That is pretty common. The silliest thing you can do is to put all type of sulfates into batteries in the hope of resolving a problem. Urban legends will never ever die. Pencil lead can contain some strange substances in addition to carbon (battery reconditioning equipment). There are a lot of carbon powder makers. Automobile tires have to do with 50% carbon.
Does not cost an arm and a leg. Afdhal- I get cadmium from utilized NiCd cells-aaa or aa sizes- such as found in solar garden lights- after a couple of years they are tossed out as NiCd is worn out- just cut around leading crimp with hacksaw, unravel s/s case with cutter, withdraw contents- external foil is cadmium, inner foil is nickel, & some strong electrolyte & seperator- all wound in spiral pattern.
To obtain Cadmium Sulphate, boil up some electrolyte- drop cadmium in- will bubble up & provide off harmful fumes- do outside -do not breathe vapours!!! When cadmium is completely dissolved( & sometimes the electrolyte cadmium mix is a beautiful green, depending on quality of cadmium from cell maker!)- task done! Got ta say- the mix I have included to batt cells does not appear to help! In fact- I got ta say the ONLY thing I used that worked was INOX MX2( in 1 batt so far- I will get some more MX2 &try; & shot; in other batts to validate yes or no! Apart from that, the other thing is that the batt itself must be just gently sulfated).
Still it is proficient at recognizing o/c cell/s in batt- pulses go up greater with degree of o/c! have seen 1250 volts! Cut open, & disintegrated pos grid! in 1 cell-others almost so!. battery recondition. Bevan - I would recommend refining the cadmium by making the cadmium you recuperated from the NiCds the positive in an electroplating cell.
Use a tin wire or solder wire negative. Power source can be 12V battery. Place 220 ohm series resistor. The cadmium that gets plated onto the unfavorable will be dendritic and pure. The real voltage across the electroplating cell will be under 0. battery reconditioning com. 5V. The green you describe would be nickel contamination.
Bevan - That's innovative! Why didn't I consider that prior to? I will try it. John - You're one wise gentleman, thanks for the info. Bevan - I believe I may have at long last managed to find out what cadmium sulfate does. It certainly electroplates out onto the negative grid metal when the battery is intentionally pressed into regulated overcharge.
This assists the lead sulfate nearest the grids to end up being active again and to be transformed into lead and sulfate ions. Duplicated charging, releasing spreads the conductive environment slowly and progressively into the bulk of the lead sulfate. The procedure seems to have a limitation. how to recondition a wore out battery. It would appear the trick to accomplishing 100% desulfation is to figure out how to get conduction to spread out into 100% of the sulfate.
Including progressively more simply produces dendrites and causes shorts. The descriptions offered by desulation merchants that insoluble sulfation undoubtedly coats the plates when batteries are used and that their treatment strips it away is pure dream. The sulfate remains right where it is. It is transformed. While both favorable and unfavorable plates can become sulfated, the favorable sulfation merely reverses when the battery is charged.
John - If I comprehend you properly, did you indicated all the cadmium does is electroplating itself on the unfavorable grid?If so, wouldn't simply copper is great enough? Afdhal- it is simply John's theory- however i would say cadmium does not simply plate itself- requirements driving- so does copper- BUT copper is a non laster in H2SO4! As are most metals! Lead lasts longer than most! Afdhal - No, copper and copper sulfate are not ideal.
Cadmium has an electrochemical potential of -0. 4030V. Lead has an electrochemical capacity of -0. 1262V. The electrochemical potential of cadmium is such that it prevents electroplating when a battery is standing. It is only when a battery is placed on gassing charge that the voltage at the unfavorable plate favors electroplating.
Copper has an electrochemical prospective Cu of +0. 5210V and Cu2 of +0. 3419V. Copper will merely plate onto the negatives regardless and stay there, triggering the plates to gas and to self discharge and to sulfate. The electrochemical capacities of aluminum, magnesium, potassium, sodium, etc. are all far to unfavorable, the metals far too reactive in battery acid, for anything of advantage to happen.
Bevan - It is not a theory. I ran the experiments. Constructed lead-acid cells in glass jars. I observed and measured (recondition dead battery). John- to my understanding, what you have done is an experiment- then forwarded an hypothesis to what you observed- then you advanced a theory- NOW-as to that theory to become FACT- your findings MUST be duplicated by other like minded individuals- can't see that happening right now- still, there is hope.
Bevan - I personally could not care less what individuals believe about sulfation. I ran an experiment designed to respond to yes or no, whether batteries can be desulfated. My experiment revealed that a person might get a quarter to a third short-term healing. I would not explain that as a "yes".
Others can quickly duplicate my expermiment. Humanity being what it is, some people so dislike an ugly truth getting in the way of a stunning story, their counter arguments will constantly remain in words, not deeds. The litmus test: Desulfation remains a struggling industry. Something is not best. There is no conspiracy.
If you want batteries to last longer, deal with them, help them while they are still functional, don't fuss over them after they "signed off". We do not feed medication to dead individuals. Why do it to batteries? The experiment is described on "CAN BATTERIES BE BROUGHT BACK". Well, anyone can state what they want about sulfation or desulfation, however including Epsom salt (service= 8 teaspoonfuls Epsom salts dissolved in 1 pint pure water) paired with a 3 day trickle charge assisted my truck battery maintain a much better charge.
The battery performed well through the winter after my treatment and is still going strong! I don't understand just how much longer it will live, however I will let you understand when it lastly passes away. Adios Shadmin - The part of the 1 pint of water that you handled to put into the battery helped; the three days additional drip charge helped; the Epsom salts satisfied your belief - how do you recondition a dead car battery.
ALL the so-called treatments incl epson, alum, cadmium, etc, etc, etc ad infinitum not do anything!!! However normally damage!! What many posters like to believe is that THEIR!!! treatment made a distinction!! BUT neglect all the other specifications of battery reaction incl temp, humidity etc in their attempt to understand a complicated subject!! (recondition old battery). The bare truth is that all automobile charge systems do not completely charge the l/a starter batt- however only around 14v- for a number of different factors.
Bevan - Where does the acid that raised your SG originated from? John- just returned on line after week after changing ISP!!! The increased sg is because of the dollop in the 15 ml added of Inox Mx2 to each cell! IT definitely is NOT due to decreasing sulfation & thus raising sg!. car battery reconditioning.
