Help fixing Sudden Battery Power Drop on Toshiba Satelite

Hi there,

I have a Toshiba Satelite 1005 and am having problems with the
battery. When I'm off AC power, the battery meter goes from 100 to 95
to 90 and then suddenly drops to 0% in about 15 minutes and then the
computer is dead until I recharge on AC. What is the cause of the
sudden power drop? Do I need a new battery or is there some type of
battery refresh I need to do? Thanks.

That's the way mine tanks. My battery is good for about one year -- and I
ain't exactly crazy 'bout buying another one of the expensive things which I
am about to do again. Reminds me of pricey printer cartridges that come
with inexpensive printers.

You may need to save your old battery cover as the replacement ones don't
always snap in correctly or match the color of the laptop. Least mine snaps
off readily so I can switch cover plates. You'd think for a $180 battery
the thing would fit properly. Oh, Toshiba told me they no longer carry my
two-year old laptop battery and I need an off-brand one.
