Li-ion batteries has a nominal voltage of 3.7 Volt and the maximum voltage is 4.2 Volt. About the minimum voltage consider that li-ion chemistry charge discharge reaction work in a range of 3 to 4.2 volt maximum. In this region this reaction is pretty reversible. this mean that if we put an amount of Energy inside the battery, the battery will be capable to provide this energy at the output with only a little loss (due to thermic resistance). However, when the li-ion cell voltage drop below 2.9, 2.8 Volt chemical deterioration occurs among the anode and cathode so the charge-discharge reaction is no more reversible and the battery start dying. The reason because this trick seems to work is because the chargers usually has a protection mechanism the work measuring the battery voltage and if this voltage is under 3 volt the charging chip does not give consensus to start current flow. This because forcing a current into a damaged battery can lead to produce gas leakage and sometimes to explosion. So charging a defective battery is "DANGEROUS". When a consistent voltage is applied to the battery terminal (Costant Voltage from a power supply as in this case) the battery voltage rise for a short time over 3.1 Volt and in this case the charger is somewhat fooled and think that this battery is simply at the low end of a normal charge region and start to charge. it is possibile that in some case the battery will be charged but if you measure with a professionali lithium charger the amount of energy the battery is capable to store before it reach the full 4.2Volt end voltage you will find that this will be very far from the nominal battery capacity. If you have a 3300 mAh battery it means that you can drain from the battery 3.3 Ampere for an hour ... or 330 mAh for 10 hours. Insted when you charge a defective voltage the amount of current will be sensibly lower .. ex you can drain only 100 mAh per 1 Hour or less, if you are lucky that the battery does not exploded during the charge process. BTW there is way to improove batteries that are close to their end lifecycle using a pulse charging technique, but this is available only with professional charger and not the simply one seen on video. In this case the battery if charged using pulses of short duration with high voltage ... this lead to a sort of chemical shock to anode and cathode and in a certain sense "clean-up" the electrodes restore the battery chemical charge-discharge cycle. However this only work for battery that are still quite good and not for battery in low discharge. In addiction this professional chargers usually monitor also the battery temperature and block the charge process if the temperature is rising over a safety value.

Und deswegen sollte man nicht solche schwachsinnige Video veröffentlichen "Ihre Batterie hält ewig". Aber hier geht es eh nur darum Klicks zu generieren.
From experience, I found it is difficult to revive dead Li-ion cells. Many advice that the top be punctured to release gases inside the cell. This works for a short time only. Li-ion cell has a certain charge-discharge cycle. The chemicals and Lithium used deteriorate with each cycle.There is heat produced inside while drawing of power. It is not worthwhile putting effort and time to get dead cells into working condition. Reconditioned cells will discharge very quickly and will not provide the amperage needed for running devices. Li-ion cells can easily catch fire if you tamper with it.

Thank you for watching and leaving a comment. Regarding the issue you raised, I haven't conducted specific measurements. After receiving your question, I checked the two repaired batteries using a flashlight. One battery still works normally, while the other one drains faster.

No kdoví... Baterie z pochybného obchodu se štítkem 6800mAh měla po změření 800mAh. Takto opravené budou mít podobné parametry. Pokud alespoň udrží napětí, lze ji použít tam, kde není velký odběr. Nebo se smířit s velice častým nabíjením. Ale jde o nouzové řešení, nakonec to vždy skončí nakoupením nových článků, nebo celého zařízení. A naprostý nesmysl je kombinovat takto zachráněné články do větších baterií. Rozdílná kapacita jednotlivých článků způsobí, že baterie bude brzy nepoužitelná.

I think you are mistaken. The battery was not completely dead, just very discharged. The battery will suffer progressive damage if the voltage is allowed to become too low. The only problem was the charger refusing to charge the battery, because the voltage was very low.

sometimes the battery short circuits and if there are other parallel batteries it causes thet other batteries damaged.ithis kind of scenario happened me several times.if the battery is completely dead no chance to resurrect. or very redeced caoacity. Delta peak charger can be tried if battery is not completely dead and i will design for my weak batteries.

Disagree. This lets you charge the battery/cell. THEN you can look at its capacity. Capacity testing in these examples is of limited value because the result depends critically on the history of the battery itself. So it's not generalizable to OTHER BATTERIES!

Bei kurzzeitigem Anlegen von 5 Volt geht die Spannung des Akkus über die min.-Spannung des Ladegerätes, so dass er wieder geladen werden kann. Allerdings bilden sich Dentriten, welche dann die berüchtigten Kurzschlüsse mit fatalen Explosionen verursachen können. 💥

I have been researching this for months, the most shocking thing is that MANY computer batteries 'die' with only one 'duff' cell. If you build a Li-ion charger you can revive dead cells enough to make them useful. It's amazing how long Li-ion cells can hold a charge for, much better IMO than retail rechargeables like NiMH for example.

