may be it is delibratedly? my laptop=20
destroyed a battery pack per half year!

Yesterday, I open one such expensive=20
staff: finding it has a mall pcb with one NMOS
and one OP(?). After further checking,=20
I am sure the pcb is only for over current=20
protection and causing difficult in V measuring!

Some how, I found those proken Li-ion battery
are still better choice for cordless screw driver!
Much long using time than their default one.

I using my new charger to charge those dead Li-ion.
I have just finished a very seccessful battery
charging/test project. It can successfully charging
Ni-MH, NiCd, Alkali, Li-ion battery.=20
