Here is such a general and simple question that I haven't seen an answer anywhere (let alone in my player's manual!): How do you best care for the battery?
Firstly I believe all of the batteries in use with MP4 players are lithium based, and therefore not susceptable to memory effects. I checked my battery but all I could see was basic information (in chinese) about the voltage rating. Can any one confirm that Lithium is the standard?
Secondly, what is the best way to charge up the battery? Should you just use it until it drains completely, or is it better to just charge daily, similar to plugging a cell phone in at night?
From my experience I've had trouble charging my player via USB connected to a computer. Maybe the current/voltage from my computer is not enough to give an adequate charge.
I've had much better success charging via a wall charger (included with the player, which has a USB output). This seems very reliable. However, I have a question:
When the light on the charger goes from red to green, does this mean that the battery is charged? I've noticed that in this case usually the battery indicator on the MP4 player still shows that it is charging. Should I just keep going or would that be a good time to unplug the charger?
One last question I have: Is it safe to leave the player charging, say overnight (for example 12 hours or more)? Is there any danger to the battery if I do this?
Maybe this question is not as simple as I thought...
By the way I did try to do my homework before posting. For those of you who have read through all of this I would like to share an interesting technical document I found on the internet:

This is good general information about lithium batteries, and gives me an idea about how to care for my MP4 player. However if anyone can provide specific answers to my questions I would greatly appreciate it!!
