If anyone has a swelling battery in their macbook just pop it in the fridge for 8 hours on an empty charge and the swelling magically disappears!

Anyone else have success with this?

This sounds rather dangerous...for any laptop, more-so on a laptop that has a glass screen...

Bulging/swelling lithium-ion batteries are dangerous and, as far as I know, Apple will replace them free of charge.

The posts I've been reading have stated that apple won't replace bulging batteries that are out of warranty.
If under 3 years of buying your computer, you shouldn't have an issue. After 3 years, the Apple store may balk, but you never know. Could run into a nice employee that hooks you up?!?

This isn't a solution. You're curing the symptom, not the disease. What you suggest is dangerous, potentially very so. Li-polymer and Li-ion batteries are complex chemical cells. If the voltage is allowed to go too-low, the cells break down and give off hydrogen gas. This is the swelling in the battery. Putting it in the freezer, you're just reducing the volume (and allowing for some adsorption) of the hydrogen. It's still there. If you were to use this battery, the hydrogen can potentially ignite, starting a fire.

Once a battery swells, it needs to be properly disposed. Treat it as an ignition source, and don't let it near flammable items.

Not to mention putting the battery in the freezer could cause some moisture buildup that you may miss when you wipe it down after. If anyone tries this, be sure to just leave the battery out for a couple hours to use it to let everything evaporate.

I have a lithium ion battery that has swollen due to overcharging. Can it be fixed? Can I use this swollen battery to supply 12V to my circuit .What should I do if I don't have a spare? Can I simply fix this battery?

The battery needs to be replaced and properly disposed of. A swollen battery can explode and/or start a fire.

This is extremely dangerous and negligent advice. If your battery is swelling it is telling you it has failed and is on its way to a catastrophic failure.

That battery could start a fire. It should be disposed of properly, and soon.

Why would anyone want to put something that is dangerous and could release chemical in a frig? It's really a stupid idea. You may end up needing to replace the frig unless you don't mind eating foods with those chemical...replace the frig ill cost more than the battery!
