Der Akku fängt nach 15 Monaten an, sich auf einer Seite aufzublähen und das Plastikgehäuse vom Laptop aufzudrücken!!! Wenn die Akkufolie undicht ist, kann sich Lithium mit Sauerstoff entzünden! Plötzlicher Spannungsabfall kommt hinzu. Warnung vor dem Kauf.

As parfaitement remplacé mon ancienne batterie qui au bout de 4 ans ne tenait plus du tout la charge. L'autonomie et parfaite pour un portable de cette gamme je trouve juste la charge une fois la batterie vide plus lente car PC branché est allumé il faut plusieurs heures..

Battery arrived sooner than the given delivery date although it did take a couple of weeks to arrive. It fits my Dell Alienware 15 R4 perfectly to replace the old swollen battery (top tip - don't drop your laptop down a flight of stairs!). Capacity also seems to be on a par if not slightly better than the original I haven't fully tested this yet but HWInfo shows 0% wear, the original showed 12% wear when new from Dell. Edit - the battery has swollen again after just over a year's use, I'm not sure if this indicates a fault with my laptop or the battery itself but I didn't drop it this time!

Battery is not detected by Alienware r3 15 laptop :( it was very hard to disassemble and replace the battery only to find out that the Battery does not work, or is at least not being recognized by the laptop :(

batería de calidad original buena duración
