Just found a 12V NiCd accu pack. I guess I haven't charged it for about
3 or 4 years. Do you think I can still put it in the charger and use it, or is
it lost ??
But now for the real question : I have a Toshiba T1000 portable, which wants
a 9V DC input from the charger. Can I just hook up an external 9V accupack
to the 'adaptor' input, or a >9V pack (like the one mentioned above) with a
simple 7809 or LM317 based voltage regulator circuit, or would that damage the
portable ?? It doesn't have interchangable batteries, so I don't have the
option of buying 'official' extra accu packs.
If I can't use the accupack 'just like that' on the charger input, what kind
of circuit would it take to achieve that ??
Cya,
