My T61 is 2.5 years old, and by that time I bought a noname 6 cells
battery =E2=80=9Cfor every day use=E2=80=9D, saving my lenovo 6 and 9 cells=
 for when I
really need them (I keep them mid-charged, and use them from time to
time). The noname one is always kept in my ThinkPad, using smapi
controls to keep it between 30% and 70%.

At that time, it's still pretty fine:

corsac@hidalgo: acpitool -B
  Battery #1     : present
    Remaining capacity : 21550 mWh, 43.28%
    Design capacity    : 56160 mWh
    Last full capacity : 49790 mWh, 88.66% of design capacity
    Capacity loss      : 11.34%
    Present rate       : 0 mW
    Charging state     : Unknown
    Battery type       : Li-ion=20
    Model number       : COMPATIBLE
    Serial number      : 38


Looking at the battery itself, the brand seems to be a =E2=80=9CDLH=E2=80=
=9D, not sure
if it helps you.

Cheers,
