5 out of 5 eggsNice improvement

Pros: Three times the capacity of the original battery that came in my R61i (7800mAh vs 2600mAh). Genuine Lenovo 9-cell.

Cons: Expensive. Sticks out a bit.

Other Thoughts: Worth the money, despite my comment of it being expensive. The fact that it sticks out can help protect the power connector on the back of the machine.

I will echo the previous comment that the picture is incorrect as of the date of this review.. This is a 9-cell battery as described, what's pictured is slightly smaller.

1 out of 5 eggsNot for T60 Wide

Pros: Genuine Lenovo Battery, great availability. Will do business with Newegg again.

Cons: Battery listed does not fit the T60 wide laptop, had to return, Newegg was great on the RMA process. The correct 9cell for the T60 wide is 40Y6797 gathered from the Lenovo site.

Other Thoughts: Went to the lenovo site to pull the FRU number. Then crossed to the Newegg site. Must be PAINFULL to keep up with all the variuous models ;-)

5 out of 5 eggs9-cell

Pros: the picture shows a 6-cell, but it's definitely the 9-cell..

im using it with my t-400 and i get about 6 good hours.

i accidentally let it fully lose charge but it's currently recharging fine.

it's not loose like my 6-cell.

Cons: it sticks out.

Other Thoughts: i used to get like 2 hours with my 6-cell; turns out i had a bad OS.
make sure ur computer doesn't idle at anything more than 12W
