Not Green Cell, but I got a 6 cell replacement from GHU for my T440s workhorse. For the first week, it reported 9+ hours on a charge. Super cool, I thought, I can basically work outside as long as I like. The second week it went down to 2 hours on a full charge. 50USD down the tubes. I’ll pay the premium for OEM batteries from now on. This, of course, was just my experience, but reviews suggest it is a common one. I just thought it would be worth the risk.
