Hello all... I have received a couple of used laptops, one the mobo is shot, the other one just has a battery that won't hold a charge. I am curious if both have 4cell/6cell batteries, is there a way to just take the cells out of the good one and put them in the other. The they are different mfr's, so the actual battery designs are different, but I would imagine the cells are much the same?? Anyway give me your thoughts, and I'll start combing the web for more answers and if I come across something I'll post it here.

Thanks,
Scott

Oh, no, no. no.

1. The cells could quite easily be different.
2. Laptop batteries actually have a lot of smarts built in.
3. The wrong cells could cause overheating or fire.
4. Not to mention the battery recalls because they could start a fire.

And those are ones that were assembled at the factory using the right cells.

At best you might just damage the charging circuitry on the motherboard. At worst smoke and flame.

I wouldn't do it. Nor would I buy a non Laptop makers battery off of the Internet just to save money.

hmmm... save some money, poor battery performance / Longevity, maybe burn down house. Nah, not worth it.

Good Luck.
