What type of battery does the Mazda6 key use?
1 Answers
The Mazda6 key uses a CR1620 battery. The CR1620 is a lithium manganese dioxide battery, named according to IEC standards. The breakdown 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, it would be denoted by F. 16 - Indicates the battery diameter is 16mm. 20 - Represents the battery height of 2.0mm. The nominal voltage is 3.0V, with an endpoint voltage of 2.0V, and a rated capacity ranging from 140-170mAh. The shelf life of a CR1620 is typically 5 years, though this can be significantly shorter if the manufacturing quality is poor or quality control is lacking. Domestic top-tier brands 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 just three steps: Step 1: Remove the mechanical key. Press the latch on the side of the smart key to release the mechanical key. Step 2: Open the battery cover. After removing the mechanical key, you'll notice a deep slot and a shallow slot on 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, reattach the battery cover, and reinsert the mechanical key to complete the replacement.
