kl Posted June 29, 2015 Report Share Posted June 29, 2015 (edited) I managed to totally empty one of my Li-Ion NP-1 batteries and now my charger (IDX) doesn't even make an attempt to charge it. Is there a chance or a way to re-animate my comatose battery? Tricks, techniques, voodoo ceremonies? tx ! Edited June 30, 2015 by kl Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted June 29, 2015 Report Share Posted June 29, 2015 First, let it sit a day or two and try again to charge it. Quote Link to comment Share on other sites More sharing options...

Christian Spaeth Posted June 29, 2015 Report Share Posted June 29, 2015 Someone once told me you can reanimate dead batteries (not just NP1) by putting them in a sealed plastic bag and then freezing them for a day, then let them warm up in the same bag and they're supposed to work as new.

Freeheel Posted June 29, 2015 Report Share Posted June 29, 2015 I've had good luck "un-tripping" the fuse in "dead" ipower 9 volts by giving them a quick touch to the terminals of another live nine volt. Never tried it with an IDX NP1, but it seems like a worthy thing to try. If you google "dead lithium battery" you will find a fair bit of info on how batteries can go into a shutoff mode if they are overdischarged. Sometimes just giving them a quick jolt of power at the proper voltage (the same voltage they output) will reset the overdischarge shutoff.

Tom Duffy Posted June 30, 2015 Report Share Posted June 30, 2015 Agreed, with AA batteries that have been dischanged in a flash light left on are too low to be charged in a smart charger, I put them in parallel with a good battery for 5-10 seconds, then quickly put it into the smart charger where it will register a voltage again. I sometimes wish I hadn't thrown out the "dumb" charger that was just a constant current source. The NP1 should be similar, needing a way to jump start the process. An older NiCad NP1 charger (Sony models for $20 on ebay) might do the trick, but I bet the IDX would be warranty voided because of using a non-approved charger.

Jack Norflus Posted June 30, 2015 Report Share Posted June 30, 2015 Zack from IDX is on this forum - perhaps you can message him. Quote Link to comment Share on other sites More sharing options...
kl Posted June 30, 2015 Author Report Share Posted June 30, 2015 (edited) She's alive again! I was reading up a lot on the web - enough to get slightly confused of what to do. I let the battery rest 2 days, I put it in the freezer over night and some other esoteric stuff. I was hesitant to jump start/jolt it back to live by connecting it to a fully charged Np-1 - I'm aware of the explosive qualities of Lithium batteries - but that's what I did in the end. I taped two short pieces of solid electrical wire to one NP-1 and then touched the contacts with those cable endings of the dead one for about 5 sec after which I put it quickly into the charger. The charging light came on immediately and now, a few hours later the battery is fully charged. Thank you everybody for chiming in, the 'un-tripping the fuse' did the trick.

simon forbes Posted December 29, 2021 Report Share Posted December 29, 2021 Plus one on this hack. My Swit Np1 rose from the dead today. Thanks all. Sf. Quote Link to comment Share on other sites More sharing options...
Freeheel Posted January 2, 2022 Report Share Posted January 2, 2022 Glad to see this advice keeps giving! Cheers, Brent Calkin Quote Link to comment Share on other sites More sharing options...
Alien Posted January 4, 2022 Report Share Posted January 4, 2022 Was having a similar problem with the Li-ion battery in my Ambient master clock that got left switched on and drained way to much. It wouldn't hold a charge any longer and needed to be always connected to power. Went and worked a job in Green Bay this weekend where the temperature dropped to near 1 degree Fahrenheit then at the ned lo and behold it is now fully charged and working just as it always did. These these 'Happy accidents' Never too old to learn Quote Link to comment Share on other sites More sharing options...
