T61 WXGA 4 cell vs. T61 XGA 6 cell battery

[vk60402]

Is there a difference between these two batteries? For some reason, non-widescreen notebooks come with 6 cell but WXGA come with 4 cell.

I realize that the form is slighttly different (WXGA vs. XGA) but is there a difference between these two batteries?

They both sit flush when installed on their respective Thinkpad. The 6-cell holds (would you believe) about 50% more charge than the 4-cell.

Because of the design of the widescreen, only the 4-cell sits flush. The 6 and 7-cell stick out.

Wit the non-widescreen, the 6-cell sits flush and the 9-cell sticks out.
