    Most probably already know this :

    Have a dead battery that wont charge because it was drained totally?

    Take a charged battery and jump connect the leads to the dead one for about a minute.
    Place the dead one on the charger and it should recognize and start charging.

    Not advisable with LiON batteries. They are totaled if over discharged.

    At best it will be an unpredictable battery. At worst it will catch fire / explode.

    I couldn't get this one to charge after it was drained. It seems to work just fine now.
    It didn't get hot during the charge and doesn't get any warmer than my other batteries after use.
    It isn't an old battery and wasn't damaged.

    Marked it so I can keep an eye on it.

    This is what you get with a questionable battery...

    My concern here is that there are lot of new forum members since Xmas.

    It may be they are not up to speed with the potential dangers of LiPo batteries.

    To those folk [especially] I would say- totally ignore this suggestion :shock:

    I rechecked the battery on charge and decided to follow your advice. It was charging up but looking at it I see that it has ballooned ever so slightly.

    Marked it red and will trash it.

    One would think with the possible hazards there would be a prominent warning about this by phantom .

    Thanks for stepping in !!

    It's advisable not to discard a charged battery--discharge it with a 12v automotive light bulb and then discard in accordance with any hazardous waste laws in your jurisdiction.
