"battery life" is the normal American term but I see your point. How about
"How long should I expect the unit to run between charges?"
>>22. "Does the USB port supply enough power to run the FMR?"
>>During playback it is fairly close. While doing disc-intensive activities

Doh! I was thinking about being connected to the USB bus but without anything
going on. What I get for writing this while sitting in my restaurant and also
trying to talk to customers. Let's just delete that first sentence.
>>24. "how to I access the battery?"
>This is the typo I was mentioning ("to" for "do").
Thanks for the proofing.
