Review by Sarah

The dimensions were the right one for the first delivery, only the locking button of the battery could no longer be closed. But it wouldn't have been a problem for me either. Everything was fine the first time it was charged. The first use was over after 20 minutes. From this point on, the battery was no longer recognized by my laptop and was therefore unusable. After contacting Subtel, I got a replacement (the alternative would have been money back). The new battery fits perfectly (lock closes again), is recognized and has lasted for a week now. So I can't say anything about the service life. So far it lasts around 1.5 to 2 hours when watching a film, a little longer when working on the Internet or with Excel or Word. Overall, the back of the battery is a bit thicker than the conventional one (4400mAh), so that the battery is a bit inclined on a table top. Personally, I find it very pleasant when writing and the ventilation is better when I hold the laptop on my lap. Conclusion: The battery fits, has enough power for me so far, contact with Subtel was nice, only a bit tedious (2.5 weeks from contact to delivery of the replacement battery), only I was never convinced by GLS and probably won't be more.

Die Abmessungen haben bei der ersten Lieferung gepasst, nur die Verreigelungstaste des Akkus konnte ich nicht mehr schließen. Wäre für mich aber auch kein Problem gewesen.

Beim ersten Aufladen war noch alles gut. Die erste Nutzung war aber nach 20min beendet. Ab diesem Zeitpunkt wurde der Akku nicht mehr von meinem Laptop erkannt und war daher nicht nutzbar. Nach Kontaktaufnahme mit Subtel bekam ich einen Ersatz (Alternative wäre Geld zurück gewesen). Der neue Akku passt perfekt (Verriegelung geht wieder zu), wird erkannt und hält jetzt seit einer Woche.
Über die Lebensdauer kann ich daher nichts sagen. Bisher hält er beim Filmeschauen ca. 1,5h bis 2h, beim Arbeiten im Internet oder mit Excel oder Word etwas länger.
Insgesamt ist der Akku hinten etwas dicker wie der herkömmliche (4400mAh), sodass der Akku auf einer Tischplatte etwas schräg steht. Ich persönlich finde das ganz angenehm beim Schreiben und auch die Lüftung ist besser, wenn ich den Laptop auf dem Schoß halte.
Fazit: Akku passt, hat für mich bis jetzt genug Leistung, Kontakt mit Subtel war nett nur etwas langwierig (2,5 Wochen von der Kontaktaufnahme bis zur Lieferung des Ersatzakkus), nur von GLS war ich noch nie überzeugt und werde es wohl auch nicht mehr.

Review by Philipp

Definitely suitable for the Aspire 7745. Super capacity and the laptop has become more ergonomic because it is now higher at the back. Buy recommendation! Without WiFi and 3D applications, it now shows me 7-8 hours of running time.

Für das Aspire 7745 auf jeden Fall passend. Super Kapazität und der Laptop ist direkt ergonomischer geworden, weil er hinten jetzt höher steht. Kaufempfehlung! Ohne W-Lan und 3D Anwendungen zeigt er mir nun 7-8 Stunden Laufzeit an.
