How do you know when battery is fully charged?

Thanks for the correct information.

This is the reply I received from a SanDisk Tech Rep.

Thanks for emailing SanDisk Technical Support. It is our goal to make sure you have all the resources you need to get the most from your product.

I understand that you don’t want to over charge the battery of your sansa players. I would like to inform you that when the battery is fully charged it will show you a message “charge complete”.

I knew he was wrong because I have been charging 36 Hours & no “Charge Complete” message yet.

Thanks Rick 4q
