I've wondered that too. I did quick shock some button batteries for the garge door opener. It gave them another month's worth of life. I think you'd have to figure out on the battery which tab is positive, and which is negative, so that you don't zap it too badly. And I would do it for just a couple of seconds or so, to see if the charge takes.

Not a good idea, some battery chemistries can violently ignite. People have been badly burned. How much life are you getting out of the batteries? I have never worn one out but I don't keep phones for too long.

It is true, that the lithium batteries used in most cell phones have a propensity to explode. Zapping batteries is for older ni-cads that worked specifically because of the way their chemistry works.
Birken is right. Look at all of the laptop batteries that caught fire under normal use. Last thing I would want is my cell catching fire in my pocket or on the counter while I was sleeping.
I have had cell phones like most since they came out and have never had a battery go bad and tend to keep them for 2 - 3 years.
But recently had to replace the one in my sons Verizon Krazer after 7 months because it swelled up and would only stay charged for a few hours.
The kid in the Verizon was "nice enough" to pro-rate it down to $32.
I have had five phones in my life. Three of them now I would have kept but the batteries don't stay charged (two Motorolas one LG) after a couple of years and it ends up being cheaper getting a new phone than buying a new battery (although I haven't looked around online). Oh well, just wondering if there was an easy fix. Don't want any fires or explosions. Thanks for the help.

Batteries have a life span. Unless you have the equipment to take it apart, get rid of all the growth which shorts it internally and put it back together I thing your out of luck.
Check e-bay I am betting you can get some serious deals from there.

Shocking a single nickel-cadmium cell (NOT a multi-cell battery) is effective because Ni-Cd batteries form semi-conductive dendrites. (resistive filaments that "grow" from one plate to the other through the electrolyte separator and create an internal discharge path. Shocking cells destroys dendrites by burning them out, like fuse wires.
I don't know whether lithium cells form dendrites or not. If they don't, shocking them won't have much effect.
If you use a controlled amount of energy - say, by using a charged capacitor to provide the juice - the risk of ignition should be reasonably low.
But once lithium does ignite, it's a special hazard. Burning metals often react violently with water instead of extinguishing, dry-chemical extinguishers aren't effective, and CO2/Halon* extinguishers don't prevent re-ignition. You'll need a Class D extinguisher or a large quantity of dry, chemically-inert sand to smother and cool.
And to make life more interesting, lithium (along with sodium and potassium) is a Group I alkali metal which forms highly-corrosive lithium hydroxide when exposed to moisture.
*Yeah, yeah, I know they don't really contain Halon(tm) anymore. But everybody knows the name.

Yeah, sort of like that. Except that lithium ignites more easily and magnesium doesn't form a corrosive alkali.
On the other hand, there isn't a great amount of lithium in a phone battery. It'll be intense, but it'll also be short lived.

Quit using your car chargers and your batteries will last forever!!!! I have an LG 8300 that is 2 years old with over 2000 hours on the original battery and it has NEVER had a car charger plugged into it. I use a house charger with an inverter in the truck if i need charged throughout the day but most of the time i unplug it at 5:30 am and plug it in at 10:00 pm and the battery lasts all day. I don't plug it in on Friday as i don't get work calls on the weekend and i'll let it get really low, then plug it in saturday night.
