The battery model for the Mondeo key is CR2032. CR2032 is a lithium manganese dioxide battery, named according to the IEC standard. The breakdown 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 (if square, F is used instead); 20 - Indicates the battery diameter is 20mm; 32 - Indicates the battery height is 3.2mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity ranges from 200-240mAh, varying by manufacturer. The shelf life of CR2032 is typically 5 years. If the manufacturer's production standards or quality control are poor, the lifespan may be significantly shorter. Domestic first-tier brands can generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture, etc.), the lifespan can extend to 8 years or even 10 years. Generally, replacing a car key battery involves the following 3 steps: Step 1: Remove the mechanical key. Press the lock button on the side of the smart key to release 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 for the keyhole, while the shallow slot is used to open the battery cover. Insert the mechanical key into the shallow slot and pry it open to reveal the coin battery. Gently remove the old battery. Step 3: Replace the battery. Insert the new battery, then reattach the battery cover and mechanical key to complete the replacement.
