> remove the cells I was under the impression that laptop batteries usually have on-board memory for holding charging parameters and such, and if you remove the cells, the memory contents gets lost and you cannot charge the battery anymore? EDIT: More questions: Do you need a spot-welder for this? And how do you get the battery pack open, since they are usually glued shut? |

Some do, most don't. I've yet to see one that was that tricky, though I would suppose there must be manufacturers paranoid enough to put that in.
> Do you need a spot-welder for this?
If you want you can buy cells with strips already spot welded on so not necessarily. But it certainly doesn't hurt, they're not expensive though. K-weld is one of the better ones.

That can be a bit tricky depending on the manufacturer they may have the whole rim glued shut or maybe only a few strategic spots. I've yet to find one that I could not open, but some do take a bit of patience. And once you know how a particular model works the next one usually goes ten times quicker.
I realize that what is easy for me may be hard for others, but this being hacker news and the fact that there is a substantial intersection with the maker scene here I don't think such a subject is out of place.
