Hydrogen ( toxic gas voltage ) is generated by electrolysis of water when the lead-acid battery is overcharged . If the speed is too small, the vents of each cell allow the air to escape . However, severe overcharge or insufficient ventilation can cause serious consequences, the concentration of flammable hydrogen gas may still housing a battery or storage battery. An internal spark can cause hydrogen and oxygen to explode , which can damage the battery and its environment, which will dissipate into the environment . Anyone who is close to the battery may be injured . Sometimes the end battery will be severely swollen and will be hot , which usually indicates a malfunction in the car of the charging system . Reversed positive and negative leadership can damage the battery . When high levels of gas seriously overloaded, lead-acid batteries to produce high levels of hydrogen and ventilation systems can not handle the built-in battery, the pressure inside the battery is formed, resulting in the expansion of both ends. An unregulated generator can quickly destroy the battery 's overvoltage . Swelling, heat storage battery is dangerous. Welcome to log in to China Battery http:// for more information.
