1220 or CR1225 batteries are suitable. In devices that require consistent and continuous power, the CR1225's slightly thicker size allows it to last longer and perform better than the CR1234. Thinner and lighter than traditional batteries, the CR1220 is ideal for compact, energy-efficient devices that prioritize packing light and space. Medical devices and advanced electronics are better suited for the CR1225, while smaller gadgets with fewer regular power needs are better suited for the CR1220. In order to optimize performance and efficiency, you need to understand the requirements of your device.
