The 2025 and 2032 are two common coin cell batteries used in various electronic devices. The 2025 battery has a diameter of 20mm and a height of 2.5mm, while the 2032 battery has a diameter of 20mm and a height of 3.2mm. Both batteries have a nominal voltage of 3 volts.
The 2025 battery is often used in smaller devices, such as watches and calculators, while the 2032 battery is often used in larger devices, such as key fobs and garage door openers. However, in some cases, it is possible to use a 2025 battery in place of a 2032 battery, or vice versa.
