A friend gave me an old mini notebook/laptop thinger today. Aside from a dead battery, it works fine (I'm actually typing this post on it).
I could order a new battery, but I've always wondered about replacing cells myself.
I dug into the dead batt:
The issue of course is how to physically connect the replacement cells. The cell connectors in the original batt were spot welded on.
So the question is: Can I accomplish this without a special tool? All I gots is a couple of soldering irons.
