Battery for T42.

[rustico]

I have a T42 2379DXU. I need an extra battery and I am wondering if anyone out there has an opinion concerning the pros/cons between the 9 cell Li ion battery and the ultraBay Slim Li Polymer battery. Thanks in advance for any input.

I think they're about the same price. 9 cell gives you more life though and is a bit heavier. You'll also have to hibernate to swap out (or plug in).

Personally, I have the 6 and 9 cell. Didn't want the ultra slim battery, not enough power.
