How to revive a dead USB power bank battery pack

[@Prabuvirus]

Thanks for showing the Slim Sharp Blade Knife as the tool to open .

[@MaruyaSAg]

It’s great that your power Bank’s housing is very easy to open up. How can you do a small charge like what you did for a powerbank that can’t be opened up?

[@skywalkerair]

By using a low voltage charger, I was able to revive my battery. Thank you!

[@mrbr549]

Very informative video! This method also works well on cordless drill batteries that won't charge.

[@dreistein]

Thank you bro! For the accumulator lesson but also how to use my magnets 😄

[@nigelh3253]

Yeah, magnets was a neat trick!

[@newsgetsold]

Thank you very much! Exactly what I needed. I have a brand new power bank never used, but it's 4 years old so the internal battery🔋 had discharged and would not take any charge. Now it all seems to be working. I used Alligator test leads from a AA battery charger directly onto the internal battery.

[@paulklekot8774]

Thank you I learned a lot of good info from your video.

[@mariat8473]

Very informative shortcut method to kickstart a powerbank

[@k0m3n9]

Works for my old 13,000mah yoobao powerbank. Thank you!

[@OddASMR]

What a helpful video! Thanks. Could you do a video on how to use a voltage meter such as the one you have in this video please?

[@Daniel-dj7fh]

There are countless of videos out there, you always want to set the meter to measure the highest possible voltage and then click down till you are at the right level. If you know what the max voltage you can have is you can set it directly to the correct voltage. And you need to keep in mind that there is AC and DC, in case of the powerbank we have DC. But straight from the wall you want to measure in AC.

Ty bro!

[@user-mz6py1hg6f]

You're a genius, thank you 😊

[@XDM50]

Hey Vuaeco, Very good how-to video. Very helpful. Thank you. -Duane

[@chippywarren9706]

What a wonderful tutorial, thank you 👍

[@Daniel-dj7fh]

I have a powerbank which has not been charged for 3 years or so. The powerbank charges but I can only charge my phone about 500mAh instead of 2100mAh (given by the powerbank). Is there a way to fix this?

[@UmmNotQuiteSureToPut]

Ah, I remember this battery bank back when you did your video on the goal zero solar panel. Its had a long life. Haha

[@vuaeco]

Woa, you've got very good memory!

[@jerydob6499]

Hi. Good job on the videos btw. I have a quesrion: I want to join two dc power supplies , whose voltage and current vary a bit, in parallel into one output lead wire in order to charge my power bank; what is the best and/or most cost effective way to do this? Tyia for any good info. Grace to you.

[@Totogita]

I am from the islands and I love your videos they teach

[@MichaelLee-wh6rp]

fantastic videos. could i ask how you know which one wires are + or - if you use an old cell phonee charger?

[@cobrabassen9567]

YOU R O C K !!! Awesome Tricks for a Quick Fix !!

[@JoeUndercofler]

Great tip!!! This worked well for me!

[@WonsPhreely]

Thanks good video! I wonder how I could do it with the old phone charger? Also, you have a nice accent, where is it from?

[@tijuthomas809]

Thanks this video was a big help .

[@Superiorpowerwash]

Hello, do you think this would work with one of those lithium battery jump starters for a car? I bought one last year, charged it up and put it in the truck. I tried to use it last Friday and it was dead. I have tried to charge it but it only shows 0% and will not charge up. Any ideas? Thank you.

[@yauck1]

4:23 slap the key ring too lol...

[@iulian2548]

Thanks for the video. I have a 10Ah Intenso power bank that does not charge any devices in either of the 2 USB-A output ports. When I try to charge through the micro USB, the charging leds light up though, it shows as being almost full. Any ideas how I could fix it? It has been sitting unused for a couple of years if it helps.

