I was wondering how the Fuze's battery holds up over the long term? I know you can't replace it, so it's something I've been worried about. New, it's amazing. 20 hours of audio? Wonderful. In a year or two though, will it be greatly diminished from your experiences?
I've owned a couple laptops in my time and, when left plugged in past a full charge, it's actually harmful to the battery's ability to sustain a charge resulting in less time between charges (over two years of plugged in use, my Compaq's battery capacity dropped by 50%!). I imagine it's the same thing with the Fuze, so I should only be charging it when it's almost completely dead and unplugging it right away, right? Are there any other "best practices" to maintain battery life?
Sorry for all of the basic questions. I bought the unit from Circuit City and it had very little technical documentation. Thanks in advance, I appreciate the advice!

"A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges."

Except the Fuze uses a Lithium-Polymer battery, not the Lithium-Ion as was used in the e200 series players. The Li-poly is like the Li-ion on steriods. Longer run time and more charge/dis-charge cycles throughout it's expected life.
You can read all about it here:

Lithium ion polymer batteries are basically lithium ion batteries. The polymer version can be thinner, and have a greater variety of shapes. They also might have slightly higher energy density than the non polymer variety.

Aren't the approved USB chargers rated at 5 volts? Several of the reference links off the Wikipedia page make reference to dangers (including fire) of charging lithium ion polymer batteries with chargers above the low 4 volts.

5 volts is the voltage going to the charger, not the voltage going to the battery.

I bought a Fuze (probably like a lot of people) because I lost my iPod nano and couldn't stomach paying a $50 premium for the Apple logo.
I've had a Fuze for about 6 months now...the battery life continues to amaze me. I use it almost solely for workouts and runs and charge it (honestly) rarely. I get about 5 workouts in a week and seriously charge it about twice a month. I have roughly timed it at about 20-25 hours and am also pleased that it is quite clear when the Fuze is shut off. Coming from a nano (which always seemed to be dead or just about dead), the battery life alone is enough to sell me on this player.

Sansa fuze is my 3rd Sansa mp3 player. I don't like having to charge connected to my PC. I purchased a charger by Griffin. It has a connection for the IPOD that is removable. Just remove that and the USB cable for the sansa fuze fits. Now you can charge anywhere that has an electricial outlook. The bonus is that you can listen to the player while it is charging.
