			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).
