The description of the battery was very confusing. It is the right one for the ThinkPad T500. The warning that it is not for widescreen is apparently for another ThinkPad model.
It took a full week to arrive, not the expected 2-3 days, but that seems to be the Post Office's fault.
The battery fits fine in my computer, but after discharging it once to about 85%, it would only charge to 92%. After another cycle, it charged to 100%, but its reported capacity was 51Wh, instead of the design capacity of 56Wh. After a couple more cycles, it dropped quickly from about 40% to 0% and the computer lost power. Charging it from that state reset it to reporting 56Wh capacity and 100% charge, but I will have to cycle it a few more times to see if it really delivers that capacity.
I may be requesting a replacement for this battery soon.
