This cell delivered 3962mAh and 3985mAh in my capacity tests. Judging by Samsung’s “40T” designation for it I am sure its nominal/typical capacity rating will be 4000mAh. However, its guaranteed/minimum rating is always lower than the typical/nominal rating and will probably be 3800mAh or 3900mAh.

Great battery, quick charging and last for a few days
Very quick and good service . Thank you
Have been using this model/class of batteries for 8 months, which is why I bought more as backup.
At this point I can't fault them. 8 months old & still holding full capacity after recharging every 2 days.
I have absolutely no reservations about this product.
