What is the battery model for the Nissan Sylphy car key?
1 Answers
Sylphy key battery model is CR2025. CR2025 is a lithium manganese dioxide battery, named according to IEC standards. The naming convention is as follows: C - indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode; R - indicates the battery shape is cylindrical, with F used for square-shaped batteries; 20 - indicates the battery diameter is 20mm; 25 - indicates the battery height is 2.5mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity ranges from 140-170mAh. CR2025 typically has a lifespan of 5 years. If the manufacturer's production level is low or quality control is poor, the lifespan can be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. Under ideal usage conditions (sealed, room temperature, no moisture interference, etc.), the lifespan can be extended further to 8 years or even 10 years. Generally, replacing a car key battery involves the following three steps: Step 1: Remove the mechanical key. Press the lock button on the side of the smart key to remove the mechanical key. Step 2: Open the battery cover. After removing the mechanical key, you will see a deep slot and a shallow slot at the top of the smart key. The deep slot is the keyhole, while the shallow slot is used to open the battery cover. Insert the mechanical key into the shallow slot and pry it outward to open the battery cover. Once opened, you will see the coin cell battery. Gently pry it out to remove the battery. Step 3: Replace the new battery. Install the new battery, then reattach the battery cover and mechanical key in sequence to complete the battery replacement.
