I have a 12 GB i7 t440s. All functions are normal, dirvers and bios updated.
The 24(Len 68 ) and also 48 ( Len 68+ )Wh batteries will both charge without trouble.
I also have a fewof the 72 Wh (68+) odd that the 48 and 72 have the same reference (68+?) battery as well.
PROBLEM: all 3 72Wh batteries will not charge on this device? they are fitting properly and proper spec for this laptop.
The 72 is not charging although recognized in the Lenovo Diagnostics software -battery diagnostic?

Are you sure these are real, OEM batteries or could they be aftermarket? A lot of the aftermarket batteries are junk, and there are a lot of fakes.

Have these been used normally for the last 4 - 5 years (based on manufacture date)? Stored in a closet?
