2.5 hours of battery life isn't going to cut it when I go back to school in the fall.
I found the ultrabay battery on lenovo.com, but it only lists support for the T60p, not T61p. I assume they're similar enough that it should work, but I figured I'd check here.

Yes it will work on the T61p. The ultra bay battery isn't that great. Since it always discharges first, it wears out quickly. I had it for my R60. It was at less than 50% capacity after four months. I think the nine cell though it does add a bit off weight might be a better choice. I have it for my R60. I get about 5.5 hours on it with medium settings though with a bigger screen and dedicated card you probably won't get as much unless you are will to dim the screen more.

There is a post at the forum which presents a very palpable reason the Ultrabay battery wears so quickly (other than frequent recharging).
There are three cells there and hence they are discharged with a high current (per cell) to deliver sufficient amount of power.
Thus - the more cells - the less current per cell - the longer life of the battery.
Furthermore, the more powerful laptop - the higher current - the shorter battery life.
In a nutshell - the Ultrabay battery would serve longer in X series then in R series, then in T series and will end up its life very quickly in Txxp series.
PS
To support the above: I have an 8-cell TravelBattery for my HP mobile workstation. It has been charging any other day for three years now and still offers 2-3h (depending on the workload). -
Yes it will work I have the ultrabay battery and get 4.5 hours
-
I've got the 9-cell battery in my T61p as it is, and I only get 2.5 Hours, I'm looking to help improve that. I'm thinking of either the Ultrabay battery or an external notebook battery.
-
2.5h @ 9-cell - looks depressive
What about another 9-cell battery and external charger? -
it's also another things to haul around, where the ultrabay could just stay in all the time -
Very true, however, do not expect more than hour from Ultrabay.
Anyway - if a specs of the new W500 disappoints I will consider such a battery for mine T as well. -
EDIT: And the ATI graphics in the new Thinkpad lines make them a no-go for me. Until ATI makes some leaps and bounds in Linux support, I won't be using their cards.
Ultrabay battery for the T61p?
