This one was not designed for ThinkPad 25. If you are looking for battery with maxium capacity, then you need 61++ (part number: 4X50M08812). This battery is 6 cell (72Wh), there's no 9 cell battery for this model (but when you add internal and external battery cells, then you'll have 9 cells in total ;) ).

Picked up my 61++ today. The system is estimating a battery life of 8 hours after being fully charged. I guess that's logical given that the 24+72 is double of the default 24+24 which gave me 4 hours. Is that in line with other peoples experience?

I decided to reply on this topic for future reference of others looking for the T25's bigger battery option.

 

It's actually not that trivial to get any information regarding this, it requires a bit of searching. I finally got to find some other topic (not mine) at the ThinkPad Forums. Might be interesting for others. https://forum.thinkpads.com/viewtopic.php?t=126342
