You are 100% correct. Dad showed my how to do this decades ago & I used dumb charges until I had a liquid accident & shorted out my old dumb charger. Bit the bullet & bought a MaximalPower charger from Amazon for around $30 which is able to recharge alkaline batteries. I never accidentally overheat a battery now. Even better is I have had much better luck charging batteries that have voltage reduced to 0.5 volts although they seldom will exceed 1 volt later but work well in low demand applications like a remote control for a TV. You are also correct that Rayovac batteries have the best case. Duracell cheapened it case & will leak from not only a seal but from the side. Every ready makes a good case but seals are prone to leak. Have been using the MaximalPower charger for 6 months & enjoy the ease of use since it has never overheated a battery & I can leave them in overnight since it goes into a very low trickle mode & displays an idiot green light.
Alkaline batteries are insanely rechargeable, not so much for carbon zinc but they can be recharged with the proper precautions. When the rechargeable in those solar stake lights for your yard eventually die I just stick in some alkaline and they work for months of charge cycles before dying. An Xbox or Wii controller will also greatly benefit from recharging alkaline batteries, just make sure you cycle the charge on and off so they do not explode.
About 75% of the time I'm looking up something practical, thrifty, or even just a new "kick***, interesting!" thing to try, I stumble across your vids. So...thank you, once again! Have a great day. :-)
I did that for years with an old Radio Shack charger, the type that can take 8 various sizes batteries at the time. The only difference is the timing set-up. 1 Hr ON, 1 Hr OFF for about 10 hours.. and since the charger is in the garage, evething stays cool. So far I never had leakage or overheating and it realy streches the batteries' life..
I just charge mine in a charger that's made for the energizer rechargeable batteries. It needs two to charge so What I do is place in one Alkaline battery and one Energizer rechargeable battery It will charge both and not show an error by flashing red. But if you place only two Alkaline batteries it will flash Red to show and error. Just place in one energizer rechargeable battery and one none rechargeable Alkaline battery. That's how I do mine and it works. It even charges the cheap alkaline batteries easier than the name brand but will recharge both
I have also used these type chargers to charge my Alkaline batteries. Basically the same way you do. I also have one of those alkaline battery chargers, but they are really terrible at charging dead batteries. So I pretty much have to charge them up like this anyway. This really works for those who want to try it. I have been charging batteries this way for years now.
Thank you for the informative video! So the main issue with recharging "non-rechargable" batteries is the cycle the charging process on and off so that they do not overheat and become damaged, right?
Worked like a charm. Had a bag of batteries that I was going to take to batteries plus to get rid of. Tried recharging and now a lot of them are fully topped off and ready to go again. Thanks so much.
The classic way of charging non-rechargeable batteries is to charge them with AC. With 2 resistors and 1 diode, you charge them at the positive pulse and discharge them approx 10% each negative pulse. For an AA battery that would be about 100mA at the positive pulse and 10mA at the negative. You will generally get a much better result compared to charging them with DC. The drawback is that you have to buy the components and build it yourself, or modify an existing old charger.
And this method will likely work even better if you AC charge them for 5 minutes and rest them for 15 minutes, and repeat the charge & rest cycling until they are finished.
i go through about 45 AAs a month filming my videos and have been pondering charging them. i think i may just connect them to my universal power supply at limited amps with like 100ma of current and have it top out at 1.6v do you know if the alkaline batteries will stop at 1.6v? like for instance lithium ion batteries will just keep raising in voltage till they are like 140% charged then short out. unlike lead acid batteries that settle down to 2.2v as long as you don't overcharge them. most of the time LiPo cells will short out after 4.3v but i accidently got a pack of 4 cells to 4.7v and none of them blew. i was handling them like unexploded dynamite while i was connecting a motor to discharge them haha thanks for this video!
