Flashing Red light, even though it is on the charging cradle?

Just after a few weeks of operation, my Bose Soundlink Mini Bluetooth's power led started flashing red, even though it was on the charging cradle. I didn't think much of it, since I thought it was not seated correctly on the charging cradle, so I lifted it off the charging cradle, and re-seated it back on the cradle again. The same thing happened after another week of usage. I repeated the steps I did during the first instance, and called Bose Technical Support yesterday. They claim there is nothing wrong with the unit, and that the power led would first turn yellow before flashing red. I admit, I have not been staring at the unit all the while I use it, but I have never seen it display yellow. Bose Tech Support claims there is nothing wrong with it, but in my opinion having the same thing occur twice in a span of one month indicates that all is not right. Any advice in this regard would be helpful!
