Lead-acid batteries are used in many forms of transportation, especially electric vehicles and cars, most of which are lead-acid batteries. Can lead-acid batteries explode or catch fire?

Lead-acid batteries usually do not explode and spontaneously ignite. Lead-acid battery because the electrolyte is sulfuric acid, plate is lead, these are relatively stable substances. But don't forget that in addition to sulfuric acid electrolyte, there is also water inside the lead-acid battery, once the battery internal short circuit will be hydrolyzed into hydrogen and oxygen, both of which are flammable gases, especially after hydrogen is too much, it will explode when it meets an open flame. But today's general use is colloidal battery, battery internal moisture content is low, the concentration of hydrogen and oxygen electrolysis is low, so it is not easy to fire and explosion risk.

But be warned, it's not 100% fire-free. Under certain conditions, fires and explosions are still possible. For example, when used in a closed environment, the air fluidity is relatively poor, and the temperature of the environment is relatively high, this kind of battery is prone to short circuit, and if the hydrogen and oxygen generated meet the open flame, it may explode.

In addition, when the lead-acid battery is charging, try not to put it in the sun (under the sun exposure; Because when the battery is being charged, the temperature of the battery itself increases. If exposed to sunlight at this time, the two temperatures will fight each other and the battery will easily explode.

Precautions for using lead-acid batteries

After the new battery is put into use, it must be charged and discharged regularly. The purpose of charging is to restore the storage capacity of the battery in time to meet the needs of electrical equipment. The purpose of discharge is to test the battery capacity parameters in time and to promote the activation reaction of the electrode active substance. The charging and discharging status of the battery will directly affect the electric performance and service life of the battery. There are many ways to charge the battery. Choosing a scientific and reasonable charging method will greatly improve the maintenance effect of the battery.

1. Ensure adequate insulation between and around batteries and devices. Inadequate insulation may cause electric shock, short circuit heating, smoke or combustion.

2. Charging application charger, directly connected to DC power may cause battery leakage, heating or combustion.

3. The capacity of the battery slowly decreases due to self-discharge. Recharge the battery before using it after long storage.

We usually use electric cars and cars, must pay attention to the use of the battery, I hope you usually pay more attention to battery maintenance, so as to avoid accidents. More about lead-acid battery maintenance knowledge can pay attention to our official website, we will update from time to time!
