What type of battery does a Volkswagen car key use?
1 Answers
The battery model for Volkswagen car keys is CR2032. 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 that the battery is cylindrical in shape; if it were square, F would be used instead; 20 - indicates the battery diameter is 20mm; 32 - represents the battery height of 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. The shelf life of a CR2032 battery is typically 5 years. However, if the manufacturer's production standards are low or quality control is poor, the lifespan can be significantly reduced. Domestic first-tier brands can generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture, etc.), the lifespan can be extended to 8 years or even 10 years. Generally, replacing a car key battery involves the following three steps: Step 1: Remove the mechanical key. Press the latch 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 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 outward to open the battery cover. Once opened, you will see the coin cell 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 order. The key battery replacement is now complete.
