I'm getting the bottom line of this thread as bad news. Maybe Red will
Several months ago, I invested in a Lithium Ion battery for my
laptop/notebook computer. Two days ago, while on a Christmas trip, the
battery ran down just 35 minutes after I turned the computer on. Typical
usage in the past has been four+ hours.
I put it on charge overnight and after ten hours, the "power meter"
registered 46% and still charging. My recollection is that it used to charge
fully in less than three if the computer wasn't turned on, and maybe five if
it was working.
The 46% is not relevant, I understand that. Whatever its accuracy, it is
however precise and shows 46% reliably.
I think I can put a finger on the cause. I got distracted once and left
the computer running on the battery and went off for a weekend. The
automatic shutdown trips at 10% on the power meter, but I also know about
the self-discharge phenom.
So here's the question for Red, is there any way to
recover/revitalize/restore the battery? Or do I go pay $120 for a new one?
I haven't looked to see what alternative technology is available from the
