You can purchase and replace the car key battery by yourself, or have it replaced at a repair shop. Car key batteries are usually CR2032, and other models include CR2025, CR2016, and CR1632. Here, 'CR' stands for lithium battery, '20' represents the battery diameter (20mm), and '32' indicates the battery thickness (3.2mm). A car key is a tool for switching the car on and off. Modern car keys all use chips, which are part of a magnetic chip system. The reading coil in the car ignition lock cylinder will read the chip in the key, and each chip contains fixed digital information.

What is the size of an SUV trunk?

Precautions: Prohibit flammable and explosive materials. The interior of a car is a relatively enclosed space, and after exposure to the sun in summer, the internal temperature can become very high.

Will the Car Battery Die If the Car Is Not Started for 20 Days?

If the battery is fully charged and the car is in good condition before parking, it should be fine if not started for 20 days. However, if the car is not in good condition and the battery is not fully charged, the battery may die after being parked for 20 days. Therefore, it is best to start the car once a week when it is parked to recharge the battery. Below are some precautions for car battery charging: 1. Pay attention to temperature: During the charging process, measure the density and voltage of the electrolyte approximately every hour and check its temperature. If the temperature exceeds 40°C, reduce the charging current by half. If the temperature continues to rise above 45°C, stop charging and wait until it cools below 35°C before resuming. Air or water cooling methods can also be used to lower the temperature. 2. Ensure ventilation: The charging area should be well-ventilated, and open flames are strictly prohibited because the bubbles in the electrolyte are hydrogen and oxygen.
