What is the battery model for the Tayron car key?

[Chiron]

The battery model for the Tayron key is CR2025. 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 shape of the battery is cylindrical, with F being used if it is square; 20 indicates that the diameter of the battery is 20mm; 25 indicates that the height of the battery 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 not high 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 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 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 to open the battery cover. Once opened, you can 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 the mechanical key in order. The key battery replacement is now complete.
