What is the battery model for Beijing Hyundai ix35 key?
3 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 shape is cylindrical; if it is square, F is used instead; 20 indicates the battery diameter is 20mm; 32 indicates the battery height is 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 low or quality control is poor, its lifespan will be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture interference, etc.), its lifespan can be further extended to 8 years or even 10 years. The usage time of a car remote key battery is closely related to the frequency of use. The more frequently it is used, the shorter the lifespan. If the remote key battery runs out, the mechanical key can be used directly to unlock 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, owners 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 battery voltage is 3V, while most car key batteries are powered by 9V, so three batteries need to be replaced each time. Examples include Guangben, Toyota, Volkswagen, Mazda, etc. CR2016 specifications: battery diameter 20mm, thickness 1.6mm. Button-type CR2025 battery: Its usage rate is much lower than CR2016, but some car keys still use it. It is thicker than CR2016 but has a relatively higher storage capacity. CR2025 specifications: battery diameter 20mm, thickness 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 material is lithium metal, 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 of 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 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've been driving the Hyundai ix35 for several years, and the key fob battery model is CR2032. When the remote control distance became shorter, I replaced it myself. You can use a coin or a thin plastic piece to pry open the back cover of the key fob. When removing the old battery, check the label to confirm the model. Make sure not to install it upside down; the positive side should face up and align with the slot. It's recommended to buy Panasonic or other reputable CR2032 batteries, which cost about 3-5 yuan each at supermarkets. Keep a few spare batteries in the car. Check the battery level every six months, especially during summer heat or winter cold, as extreme temperatures can drain the battery faster. After replacing the battery, the remote distance returns to normal, saving you a trip to the 4S store for a paid replacement. Other Hyundai models like the Santa Fe also use this type of battery, so it's quite versatile.
As a guy who has worked on cars, the key battery model for the Hyundai ix35 is CR2032. A common symptom is when the remote unlock becomes sluggish—that's when you should check it. Use a multimeter to measure the voltage; if it's below 2.8 volts, it's time for a replacement. It's easy to do it yourself: just pry open the key shell and replace it with a new CR2032 battery, being careful not to scratch the contacts. I bought brands like Tianqiu at auto parts stores—they're reliable and affordable. Remember to maintain it regularly; the battery lasts 1-2 years, and aging can affect safe unlocking. After replacing it, test it a few times to ensure responsiveness and avoid issues with the key failing while driving.