[@pirluitpomer5812]

Thank you for the video. I have a Mophie power bank, it's new, but it's dead. Would you help me revive it? I can give you the details if you are interested in trying to revive it.🙂

[@teddyroxpin]

I have a powerbank with 8pcs 18650 batteries inside.. I didn't touch it for 1 year and now it won't take a charge. I opened it up... if I want to "jumpstart" or revive the batteries, do I need to disconnect all batteries and do them separately? or can I take another 18650 battery that I have and somehow jumpstart all 8 powerbank batteries at the same time? --- Do I connect positive to positive and negative to negative to jumpstart or positive to negative on each?

[@harrickvharrick3957]

brilliant! thanks!

[@safeersendjayawinata5553]

I have a similar battery pack that I just bought. I tried the same method and was able to get it from 0.81V to 1.60V but when I try charging it, the led indicator won’t turn on meaning it’s not charging. What should I do?

[@johnrhodes3350]

Repeat the jump start process and try to get the voltage up to 1.8V or even 2.0V sometimes that is the cut-off

[@IThinkNowListenUp]

What happens if you take rc 7.2v battery and try to charge a dead 18650 battery bank? Will the dead battery revive but the charging system that the 18650 is connected to get fried? I did just this and while I got the 18650 to record 4v from 0v after 30 seconds. I smelled other portions of the charging system burned. I have it charging now (outside in case it explodes) and it indicates charging but not exactly sure what the burning is from... (Cables or other)? Advice? Should I chuck it since unsafe now?

[@RoofRack2]

Very useful thank you.

[@jokinmyass9446]

I'm having the same problem. I think it's because I have short finger nails. Do you think it might help if I had long nail?

[@urgurl_candy]

How do I go about my 20000 mAh oraimo isn’t coming up or charging I don’t know if it got spoil due to over charging

[@chialee28g]

Thanks! This saved one of my dead battery bank!

[@eljanhajili]

I have the same Power Bank. But i have a problem. When i connect the phone to power bank it is fully charged), it charges for a maximum of half an hour, then the charging current stops and the Power Bank stops working. What can I do?

[@cheapfm]

Hi there I have a battery that shows 0 volts. Do you think i can still revive it like that? I heard that it might short circuit the good battery. Is that true?

[@vuaeco]

Hi Quang, that's not true. Short circuit is when you connect the negative to the positive of the SAME battery. Parallel charging method is not short circuit. You can still revive a 0 Volt battery. Most likely 0V batteries are dead as Li-ion cells do not like to be that much discharged. And to answer your other question about my KZbin user name, you are correct.

[@cheapfm]

vuaeco thanks for your answer :). So i tried reviving it like you but in fact it’s dead. What happened is that I was able to get it to about 1.2 V after 20sec attached to a working cell but the voltage kept dropping back down to eventually reach 0 V. Furthermore the battery kept heating up while discharging.

[@vuaeco]

quangvietkieu Two things that would hint you have a bad battery when you try this method: 1. The voltage drops too fast after you unplug the charging wires. 2. The battery heats up. These 2 things usually go together and that means your battery cannot be revived.

[@franklinnoelwillemse5734]

Thanks

[@khalid109q]

Nice &perfect.

[@treeolive4367]

What do i do if my power bank is charging but it does not charge my phone? Btw my power bank is the same as yours

[@80liverpoolfc]

Have you a link for the cable's? I'm gonna order some on ebay but don't know what they are called. Thanks

[@newsgetsold]

Alligator test leads

[@mokshagnaravikiran1559]

How much it's capacity bro

[@LeftOverMacNCheese]

Does it works with Li-Po battery?

[@mikejf4377]

Have you ever brought back a Ryobi 40V from low voltage, IE 18-22 Volts?

[@mikejf4377]

I do like your videos, most informative and interesting.

[@vuaeco]

I haven't tried a Ryobi 40V. I did try the 18V and it was a little bit tricky. The circuit board actually prevents you from parallel charging. So you will need to bypass the circuit board and charge the battery directly. I did a video on it a while back. You can find it in my video list.

[@chrisivandecastro4057]

sir what powerbank is that?

[@girl600podcast]

Magnet and batteries - can it explode if done wrong?

[@vuaeco]

Any batteries can have a potential to explode if done wrong.
