This is an update to my previous post about this :(. I received this replacement on the 15th but did not have time to test it until today. Originally when I had this issue, I sent a support eMail out and the original was replaced. However, 2 cycles in and I lost 12% of the original capacity, and the runtime dropped from the 2 hour range, down to 1 hour.
In addition to a 12% FCC loss within 2 cycles, it arrived with ~79% charge and then dropped to 6% without warning the first time I used it. Didn't think too much of it but that was kind of a warning call to double check if there are any issues. Same as before; it takes my OEM 47Wh fine.
