New iFixit battery capacity dropping after 5 cycles

본문:

I purchased a "new" macbook battery to replace the old swollen battery in my 2009 MacBook Pro 13in. The battery I received was rated for 5656mAh. I replaced the battery and used Coconut battery to diagnose the new one, and it said 5519mAh was the full charge capacity after 2 cycles. I figured it takes some time to get adjusted, however, after 5 cycles it has dropped to 4855mAh maximum capacity out of the 5770mAh manufactured capacity. I am worried that I received a defective battery.

Is this the case? Or do i need to deplete the battery and cycle it a certain number of times in order to bring the capacity back up?

Any help would be much appreciated
