Hello 'm Very happy !!! Battery is detected despite Firmware 1.2 and works einwandfrei.Auch the problem with the self-discharge rate (2 - 3days unused, then battery flat) which many criticized here, I know nicht.der battery is with me now 1.5 weeks unused in the closet, have Camera just turned on, indicates full power. So price u.Leistung super.Da for weeks is mostly very bad weather, I have not made any major series of images and can not tell whether it has the same persistence as the original battery. But always worth at the price difference to Orginal- battery. If yes in 1.5 Sdt.wieder geladen.Also again absolute Entpfehlung from me.
