I have tried to search for other posts on this but not found any.
I have had a D2-Boa since early 2009. It only sees occasional use, either on the go or next to my laptop.
Suddenly the other day when I took it out to use it, it wouldn't switch on. I was surprised since this has never happened before. I put it to charge. A few minutes later, I could start it. I used it and let it get a full charge (until the charging light went off). Then I used it on battery for an hour or so and turned it off.
The next day, again it was dead. This time it would not charge. After switching the amp on and off a couple of times, suddenly it did start charging, but only while the amp was on. Again I let it get a full charge. I then used it on battery (plugged in to USB but wit the charging switch off) for at least seven hours.
A couple of days later and I try to use it -- it's dead again. This time, it charges "fine" but even after an hour it wouldn't turn on. Fiddling with it while writing this post, about 2 hours after I started charging it, it suddenly works again.
So my suspicion is that the battery needs replacing. I have sent iBasso an email a week ago but not had any reply. I am based in the UK -- does anyone know where I can get hold of the 4.2V, 470mAh Li-Poly battery that I need? I can only find stuff on alibaba when I Google for those specs, nothing in the US or Europe.
Oh, and if anyone can show me how to get better search results on the forum, please do. I searched for iBasso D2-Boa battery, D2-Boa battery replacement, D2-Boa "battery replacement", etc.
