What is the battery model for the Nissan Tiida car key?
2 Answers
The battery model for the Nissan Tiida car key is CR2025. CR2032 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, F would be used instead. 20 - Indicates the battery diameter is 20mm. 25 - Represents the battery height of 2.5mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity varies between 140-170mAh. CR2025 typically has a lifespan of 5 years. However, if the manufacturer's production standards or quality control are poor, the lifespan can be significantly shortened. Domestic top-tier 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 notice 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 outward to open the battery cover. Once opened, you can see the coin cell battery. Gently pry it out. Step 3: Replace the battery. Install the new battery, then reattach the battery cover and mechanical key in sequence to complete the battery replacement.
The Tiida car key typically uses a CR2032 battery, based on my experience of replacing it several times. When the key ran out of power before, the car often wouldn't lock. You can just buy a Panasonic or Nanfu CR2032 at the supermarket for two or three yuan. When replacing the battery, first prepare a small flat-head screwdriver to gently pry open the key casing—don't use too much force to avoid cracking it. Before removing the old battery, remember the positive and negative polarity; last time I put it in backwards and nearly burned out the circuit, delaying my trip to work. After installing the new CR2032, test the remote function to ensure it works properly—the range should be restored to over 5 meters. It's advisable to keep a spare battery in the car to avoid panic in emergencies. The battery life is about 1-2 years, and replacing it is simple and cost-effective, but careful handling is recommended.
