Review on Replacement 97Wh Laptop Battery For Dell XPS 15 9560/9550 And Precision 5510/5520/M5520 (6GTPY) Compatible With I7-7700HQ And 5XJ28/I5-7300HQ (Longer Model, Not For SDD/HDD Laptops) by Bill Gomez

DO NOT BUY THIS BATTERY.I ordered one originally, and it was broken. My laptop would not turn out without the charger plugged in. Then I got a replacement and the replacement is also defective. The battery capacity is a lie, saying that full capacity is at 87w, but in reality, it drains in 30 mins. I have seen the battery percentage jump from 75% straight to 5%, and from 20% straight to 100%.This is happening for both windows and Ubuntu, and it tells me that my system isn't at fault here, the battery is the one at fault.If I could leave a zero star review, believe me I will.Worst purchase ever.
