The Bulk Battery is 4-5 grams lighter than the original Samsung battery and reaches only 2/3 of the holding period.
This was the "new" battery (with the S / N AA1F312RS / 5-B) worse than the one that should be replaced.
After removing the packaging film around the battery is on the silver coating: JKN484655 / AB 00Tr A1MK18ML 04B2
After buying a original Samsung battery in the Samsung Store at a significantly higher price, the desired goal is achieved with me: holding time 2 days!
