Another stupid question from Joe

[Joe]

How dangerous is it to charge nonrechargable batteries?

[Armin]

Why don't you find out for us?

[Eric]

... it's not dangerous; they just don't recharge very well, but of course, neither do rechargable batteries.

Well, my Calculus teacher recharges non-rechargeable batteries, and they seem to work just fine.

...but first make sure you cut it open & lick it so it gets the right amount of saliva in there to have a good charge

Because not even I am a big fan of battery acid stains on my wall.

Assuming it works as well as my rechargables, I'll be happy. =)

Thanks!

Battery explosion

A battery explosion is caused by the misuse or malfunction of a battery, such as attempting to recharge a primary battery, or short circuiting of a battery. With car batteries, explosions are most likely to occur when a short circuit generates very large currents. In addition, car batteries liberate hydrogen when they are overcharged (because of electrolysis of the water in the electrolyte). Normally the amount of overcharging is very small and so is the amount of explosive gas developed, and the gas dissipates quickly. However, when "jumping" a car battery, the high current can cause the rapid release of large volumes of hydrogen, which could be ignited by a spark nearby (for example, when removing the jumper cables).

When a non-rechargeable battery is recharged at a high rate, an explosive gas mixture of hydrogen and oxygen may be produced faster than it can escape from within the walls of the battery, leading to pressure build-up and a possible explosion. In extreme cases, the battery acid may spray violently from the casing of the battery and cause injury.

Additionally, disposing of a battery in fire may cause an explosion as steam builds up within the sealed case of the battery.

Overcharging, which is charging a battery beyond its electrical capacity, can also lead to a battery explosion, leakage, or irreversible damage to the battery. It may also cause damage to the charger or device in which the overcharged battery is later used.

Quiet RoMi! I think they were trying to get Joe to blow up his batteries!

[Nate]

You should connect two 9V batteries together...

I charged them for a few hours and they didn't blow up, so eh?

Done it before. Nice way to heat the house in winter!

What's the best method of cleaning up leaked battery acid?

[rabbit]

The tongue.

What's the best method of cleaning up leaked battery acid?

You can let it dry and then throw out whatever it was on.  Alternatively use baking soda or some other kind of basic (as in OH^- charged, not trivial) compound.  The compound shouldn't be strong and it shouldn't be diluted in water.

[deadly7]

Putting baking soda on it would neutralize some of it and get it closer to a reading that's neither an acid or a base on the pH scale, right?

[CrAz3D]

it should......but maybe we'll get luck & Joe will mix up baking soda and...hydrochloric acid & then we can get pictures of what a burned Joe's house/room looks like