Rinoa Super-Genius I've had some of them up to 1.9 and know that's a little to much. But they seam to handle it just fine. The biggest thing with these is them getting overheated and by that I mean even slightly warm. If they do get warm the tend to leak. I would charge them super slow at around 50 mah.
I would think the same rule would apply by charging and hour and letting it rest for two. So far so good on the alkaline batteries. No need to take them in to recycle when you can just charge them back up again.
Don't for Gods sake try and charge Lithium batteries like this. They will explode. The old chargers are not intelligent and will not limit the current. ONLY use an intelligent Lithium charger for Lithium batteries!
Just stick them on the old RayOVac rechargeable alkaline charger that says 3-in-1... works great. The one before that works great too, just wrap the top in some foil on the positive (point side)
65ford, finally trying it out today. I got the same Centech multimeter you are using the video. Hard to figure that thing out! Luckily I could see on the video where you had the dial on the multimeter, on "20" in the DCV section, but don't understand it. Does the charger output volts and amperes matter? My charger says 2.4VDC output at 140mA.
It will give you a good idea of how long a battery needs to charge. A standard Alkaline is somewhere in the neighborhood of 1500-2500mA. so at 140mA charbing rate it would take 10-15 hours to charge a battery.
sixtyfiveford well i put in two AA batteries that were 0.92v, charged them overnight on timer set 1 hour on, 2 hours off. unfortunately both of them dead and one of them leaked. no loss, i had given them up for dead anyway. I guess i should have checked on them sooner to see how they were doing. Does that ever happen to you?
Yes. If they are really old or have been dead for a long time they are less likely to take a good charge. Dead batteries that are around 1.2 or more take a charge better than others.
that battery charger... it is so vintage. Well, relatively. I had one as a kid except mine was the larger one. I miss that thing. I found one on Ebay and almost bought it. However, I just buy rechargables now and run my xbox controllerso ff them.
Great info!! I recently got 20 6v lantern batteries for free because they were close to their sell by/use by date and I heard if you rip them open they have 8 D-cells inside...YEP , so I've been getting good use out of them , and I have about 8 tired 1.5v D-cells sitting on the bench that I'm heading downstairs right now to try the timer-charging method on.......thanks!!!

+Bruce Kersman Lithium are dangerous cells and are deemed dead once they get to the point where they no longer charge. Forcing charge into them can cause them to explode into a ball of flames.
sixtyfiveford Only if you don't know how! If it looks dead use a charge of 10 miliamps in 90% of all cases it will start to load again. After it has received enough to reach 2.8 volts you can use a normal lithium charger again.
I was thinking about this vid. I "jumped" a battery pack on an old streamlight that wouldn't charge with an 18V drill battery to get the temporary charge up to a point where it would register on the charger. Just touch the dead battery ends with wires hooked up to a battery about 2-3X the power. Would that work for alkaline batteries that are too low to register on the charger? I ask because I haven't tried it yet. Maybe a way to revive even the deadest alkalines? There are other vids on youtube on how to do this process of "jumping" the dead batteries for those interested. It mainly deals with drill batteries but a battery is a battery. Again, awesome vids!
I haven't tried it on Alkaline but I have done it on Nicads. I have tested and retested jumping batteries on numerous occasions and every time it is only a small band aid. It gives the cell a superficial surface charge and then you charge it but it never holds any real capacityy. The cell always seems to self discharge extremely fast as well.
You said "...if there are over 1.5 volts you know 1.6 or so then i know they fully charged." and I say : NO you dont! They can be near empty with only few mAh "juce" left and with that voltage, but with a slightly load on it, voltage will drop insanely fast, because they lack of charge. I dont say you cant recharge alkaline battery, Im just saying you can charge it with about XX % of its original capacity and that voltage isn't measurament if its something fully charged or not. (original capacity of Alkaline batteries is around 500-1000 mAh for AAA and up to 2000 for AA) Years back then there was rechargeable alkaline batteries, almost a same like todays alkaline "non rechargeable" only difference was some aditives in cathode and some catalyst to recombine and neutralize hydrogen that forms by Zn compound while battery is charging.
