Thank you so much, you just spared me from having to buy a replacement battery for my Canon G9. I used three AA batteries and RCA cables as makeshift wires, and it worked like a charm.
I had an extra brand new Olympus Li 50B battery that I stupidly was saving, and it would not charge. I did the exact same thing in this video and was able to get enough voltage into the battery to charge again. Thanks!
I just tried this with a bad Olympus Li-10B battery, in 20 seconds it went from 0.2 to 3.1 volt and now it is charging. Thank you for showing this method.
I'm happy to hear that you got your battery back up and charging. Just remember, if a battery reaches a very low charge level then this method will not work. An example that I can give is a 18V drill battery, I managed to bring it to life once with this method, but then some one drained it too much and even this method didn't help and the battery had to be disposed.
Great video! I got an amazing deal on a C100 ii on MPB. It was so cheap because it had a non-functional battery, and was missing accessories. Long story short it came with all accessories still in packaging. Only the Battery did not work. I used a third party battery from Amazon to jump the dead battery and now I have 2 fully functional batteries! Great advice and video. Thank you!
So basically it's the charger that refuses to charge if the terminal voltage drops below a threshold. ~2V in this case happened to be below the threshold so the charger wasn't doing anything. You bypassed the charger logic and forced it to accept charge from another battery for a few seconds.. and voila, terminal voltage at least temporarily went above the threshold and charger started charging again. I am going to try on my Lumix S1 battery and let you know how it goes. I don't have a multimeter though, so I will just connect the batteries in parallel.
That is exactly it, you did a better explanation than I did. As for why that happens, battery chargers have some kind of a failsafe to prevent either damage to your devices or missuse.
Thank you for the video. I'm trying to revive a dead (and crazy expensive) Canon bp a60 with your method. I have 2 batteries, one charges and works, the other one drained out won't charge. The doubt I have is about the connectors, since this battery apparently have 2 for + and 2 for -. I'm trying to jump start it but the charger still refuse to charge... Do you have any advice about the connection for this battery? Should I leave the other one connected longer? Thank you so much for your support 😊
Thank you for the feedback and the question. I do see the battery is different than the usual suspects. I can't say for sure how the connectors are wired since the total voltage is listed as 14.4v. if you have a multimeter you could check if the output between the different +/- pins is 7.2v or 14.4. if output is 14.4 then it doesn't matter which pins you use to charge it, if the outputs are 7.2v, then it means you'd have to charge the 2 packs that are inside the battery individually.
@@JackallDigitalthank you so much for the answer, I suspect that they split the voltage between the two, therefore could I use two cable for + and two cables for -? I'll try some tests, thank you again!!
You can definitely use 2 and 2 cables, I just don't know how finicky it will be to hold in place, but there's only one way to find out so let us know how it goes.
Let's see if I understand you correctly, you want to power the camera with the battery using cables, like a dummy battery of sorts? If that is the case then you could probably do that with cables if you managed to hook them or fix them to the camera pins. However, some cameras have 4 pins. One pin is for displaying battery level, you don't need to connect this pin, but the other pin is for battery temperature - you need to connect a resistor to it. Assuming that works, the camera also needs a hole of some sorts for the cables to go out to the battery or external power supply. If I misunderstood, please explain a bit more what you meant. As for the connections, you always connect negative to negative and positive to positive, even if you are using cables.
I don't have any experience with NPF batteries, but if it is empty and not charging then you have nothing to lose by trying this out. For a good measure you could do it outside in case you'd need to throw the battery into an open space.
I had a short piece of multi strand wire that had solder on the ends. It doesn't matter if it is a single core wire or a wire with multiple copper strands. The only thing that you need to make sure is that you have a good contact on the batteries and that the wire is not too long.
I see that the terminals for this battery don't have easy access. If you have some wire that you could put in that would be the best. The second option would be to use some metal strips - you could use aluminium foil. Third option would be to take a thicker copper wire and hammer the end of it down to get a "plate".
Tried it with Sony F990T battery that will no longer charge. Nothing the first attempt for a few seconds. Trying it again. It has been connected for about 5 minutes now. the connection is draining the host Sony F990T, but the dead battery is not accepting a charge. I am thinking that the dead battery is just way below the minimum charging level. Should I continue the connection for a longer period of time?
I took a quick look at the battery and it looks like a beast. I'm guessing the battery itself might have some kind of its own charge protection. The only thing that comes to mind is to try and charge it with another source. A 9V battery should suffice, though of course you would ideally have a power source that is 10% higher than the battery rated output, so for a 7.2V battery you'd want an 8V power source, but there are no readily available 8V DC power sources. I hope you get it working because I see they're quite expensive.
One battery was good and the other was not. I used the good battery to bring the faulty one back to life. Similarly to how one can jump start a car battery. Both batteries still work just fine to this day.
@@JackallDigital i guess you just have to carefully slowly say it like others do and then when u have nailed it, try to say it faster. Just a guess tho
OMG.... you are really genius. I tried on Nikon EN-EL 15, I succeed after 3-4 attempts, its working perfectly fine. Thank you so much.
I'm happy to hear that you got your battery back up and running
Worked great for my Artman LP-E17 batteries. Flashing red lights on the charger. I hadn't used them in a year. This brought them back to life. Thanks!
That is great to hear. You should use them more frequently so they don't dry up!
Thank you so much, you just spared me from having to buy a replacement battery for my Canon G9. I used three AA batteries and RCA cables as makeshift wires, and it worked like a charm.
That's great to hear. And it's good to know that your diy solution also worked!
Where did you get the RCA cable from?
I had an extra brand new Olympus Li 50B battery that I stupidly was saving, and it would not charge. I did the exact same thing in this video and was able to get enough voltage into the battery to charge again. Thanks!
That's great to hear! But I'm wondering, does that also mean the original battery lasts very long so you had no need for the spare?

