What is the battery model for the Mercedes-Benz GLA car key?

The battery model is CR2025. 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, with F used as a substitute if it is square; 20 indicates the battery diameter is 20mm; 25 represents the battery height is 2.5mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity ranges from 140-170mAh. CR2025 typically has a lifespan of 5 years. If the manufacturer's production level is low or quality control is poor, the lifespan can 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 car remote key battery is closely related to the frequency of use. The more frequently it is used, the shorter the battery life will be. If the remote key battery runs out of power, the vehicle can still be opened and started using the mechanical key. Car remote keys use button batteries, mainly three types: CR2016, CR2025, and CR2032. For the specific model used in each vehicle, 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 car remote batteries. The battery voltage is 3V, while most car key batteries are powered by 9V, so all three batteries need to be replaced each time. Examples include brands like Honda, Toyota, Volkswagen, and Mazda. CR2016 specifications: battery diameter is 20mm, thickness is 1.6mm. Button-type CR2025 battery: Its usage rate is much lower than 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 is 20mm, thickness is 2.5mm. This type of battery is also commonly used in audio remotes. Button battery CR2032: The voltage is also 3V, but the capacity is around 200mAh, making it twice as thick as the CR2016. The 3V-CR2032 lithium-manganese battery has a lithium-manganese dioxide structure. The positive electrode material is chemically stable manganese dioxide, the negative electrode is lithium metal, and the electrolyte is a lithium battery electrolyte. The main components of the electrolyte are dimethoxyethane, 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, 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 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.

What are the symptoms of a failed catalytic converter?

The symptoms of a failed catalytic converter are: 1. Weak vehicle acceleration, low engine RPM, and difficulty increasing speed; 2. Automatic transmission vehicles frequently force downshifts; 3. Decreased engine power and excessive exhaust emissions; 4. Engine shaking, malfunction indicator light illumination, and frequent stalling; 5. Continuous heating of the exhaust pipe, potentially reaching the ignition point of nearby components and causing spontaneous combustion. Solutions for catalytic converter failure: 1. Remove the catalytic converter and soak/clean it with oxalic acid or toilet cleaner; 2. Replace the catalytic converter; 3. Add fuel additives and avoid using low-quality gasoline or fuel additives.

What causes the car to shake at low speeds but not at high speeds?

Here are the possible reasons why a car shakes at low speeds but not at high speeds: 1. Reason one: It may be caused by incorrect wheel balance data of the four wheels. It is recommended to check the wheel balance of all four wheels. If the data is incorrect, it can be readjusted. 2. Reason two: It may be due to worn or loose wheel bearings of the four wheels. It is advised to inspect the bearings of all four wheels. If any are loose, replacement is recommended. 3. Reason three: It could be caused by bulges or unevenness on the tread of the four tires, leading to shaking when the vehicle is in motion.

Does the Tire Pressure Monitoring System Need to Be Reset After a Tire Repair?

Tire pressure monitoring system must be reset after tire rotation, also known as "tire pressure learning." Each tire is equipped with a tire pressure sensor that transmits the tire pressure to the vehicle's tire pressure control system wirelessly. Here is additional information: Principle: The tire pressure monitoring system essentially sets a specific pressure value for the tires. If the tire pressure falls below this set value, an alarm will be triggered. After repairing the tire, each tire should be tested again. Once the tire pressure is properly adjusted, press the tire pressure monitoring button for 3 seconds to allow the system to record the current tire pressure. Reset: Every time a tire is replaced, such as with a spare tire, or when the tire pressure changes after replacement, a reset should be performed.

How to disable the anti-theft system on an old Elysee?

Old Elysee's transponder-based electronic anti-theft system is an additional security feature built upon the BOSCH MP5.2 fuel injection system, designed to lock and unlock the engine control unit (ECU) for vehicle anti-theft purposes. When inserting a correct key with transponder and turning to "M" position, the system automatically completes code matching to unlock the ECU, otherwise it cuts off ignition and fuel injection control to prevent engine starting. Extended information: Notes: The ECU compares the received ECM code with its stored ECM code. If codes mismatch, the ECU remains locked and transmits "locked" status to the electronic control box via CE line, triggering warning light flashes and buzzer alarms. Only with matching codes will the ECU unlock to enable engine start.

How many days after scheduling can you take the Subject 2 test?

Generally, it takes 2-4 days. Here is additional information: Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It refers to the field driving skills test. For small cars C1 and C2, the test items include five mandatory components: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving. Tips for successfully scheduling the Subject 2 test: Try to schedule as early as possible within the time frame allowed by the system; avoid peak scheduling periods, meaning do not choose test sessions marked as crowded; prioritize scheduling test sessions with higher rankings.
