So I have an Astrolux MF01S with the extended battery tube and recently it wouldn't turn on after not having really used it in a bit due to moving. I put all the cells into my XTAR VC8 and one of the cells wasn't recognized by the charger. I used a multimeter and it's not reading any voltage from that cell (reads appropriate voltage from other cells). Is there anything to do or is this cell just dead for some reason? I believe they're the samsung 30Q's that are generally recommended.