Worked for my Fujifilm XA3 batteries! Thank you so much!
That's what I like to hear. Happy filming/photo shooting

This worked for my Fuji X100V battery! Thanks a bunch sir
That's great to hear!
So how would you use the batteries? You have them neg to pos with cables at the end connecting to the camera battery?

Genius...worked for me.....nust subscribed......👍👌
I'm happy it worked for you
worked for me , manythanks!
That is great to hear
Worked for my Fujifilm XT4's batteries. Thanks a lot 👍🏽👍🏽👍🏽
I'm happy to hear that it worked for you
Does this work for NPF batteries?

Thanks so much. Looking forward to trying this on my sony zv-10
I hope it works out!
Gonna try this on one of my lumixs1 batteries that's not charging and hopefully it will work..what kind of wires did you use.?
I had a short piece of multi strand wire that had solder on the ends. It doesn't matter if it is a single core wire or a wire with multiple copper strands. The only thing that you need to make sure is that you have a good contact on the batteries and that the wire is not too long.
Hi, what kind of cables do I need?
There is nothing specific about the cables, maybe the only thing is that the wires are thick and firm enough for you to hold on the contacts
I used the 5 AA and my 2 test leads for my old cannon lithium. I can’t believe that worked. It’s charging now!
That's great to hear. I hope it serves you for a long time!
This is great, thank you!
I'm happy to hear that!
hi, how can i do the same to lp-e5 because this battery has different connector so I can't just plug wires in them
I see that the terminals for this battery don't have easy access. If you have some wire that you could put in that would be the best. The second option would be to use some metal strips - you could use aluminium foil. Third option would be to take a thicker copper wire and hammer the end of it down to get a "plate".
@@JackallDigital thank you so much, I'll try it right now!
@mips693 if you use the foil don't forget to fold it a few times so it's thicker and easier to work with
@@JackallDigital noted!
@@JackallDigital no, nothing helped, I've tried everything but unfortunately, but thank you for a help!

Thank work worked perfectly!!

@@JackallDigital honestly could not have worked better, thank you 🙏
holy shit thank you very much! i revived an old 6V battery with a usb cable and a 5V 1A supply
That is a little bit strange but it's great to hear that it worked for you even with a lower voltage. So thank you for sharing your experience.
I'm going to try it on my xa11 batteries...hope it works for me. Thanks
I hope you had success with your batteries
That's genius 🤯🤯 thank's
You're welcome :)
Hvala puno 🇭🇷
Nema problema
But whats happened with other battery ?
One battery was good and the other was not. I used the good battery to bring the faulty one back to life. Similarly to how one can jump start a car battery. Both batteries still work just fine to this day.
OMG.. it worked for me with Nikon ML battery.. holy cow
Worked for panasonic pv-l559
That's great news, thanks for sharing
Why do you stutter on the letter "R" like that
I never learned to pronounce letter R when I was young, but if you know of any good video that will let even me learn it, I am all ears.
@@JackallDigital i guess you just have to carefully slowly say it like others do and then when u have nailed it, try to say it faster. Just a guess tho
almost lost hope ty man
Never lose hope, and your batteries :)
