A typical alternator installation. This may generate too much hydrogen gas for the venting system to safely handle, leading to pressure build-up in the battery casing, and eventually ending up with an exploding battery.
Can a faulty alternator damage a battery?
Can a bad alternator kill a new battery? Yes, very easily. A failing alternator can overcharge, which will damage the battery. An undercharging alternator will leave the battery flat, which speeds up its failure.
What causes battery to burst?
In order for a battery to explode two elements must be present – explosive gasses, namely hydrogen and oxygen, plus a source of ignition, external or originating from within the battery. can gather in the plate separators leading to a possibility of short circuits between the battery plates.

Can a car battery explode if overcharged?
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 do you do when a battery explodes?

What are the signs of a failing alternator?
4 Symptoms of a Faulty Alternator
- Car Won’t Start. A dead battery almost always lies behind a car that won’t start.
- Engine Stalling. A dead alternator almost always leads to a car that won’t start.
- Electrical Issues. A dying alternator can lead to a wide range of other electrical issues.
- Unusual Sounds.
Why does my car keep dying with a new battery and alternator?
Why does my car keep dying with a new battery and alternator? Loose or corroded battery connections, continuous power consumption, charging problems, persistent need for more power than alternators and even inclement weather are some of the most common reasons for recurring automotive battery failures.
How do you test an alternator to unplug the battery?
If you’re tempted to test an alternator by disconnecting the negative battery cable, don’t do it. A good alternator may indeed keep the engine running without the negative cable, but this was never a good test. In the pre-computer days, you could pull it off without damaging anything.
Will a car start with a bad alternator?
When the alternator is failing, there might not be enough power in the spark plugs to keep the engine alive, which can cause it to stall for no reason while running, or to have trouble starting. Ignore this symptom, and your car eventually won’t start at all.
Will a bad alternator keep a car from starting?

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.
What happens if you touch a leaking 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.

What does it mean when a battery pops?
You did not describe this, but an exploding cell is typically caused by extremely high discharge current or by attempting to recharge a non-rechargeable battery. Either condition will cause battery heating, boiling of the electrolyte, high internal pressure and often a case rupture.
Can Triple A batteries explode?
Whether they are 9-volt, AA, AAA, C or D size batteries, all are capable of exploding. Few consumers are aware of that potential – despite fine print on the side of the batteries warning about the risk of explosion. When it happens, it can be downright dangerous.
What happens when the alternator goes out?
A bad alternator will result in a discharged (dead) battery and cause a vehicle to not start or run. Alternators are designed to maintain a battery’s charge, not to recharge a dead battery.
