I do have a working battery that will hold an hour but finding those will get harder and harder. Also, imagine a 7200mah 6 cell that has the same capacity as a 9 cell. 2400mah isnt the standard anymore and 8 hrs on a recelled 9 cell is possible now. Once all the remaining working ones die, then what.wujstefan wrote:Isn't it just better to get a nice working genuine battery? They have surprisingly long livespan. I personally own at least 5 good working batteries for T4x/R5x units.

Summary of above (previous) posting:
We have a T410 laptop, and from our experience we will stick with official Lenovo batteries going forward.
We once tried a 9-cell non-Lenovo battery (ie: not made by Lenovo), and it died quite quickly.
To add insult to injury, our original (older) 6-cell Lenovo battery was still working, long after our newer non-Lenovo (not made by Lenovo) 9-cell battery had long since died !
(The older 6-cell Lenovo battery was abused due to non-use; we left it permanently in a completely discharged state for months at a time).
Again, from our experience we will stick with official Lenovo batteries going forward.
[In case you are interested, our T410 is currently working on a newly bought Lenovo branded 6-cell battery].
(Disclaimer: we are fellow Thinkpad users; we do not work for Lenovo).
Current Thinkpads: X1C4 | X1C3 | X250 | X230 | T410
Retired Thinkpads: T42 | 560 (circa 1996)
