Hello everybody.
I just changed my Laptop battery pack as the older battery pack would
recharge for around 5 minutes then stop. I could then use my computer
for a few minutes then it would switch off.
The curious thing is I after opening the laptop batteries they all
seem to be showing the right voltage. It seems that these NiMH are
showing memory effect. Does anybody know of a good way to discharge
them apart from a resistor. If a resistor what should its resistance
be.
The voltage reading inside the battery pack of each cell is around
1.27V.
Till later.

I don't believe NiMH batteries have memory effect. They are only good
for a certain number of charges. I suspect that is what has happened in
your case. The voltage will read good when charged but the amount of
energy stored is small.
And NiCds only exhibit a 'memory effect' in *very* rare circumstances,
mainly in satellite applications.

NiMh do exhibit "Memory effect".
