Review on Dell Laptop Battery E6420, E5430, E6520 & More - Long-Lasting Power For Inspiron & Vostro Models by Cameron Rosa

It's okay. I mean, it's compatible and recognized by my Latitude 6520.I have an SSD in this thing and was getting close to 6 hours with the OEM 9 cell that was well used prior to the SSD.I was disappointed to put this guy in and after several cycles, the best I can do is about 2 hours, which is a bit unacceptable seeing as the description says 2 hours, which I need to believe is with a conventional platter HDD.I'm wishing I would have just chalked up the extra money and got an authentic Dell 9 cell elsewhere on the net.