There's a safer way than hacking away at charger cables(!). Use an Imax B6 or similar smart charger, switch it into a 3 or 4-cell NiMH/NiCd mode and set the charge current low (0.2A for example), connect and start charging your Li-Ion cell and monitor the voltage; It shouldn't take long until it rises to around 3V, at which point stop charging and switch charging modes to regular Lithium-Ion. Then you can charge it back up to ~4 volts and may get some limited use from the battery in low current applications, although the cell will have degraded from discharging too low like in the video.

While it's counterintuitive, Undercharged or discharged , (not overcharged) Li ion batteries are unstable. I hit an old cell phone dead battery with a hammer once, and it burst into flames - that's a repeatable experiment. There is a small "circuit breaker" at one end of the battery that shuts the battery down if it gets too hot, or too undercharged - when you can get thermal runaway. If you damage that board, good luck.

You could have saved alot of messing around and used the multimeter to do the same thing as the cut up usb charger, put it on the continuity test setting and force a bit of power into it that way. Thats all i do when batteries are too glat to take a charge.

Watched this carefully several times. The captions are small and not on screen for long enough. I have tried this "splash" technique and it did not work for me on Lithium cells. It works for Ni-Cads and to some extent Ni-Me-Hy types where the heavy current blows away (melts) the dendrites that have formed within and are shorting out the material. I didn't find lithium to be the same or redeemable with this technique. Your comments please. There is another issue: That of capacity. Restoring the voltage is only one part of what is required, Does the cell have lasting charge. Can it deliver a high current? More comments please. BjG

About the minimum voltage consider that li-ion chemistry charge discharge reaction work in a range of 3 to 4.2 volt maximum. In this region this reaction is pretty reversible. this mean that if we put an amount of Energy inside the battery, the battery will be capable to provide this energy at the output with only a little loss (due to thermic resistance). However, when the li-ion cell voltage drop below 2.9, 2.8 Volt chemical deterioration occurs among the anode and cathode so the charge-discharge reaction is no more reversible and the battery start dying. The reason because this trick seems to work is because the chargers usually has a protection mechanism the work measuring the battery voltage and if this voltage is under 3 volt the charging chip does not give consensus to start current flow. This because forcing a current into a damaged battery can lead to produce gas leakage and sometimes to explosion. So charging a defective battery is "DANGEROUS". When a consistent voltage is applied to the battery terminal (Costant Voltage from a power supply as in this case) the battery voltage rise for a short time over 3.1 Volt and in this case the charger is somewhat fooled and think that this battery is simply at the low end of a normal charge region and start to charge. it is possibile that in some case the battery will be charged but if you measure with a professionali lithium charger the amount of energy the battery is capable to store before it reach the full 4.2Volt end voltage you will find that this will be very far from the nominal battery capacity. If you have a 3300 mAh battery it means that you can drain from the battery 3.3 Ampere for an hour ... or 330 mAh for 10 hours. Insted when you charge a defective voltage the amount of current will be sensibly lower .. ex you can drain only 100 mAh per 1 Hour or less, if you are lucky that the battery does not exploded during the charge process. BTW there is way to improove batteries that are close to their end lifecycle using a pulse charging technique, but this is available only with professional charger and not the simply one seen on video. In this case the battery if charged using pulses of short duration with high voltage ... this lead to a sort of chemical shock to anode and cathode and in a certain sense "clean-up" the electrodes restore the battery chemical charge-discharge cycle. However this only work for battery that are still quite good and not for battery in low discharge. In addiction this professional chargers usually monitor also the battery temperature and block the charge process if the temperature is rising over a safety value.

EXACTEMENT
Und deswegen sollte man nicht solche schwachsinnige Video veröffentlichen "Ihre Batterie hält ewig". Aber hier geht es eh nur darum Klicks zu generieren.
Wow, this works like magic! Who else is going to give this a shot?
From experience, I found it is difficult to revive dead Li-ion cells. Many advice that the top be punctured to release gases inside the cell. This works for a short time only. Li-ion cell has a certain charge-discharge cycle. The chemicals and Lithium used deteriorate with each cycle.There is heat produced inside while drawing of power. It is not worthwhile putting effort and time to get dead cells into working condition. Reconditioned cells will discharge very quickly and will not provide the amperage needed for running devices. Li-ion cells can easily catch fire if you tamper with it.
Thank you very much for your helpful advice. I really hope to continue receiving your feedback and suggestions for my future videos. Wishing you and your family happiness and peace. Best regards!
What?? Do not puncture a lithium ion battery, they catch fire if oxygen gets into them.
You have answered my hasty questions. However, I'll leave it there. My experience exactly like yours. A lot of wasted time and energy!
@@scotthenry3401 I completely agree with your point of view; we shouldn't interfere too much with the battery.

