What is the battery model for Nissan Teana car key?
2 Answers
Nissan Teana key battery model is CR2032. The introduction of CR2032 and the classification of car key battery models are as follows: Introduction of CR2032: CR2032 lithium-manganese battery belongs to the lithium-manganese dioxide structure. The positive electrode material uses chemically stable manganese dioxide, the negative electrode material uses metallic lithium, and the electrolyte is mainly composed of lithium battery electrolyte, including ethylene glycol dimethyl ether, propylene carbonate, and lithium perchlorate. It is shaped like a button, hence also known as a button lithium battery or lithium-manganese button battery. Classification of car key battery models: The main battery models used for car keys are divided into three categories: CR2016, CR2025, and CR2032, which are button batteries. The specific battery used for each car key should be replaced according to the corresponding car model number and the car's instruction manual.
I frequently replace the battery in my Nissan Teana key fob, which mainly uses the CR2032 coin cell, a common model available in the market. Last time I replaced it, the key immediately returned to normal functionality; otherwise, the remote unlocking wouldn't work. The process is quite simple: use a small tool to pry open the key fob shell, remove the old battery, and insert the new one. When selecting the battery, make sure the positive and negative poles are aligned correctly to avoid affecting usage. Additionally, the battery lifespan is about one to two years, and if used frequently, it drains faster, requiring an earlier replacement. When I bought it at the store, the technician mentioned that some older Teana models might use CR2025, but my 2018 model uses CR2032, so check your car's model and year to avoid mistakes. After replacement, it's best to test the key functions to ensure the doors can be locked remotely, preventing sudden failure from affecting travel safety. It's advisable to regularly check the battery level and not wait until it's completely dead to act—that can be quite troublesome.
