Plugged In, Not Charging

I recently replaced my battery for my Dell Latitude 6520.  After installing the new battery, the battery began to charge.  It stopped charging when it reached 57% and the battery icon indicated battery plugged in, not charging.  After researching this issue, I have tried various fixes noted in the Dell Forums.  Incrementally, I have been able to get the battery to charge to 63% before it gives the plugged in, not charging status.  I have update the BIOS and the adapter is recognized properly.  I also uninstalled the Microsoft A/C Adapter and Microsoft ACPI-Compliant Control Method Battery (3 are listed) drivers, re-installed the drivers, and check for updates for any of those drivers.  All drivers are up to date.  To summarize:

1. Installed New Battery that Dell Battery Information displays Health as Excellent

2. A/C Adapter is recognized and will charge battery up to 63% (originally would only charge to 57%)

3. All Battery related Drivers are up to date

Any suggestions are appreciated.
