Bosch 36v
They are unsafe due to not having the electronic they had, if they get
discharged to much they tend to get very hot very quickly when you try
to recharge them, but, and this is a big BUT, if they are above 2.5 V
there are no problems with them EVER. I have a moded 2D M@G with a 35W
OSRAM halogen and they work like a charm running at 2.2A when fully
charged and they are rated at 1800 mAh. Anyway most of them are SONY,
few are PANASONIC and 9 are GP. As a personal note, the PANASONIC ones
look and work best even after some really heavy use, SONY's tend to get
really messed up after some 300-400 charges, and all older IBM laptops
use PANASONIC, also some really old COMPAQ's use old SONY cells that
work perfectly after 8 years of use although they are rated at 1300 mAh
but they have some really complicated electronic to control themBare cells from good brands of laptop will usually be good brands of
cells, but they are going to be unprotected, and are not "safe
chemistry" cells like the LiMn found in power tools. I would not
consider them to be the least safe li-ion cells, but not far from it. I
do not believe they are what you are looking for.
