Recharge the battery when it's full

Hi,

I’ve recently acquired a CD Player with a USB port to connect my Sansa Fuze on. But when I connect it, it is as if I was recharging its battery, so I wonder if it is good to connect it to my CD Player when the battery is full. Is there a risk to affect the battery life ?

Don’t worry. The charging circuit should protect the battery.

But I don’t really understand why you are connecting it. Can you play the Sansa files through the CD player?

Yes, that’s it.

Thank you !
