Bathroom scales just exploded !!

Dang the whole AAA split open down the length!

I thought it would be just be the cap on the end shooting out like it tends to do with electrolytic caps that have the vent fail.

it develops alot of strenght in that crimped area so it might not always be the weakest link, and with cheap batteries the body can also be severely corroded. In fact, the end cap seal might acutally protect the crimped area, so that might be the only place its not corroded

they plate the steel can so it does not rust I think. This is hard to do in the corrosive high pressure environment of a battery

That looks scary.
I can't choose between leaking or exploding cells...

[coppercone2]

its stored energy!

It is the first time I hear about an exploding cell, but I also have seen a few cases that were evident the gas leaked at high velocity, hinting of high pressure inside. One of the saddest for me was a Duracell that took my beloved HP95LX - the white corrosive substance was clearly visible - it corroded all the multi conductor flat cables and several parts of the PCB

Most EE's have at some point tried to solder wires onto a coin cell and had it pop open from the heat.

Yeah I did that in typical absent minded fashion, to replace the coin cell in my USB microscope, and yeah it did pop.

The Ruwido batteries are labelled as product of Austria. I'm guessing they are in the EU and the EU has rules for everything. A quick search of google for their batteries exploding just gets a few mentions of Duracell's blowing up.

I have a few broken cell phones I collected over the years, I should toss any batteries, and not keep them packed away in boxes.
