I've noticed that my second unit's battery is starting to swell a bit. Time to swap it out.?
I think the batteries used on the copies of hugens unit are of low quality and are not lasting? as long as they should.? It might also be the counterfeit ip5303 charge controllers on some units as well...the ones that fail to sense load after a while and you need to add the power-on button to pin 5.?
YMMV

I had mine charged, and left it on the shelf for a few weeks and it died on me.
Seems to me to be some sort of high quiescent stand-by state possibly through the switch controller ?
Operating life, when charged and immediately used is good though, indicating the battery capacity as being about 400ma.
