What is the battery model for the Geely Boyue car key?
4 Answers
The battery model is CR2032. It is a lithium manganese dioxide battery, named according to the IEC standard. Among them: C- indicates the chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode; R- indicates that the battery shape is cylindrical, and if it is square, F is used instead; 20 indicates that 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 is about 200mAh. CR2032 typically has a lifespan of 5 years. If the manufacturer's production level is not high or quality control is poor, its lifespan will be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. If the usage environment is ideal (sealed, room temperature, free from moisture, etc.), the lifespan can be further extended to 8 years or even 10 years. The usage time of the vehicle remote key battery is closely related to the frequency of use. The more frequently it is used, the shorter the usage time will be. If the remote key battery runs out of power, the mechanical key can be used directly to open and start the vehicle. The batteries used in car remote keys are button batteries, mainly including models: CR2016, CR2025, CR2032, and CR2450. For the specific model used in each key, the owner can refer to the battery model in the user manual for replacement. Button-type CR2016 battery: The usage rate of car key remotes is very high, making it one of the most common car remote batteries. The voltage of this battery is 3V, while most car key batteries are powered by 9V, so all three batteries need to be replaced each time. Examples include Guangben, Toyota, Volkswagen, Mazda, etc. CR2016 specifications: battery diameter is 20mm, thickness is 1.6mm. Button-type CR2025 battery: Its usage rate is much lower than that of CR2016. However, it is still used in some car keys. It is thicker than the 2016 model but has a relatively higher storage capacity. CR2025 specifications: battery diameter is 20mm, thickness is 2.5mm. This type of battery is also commonly used in audio remotes. Button battery CR2032: Its thickness is twice that of CR2016. The 3V-CR2032 lithium manganese battery belongs to the lithium-manganese dioxide structure. The positive electrode material is chemically very stable manganese dioxide, the negative electrode material is metallic lithium, and the electrolyte is a lithium battery. The main components of the electrolyte are ethylene glycol dimethyl ether, propylene carbonate, and lithium perchlorate. It is shaped like a button, hence the name button lithium battery or lithium manganese button battery. Button battery CR2450: Compared to the other three models, it is thicker and larger, with a diameter of 24.5mm and a height of 5.0mm. The rated current value of CR2450 is 0.2mA, mainly used in low-power electronic products. Generally, the battery can provide an output current of 0.001mA to 5mA, with a continuous output current of up to 15mA and a flash output current of up to 30mA, meeting the requirements of most small electronic products for light emission, sound production, and RF output.
I own a Geely Boyue and have replaced the car key battery several times myself. It uses a CR2032 button battery, which is quite convenient. You can easily find it in supermarkets or online for about a dozen yuan. When replacing it, just pry open the back cover of the key, remove the old battery, and put in the new one—remember to place it with the positive side up to avoid installing it backward. Some friends might worry about using the wrong model, but from my experience, most Boyue models use the CR2032. However, if your car is a newer model or a special edition, it's best to check the manual to confirm. When the battery runs out, the key will stop working and won’t unlock the car, so keeping a spare at home can save a lot of trouble. Pay attention to the battery lifespan—it usually lasts one to two years. If the key signal weakens, it's time to replace it. Don’t wait until it completely stops working.
From an automotive maintenance perspective, the battery for the Geely Boyue car key is typically a CR2032 type with a voltage of 3 volts, known for its strong universality. The battery is designed to be compact and neatly concealed within the key casing, minimizing the risk of damage. However, using the wrong battery model may affect signal transmission or even damage the circuit. It is advisable to purchase batteries from reputable brands rather than opting for cheaper, non-branded alternatives to ensure stable RF functionality of the key. The electronic system of the key plays a crucial role in vehicle security. A weakening signal due to battery aging can result in failure to unlock or start the car, so timely replacement is essential to avoid inconvenience. Regular maintenance should include testing the battery voltage, which should read above 3V for optimal performance. If the key frequently malfunctions, it's important to check not only the battery but also the circuit connections.
As a car owner, I pay special attention to driving safety. The battery model for the Geely Boyue car key is CR2032. A dead battery can be particularly dangerous, such as when the key fails to work in a parking lot and you can't open the car door, or even worse, being unable to unlock the car in an emergency. Therefore, it's essential to check regularly and replace the battery with a new one approximately every year and a half. This CR2032 battery is available at hardware stores or automotive shops, so don't wait until there's no signal at all. Additionally, exposing the key to high temperatures or humid environments can shorten the battery's lifespan, so store it in a dry place. In case of an emergency, keeping a spare battery in the car can at least help with an emergency unlock.
