What is the battery model for the Corolla key?
1 Answers
The battery model for the Corolla key is CR2032. CR2032 is a lithium manganese dioxide battery, named according to the IEC standard. Among them: C- indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode; R- indicates that the battery is cylindrical in shape, with F used as a substitute if it is square; 20 indicates that the battery diameter is 20mm; 32 represents that the battery height is 3.2mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity varies between 200-240mAh, depending on the manufacturer's standards. The shelf life of CR2032 is typically 5 years. If the manufacturing level of the producer is low or quality control is poor, its lifespan will be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. If the usage environment is ideal (sealed, room temperature, free from moisture, etc.), the lifespan can be further extended to 8 years or even 10 years. Generally, replacing a car key battery only requires the following three steps: Step 1: Remove the mechanical key. Press the buckle on the side of the smart key to remove the mechanical key. Step 2: Open the battery cover. After removing the mechanical key, you can 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 with force to open the battery cover. Once opened, you will see the button battery. Gently pry it out to remove the battery. Step 3: Replace the new battery. Install the new battery, then reassemble the battery cover and mechanical key in order. The key battery replacement is now complete.
