    Suddenly dead battery question

    Hi all, I noticed my mod getting hot in the pocket. Pulled it apart and let the 18650 cool. Checked it, and it is completely open circuit. No volts, no resistance. Obviously dead. Fitted fresh battery, and mod works fine.

    Does this usually happen? It was fine half an hour ago.

    A Gatling VW/VV mod with all the usual bells and whistles. If it was a pocket fire, it should have stopped after 8 seconds I think? I just checked and can confirm this feature working....

    Check to see if there is any insulation damage to the heatshrink on the battery , possibly if there is you had a dead short happening ?
    Its pretty rare for a battery to just spontaneously crap itself , its usually due to an external short somewhere , or in even rarer cases if the battery had been previously abused somehow and has managed to give itself an internal short ?
    Manufacturers defect also possible but thats in "hens teeth" figures usually ?
    If its a protected cell , it could be that the protection circuitry has tripped and that's why you are getting 0 readings from it ?

    Hey FM,

    It was one of those batteries I won from that comp you ran a year or so ago, Pana NCR18650PF so can confirm a known brand battery. Dunno if it's protected ?

    no insulation damage, no obvious over heat marks or anything.

    Only abuse has been continued usage for the past 12 months in multiple mods.

    all good - time to order another.... or two

    LOL those Panas are available in protected and unprotected as far as I know ... if the protection circuit has tripped , just try putting it into a charger for a few minutes and see if it resets , keep an eye( and feel) on it... could be it somehow had a short and tripped the protection
    But if its an older cell and has served you well ,its probably time to retire it
