This is the first thing that comes to mind for amateurs, but it only lasts for a while and there is a risk of Liquid leakage. Use rechargeable batteries. The best in the world is Panasonic's rechargeable Evolta, next up is Eneloop.

When I was a kid I found that I could do this with a wall wart and my cassette player. The batteries would charge up but not last last a day and then eventually started oozing acid.

Very dangerous and it can explode!!!

Never reproduce this at home fire danger single batteries cannot be recharged. This kind of video should be censored.

ok but the battery do not keep the new charge any longer, ! just test it after 1 or 2 hours after charging it, the voltage decrease fast , even if not working...

I don't have pvc pipe. can i use a really long piece of celery?

Wow... And as promised, this = soooo EASY!! With just twenty dollars worth of materials and a few hours' time you can save the $4 it would cost to buy 3 new batteries. Genius!! And those frankenbatteries are BOUND to hold a charge for at LEAST an hour or two! Next: an in-depth tutorial on how to restore used kleenex (paper handkerchiefs) using only hydrogen peroxide, carbolic acid, jumper cables, an electron microscope and a particle collider -- so stop throwin' them away!!

There are ready-made battery holders on the market for €1-2. In this arrangement the batteries may leak or explode. In any case, the charge acquired is minimal, it will never be like that of a new battery.

I have batter rechargers. They seem to get the volts up but not actually be useful. They are supposed to work best if your just topping them off a bit.

Las baterías ( o pilas ) secas no se recargan ....yó lo hice con un transf y es cierto q vuelve a su carga normal .....hay q controlar el calor d la pila mientras se recarga ( para q no estalle ) .....el problema es q la carga aplicada no dura absolutamente nada ...o sea muy poco ....las pilas o baterías secas tienen un proceso d una pasta dura q almacena los electrones ...cuando estos pierden la energía, la recarga es inútil ...porq son secas ....carga ...pero no dura nada

Lo mas posible es que se hinchen o derrame el acido, aparte de quemarse con desprendimiento de vapores tóxicos

Do not do this! Years ago I tried reactivating a battery using this method. To be safe I enclosed the gear inside a metal cookie tin and then left it in my garage charging at about 100 mA. When I returned later my garage was full of black smoke! Fortunately no damage was caused except to my pride!

Time killer😊

DANGEROUS!!!!!

I do this all the time but they don't last quite as long the second time around but they are ok for radios etc.

yo lo he hecho h , con cuidado que No desmienten demasiado, Si es posible carcarlas. No dura demasiado la Carga pero " te puede salvar de una Emergencia o de un apuro si estas lejos de la ciudad y puedes tener una fuente de energia alternstuva. Gracias por tu trabajo y por compartir experiencias. Trata de hacerte tú mismo pilas de Sal y otras alternativas . Te salen gratis. ¡ Salud !

Which video camera do you use?

This is not a how to restore one trip batteries, this is flogging a dead horse. Getting an apparent immediate readable voltage does not mean a recharged battery. It wont have much if any ampere hours in recharged storage. Its slightly dangerous too, they may explode in your face. A one time battery works at the principle of sacrificing 2 different metals according to galvanic series (search and read) exposed to an acidic solution that corrodes the least valuable metal. Battery dies at the depletion/total corrosion of that lesser metal. But hey, I like your home made battery array. You could make some nice power packs for rechargeable batteries with those. Go shop some 18650 Li-ions or so and have some fun. Long range e-bike? Electric moped ? Solar panel power bank ? Lots of people throws away power tool batteries when they fail, usually its only a cell or two that has gone bad and there are usually many in each pack, each holding 3,6V as healthy. Both most battery power tools and most laptops uses 18650 Li-ions. There´s a good and free waste reuse supply.

People have been recharging "dry" batteries for over 100 years. Competently designed systems use a variable power supply with a (milli) ammeter in series to minimize the chance of excess current causing the batteries to overheat and burst. The best results have been mediocre with the recharged cells having but a small fraction of the amp-hour capacity of new ones.