Appreciate your efforts, but want to know for how long the "repaired" battery maintained it charge at a constant level. Thanks for the experiment.
Thank you for watching and leaving a comment. Regarding the issue you raised, I haven't conducted specific measurements. After receiving your question, I checked the two repaired batteries using a flashlight. One battery still works normally, while the other one drains faster. I believe this may depend on the remaining quality of the battery. I truly appreciate feedback like yours and hope to have your support in future videos. Wishing you and your family happiness and peace!
No kdoví... Baterie z pochybného obchodu se štítkem 6800mAh měla po změření 800mAh. Takto opravené budou mít podobné parametry. Pokud alespoň udrží napětí, lze ji použít tam, kde není velký odběr. Nebo se smířit s velice častým nabíjením. Ale jde o nouzové řešení, nakonec to vždy skončí nakoupením nových článků, nebo celého zařízení. A naprostý nesmysl je kombinovat takto zachráněné články do větších baterií. Rozdílná kapacita jednotlivých článků způsobí, že baterie bude brzy nepoužitelná.

I think you are mistaken. The battery was not completely dead, just very discharged. The battery will suffer progressive damage if the voltage is allowed to become too low. The only problem was the charger refusing to charge the battery, because the voltage was very low.
Thank you for watching the video and leaving a comment. I hope to continue receiving your support for future videos. Wishing you and your family happiness and peace.
I would discharge all cells to 1.10 volt so they are all even then recharge. 2 Si diodes and a resister in series.
sometimes the battery short circuits and if there are other parallel batteries it causes thet other batteries damaged.ithis kind of scenario happened me several times.if the battery is completely dead no chance to resurrect. or very redeced caoacity. Delta peak charger can be tried if battery is not completely dead and i will design for my weak batteries.

Without a capacity test, this is just a useless exercise.
No its work good .
It works. So far I always got a success in the process.
@@dattatrayavaidya4442 I am sure the process will kickstart the battery again. Yet, without a capacity test it is pretty meaningless
Disagree. This lets you charge the battery/cell. THEN you can look at its capacity. Capacity testing in these examples is of limited value because the result depends critically on the history of the battery itself. So it's not generalizable to OTHER BATTERIES!

Bei kurzzeitigem Anlegen von 5 Volt geht die Spannung des Akkus über die min.-Spannung des Ladegerätes, so dass er wieder geladen werden kann. Allerdings bilden sich Dentriten, welche dann die berüchtigten Kurzschlüsse mit fatalen Explosionen verursachen können. 💥

I have been researching this for months, the most shocking thing is that MANY computer batteries 'die' with only one 'duff' cell. If you build a Li-ion charger you can revive dead cells enough to make them useful. It's amazing how long Li-ion cells can hold a charge for, much better IMO than retail rechargeables like NiMH for example.

There's a safer way than hacking away at charger cables(!). Use an Imax B6 or similar smart charger, switch it into a 3 or 4-cell NiMH/NiCd mode and set the charge current low (0.2A for example), connect and start charging your Li-Ion cell and monitor the voltage; It shouldn't take long until it rises to around 3V, at which point stop charging and switch charging modes to regular Lithium-Ion. Then you can charge it back up to ~4 volts and may get some limited use from the battery in low current applications, although the cell will have degraded from discharging too low like in the video.
Oh, I've learned some wonderful experiences from you. What you said really surprised me, and it has given me more knowledge about this. Thank you for watching the video and leaving a comment.

While it's counterintuitive, Undercharged or discharged , (not overcharged) Li ion batteries are unstable. I hit an old cell phone dead battery with a hammer once, and it burst into flames - that's a repeatable experiment. There is a small "circuit breaker" at one end of the battery that shuts the battery down if it gets too hot, or too undercharged - when you can get thermal runaway. If you damage that board, good luck.

You could have saved alot of messing around and used the multimeter to do the same thing as the cut up usb charger, put it on the continuity test setting and force a bit of power into it that way. Thats all i do when batteries are too glat to take a charge.

Watched this carefully several times. The captions are small and not on screen for long enough. I have tried this "splash" technique and it did not work for me on Lithium cells. It works for Ni-Cads and to some extent Ni-Me-Hy types where the heavy current blows away (melts) the dendrites that have formed within and are shorting out the material. I didn't find lithium to be the same or redeemable with this technique. Your comments please. There is another issue: That of capacity. Restoring the voltage is only one part of what is required, Does the cell have lasting charge. Can it deliver a high current? More comments please. BjG

من سوريا وانت؟؟❤
Oh, I have a friend from Syria. I really admire your country, and I hope that one day I’ll get the chance to visit and see ancient cities like Palmyra, Bosra, and the Umayyad Mosque. I’ve known about Syria since I was a child. We used to play a game published by Microsoft called Age of Empires, and that’s how I learned about Palmyra as one of the most powerful empires in history. I'm in the US . Thank you for watching the video and leaving a comment. I hope to continue receiving your support for future videos. Wishing you and your family happiness and peace.

Film pokazuje głupiego hura optymizm, taka naprawa sprawdza się może w 10-20% . Często bywają ogniwa z zwarciem i nie pomoże im nawet podłączenie do akumulatora czy zasilacza 12V a pojemność obudzonych ogniw sięga ledwie kilkanaście % sprawnego ogniwa. Na filmie widać🤭że latarka ledwie świeci na tak cudnie ożywionej baterii

I have already used such a procedure, however, batteries charged and renewed in this way last less and must be charged more often. Greetings from Serbia.