You have what I call "Real Knowledge", euronymous85. Earlier TH-cam shows batteries that are dead, then charges them for 5 minutes and flashlight works. Calls the batteries charged. hahaha.
hello! i just found your video , so i hope you see my comment. i recently bought a new camera and it powers up on 4 alkaline batteries , the thing is - it eats the batteries like crazy , i used a few different types of alkaline batteries and they have a short life. like i recharge them max 4 times and they die , they can't be racharged or used anymore. so , i thought its just shitty batteries. i found today (after a whole adventure of searching) energizer maximum + power boost AA batteries (4 batteries per a package) and they weren't quiet cheap but not too expensive either , i was googling them and aparently they are the best batteries for cameras on the market. my question is do you have any advice for me , can i recharge them? are they gonna explode? i hava a basic -Sony Cyber Energy- battery reacharger and it worked fine until now. im new to this whole battery stuff so im really curious about this specific type (energizer maximum + power boost AA batteries). so i would be really thankful if you responded! i liked this video and suscribed and im really happy you made this channel bcs its really hard to find battery info on the internet. god bless you
I've never attempted to recharge the Energizer Max + Power Boost. If it eats batteries extremely rapidly have you considered actual rechargeable batteries? Generally an Alkaline will have an initial higher capacity than rechargeable Nimh batteries but alkaline will be lower after the first and remaining recharges.
Good video but entirely a complicated process and to much wasted energy. Would be less of a hassle to buy a new battery charger and rechargeable batteries only. You would be surprised how inexpensive a Charger on sale cost and you would be even more surprised at the cost of rechargeable batteries for-sale at your local flea market, 1/2 price. Oh and by the way I really like the coke machine ... awesome!
Most basic chargers are based around 1.4 X battery capacity / time, so they put 140% in for 100% out (if you use them straight away). Interesting to see what you get out of yours for the input :-)
I recomend battery testers good fast way 2 cheak charge or single batterys. And somthing ive found out if a remote of somthing dies most times all the batterys arnt ded maby only 1 is then it dont git the volts it needs then it ses its ded cheak both charge the ded 1
ALL batteries are made at 1.5v or combinations of the same eg. 4X1.5 = 6v etc etc 6x 1.5 9v etc etc so there is not a 6v battery as such but is made up of 4 1.5v. Just a useless piece of info......
I meant to add the following info Note: Rechargeable AA, AAA, C and D size batteries are 1.2 Volts instead of their 1.5 Volt non-rechargeable equivalents. Rechargeable "9 Volt" batteries are 8.2 Volts unless otherwise stated.
Technically, the 1.5V "batteries" are really cells - carbon-zinc dry cells, I believe. (Other electrolytic cells have different voltages.) The 6V battery really *is* a battery . . of 4 cells, each 1.5V, or 4N of them, in 4 parallel groups of N, the groups connected in series. "Battery" means a group of cells, connected either in parallel, in series, or both. It's just that it commonly gets used for a single cell, in everyday speech. And yes, the rechargeable cells are lower voltage than the non-rechargeables. Which means that sometimes, they don't do the job as replacements.
