Given the specs of your battery (10.8V 4.8Ah, i.e. 51Wh), an autonomy of one
hour means your laptop consumes around 50W, which is a hell of a lot for
a laptop, unless you keep it constantly in stress test (with full CPU and
disk, and graphics card load).
So I'd guess that your battery's original lifetime is a good bit longer (at
least 2h), and that when it lasted an hour, it was already on its death bed.

So even the design capacity has been changed, which looks rather odd.

I think it's been dead for a while now.

Get a new one, or try refilling this one.
