Laptop Battery Lifetime Revisited

[Sunset]

.....

I might take my tool batteries in to have the cells replaced, I've heard that is cheaper? Supposedly, some local places will do it, you need a spot welder to get those cells together. Hmmm, maybe buy a cheap spot welder from Harbor Freight? But the tool is > 10 years old, I have two batteries, so I just swap them. Probably time for a new tool anyhow.

Don't you think they just solder the batteries together and not spot weld. On very small devices I've taken apart, it looked like solder, but I've not yet taken a tool battery apart.
