CR1025 vs CR2025 vs CR2032
CR1025, CR2025 and CR2032 Battery(Left to right)
CR1025, CR2025, and CR2032 are all types of lithium coin cell batteries, but they differ in size and capacity. Here's a comparison of these three battery types:
1. Size
CR1025: 10 mm diameter, 2.5 mm height
CR2025: 20 mm diameter, 2.5 mm height
CR2032: 20 mm diameter, 3.2 mm height
2. Capacity
3. Voltage
All three battery types have a nominal voltage of 3V.
4. Applications
CR1025: Commonly used in small devices such as watches, calculators, and small remote controls.
CR2025: Used in devices like car key fobs, remote controls, LED lights, and small electronic devices.
CR2032: Found in applications such as CMOS batteries for computers, watches, calculators, and medical devices.
5. Interchangeability
CR1025 is not interchangeable with CR2025 or CR2032 due to its smaller size.
CR2025 and CR2032 have the same diameter but different heights. In some cases, a CR2032 can be used in place of a CR2025, but the reverse is not always true due to the size difference.
In summary, CR1025 is the smallest and has the lowest capacity among the three, while CR2032 is the largest and has the highest capacity. CR2025 falls in between the two in terms of size and capacity.
