Laptop batteries

[Uncle George]

Well I've heard of many ppl using old laptop batteries in flashlights, but how about other way around?

Ie upgrading laptop batteries with the latest Li-ION batteries in the market today?

Has any one got any experience with it?

Having just replaced the batterie pack on my #1 laptop and having opened up the pack to salvage as many batteries as possible (6 out of 8) and observing the way the batteries are connected and the prices involved, I just don`t think that this would be a viable option - the purchase price of the individual cells is more than the cost of the pack, adding labor and connection parts costs and you have a no win situation IMHO.

In addition to what mr.snakeman said, in general, the cells used to make battery packs for laptops and such are top tier cells. On the other hand, most cells that are available as "loose cells" such as we use in our lights, are those cells that did not "make the grade" for use in pack making, or are "seconds". My advise would be to stick with OEM packs for a laptop, as snakeman said, your not likely to save any money anyway.

those things are way too hard to put back together anyways. They never seem to fit back together just right....

Ok, understand.
Thanks for the reply.

Cos I was looking at aftermarket battery packs.. and the general feedback I've gathered is... hit and miss.... some works for a very short time and some just wouldn't work.
So I thought building my own would ensure quality. It's interesting that 45/70 said Laptop battery are actually higher quality then the loose batteries we buy...

OEM SONY VAIO laptop battery packs are SOO expensive... sigh....

Most of the expense is because they use very high quality cells. 45/70 gave you good information.

They also have several thermocouples mounted to the cells and a temperature-sensitive breaker component, along with chips to monitor individual voltages of the cells and to keep track of data like cycle counts.

If you buy the good Panasonic cells then you'll be paying quite a bit, then trying to get everything together and working - quality costs.
You can get cheaper after-market batteries for your Sony laptop, but you won't get the same quality - quality costs.

It's hard to buy top quality for bottom dollar, that's just the way it is.
