Anyone who is reading this review has got to be really disappointed in Razer. There's no excuse for battery in a $2500+ laptop to EVER bulge. The fit was perfect and my laptop appreciated the reduced stress the previous portly battery was causing. The install was fairly easy. You should be comfortable with disassembling tech. Be sure to find a good YouTube video to guide you through the process. So far the battery has worked flawlessly: keeps it's charge, doesn't overheat, and so far no signs of bulging. Great value.

Worked right away. Good price

excellent product just as discribed

Exactly what I needed right when I needed it no fuss or multiple questions

Without power saving settings none of these batteries will go mobile for more than a few hours. This battery was just as good as the original Dell battery before it had issues. If it keeps going for a few more years then it was worth the cost?

It worked well, it came promptly at a fair price.

Like another review said, the ribbon cable is just a bit too long, but after some careful adjustments to it, there's no stress on the connection at the motherboard. The battery fits well otherwise, all screw locations line up perfectly. Considering the Razer battery was so bloated that it was difficult to get the cover off, this battery is a very welcome replacement. Time will tell if it holds a charge well, but so far it's charging and discharging at a steady, expected rate.

Battery health is not great for a “new” battery Battery health came in at 71% Design capacity is 41,440 mwh Full charge capacity 29,600 mwh
