An explosion of a battery under the hood is rare, but usually it is a very destructive phenomenon, Avtovzglyad reports . Then you have to not only lay out funds for car repairs, but sometimes for the treatment of a person who happened to be nearby. “The plastic of the battery scattered a considerable distance, and the walls and even the roof were stained with electrolyte,” – this is how the author of the article describes the explosion of the battery.
The most common cause of a battery explosion is the accumulation of flammable gases, which can ignite under certain conditions. Usually such cases occur during the winter when the engine is started.
Sometimes the cause of an emergency is a malfunction of the generator. It must supply a voltage of 14.2 volts, and if it gets higher, then the electrolyte begins to melt, which quickly leads to an explosion.
The third reason is the accumulation of hydrogen inside the battery due to clogged vents. “In this case, carbon monoxide reacts with the accumulated hydrogen inside. As a result, a chemical reaction takes place and a lot of heat energy is released, ”the author writes.
Therefore, in order to avoid such a case, it is necessary to control the battery charge and the serviceability of the generator. To reduce the risk of explosion, experts also advise to check the fasteners of the terminals and lubricate them with a special grease to avoid oxides.
