On the subject of batteries, I have a ThinkPad-701C with a single
NiCad battery. The battery is new (or so I'm led to believe). However,
I don't really ever use the battery, since I mostly just plug the unit
into the mains at home. I had been leaving the battery plugged into the
system anyway, but someone told me this is a bad idea. I was also told
that if I do use the battery, I should run it down to 0% then charge it
back up again, rather than just running it down to say 70%?
I want to preserve the battery for those rare occasions when I do need
to use it. What is the best strategy for doing this? I have taken the
battery out of the unit, but should I run it right down to 0% first,
or is it OK to leave it charged up while in storage?
