Restore your notebook battery quickly and cheaply.

A quick one for you notebook owners, or those of you offered an old notebook with a dead battery. As I'm sure you know, notebook batteries can be expensive. Upwards of $100. But you can easily restore it for a fraction of that price.
In this short video, a tech-savvy guy shows you how to remove the dead cells, replace them and do a little light soldering. And there you have it. One brand new battery with more power than it ever had before, and for a lot less cash. Now that's what Wisebread is all about.

While the theory seems sound, I'm a tiny bit hesitant to try this on a new (newish) laptop. But I do have a 10-year-old Dell laptop that is still running ok that I can try this on. Yes folks, I never throw anything away. That's why I run a frugal living website!
have you tried this yet?
i don't have any soldering experience except for that one time in shop. the potential for exploding made me wary of trying this.
..as my notebook is brand new. But I'm tempted to buy an old one on Ebay just to see how easy it really is.
This looks dangerous. I think I would be too afraid. With my luck the batteries would explode for sure.
Hey-why not rejuve a battery pack with a conductive epoxy instead of soldering? I think JB weld would do the trick, and they make a quick set version. JB weld is used for repairing engine blocks, so you should keep the rest of the tube for any engine repair. Many years agone, back in the winter of the great snow, a friend helped me patch an old exhaust manifold that couldn't be welded due to heating driving out the carbon or some such. Worked fine, lasted a long time.
Check my claims-the manufacturer should be able to confirm if it's suitable for this application.
And the content of this video has been removed-wassupwidat?
Even if JB Weld is conductive, and I'm not sure that it is, it will never be a substitute for solder in an application such as this. A good solder joint is essentially a zero resistance joint. Resistance at the joint will produce heat which is not what you want, especially with a Lithium Ion battery. Skip the JB Weld and do it properly, don't cheap jack it.
Great tip but please say "solder" properly, "sodder" ???
Would this work for a Mac battery as well?
Hello - please DONOT !!
it is dangerous because LIthium Ion batteries used for Laptops can easily EXPLODE, if they are overheated vhen soldering. At use if the contact is bad, heat can happen also, and it will be dangerous. If you are not wounded, you should also know that Lithium itself when inhalated is lethal at very little quantities.
My suggestion : find a hack to use cheap standard Nickel Cadmium batteries instead, but it would be necessary to have a little electronic knowledge to simulate a Lithium package. If anyone has already done that please let us know !
