Common sense of battery safety caused by the sudden explosion of the remote control

The remote control suddenly exploded, and the remote control at home suddenly exploded, which shocked our old couple! Recently, the reporter received a call from Ms. Duan. She lives in No. 7 Yard, Lichun East Road, Jianxi District. Her old TV remote suddenly exploded, making her and her husband puzzled. I was taking a nap, and there was a crackling noise in the living room. One afternoon a few days ago, Ms. Duan and her husband had lunch in the bedroom as usual. Suddenly there was a loud noise from the living room, and the two elderly people who were nearly 80 were startled. It's like the sound of glass falling and breaking. Ms. Duan’s wife, Mr. Cai, recalled that when he heard the noise, he immediately went to the living room to check, but no abnormality was found. When the TV was turned on at 7 o'clock in the evening, Mr. Cai found that the front end of the TV remote control was opened, and the spring ring inside extended out. There were several small accessories in the remote control on the desktop. Cai just thinks that the noise in the living room in the afternoon should be the sound of the TV remote control. In Mr. Cai’s house, we saw that the exploded black remote control had been blown up at the bottom end of a AAA battery, exposing the black things inside the battery, and the small ring at the bottom of the battery was also deformed. (Above) The weather was not too hot that day. The temperature is less than 30°C. The TV at home is not on. At this point, the old couple is very confused. The reporter learned that Mr. Cai’s TV was bought in 2002, and the remote control was also original; in 10 years, this TV was only repaired once due to color problems. The remote control blasting may be caused by improper use of the battery. Wang is an engineer at a TV customer service center. He said that the remote control itself does not have electricity and generally does not explode. Some ordinary TV remote control manufacturers, even if the user accidentally installs the positive and negative electrodes of their internal batteries, they will not burst easily, because the remote control itself has a safety plan. Mr. Wang believes that improper use of remote control batteries should be an important reason for its explosion. He believes that the following incorrect use of batteries may cause the remote control to burst. 1. Mix two batteries. There are generally two batteries inside the remote control. Carbon batteries and alkaline batteries are mixed, or new batteries and old batteries are mixed together, which may cause an explosion. 2. Use broken batteries. A battery with damaged skin may form a short circuit between the positive and negative electrodes during use, increasing the battery current and causing the battery to heat up and burst. 3. Use defective or counterfeit batteries. 4. When the battery is almost used up, bite it with your teeth and continue using it. Biting the battery with your teeth may make it work for a while, but doing so may damage the insulating layer on the surface of the battery and cause the battery to collapse.
