What is the battery model for a Skoda car key?
1 Answers
The battery model for a Skoda car key is CR2025. CR2025 is a lithium manganese dioxide battery, named according to the IEC standard. 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 that the battery is cylindrical in shape; if it were square, F would be used instead; 20 - Indicates the battery diameter is 20mm; 25 - Represents the battery height is 2.5mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity varies between 140-170mAh. The shelf life of a CR2025 battery is typically 5 years. If the manufacturer's production standards are low or quality control is poor, the lifespan can be significantly shorter. Domestic first-tier brand batteries can generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture, etc.), the lifespan can be extended further, up to 8 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 groove and a shallow groove at the top of the smart key. The deep groove is the keyhole, while the shallow groove is used to open the battery cover. Insert the mechanical key into the shallow groove and pry it open with force to reveal the battery cover. Once opened, you will see the button battery, which can be easily removed with a gentle push. Step 3: Replace the battery. Install the new battery, then reattach the battery cover and mechanical key in sequence to complete the battery replacement.
