Hello list: Nearly two years ago, I bought a JBL Flip 4 speaker; is a
good-sounding speaker for its size and have used it a lot here of late!
When I first became aware of this speaker, I had heard that it would give up
to 12 hours of battery life! However, am finding now that it doesn't give
that much! The bad thing is that it gives no verbal warning when the
battery is getting low! Fortunately for me, I have enough vision that I can
see a red light blinking when the battery is starting to get near where the
speaker will shut off! My question is, can these batteries be replaced? Or
is it as I am suspecting: that thing is designed in such a way that there is
absolutely NO WAY to open it up and replace the battery? I have often just
run it with the speaker plugged into electric; could this caused it to lose
its battery life? Thanks for any info you may be able to provide!
