Probably you had not only to replace the zinc dust, but also recharge the battery before you seal it hermetically, because not only zinc is consumed during discharge process, but also manganese dioxide is reduced to lower oxidation states (+2 and +3 from + 4 and that will explain why you have lower voltage.

***** Actually you don't need to refill MnO2 into battery. What is left in battery when MnO2 is partially consumed is a solid state solution of MnOOH (Mn+3) in the MnO2 lattice (Mn+4). More importantly these ions are quite mobile in lattice and you can replace/oxidize easily Mn+3 to Mn+4 (unless most of +4 is already lost) just applying external voltage to battery - just charge battery! I'll suggest to use a current source with few mA of current in the course of many days, the slower the better.

the thing with dictionaries is that they give many examples ... but not all definitions are applicable. Yes, "charge" can mean to fill something that is empty...but in this case, the battery was full of the material, but it had lost its ability to produce electricity, so the actual contents had to be removed before he could add the new material. To DIScharge a battery is to use it as a power source until it is "dead"...but the contents are still inside it, just not chemically reacting to produce electricity. If you were to recharge the battery you would either connect the battery to a current to replenish its electrical reserves, or you would disassemble the battery, remove the contents and replace the material altogether, which is a rebuild or re-manufacture...or perhaps reload.

20 years ago I purchased a Buddy L charger, it charges both NiCad and Alkaline batteries. It was touted to charge lesser branded cylindrical batteries 2-3 times, and better branded batteries 10-12 times. It has revived old batteries numerous times and still works to this day albeit one of the spring mechanism hold downs broke. In conjunction to your method shown here I would think you could get years of battery power with minimal cash outlay.

I worked at Rayovac for 27 years, I may have had a part of making those batterys. The zink we used was a coarse ground zink. There is only one Rayovac plant in the US.

When you went to measure the initial dead voltage I saw the negative symbol pop up. It would not surprise me to find that one (or both?) of the old corroded batteries had gone into voltage reversal. 1.273V is not too bad for a DIY alkaline battery!

It is certainly possible to recharge alkaline cells. There have been commercially-available alkaline chargers around for a long time, and the British manufacturer Fidelity made a series of radios and cassette recorders with built-in alkaline trickle chargers in the 1980s.

I just want to say, although they say do not charge, I've used regular AA/AAA battery chargers and although it doesn't work perfectly, it does work. And I've never had a battery explode or leak or anything like that. There are even battery chargers designed to recharge alkaline batteries.

I would guess that your choice of paper was the culprit in the voltage loss. But still, this was great!!!

Interesting video, not what I expected. You can actually charge alkaline batteries with electricity just like other rechargeables. I used to do this about 20 years ago before lithium ion was so cheap. They have to be charged at a very low current - like 25ma or so. You can get them to near new performance for a handful of cycles. The biggest problem is it tends to make them much, much more likely to leak inside your device.

Your video here reminds me of when I was cutting open old big batteries like this and harvesting the Manganese oxides and used them in thermite instead of iron oxide. Lots of fun except when one of the batteries cut my thumb. It would be cool if you did a video series for harvesting chemical supplies from everyday items.

You are measuring the potential difference between zinc atoms and manganese atoms arranged in parallel. You possibly diluted the voltage somewhat by adding the electrolyte, which lowered the resistance. Or it could just be that is the potential difference. You will only ever get 1.2 to 1.5v between two metals because the molecules are arranged randomly ie in parallel. In order to increase the voltage you would need to align the molecules in series, in a similar way that permanent magnets are made. You could also experiment with the strength of the electrolyte solution and see how how/if it affects the potential difference. Cheers, Matt. :-)

You can use pretty much any two metals with dissimilar sized atoms by the way, Zinc/manganese, Silver/iron, Zinc/copper, lead/coppper and you will always get a similar result. To have a battery that is continuosly charged by the universe (and never needs charging) you need bonded pairs of dissimilar sized atoms aligned in series... all the little 1.2v soon add up and then you will have lightning (aligned H2O molecules). That is also how lighting clouds (aligned H2O particles) continuously recharge after each bolt of lightning. Nature aligns the H2O molecules as a phenomenon and when the particles are no longer in alignment the storm dissipates. You can find bonded pairs of atoms which is the sludge at the bottom of used lead/acid car batteries. The atoms leave the battery elements and form bonded pairs during the eletrolysis process. When all the atoms that can leave the surface of the elements, have left the surface, the battery is considered spent. But they can be recycled by cleaning out the sludge and re-etching the surface of the elements. Cheers x2.

I used to recharge AA alkaline batteries for a little radio. I would do them by hand quickly. I am trying to remember the exact dc volt transformer I used but the way I did it was only to see if I could. I would hold the terminals on either end of the battery and count to 4 (at my speed that was what worked most of the time) I held them in a rag but kept one finger on the battery (you can feel it start to heat up). I would stop and let the battery cool a few minutes. I would do others while the first was cooling. Batteries would work for 4 or 5 hours then do it again. I was a kid and I was always doing things that people said you can't do. (Yes I did get zinc paste squirting out the end sometimes... it was now a throw away----recycle)