It cant get usable capacity...only for a while, when it stuck for some energy angry devices it will be usable for seconds

Dah! They do sell rechargeable batteries for yes more money but can be safely Cha raged several times in a unit made especially for this.

I liked the understated background music....

Very interesting! What was the purpose of the baking soda?

We have a charger that can recharge ordinary batteries.(I bought it about 20 years ago and its called battery manager ultra) It trickle charges them. I have used it for years without problem. A battery charged with it will work a second time and run out more quickly. It can then recharge again and each time runs out faster. I think about 3 times is the limit. The better batteries do best with it. Very cheap batteries you only get one recharge and then they just wont . It shows a screen with how its doing, whether its viable and turns it off when its done. You cant do lithium or damaged batteries with it. Your idea seems similar but I suppose you havent got a safety measure so you must monitor it by eye and not leave it when charging.

I found it easier to buy a Bulk Pack of AA Batteries when I was in the DIY store. Can't be bothered with all that messing around to save pennies.

Besides this, it has got power again, but for how long? The capacity is most important

Which glues used?

“I know a way to do this in an even more complex way,” said the Snow Queen.😀

I just wanna know, how many hours this charging, once the batteries are charged, last ?

Eso es solo un cargador rústico,si la batería es recargable,,seguro se cargará,pero si son desechables,lo dudo

I FELL ASLEEP

The best part of this video is the camera.

Holy shit just go out and buy a pack of batteries for a $1.99... 🤡

Ive recharged regular batteries for decades now. Yes some batteries when recharged will burst and leak all over the enclosed charging box so i set the box upright so if that happens the acids will only leak on to the lower pad. Ive recharged several two or three times before discarding. Never had any of them explode like a bomb although that can be a possibility so the reason for the enclosed box as an additional safety. Last five years i only charge nickel-cadmium, lithium, metal-hydride types. Got lazy to clean the box when one of the older lead-acid batteries would leak.

When I was 12, I used to do that with a long string of battery's on the Home phone line in my room. 1966. Whenever I did that, the phone would not work. People would call and freak out and call 'Bell" I never told my mom why but my batteries were all good..

This method is the best one to get your house on fire ! It is very dangerous to try recharging a battery. Very dangerous...

Good tips

you can recharge discharged alkaline batteries once in a while if you charge with pulses. There is a risk of explosion because gases are formed inside the battery.

Super!

BRAVISSIMO

Putting then in a warm place (on a radiator or in the sun if you're in a hot country) works just as well.

If this method of saving old batteries is so good. Why does he have a tub full of old batteries? Why hasn't he recharged his original four-pack of batteries already?

Eh puesto baterías no recargable en un cargador. Pero solo lo eh dejado por unos 2 minutos. Sirven para un control remoto. Seguramente dejándolas más tiempo se recalentar a y explotaran

Yes but how long will they hold that charge compared to a new battery ? under a load ? My Guess is not long LOL

Complimenti!

Correctly

IT'S A CHEMICAL REACTION. WHEN IT FINISHES, NOTHING CAN RESTORE IT.

Juste une remarque : Vous contrôlez la qualité d'une pile avec un voltmètre numérique. Or pour s'assurer qu'une pile possède encore de l'énergie, son contrôle doit se faire en courant sur le calibre 1Ampère et si possible avec un ampèremètre à aiguille. Si l'aiguille dévie brusquement à fond, c'est que la pile a de l' énergie. Si l'aiguille se déplace sur le premier tiers du cadran, la pile peut aller au recyclage. De plus votre intervention est dangereuse.

OMG, jankiest construction ever but I had to keep watching. The methodology and time involved, and it is in a state of waiting to start falling apart right from the start.

