The battery "misses" as well in the camera as the original.
I use alternately the original and the replica and can not in the charging behavior, nor in the life (see update) notice differences.
The battery charge indicator works fine.
I hope that in terms of longevity of battery confirms the first impression!
From my first time 5 star and strong buy recommendation!
Update: The specified capacity of 1200mAh is probably not quite agree. Therefore, there is a star deduction for customer deception. Had the manufacturer specified in the price 900 or 1000mAh, 5 stars would have remained.
