recelling lithium packs
 

I wasn't going to short them.
I was considering discharging them further with a resistor.
However, it appears that further discharge runs the risk of damaging the
cells.
I'm going to skip the project for now, because I don't have a welder.

DO NOT short or discharge these batteries even when working with them.
Only when shorted or directly across a shorted load are they dangerous.
Discharging these batteries to a low level is not very good for them!
Only their normal amount of discharge during use is acceptable, and they
should be recharged soon after.

Even when these batteries are normally discharged, they can put out
enough current to cause burns, or flame. This is why proper practice is
required when working with these types of batteries.

I have good cells I can use to refurbish a lithium pack for my Fujitsu
portable.
I have cut open the pack, and can wire in identical replacements.

Since these cells are dangerous, I discharged them to 0% in my laptop.
They still read 9.7V (three 3.6V pairs of cells in series).

I understand that at this level of charge, they are still somewhat
dangerous.
But I've also read that discharging the cells to 0V permanently damages
them.

I would appreciate any specific information available on the correct
level
of discharge for cells which are being handled in the process of
installation.