Use a battery charger, for any battery type. But, alternate dry cell batteries with the nondry cells to act as a capacitor in the circuit. The dry cell batteries will prevent the nondry cells from overheating and melting the plastic insulation. You can reuse any type of batteries about 8 times before oxidizing gases or deteriorating conditions sufficiently reduce quality.

Soy de cuba,si se pudiera comentar el vídeo ebacuaria muchas dudas.

il existe des chargeurs specifiques pour pile alcaline ou saline si la pile affiche encore plus de 1.2 v. on peut alors les recherger une dizaine de fois maximum

That can not be pluged into the mains 220V here in UK?

Muy buena la narración 😂😂😂

Nowe baterie ładowałeś? Naładuj te stare, które miały na początku filmu 0,9V 😁

Proof that 'a little knowledge is a denderous thing' Don't do this, there is no current regulation or voltage stabilisation.

A voltage of 1.7V after "recharging" doens't tell anything about the capacity. To put it simple:There are rechargeable batteries and non-rechargeable battries. Never try to recharge a normal battery. It's a waste of money and time. Besides, it's dangerous, as they can explode

Yes, this can work; but it can be dangerous -- and the "recharged" batteries won't last. Either buy some new batteries or buy rechargeable batteries and a decent charger.

Este tema de recargar baterias no recargables, es posible, pero no siempre funciona, depende del desgaste interno de los materiales que producen electricidad mediante una reaccion quimica al interactuar. Es decir si estos materiales han perdido sus propiedades, por mucha carga que se intente, las baterias seran incapaces de almacenar la energia y aunque midan e voltaje correcto son incapaces de retener la carga. por otro lado las baterias no recargables al no estar diseñadas para ser recargadas, son propensas a explotar.

I have done this for years and I am going to give you certain facts. 1- Never recharge them more than once 2- Never recharge them for more than 1:30 hours 3- Always recharge in a safe area and away from flammable objects 4- Never recharge if you are going to leave them unsupervised 5- You can use a rechargeable battery charger 6- Once recharged, the useful life of the battery is 50% of its previous life time 7- It is a lifesaver when we do not have the possibility to go shopping or when we do not have time to go 8- The first test should be in a patio or a safe area of the house, since they were not designed to be recharged, some of poor quality could deteriorate easily, heat up to the extreme, release some liquid or even catch fire. 9- Better buy rechargeable batteries, I have been recharging my batteries for more than 5 years and they continue to work perfectly and I have saved a fortune 10- Free Palestine!

Se quer recarregar há pilhas recarregáveis e seu carregador próprio

You’re Genius, next time I’ll see you on the sandpit.

"Wow, what an eye-opening video! I never knew you could actually revive old batteries like this. The step-by-step guide was clear and easy to follow. Thank you for sharing this valuable knowledge with us!"

Try は「Watch」ではなく、Clock」ではないでしょうか？！！！。

Si estas baterías se las expone al sol durante un día con su positivo apuntando a mismo se carga

If they are not rechargeable batteries, they cannot be charged in any way.

The method used to check multiple batteries is to line them up with the polarity to your right, (if you are left handed) and then start at the battery furthest away and work towards yourself, as you run across an unsatisfactory battery, you simply put enough squeeze on it to pull it out an flip it off to your left side, usually leaving a void so you don't forget where you left off, Now I still owe you nine (9) minutes of waisted time, Or is that time owed back to me ?

Nice sharing👍

PERO PARA HACER ESO DEBEN SER PILAS RECARGABLES, SINO EXPLOTAN. 🙏🙏

No sabía que no se pudieran recargar varias veces, buena idea.

Für sehr kurze Zeit ist die Spannung wieder da, aber sie hält längst nicht so lange vor wie bei neuen Batterien. Ich gehe lieber zu Lidl und kaufe neue Batterien.

Honestly, why bother? Stuffing a mushroom would be quicker, easier, and more gratifying.

