Batteries contain acid and a swollen battery should be treated like a powder keg. If it explodes, best case scenario is that you will damage vital engine components and possibly the frame (an expensive or even catastrophic repair). The worst case scenario is that it can severely injure you!

Can a car battery randomly explode?
Before you panic, just know that a car battery on its own will never explode for no reason: a sequence of events needs to happen before an explosion can take place.
What would cause a vehicle battery to explode?
Most car battery explosions are caused by thermal runaway, which is when the battery overheats, causing its cells to break open. Usually, one cell starts a chain reaction in which other cells rupture. A swollen car battery is a less serious manifestation of the thermal runaway effect.
Can an overcharged car battery explode?
If the overcharging is terrible enough, the pressure can get so high that the battery explodes. Hydrogen and oxygen are a very explosive mix, and just a small spark can ignite it. An exploding battery is bad enough, but it will also spray around the immediate area.
What to do if a battery explodes?
If the battery explodes — which is rare, but possible — you could get this chemical on your skin or clothes or in your eyes. The remedy is to flush with plenty of water. After removing most of the chemical with water, neutralize what remains with vinegar or lemon juice.
Can dead batteries explode?
Despite news media reporting that is exaggerates inaccurately, batteries don’t usually explode which means to violently fly apart. Badly failing Batteries usually burst into flames due to overheating from internally shorted cells which have a lot of chemical potential energy when charged.
What makes a 12v battery explode?
Why did the battery explode? Lead-acid batteries can produce explosive mixtures of hydrogen and oxygen gases when they are being charged. When the employee wiggled the cable it probably sparked the explosive mixtures.
How do you prevent a car battery from exploding?
Always connect jumper cables to the dead battery first, then to the good battery. Another important safety precaution is to attach the negative jumper cable for the dead battery to an unpainted metal portion of the car frame, rather than to the negative battery post.
What happens to a battery if you overcharge it?
In a lithium-ion battery, overcharging can create unstable conditions inside the battery, increase pressure, and cause thermal runaway. Lithium-ion battery packs are required to have a protection circuit to prevent excessive pressure build-up and cut off the flow of ions when the temperature is too high.
Can a car battery explode in heat?
The intense heat can speed up the chemical reaction inside the battery, causing an increase in self-discharging and plate corrosion. “The battery can short out, the plates will actually warp in the heat and that’s when a battery does go bad,” said Tackett. In worse case scenarios, a bad car battery can explode.
When can a battery explode?
The battery can explode if sources of static electricity cause spark in the vicinity of batteries. Also naked flames or sparks of welding or any other sparks near batteries whilst batteries are on charge can cause a fire or explosion. As and when batteries are on charge hydrogen gases are evolved.
How do you treat a swollen battery?
Once you discover a swollen battery, you should immediately turn off your phone or laptop. Don’t charge it or turn it back on. Even if it’s still working, connecting it to power could be dangerous. The safest option is to take your device to a tech repair professional.
What happens if you touch an exploded battery?
Contact with battery acid can cause chemical burns. These types of burns might not show up right away. It can take several minutes or hours for symptoms to start to appear. Skin irritation, redness, and blackened or dead skin can be symptoms of chemical burns.
How do you clean up a car battery that explodes?
For alkaline batteries, dip a cotton swab in vinegar or lemon juice, and swab the spill to neutralize the basic leak. Use an old toothbrush dipped in the same material to scrub at a spill that has dried. Water can cause further corrosion, so wet a paper towel as lightly as possible and use that to wipe up the acid.
Can a double A battery explode?
Well, while it’s very rare indeed for AA batteries to explode in typical day-to-day use, ruptures or even small explosions aren’t impossible.
Will an alternator overcharge a battery?
Alternators mostly have fancy current and voltage regulators built in to prevent overcharging. Sometimes those fail in the full on setting and then yes your battery can overcharge, overheat, and boil over and fail.
Can an alternator drain a battery?
But when the engine is off, the alternator can’t recharge the battery, allowing little electrical mishaps to drain your battery entirely. The battery strain caused by these electrical whoopsies is known as a parasitic draw.
How long should I charge a dead car battery?
Recharging a battery with a typical charge amp of around 4-8 amperes will take about 10-24 hours to charge fully. However, if you just want to boost your battery enough to start the engine, it would take about 2-4 hours—or, if possible, you can use another vehicle to jumpstart your battery.
What temperature do car batteries explode?
But if a car battery is discharged because of damage to cells, poor connections or a charging system that isn’t doing its job, the battery could start freezing at the same temperature as water at 32 degrees Fahrenheit. “A 100 percent fully charged battery will not freeze until approximately minus 76 degrees Fahrenheit.
Will a battery explode in a fire?
Can batteries explode in fire? Yes. Fire is one of the main causes of explosions in most batteries. Heat does affect a battery’s chemistry and cause the internal metals to react.
