Interesting topic...I got my T61 in Sept 2007, it still has the nice
coloured IBM logo in the palm rest and display lid, so fingers crossed I'm
on the safe side. Could I identify shitty batteries by looking at them?
(brand, make, etc...)
So is it recommendable to use the computer without the battery on to span
the battery life? What I used to do is to run it without AC until
the battery dies, have read in several places that this improved the battery
life. I have a docking station so taking the battery out is easier for me is
suppose. If so, should I leave it charged or uncharged?
Cheers!

Just for the records: I can completely second this statement and<br>
experience :(<br>
<br>
The newer model's batteries are "evil" while the older (original IBM)<br>
perform way better. I have experience with X60, X61s (one failure, the<br>
others dramatically fast loosing capacity) and older models like X23,<br>
X24, X31 and T42p, all of them, even if years old, still perform<br>
reasonably well.<br>
<br>
Pity pity...<br>
If the bateries would be much cheaper I would not worry that much but<br>
with >$100 per battery this is a rather unsatisfactory experience.<br>
<br>
To save some cycles I now mostly run the devices without battery if<br>
possible - for some models a little bit "unstable" while typing but<br>
still better than ruining my batteries too quickly :(<br>
<br>
