I have heard fiio recommend u unplug and completley drain the batteries power once a month. They said this in the E17 thread. The only battery i know that is easily and supposed to be user replaceable is e11 the rest if you try, you could but would void warranty I THINK.I would send fiio a pm on head fi. They answer in 1-2 days and getting personal message is important
