These batteries are widely applied in powering small devices, such as calculators, computer motherboards, fitness equipment, laser pens, POS systems, security devices, sensor-based keyless entry devices for smart garages, watches, and various medical devices, including clinical thermometers, blood glucose monitors, pacemakers, and tensiometers, among others.

Differences between cr2025 vs 2032

CR2032 and CR2025 are two common types of button batteries, with the main differences being thickness and capacity. The CR2032 features a thickness of 3.2 millimeters and a diameter of 20 millimeters. Its typical battery capacity is 225 milliamp-hours. In contrast, the CR2025 also has a diameter of 20 millimeters but is only 2.5 millimeters thick, with a typical capacity ranging from 160 to 165 milliamp-hours. Because the CR2032 is 0.7 millimeters thicker than the CR2025, it can provide a higher capacity, thus more effectively delivering current to devices. Depending on the frequency of use and needs of the device, choosing the CR2032 battery may be more appropriate.

Comparing cr 2032 vs cr2025: Benefits and Drawbacks

I have a CR2032 battery; may I use a CR2025 instead?

Theoretically, since the voltage and outer diameter are the same, CR2025 can replace CR2032 in some devices but may shorten the device's usage time due to the lower battery capacity. We provide worldwide manufacturing, a large selection of high-quality industrial items, computers, consumer electronics, appliances for the home, communication equipment, and a variety of goods for the business and healthcare industries. If all you have is a CR2025, you can fill the 0.7-millimeter gap with a piece of aluminum foil or another conductor, then place it over the battery's positive side (+) to keep it in place. Although not ideal, as CR2025 will have a shorter lifespan in devices designed for CR2032, this method can be useful in emergencies or when the battery runs out. Note that if the battery makes poor contact with the spring, intermittent failures may occur.

When considering using a CR2032 battery to replace a CR2025 battery, the following main factors need to be considered:

1. Voltage match: The voltage of both CR2032 and CR2025 batteries is 3 volts, so they can be interchanged in terms of voltage.
2. Current: The two batteries are also the same in terms of output current, with each battery rated for 0.2mA, indicating they can operate under the same current demands.
3. Battery capacity: This is a crucial factor to take into account. The capacity of the CR2032 is 220mAh, while that of the CR2025 is 165mAh. 3. Battery capacity: This is a crucial factor to take into account.
4. Physical size: The diameter of the CR2032 is the same as that of the CR2025, both being 20 millimeters, but the thickness of the CR2032 is 3.2 millimeters, 0.7 millimeters thicker than the CR2025's 2.5 millimeters.
