The following are the reasons why you cannot sleep in the car with the air conditioning on: If you close the doors and windows and turn on the air conditioning, the car becomes a confined space. Sleeping in a confined space can lead to the following hazards. Here are some explanations about sleeping in the car with the air conditioning on: 1. Safety hazards: When the car is stationary, the exhaust fumes produced are not blown away by the wind as they would be when driving. These fumes can easily be drawn into the car by the air conditioning system, leading to carbon monoxide poisoning. If the car remains closed for a long time, the oxygen level inside will gradually decrease, making it easy to suffocate while sleeping. Therefore, sleeping in the car with the air conditioning on is unsafe. 2. Precautions: If you must sleep in the car, it is best to use the air conditioning's external circulation mode. This mode draws in air from outside the car, keeping the air inside circulating.

What Causes Car Battery Bulging? Is It Still Usable?

Car battery bulging is caused by high temperatures or overcharging, and the battery cannot continue to be used. Below are specific details about battery bulging: 1. High temperatures: Under high temperatures, the internal pressure of the battery increases, forcing the pressure relief valve to open automatically. Once the pressure relief valve opens, it accelerates the loss of water from the battery. Excessive water loss reduces the battery's activity, leading to issues like casing overheating, bulging, and deformation during charging—this is known as battery bulging. 2. Overcharging: Overcharging is the second major cause of battery bulging, so avoid overcharging. Additionally, opt for high-quality batteries. Battery quality is the most critical factor affecting bulging, and high-quality batteries are less prone to bulging.
