Since I asked this question about the Radio Shack "Portable CD Player Power
Pack" (23-505) rechargeable lead battery, I have gone ahead and used it
with the 722. The unit functions quite well except that the "battery
charging" indicator never goes out. So it would seem that the internal
battery is not being charged, at least not effectively. So, does that mean
that it is possibly being discharged while the external battery (3 - 4.5
nominal voltage) is attached?
How does the Sharp prioritize battery drain anyway? If, for example, I have
the Sharp battery pack installed and a freshly charged internal battery,
which is the primary current supplier to the unit?
Thanks for all the info thus far.
