Same experience with some with a very short time use in a low draw device. Must have been funky cells. That experience is not common.

I’ve heard Amazon uses commingled inventory, which means they’ll happily mix counterfeits in with the real thing.
I KNOW they’ll readily throw reviews from different size batteries into the same file.
For the Ultimate Lithium the sealed packs + careful inspection of the cells is pretty good assurance of the real product.
