On this Dell D620 laptop, when I looked at the Power Meter in the Control Panel, it showed 6% and still the same this morning so how I can know for sure without having to purchase and try another battery whether it's the battery at fault or the system is not charging it?

You can test the voltage on the adapter.

 

If you are able to run the laptop without the battery, without any issues, then its probably the battery.

You can test the voltage on your adapter (charger) with a multimeter. If it is not reading the correct voltage (specified on the info on the power block) then it will not charge the battery.

 

Sometimes adapters will fail- but as I stated if you can run the laptop with the adapter only it is probably not the adapter that has the issue.

Ok, thanks for explaining, yes, I just purchased a new adapter for this unit so I would rule that out, I was thinking there might be some sort of utility which can tell if a battery is at fault?

Also calibrating your battery will help give accurate readings.

Under Battery Health in the BIOS it is showing :

 

Primary

This battery can no longer provide sufficient power to your system and needs replacing.

 

BUT, the Battery Info is showing "charging" 24% and now climbing as I write this?

You can also run Dell Diagnostics on it.

 

Sounds like the battery is failing, yes, and probably unstable based on your latest post.

Well I don;t understand, why it suddenly started charging all of a sudden and now it's fully charged to 100%

Oh, I started playing a video to see how long the 100% charge would last, after only 2 minutes, the pc shut down so can we say that it's a bad battery since the system had charged it to 100%?

Try doing the calibration that I posted in the link. If that doesn't work and the pc is still shutting down due to inaccurate readings, then yes the battery is at fault and needs to be replaced.
