2006 C230's Battery Explosion
Went to ACE Hardware to buy some tools. I start the car and as soon as I turned the key in the ignition, I and everybody hear a very loud explosion that sounds like a shotgun (stopped at the bank prior and I can imagine someone calling the police reporting a possible robbery if this had happened there, or while going 80MPH on the highway 
). I panic because it came from my car. I tried turning the key but it wouldn't turn; everything was dead. I opened the hood and saw smoke vapors from the back of the battery; the whole back cover was torn open. A kind veteran who happened to be at ACE offered to drop me off at my home. Gathered more money then my wife and I went to Auto Zone and bought a new battery. Upon replacing, everything was back to normal. I bought the car new in 2006 and for 11 years the battery was fine until this certain day.
My first and hopefully my last scary experience.

You had the battery for 11 years? :-O
You must not live in a snow area.
In New England, ~~5 years is typical for battery life.

How to Avoid Battery Explosions (Yes, They Really Happen)
August 26, 1999
If you ever hear an automotive battery explode, you will gain a new found respect for the raw power packed into these heavy lead-acid devices under your hood.
It's nearly as loud as a gunshot, as the plastic case blows apart--followed by the sound of toxic, highly concentrated sulfuric acid bubbling to the ground.
The risk of explosion is labeled on every automotive battery, though few motorists bother to read such warnings, let alone take them seriously. It's an unfortunate mistake, because batteries often do explode without warning.
Indeed, a study by the National Highway Traffic Safety Administration found that battery explosions in 1993 alone injured 2,280 people severely enough to have required hospital treatment.
Thirty-one percent of those injuries occurred during the use of battery chargers, 26% from handling battery cables, 19% from jump-starting dead batteries and 19% from checking or adding battery fluid. In all, the study found 7,051 injuries were related to automotive batteries.
And even if you aren't standing nearby and thus avoid injury, battery acid can severely damage the engine compartment, eating away wires and hoses as well as damaging paint.
Why do batteries explode and how can you protect yourself from injury when your hood is up?
It helps to know a little bit about 12-volt lead-acid batteries. They have six two-volt chambers, called cells, that contain a grid of lead plates submerged in sulfuric acid. Electricity is generated when the acid reacts with the lead plates and water.
One byproduct of the process is gaseous hydrogen, an element so highly flammable that it is used to power rocket engines. Charging a battery also generates hydrogen. And because heat drives up hydrogen output, you can expect more trouble generally in hot weather.
The danger is that hydrogen will explode if a spark occurs nearby. One source of sparks can be the battery itself.
As a battery ages, it loses water, leaving the top of the lead plates exposed to the air inside the battery case. Over time, this can lead to warpage of the plates.
When the driver starts the engine, the heavy demand for power can cause these already warped plates to flex, touch and thus spark, says Steve Mazor, head of engineering and safety for the Automobile Club of Southern California.
The most common cause of battery explosions upon start-up is dirty battery posts and cables, says Sam Memmolo, a master mechanic in Douglasville, Ga., and a nationally recognized automotive repair expert. The dirt prevents a good connection and allows electrical arcing. So it is a good idea to inspect and clean battery posts regularly.
Improper jump-starting is another leading cause of explosions. The mistake many motorists make is to connect the jumper cables to another car's good battery and then to the dead battery, a practice that causes sparking. 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. That allows any sparking to occur far from the battery itself.
The potential for battery explosions may be greater than it was 10 years ago. Some newer batteries are sealed, preventing motorists from adding water to keep the electrolyte (the mixture of sulfuric acid and water) above the lead plates. But many manufacturers have gone back to batteries with tops that can be removed.
Another problem is that new cars have much larger demands for electrical current, so batteries must produce more juice but with the same physical volume. One method used by battery makers to increase current is to space the lead plates closer together, but that only makes it easier for them to short, Mazor says.
In any case, motorists should always exercise caution when the hood is up, avoiding smoking or anything else that can ignite hydrogen.