This is really easy to test if he is right or wrong. 1 Take a new battery and test how long it takes to get empty with a device. 2. Take his "charged" battery and see the difference in working time. I would guess that the charged battery gonna last about 30% of the time a new battery lasts. So it might be a "temporary" solution but not a miracle one. I would rather use lithium batteries since they are cheap enough, have more power, and are truly rechargeable. Or just use a Ni--Mh rechargeable battery like Eneloops or others since they are cheap enough too.

Trying to charge non-chargable batteries this way without currentcontrol or anything can lead to internal gass-buildup and explosion, don't take the risk its not worth it..

This video is a game-changer! I never knew you could revive old batteries so easily. Thanks for the step-by-step guide, it's going to save me a ton of money. Can't wait to try it out myself

Absurdo !! Isso não funciona e é muito perigoso !! Use pilhas recarregáveis.

Can you charge it even if it's not an alkaline battery Ally sells an alkaline battery charging machine You're working so hard to sell that stuff

Es una bomba de tiempo....!!!!!!

These batteries are not checked properly (on short circuit amps). The voltage itself is not telling much about battery internal resistance (the real issue with used batteries). Plus, the new alkaline AA battery is expected to give (short time) 6A and above. No non-rechargeable battery can be restored to that current. Even rechargeable batteries charging time cannot be less than 4 hours in the high speed charger (which itself destroys rechargeable batteries).

Zuerst einmal: Du könntest von vornherein aufladbare Batterien (=Akkus) und sichere Ladegeräte verwenden bzw. kaufen. Es gibt auch schon gute und sichere AAA und AA 1,5 V LiIon-Akkus mit USB C-Anschluss. Ich glaub, das wäre der sicherere und auf lange Sicht der bessere und billigere Weg. Und du müßtest nicht so lange amateurhaft herumbasteln! At first: You could also generaly use or buy rechargeable batteries and safe charging devices. there are also some good and safe AAA and AA 1,5 V LiIon batteries chargable with normal USB C cables and USB power supply. I think that would be cheaper and better in the long run. and safer. And you can spare these "simple" makeshift solutions ...

When you use 3 batteries folder, the time of this video might be eliminated about 10 minutes.

Ese invento que estás haciendo ahí compañeros extremadamente peligroso

Never do this guys! Non-rechargeable batteries may explode!

you are not going to restore any kind of battery back to like new once its used up , period

This is wasted time I will never get back...

This idea is creative but I would not try recharging "non rechargeable" batteries. I tried that with a certified battery charger and a few of them were expanding like they were ready to explode and cause a major fire and personal injury. This was many years ago but never tried that again. I always use certified battery chargers that only can charge "rechargeable batteries. That's why they are manufactured for those that need to reuse batteries. I do give you full credit for trying to invent a battery charger for "regular" battery types. That would be incredible if it succeeds and gets patented. Update, I saw the full video and you did succeed. Looks like this method may work, but did you use heavy duty batteries or did you use alkaline batteries. I tried with Duracell Alkaline and those were the ones that expanded severely, even on one attempted recharge.

I only have chicken batteries so they will lay more eggs if recharged or maybe not.

High-explosive ...

DO NOT DO THIS. Buy the rechargeable batteries if you don't like tossing batteries away." Many batteries have a notice warning you not to recharge them. I have rechargeable batteries that are 3 years old, I have charged them at least 50 times and they still work.

Ich kann Ihnen nur raten machen sie das auf keinen Fall Zuhause nach was hier im Video gezeigt wird! Ist ja erschreckend wie Elektronik hier dargestellt wird.

Cheaper to go and buy batteries.

deja compro las pilas nuevas ,

PASTIZO'N !

While re-charging this could explode.... and also the charge will not last for long... Waste of time... Man!

so dangerous these batteries are not the rechargeable type you risk them blowing apart.

BEFORE I'D GO THROUGH ALL THE PAIN AND SUFFERING OF DOING ALL OF THAT I'D JUST BUY NEW BATTERIES.
