Hi,
Create a [https://www.windowscentral.com/how-check-your-laptops-battery-health-windows-10|battery report] to check the status of the battery.
When you have the report, compare the ''Design Capacity'' value versus the ''Full Charge Capacity'' value. For a good battery they should nearly be the same.
As far as I could find out a 1 long white, 4 short amber blink error code in Dell laptops means a bad battery.
You may just have got a bad replacement.
