Isn't this dangerous?
I am genuinely curious since I've always considered batteries to be something to be handled with care. I mean, it's not like you are carrying around a pack of TNT, but I would've never thought of opening it to replace the cells.
For example, do the batteries have internal circuitry that could cause problems if you put in the wrong kind of cell?
- dsr_ 11y agoIt's not particularly dangerous. If you can jumpstart a car, you can do this. The key is to remember that laptop batteries are rarely produced by people with actual battery expertise. Instead, they string together a certain number of (usually) AA-sized battery cells to produce the appropriate voltage and put that in a custom case. Crack open the case, read the numbers, order replacement cells, swap, check with a voltmeter, close it up and try it out.

- keenerd 11y agoThe 701 uses NiMH cells so it is very easy to work with compared to a li-ion pack. Here's an example: http://www.conradshome.com/thinkpad/701/battery/ http://www.conradshome.com/thinkpad/701/battery/
- saganus 11y agoAha! very interesting. I had seen pictures of opened battery packs before, and I definitely thought they looked like regular AA batteries. But I also never thought that it wasn't only the looks. It would be nice to have this same analysis done for different models. Like having a database for battery pack models where you could find the ordering of the batts, the chips that they have etc. Also, what would've happened if the corrosion actually had killed the chip? then what? can you find parts to replace those?