EBL® 920D LCD Rapid Advanced Intelligent Smart Individual Cell Battery Charger/Discharger for AA AAA Ni-MH Ni-CD Rechargeable Batteries (Black) (Electronics) Fine for slowish 4 hour plus charge of rechargeable batteries, this is not a bad thing batteries do not get hot and have a longer life . Beware alkaline batteries. I checked carefully that some alkalines were not overheating on charge for 2 hours. Touching the batteries to check the heat one battery/, even though not hot, fizzled. It had started leaking caustic fluid through the bottom of the battery past the plastic sheath. All the charged batteries had an open circuit voltage of 1.7 volts. I wiped clean the leaking battery and left all the batteries for a day on a piece of hardboard. Even after cooling the leaking battery continued to leak caustic fluid that etched through the surface of the hardboard. Clearly this battery could damage any equipment it was put in. If you want to try recharging alkaline batteries use the charger upside down so leaked caustic fluid doesn't rot the circuit board beneath the terminals. Leave any charged batteries for a day or two on an old piece of hardboard.I have read elsewhere that putting a timer switch set to,1 hour on two hours off for a total of 15 hours can help with good in date alkalines that measure more than 1.2 volts. So yes in 15 hours you can recharge an in date alkaline battery that is not too discharged and it may not leak caustic fluid. Other possibilities are: leakage occurs while charging corroding the circuit board of the charger, leakage occurs later corroding terminals or circuit boards of equipment. Apparently you can charge alkaline batteries up to 10 times so 150 hours of charging 20 days looking at a piece of hardboard for caustic leaks and no guarantee your equipment wont be corroded - is it worth it ?
WARNING. My akaline charger works fine, but charge em too many times and they leak, the damage this causes it`s just not worth it. nearly ruined my Maglite and my Black & and Decker screwdriver, Kodak.Panasonic and Sony are all good from the pound shops. also i have my doubts on some Duracell and Energiser batteries from ebay.
I hear you. All it takes is one leak in a $400.00 digital camera and all of this "battery economics" is for nothing. I use only Sanyo (now panasonic I think) eneloop NIMH batteries, in a "smart" ("Lacrosse technologies") charger. The eneloops are absolutely the best. I'm an insurance adjuster, so, I use a digital camera every day and I have to depend on my batteries to work every time. The eneloops are amazing and are worth every penny.
Ive used uniross rechargeable for years and find them great, i agree about battery economics one leak and it`s all over, my AOR scanner has had one set of Uniross 2400mah in it for 10yrs although it doesn`t get used an awfull lot they amaze me. ive just bought a Nitcore D2 charger seems quite good. it charges Li Ion and NIMH .

sixtyfiveford Only if you don't know how! If it looks dead use a charge of 10 miliamps in 90% of all cases it will start to load again. After it has received enough to reach 2.8 volts you can use a normal lithium charger again.
just want to say like your vids, you are a great hacker and teacher, keep it up!
Thanks for the compliment and feedback.
i recharge my alkaline and heavy duty batteries with imax b6 charger by setting - ni-mh manual charge 0.1A
Like others have said quick and right to the point might have to try this.
Thanks.
@7:08 i got the same T shirt ! Great vid ,this will save me some $.
Cougar rides! Thanks, I'm glad you like the video.
is it really work 100 % ?
80% is a realistic capacity.
I was thinking about this vid. I "jumped" a battery pack on an old streamlight that wouldn't charge with an 18V drill battery to get the temporary charge up to a point where it would register on the charger. Just touch the dead battery ends with wires hooked up to a battery about 2-3X the power. Would that work for alkaline batteries that are too low to register on the charger? I ask because I haven't tried it yet. Maybe a way to revive even the deadest alkalines? There are other vids on youtube on how to do this process of "jumping" the dead batteries for those interested. It mainly deals with drill batteries but a battery is a battery.
Again, awesome vids!
I haven't tried it on Alkaline but I have done it on Nicads. I have tested and retested jumping batteries on numerous occasions and every time it is only a small band aid. It gives the cell a superficial surface charge and then you charge it but it never holds any real capacityy. The cell always seems to self discharge extremely fast as well.
very informative thanks,,, helped me a lot on how to use multimeter
+Brenda C Thanks, I'm glad it helped.
awesome, thanks, I'll share this around. great informative video, going to help a lot with Xbox controller batteries!
Good idea! Thanks for sharing.
Thanks.
