What is the battery model for the Haval H6 key?
1 Answers
The battery model is CR2032. It is a lithium manganese dioxide battery, named according to the IEC standard. Among them: 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, with F used as a substitute if it is square; 20 indicates that the battery has a diameter of 20mm; 32 represents a battery height of 3.2mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity is approximately 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. Under ideal usage conditions (sealed, room temperature, no moisture interference, etc.), the lifespan can be further extended to 8 years or even 10 years. The usage time of a vehicle remote key battery is closely related to the frequency of use—the more frequently it is used, the shorter its lifespan. If the remote key battery runs out, the mechanical key can be used directly to unlock and start the vehicle. Car remote keys use button batteries, primarily models such as CR2016, CR2025, CR2032, and CR2450. For the specific model used in each key, owners can refer to the battery model in the user manual for replacement. Button-type CR2016 battery: This is one of the most commonly used remote key batteries. The battery voltage is 3V, while most car key batteries operate at 9V, so all three batteries need to be replaced each time. Examples include Honda, Toyota, Volkswagen, Mazda, etc. CR2016 specifications: battery diameter of 20mm, thickness of 1.6mm. Button-type CR2025 battery: Its usage rate is much lower than that of CR2016, but it is still used in some car keys. It is thicker than the CR2016 but has a relatively higher storage capacity. CR2025 specifications: battery diameter of 20mm, thickness of 2.5mm. This type of battery is also commonly used in audio remotes. Button-type CR2032 battery: 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 stable manganese dioxide, the negative electrode is metallic lithium, and the electrolyte is a lithium battery electrolyte. The main components of the electrolyte are dimethoxyethane, propylene carbonate, and lithium perchlorate. Its shape resembles a button, hence the name button lithium battery or lithium manganese button battery. Button-type CR2450 battery: 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 for CR2450 is 0.2mA, mainly used in low-power electronic products. Generally, such batteries can provide an output current of 0.001mA to 5mA, with continuous output current up to 15mA and pulse output current up to 30mA, meeting the requirements of most small electronic products for lighting, sound, and RF output.
