Done the first Battery test on this player
I ran the player down completely and recharged using the supplied wall charger.
Total time to reach a full charge was
4 and a half hours.
So I let the player run overnight with the backlight set to
on all the time, playing mp3's random, at number 18 volume setting.
The player ran for
just over 7 and a half hours before it shut down.
I will do a test now with the backlight off, which is the standard test, but so far not bad at all, better than I thought.
