Not at all strange. IBM thinkpads are famous for basically killing
batteries. Certain models in particular, but I get the impression that IBM
really could not care less about how many cycles you get from your
battery.

Google for "thinkpad battery" if you want to read about 1 year (or less)
battery life.

I have a 9 year-old Toshiba Portege that still gets 3 to 4 hours on the
original L-ion battery. My technique has been to treat it like a lead-acid
battery, avoiding deep discharges.

Cheerful regards,

Bob