You said "...if there are over 1.5 volts you know 1.6 or so then i know they fully charged." and I say : NO you dont! They can be near empty with only few mAh "juce" left and with that voltage, but with a slightly load on it, voltage will drop insanely fast, because they lack of charge. I dont say you cant recharge alkaline battery, Im just saying you can charge it with about XX % of its original capacity and that voltage isn't measurament if its something fully charged or not. (original capacity of Alkaline batteries is around 500-1000 mAh for AAA and up to 2000 for AA)
Years back then there was rechargeable alkaline batteries, almost a same like todays alkaline "non rechargeable" only difference was some aditives in cathode and some catalyst to recombine and neutralize hydrogen that forms by Zn compound while battery is charging.
You have what I call "Real Knowledge", euronymous85. Earlier TH-cam shows batteries that are dead, then charges them for 5 minutes and flashlight works. Calls the batteries charged. hahaha.
wow, this is a good idea, i should try dis with my junk ones, if they explode I'm not gunna care to much. but what a smart idea! :)
I've purposely tried to overcharge and the worst they do is leak.
Only recharge regular batteries only 15 times after that they wont recharge.
Duracell, Energizer and Rayovak.
Its "Rayovac."
hello!
i just found your video , so i hope you see my comment.
i recently bought a new camera and it powers up on 4 alkaline batteries , the thing is - it eats the batteries like crazy , i used a few different types of alkaline batteries and they have a short life. like i recharge them max 4 times and they die , they can't be racharged or used anymore.
so , i thought its just shitty batteries. i found today (after a whole adventure of searching) energizer maximum + power boost AA batteries (4 batteries per a package) and they weren't quiet cheap but not too expensive either , i was googling them and aparently they are the best batteries for cameras on the market. my question is do you have any advice for me , can i recharge them? are they gonna explode? i hava a basic -Sony Cyber Energy- battery reacharger and it worked fine until now. im new to this whole battery stuff so im really curious about this specific type (energizer maximum + power boost AA batteries). so i would be really thankful if you responded! i liked this video and suscribed and im really happy you made this channel bcs its really hard to find battery info on the internet. god bless you
I've never attempted to recharge the Energizer Max + Power Boost. If it eats batteries extremely rapidly have you considered actual rechargeable batteries? Generally an Alkaline will have an initial higher capacity than rechargeable Nimh batteries but alkaline will be lower after the first and remaining recharges.
Good video but entirely a complicated process and to much wasted energy. Would be less of a hassle to buy a new battery charger and rechargeable batteries only.
You would be surprised how inexpensive a Charger on sale cost and you would be even more surprised at the cost of rechargeable batteries for-sale at your local flea market, 1/2 price.
Oh and by the way I really like the coke machine ... awesome!
+dolphinsc1 Yeah, this is more of a "it's possible" scenario.
+sixtyfiveford
Good video and very interesting.
+dolphinsc1 I don't really see how complicated this is. But then again to each his own.
+Yo Drop
Right.
It's also better for the environment if you can get several uses from what's normally a single use product
Most basic chargers are based around 1.4 X battery capacity / time, so they put 140% in for 100% out (if you use them straight away).
Interesting to see what you get out of yours for the input :-)
The battery charger never has the correct voltage hmmmm.
I recomend battery testers good fast way 2 cheak charge or single batterys. And somthing ive found out if a remote of somthing dies most times all the batterys arnt ded maby only 1 is then it dont git the volts it needs then it ses its ded cheak both charge the ded 1
I thought they could explode.....
I did it but they don't hold a charge, so it's useless and a waste of time.
Just pulled out a set of AA that held charge in my computer mouse for over a year.
@@sixtyfiveford -That tells me nothing. A dead discarded battery will last months in a computer mouse.
2 hours to cool down sounds extreme.
It's not just cool down, it gives the battery a chance to equalize the voltage and absorb it.
@@sixtyfiveford -- great answer, and have you experimented between 90min, 120min, 180min, and 240min?
