The advantage of rechargeable NiMH batteries are as follows:

Respectfully discussing:

  • much higher capacity. The Li-ion battery in my Fuze lasts 15-20 hours on a single charge, whereas one 2300mAh AA battery in my old i-River lasts over 40 hours, which is more than double the capacity. This was on you old i-river. How can you know what the charge/play time would be on the Sansa?

 

Fuze batteries I’ve seen for sale are 550 mah 3.7 volts.  So in total energy this NiMH is about 50% more (2.3 amphours *1.2 volts).  Note you can get higher capacity NiMH,
