Yesterday my wife's Toyota Corolla had a battery moment.
When she started the car, after it had been parked it for about two
hours,
there was a loud explosion.
The results of the battery's side splitting event can be viewed at
ftp://ftp.meraka.csir.co.za/pub/in/Battery_Explode/
The battery centre suggested it was possibly over charged. After I
installed
the
new battery I measured a charging voltage of between 14.2 and 14.3 volts
-
depending on the engine refs.
According to my knowledge a charging voltage of 14.2 to 14.3 volts is
quite
OK
for a charged car battery.
Any suggestions why the battery exploded.
The battery showed no signs of failing before the event, so I doubt
that the battery level was low as someone suggested. I also topped up
the
battery with distilled water about 3 months ago.

You didn't see that? It exploded when she started the car. Sort of lends
credence to Jim's comment about a shorted starter.

Seems to clean up "post crud" rather nicely... lots of experience. In
fact, when replacing batteries, I soak the cable connectors in the
"brew" first. I've used Sprite or 7-Up in a pinch, but those leave a
sugar residue.

Was it a made in China battery or a good one?

The "two hours" means there wasn't any hydrogen under the hood, and
the explosion on starting means either
1) the battery case was sealed _and_ there was a starting-driven
ignition source inside the casing, or
2) intense, rapid heating, producing steam.
Did I miss anything?

Click and Clack on Car Talk insist Coke works great. Phosphoric acid,
apparently, is what does it. Great for sucking calcium out of your

It doesn't look over charged, at least as a cronic condition (no
bulging sides), the failure (expolsion) was internal judging from the
fact that the end panels blew out.
How high was teh ambient temperature?
One can charge a battery at a rate that will NEVER overcharge it.

But hydrogen will STILL be generated - until there is no electrolyte

The explosion was due to hydrogen around the battery, plus an
igniting spark.
The presence of hydrogen indicated that the battery had been
(recently) charged.
Some kind of loose connection created that igniting spark on startup.
The car may have been parked for 2 hours, but that hydrogen is
non-mute testimony of the battery had been charged.
How can free hydrogen "around" the battery blow the end panel out? The
over-pressure arose on the inside on the battery. I would second the
opinion that the electrolyte level was low.
By the way, did anyone bother to neutralize the spilled acid inside
the engine compartment? All surfaces were possibly contaminated. Rinse
them with water, then a baking soda/water solution and then more water
to prevent widespread corrosion. Don't trust the service guys to do it
- they don't have any baking soda.

amazing that a car sitting outside for 2 hrs could build up enough hydrogen
under the hood to explode the battery. I'd think that the usual wind
currents would dissipate any hydrogen.
Yea...i thought of that.

So...that seems to leave out low-level charging over that 2 hour
period, implying a higher charge rate and over a shorter period of tie
and "recent" in the chain of events..maybe during the last half hour?

Plugged vents?
One of those wonderful "sealed" batteries?
Any of them. Even the old screw tops could plug up. The hole was
small to keep things out, and they were easy to plug.
It wasn't that long ago that I was told on this group that 'Car
batteries don't explode'.
Of course not...they just "expand rapidly"...

Yesterday my wife's Toyota Corolla had a battery moment.
When she started the car, after it had been parked it for about two hours,
there was a loud explosion.
The results of the battery's side splitting event can be viewed at

The battery centre suggested it was possibly over charged. After I installed
the
new battery I measured a charging voltage of between 14.2 and 14.3 volts -
depending on the engine refs.
According to my knowledge a charging voltage of 14.2 to 14.3 volts is quite
OK
for a charged car battery.
Any suggestions why the battery exploded.
The battery showed no signs of failing before the event, so I doubt
that the battery level was low as someone suggested. I also topped up the
battery with distilled water about 3 months ago.
Plugged vents?
One of those wonderful "sealed" batteries?
Any of them. Even the old screw tops could plug up. The hole was
small to keep things out, and they were easy to plug.
It wasn't that long ago that I was told on this group that 'Car
batteries don't explode'.
Of course not...they just "expand rapidly"...
