Purchased this for an XPS 15 9560, as the original battery has degraded and now holds 50% of capacity after 2.5yr of heavy use (multiple full drains every day). Came with ~60% charge, appears to charge/discharge just fine. Full capacity for mine is 91,588 mWh; for comparison, the original battery came with 89,513 mWh, and the designed capacity is 97,003 mWh. (Use Powershell > "powercfg /batteryreport" to find data) The power connector wire was a bit longer than original so I had to squish it to fit, just be careful!
P.S.: I stripped one of my battery screws while trying to remove the original battery, and never bothered to put it back in. It's fine if you leave a couple of screws out, just make sure to distribute the screws evenly around the battery casing to compensate.
