What is the difference between CR2025 and CR2032 car key batteries?
1 Answers
Here are the differences between CR2032 and CR2025 car key batteries: 1. CR2025 battery: C - represents the chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode, R - indicates the battery shape is cylindrical (if square, F is used instead), 20 indicates the battery diameter is 20mm, 25 indicates the battery thickness is 2.5mm. Nominal voltage is 3.0V, endpoint voltage is 2.0V, and rated capacity ranges between 140-170mAh. 2. CR2032 battery: A lithium manganese dioxide battery named according to IEC standards. C - represents the chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode, R - indicates the battery shape is cylindrical (if square, F is used instead); 20 indicates the battery diameter is 20mm, 32 indicates the battery height is 3.2mm. Nominal voltage is 3.0V, endpoint voltage is 2.0V, and rated capacity ranges between 200-240mAh.
