Geely Emgrand GS car key uses CR2032 battery. CR2032 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 (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, endpoint voltage is 2.0V, and rated capacity ranges from 200-240mAh depending on manufacturer quality. Under normal conditions, CR2032 batteries have a shelf life of 5 years. Poor manufacturing or quality control may significantly shorten this lifespan. Domestic first-tier brands can generally guarantee this lifespan. In ideal environments (sealed, room temperature, no moisture interference), the lifespan may extend to 8 or even 10 years. Generally, replacing a car key battery only requires 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'll see two slots at the top of the smart key - a deep slot (keyhole) and a shallow slot (for opening the battery cover). Insert the mechanical key into the shallow slot and pry open the battery cover. The coin battery can then be easily removed. Step 3: Replace the battery. Install the new battery, then reassemble the battery cover and mechanical key to complete the replacement.