ALL batteries are made at 1.5v or combinations of the same eg. 4X1.5 = 6v etc etc 6x 1.5 9v etc etc so there is not a 6v battery as such but is made up of 4 1.5v. Just a useless piece of info......
I meant to add the following info
Note: Rechargeable AA, AAA, C and D size batteries are 1.2 Volts instead of their 1.5 Volt non-rechargeable equivalents. Rechargeable "9 Volt" batteries are 8.2 Volts unless otherwise stated.
Technically, the 1.5V "batteries" are really cells - carbon-zinc dry cells, I believe. (Other electrolytic cells have different voltages.)
The 6V battery really *is* a battery . . of 4 cells, each 1.5V, or 4N of them, in 4 parallel groups of N, the groups connected in series.
"Battery" means a group of cells, connected either in parallel, in series, or both. It's just that it commonly gets used for a single cell, in everyday speech.
And yes, the rechargeable cells are lower voltage than the non-rechargeables. Which means that sometimes, they don't do the job as replacements.
Love the coke machine
+sixtyfiveford I get hooked watching your stuff then I don't get my stuff done. Keep it up ;-{)
You're comment is great. Thanks for watching.

Fine for slowish 4 hour plus charge of rechargeable batteries, this is not a bad thing batteries do not get hot and have a longer life . Beware alkaline batteries. I checked carefully that some alkalines were not overheating on charge for 2 hours. Touching the batteries to check the heat one battery/, even though not hot, fizzled. It had started leaking caustic fluid through the bottom of the battery past the plastic sheath. All the charged batteries had an open circuit voltage of 1.7 volts. I wiped clean the leaking battery and left all the batteries for a day on a piece of hardboard. Even after cooling the leaking battery continued to leak caustic fluid that etched through the surface of the hardboard. Clearly this battery could damage any equipment it was put in.
If you want to try recharging alkaline batteries use the charger upside down so leaked caustic fluid doesn't rot the circuit board beneath the terminals. Leave any charged batteries for a day or two on an old piece of hardboard.I have read elsewhere that putting a timer switch set to,1 hour on two hours off for a total of 15 hours can help with good in date alkalines that measure more than 1.2 volts.
So yes in 15 hours you can recharge an in date alkaline battery that is not too discharged and it may not leak caustic fluid. Other possibilities are: leakage occurs while charging corroding the circuit board of the charger, leakage occurs later corroding terminals or circuit boards of equipment. Apparently you can charge alkaline batteries up to 10 times so 150 hours of charging 20 days looking at a piece of hardboard for caustic leaks and no guarantee your equipment wont be corroded - is it worth it ?
That's great!
Thanks.
Another good one...thx.
Thanks Man.
WARNING. My akaline charger works fine, but charge em too many times and they leak, the damage this causes it`s just not worth it. nearly ruined my Maglite and my Black & and Decker screwdriver, Kodak.Panasonic and Sony are all good from the pound shops. also i have my doubts on some Duracell and Energiser batteries from ebay.
I hear you. All it takes is one leak in a $400.00 digital camera and all of this "battery economics" is for nothing. I use only Sanyo (now panasonic I think) eneloop NIMH batteries, in a "smart" ("Lacrosse technologies") charger. The eneloops are absolutely the best. I'm an insurance adjuster, so, I use a digital camera every day and I have to depend on my batteries to work every time. The eneloops are amazing and are worth every penny.
Ive used uniross rechargeable for years and find them great, i agree about battery economics one leak and it`s all over, my AOR scanner has had one set of Uniross 2400mah in it for 10yrs although it doesn`t get used an awfull lot they amaze me. ive just bought a Nitcore D2 charger seems quite good. it charges Li Ion and NIMH .
put your duraleak batteries in a diaper as they always leak
Sometimes no good
So many boring talkies that show how.
Boring
Go BarBQue a goat or something.
No thanks, I don't want my batteries exploding
