Works perfectly with Dell XPS 15 9560
Awesome, this work fine with my Dell XPS 15 9560 (2017). I've been using the laptop for at least 8 months since fitting this and there have been no problems at all.

Not too sure about the efficiency of this.
Not sure about this. It is doing the job but not sure if it holds its charge for very long henceonlytwo stars. Early days so it might just take a long time to reach full capacity. Time will tell.

OK pour mon pc portable DELL
Cette batterie rechargeable ML1220 est parfaitement adaptée à mon latitude 5290 2-en-1. Point négatif : aucun marquage sur cette batterie, donc on peut avoir un doute sur son côté rechargeable. Seul l'enveloppe mentionne la référence Point positif : la référence est bonne. Arrivée à 2,75V, le lendemain elle était rechargée à 3,05V (en laissant mon pc allumé et branché sur secteur)

It’s a CMOS battery
Does exactly what you need a CMOS battery to do. No more, no less. Longevity is still TBD, but so far, so good.
