New Laptop Battery is Not Charging

I purchased a Dell WDXOR replacement battery for my Dell 13 inch touch-screen laptop. The actual replacement when seamlessly. The directions from iFixit stated to let the battery charge fully (and continue charging at least two hours beyond full). Then it stated to run the laptop on battery power until the battery is exhausted then fully charge again.

I had the laptop charging all night and woke up to it only 7% charged. I checked the charging cord and it appears to be working but the battery is not charging (or charging extremely slowly). When I unplug it from the charging/power cord it immediately goes into low battery mode.

Did I do something wrong or does it take several days for the first charge of a new battery?

Thank you,
