I got news for you buddy,
your original laptop battery was made in china too!
so stop slamming them, all your equipment is made there.
Oh yes, a look at the "Made in ..." notices can be quite enlightening.
as for how long they last, anyone who tells you 8
hours is full of it.
maybe 2-3 hours on a good day.
Depends very much on laptop and battery. The Thinkpad X200 with the extended
battery here is easily good for 6 hours playing video.
unless you're watching videos, or playing games,
etc... even then maybe 2 hours.
but if the power specs don't line up, yeah, bad idea, no matter where you bought it.
there are tricks on the net to deep discharge batteries, and sometimes that brings them
back,
wipes the ni-cad memory.
You have to go back quite a few years in time to find NiCd chemistry in laptop
batteries. Anything designed in the last several years is some kind of
Lithium based (LiIon, LiPoly, ...) battery chemistry. And that doesn't like
deep discharge at all - deep discharging Li-based batteries is one of the
more reliable ways to kill them.
