I have a Motorala c343 cellphone with a ssn3825a 3.6v battery which I
dropped into a puddle of water and shorted. Is there any way to try to
recover this battery? Some one said that he read an article in a pc
magazine which suggested putting it in the freezer which might break
the short? This did not work. How about putting it in a vat of
nitrogen or C02?
Some else suggested hooking it to a high voltage source. How high,
220V? Any ideas where I can get a higher source? Fly a kite and
access 1B V like Ben Franklin? That might just vaporize my battery,
but might be fun. Although we don't get too many thunderstorms here.
Before I purchase a new battery or phone, I want to try to hook up
another Nokia BLS-2N 3.6v battery from an old phone to see if my phone
still works. It does not have an amperage rating, but since I see the
standard AA cells sold as an emergency battery this might just work.
Does anyone know how the insides of these batteries are wired? E.g.
have taken one apart?
Both are labeled - on the LHS, and + on the RHS
They both have 4 leads, but with different form factors of the
batteries? Should I just hook them up the most obvious way? Should I
test the leads with a light bulb first?
Does anyone know of sites on the best way to design a do it yourself
housing for the Nokia?
Disclaimer, I have a lot of knowledge but not in practical stuff. I
think I have a track record of destorying more than fixing things, but
hey, that is the price of learning?

"Motorola" batteries being a good brand should have some protective
circuitry inside the battery itself, as well as the charge control built
into the phone. The normal protection is a fuse, probably arranged as a
very narrow track on a micro pcb. Also there might be a zener diode to
protect against over voltage. Before you try and open the battery you
should remember that it is a LITHIUM cell, and can self-destruct
violently if you get it wrong. It's around 30 dollars for a new battery,
how much for new fingers?? Have a look at
http://www.powerstream.com/li.htm and remember the laptop problem!
Regarding trying another battery to test the phone, make sure the phone
is really dry inside and try connecting in the 'obvious' pattern. If you
can test the battery you can check for + and - on the contacts. Look and
see if the phone is marked with matching symbols.

There is a water sensor that changes color if the phone gets wet.
Most companies do not honor wet phones.

Ahhh....be informed a Li-Ion battery shorted goes off like a roadside bomb,
which is what the Dell/Sony-battery recall was all about. There's a
webpage showing a Dell laptop exploding on a table at a computer conference
in front of astonished conferees, but I don't have the URL at the moment.
It's very impressive to see a Li-Ion battery explode......

One of the fun things to do to that little geek snot at the service
counter, when he jerks your cellphone out of your hand with that snotty
cellphone attitude, is to say, "Ah, that's the phone that fell out of my
pants into the loaded toilet!"
Look on his/her face?.........................PRICELESS

"Roadside bomb"? Explode? You are delusional. Roadside flare,

I had a Panasonic*A100 that went through the washing machine and survived.
(I left it on the window-sill 2 days in the sun, recharged the battery and it
worked.)

Not at all. Perhaps the "road-side-bomb" analogy is a bit extreme,
however... personal injury is a distinct possibility. Don't take our word
for it. Go to Google and find out for yourself.

There was a news story here in Florida a few weeks ago. The battery
in a man's laptop started smoking, so he tossed it into the back seat of
his king cab pickup to get it away from his young daughter. It set the
truck on fire, and it was a total loss.

put it in sun for a day or so and then keep it under ur pillow for
about 3 days..
sun will convert the water within into vapor (the vapor will still be
traped inside) while the pillow will then absorp it and also heats it
up slowly...(use a pillow which has hygroscopic material inside it,like
cotton)
dont try to heat it the battery will die...

Re: li-ion battery
After a four days, the phone dried out, and when I connect it to the
charger, the phone comes on. Unfortunately, the battery cannot be
charged. Do you think it is shorted for good, or just still wet
inside?
What I mean by the obvious way is that there are 4 contacts on the
Motorola c343 phone and 4 contacts on the Nokia battery (for another
old cell phone non e911 compatible).
BTW, the Nokia battery is good, as I tested it in the old phone.
I connected each contact on the phone to the corresponding one on the
battery, making sure that the + side matched the + side on the other
one. The phone did not come on.
Either the contacts are not firm, or the wiring has changed. Does
anyone know if the wiring ordering is still the same in the Nokia
BLS-2N as the Motorola ssn3825a??
Can anyone think of another reason why this might not work?

Re: li-ion battery
The guy who suggested connecting it to a high voltage source was my lab
techie.
I did see the video of the exploding laptop, but think it is a fake.
There is just way too much flame for a battery like that, and the crowd
in the background just stands around watching it. With flames like
that, I'd be running for the fire hydrant.
I use to make home made gun powder and bottle rockets as a kid, so its
hard to fool me.

No, don't do it! Once the Li-Ion battery drops to a low level, Li-Ion
battery chargers are made to not charge the battery. Because if they
did, they can explode. It just isn't worth the risk.
