Thinkpad Z60T/Z60M Ultrabay Battery compatibility

[check1t]

Ultrabay battery (FRU 40Y6789) features 2.7Ah capacity, compared to standard 1.5Ah capacity.
It is officially compatible with ThinkPad R60/T60/T60p/Z60t/Z60m/Z61t/Z61m models

Some ebay sellers call it Advanced Ultrabay Battery

The height must be 9.5mm for the Ultrabay slim model, but I could not verify it through the battery specifications.

Does anyone tried to install it in T4X?

I dont know if it will fit - but since its built for a different family of T series laptops it might not work. Im using the info that accessories for T2x will not fit on the T4x. However maybe someone has done it??
