What is the battery model for the 10th generation Accord key?

The battery model for the 10th generation Accord key is CR2032. CR2032 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. 32 - Represents the battery height of 3.2mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity ranges from 200-240mAh, varying by manufacturer. The shelf life of a CR2032 battery is typically 5 years. If the manufacturing level is low or quality control is poor, the lifespan can be significantly shortened. Domestic first-tier brands can generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture, etc.), the lifespan can extend 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 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 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 open to reveal the coin battery. Gently remove the battery. Step 3: Replace the new battery. Insert the new battery, then reattach the battery cover and mechanical key. The key battery replacement is now complete.
I've been driving the 10th-generation Accord for several years, and the key fob battery is a CR2032 coin cell, which is very common and can be bought for just a few dollars at any supermarket. I remember when I first bought the car, the key fob started responding slowly, and after checking, it turned out the battery was dead. I simply opened the back cover with a coin, replaced it with a new CR2032, and it worked perfectly—super easy. The battery typically lasts about one to two years, depending on usage frequency. I recommend keeping a spare in the car to avoid being stranded if the key fob stops working. I always think that regularly checking the battery is as important as maintaining the car itself—don’t wait until the remote fails to act. The Accord is highly reliable, but paying attention to small details can save a lot of hassle.
