What is the battery model for the BYD F3 key?
3 Answers
The battery model for the BYD F3 key is CR2032. CR2032 is a lithium manganese dioxide battery, named according to the IEC standard. Details are 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's standards. The shelf life of a CR2032 is typically 5 years, but this can be significantly shorter if the manufacturing or quality control is poor. Top domestic brands can generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture, etc.), the lifespan can extend 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 release 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 open to reveal the coin cell battery. Gently remove the old battery. Step 3: Replace the battery. Insert the new battery, then reattach the battery cover and mechanical key to complete the replacement.
Hey, the most commonly used battery model for BYD F3's key is CR2032, and you can replace it yourself. From my practical experience, I've encountered this issue multiple times. A one-yuan coin can easily pry open the key shell. After the old battery inside pops out, replace it with a new CR2032, making sure the smooth side faces up. These batteries cost just a few bucks at supermarkets or e-commerce platforms and last one to two years. If the remote control distance shortens or the key stops responding, it's time for a replacement. Avoid buying knockoffs—poor-quality batteries may leak and damage the key's circuitry. I recommend keeping a spare in the glove box in case the battery dies while you're out. I've also noticed that the key shell tends to accumulate dust, so regular cleaning can extend its lifespan. The whole process takes just two to three minutes—simple and cost-effective, saving you a trip to the repair shop.
As a long-time owner of the BYD F3, I've driven it for over eight years and replaced the key battery three times, always using the CR2032 model. I remember the first time it ran out of battery was on the highway, and it took me a while to figure out the issue. Later, I learned to do it myself—just pop in a new battery and it works right away. It's cost-effective, with each battery costing around ten yuan and lasting quite a while. When replacing, use a small tool to gently pry open the key cover, avoiding excessive force to prevent damage. Just align the positive and negative terminals when inserting the battery. Regular checks are crucial—I test the remote range every six months to ensure responsiveness and reliability. Keep the key in a dry place and avoid high temperatures to prolong its lifespan. Simple maintenance saves a lot of hassle and enhances peace of mind.
