Review: Identique à l'original. A voir dans le temps.
Review: Dieser Akku passt tatsächlich in meinen Laptop; meine erste Bestellung (anderer Lieferant) passte trotz entsprechender Beschreibung leider nicht. Diesmal ist alles ok und der Akku scheint auch zu funktionieren. Mehr ergibt sich dann erst nach längerer Benutzung. Vielleicht ergänze ich die Bewertung dann noch.
