Hi Sandra, I've only had my BC for a short time and only got through two sets of batteries so far: the alkalines supplied with the BC and my rechargeables. The batteries that came with the BC went directly from 39% to "change battery". This has led me to ignore the charge indicator for any batteries. Its interesting to hear that yours goes down to 5%. I do mainly play mp3 files.

Now, though, since all this talk about BC's dying when the batteries are changed, I usually change them when my batteries are at about 5 per cent, just in case! Cheers, Sandra.
