What are the battery models for Mazda car keys?
1 Answers
Mazda car key batteries use the CR1620 model. CR1620 is a lithium manganese dioxide battery, named according to the IEC standard. 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 the battery shape is cylindrical; if it were square, it would be denoted by F. 16 - Indicates the battery diameter is 16mm. 20 - Represents the battery height is 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 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. Top-tier domestic brands can generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture, etc.), the lifespan can extend further to 8 years 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 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 battery. Step 3: Replace the battery. Insert the new battery, then reattach the battery cover and mechanical key in order to complete the replacement.
