That is pretty typical. The silliest thing you can do is to put all type of sulfates into batteries in the hope of resolving a problem. Urban myth will never ever die. Pencil lead can contain some odd substances in addition to carbon (what is battery reconditioning). There are lots of carbon powder makers. Vehicle tires are about 50% carbon.
Does not cost an arm and a leg. Afdhal- I get cadmium from used NiCd cells-aaa or aa sizes- such as found in solar garden lights- after a few years they are tossed out as NiCd is worn out- merely cut around leading crimp with hacksaw, decipher s/s case with cutter, withdraw contents- outer foil is cadmium, inner foil is nickel, & some solid electrolyte & seperator- all injury in spiral pattern.
To obtain Cadmium Sulphate, boil up some electrolyte- drop cadmium in- will bubble up & emit poisonous fumes- do outdoors -do not breathe vapours!!! When cadmium is entirely liquified( & often the electrolyte cadmium mix is a lovely green, depending on quality of cadmium from cell maker!)- job done! Got ta state- the mix I have added to batt cells does not appear to assist! In reality- I got ta say the ONLY thing I utilized that worked was INOX MX2( in 1 batt so far- I will get some more MX2 &try; & shot; in other batts to verify yes or no! Apart from that, the other thing is that the batt itself must be only lightly sulfated).
Still it is great at recognizing o/c cell/s in batt- pulses go up greater with degree of o/c! have actually seen 1250 volts! Cut open, & broke down pos grid! in 1 cell-others almost so!. automotive battery reconditioning. Bevan - I would suggest fine-tuning 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. Source of power can be 12V battery. Place 220 ohm series resistor. The cadmium that gets plated onto the negative will be dendritic and pure. The actual voltage throughout the electroplating cell will be under 0. reconditioning car battery. 5V. The green you explain would be nickel contamination.
Bevan - That's innovative! Why didn't I consider that prior to? I will try it. John - You're one smart gentleman, thanks for the info. Bevan - I think I may have at long last handled to find out what cadmium sulfate does. It certainly electroplates out onto the unfavorable grid metal when the battery is intentionally pressed into controlled overcharge.
This helps the lead sulfate nearest the grids to become active again and to be converted into lead and sulfate ions. Repeated charging, discharging spreads the conductive environment slowly and gradually into the bulk of the lead sulfate. The procedure appears to have a limit. what is battery reconditioning. It would appear the secret to accomplishing 100% desulfation is to determine how to get conduction to spread out into 100% of the sulfate.
Including progressively more simply creates dendrites and triggers shorts. The descriptions provided by desulation merchants that insoluble sulfation inevitably 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 converted. While both favorable and unfavorable plates can end up being sulfated, the favorable sulfation just reverses when the battery is charged.
John - If I understand you properly, did you implied all the cadmium does is electroplating itself on the unfavorable grid?If so, wouldn't just copper suffices? Afdhal- it is simply John's theory- however i would say cadmium does not simply plate itself- needs driving- so does copper- BUT copper is a non laster in H2SO4! As are most metals! Lead lasts longer than the majority of! Afdhal - No, copper and copper sulfate are not ideal.
Cadmium has an electrochemical capacity of -0. 4030V. Lead has an electrochemical potential of -0. 1262V. The electrochemical capacity of cadmium is such that it prevents electroplating when a battery is standing. It is just when a battery is put on gassing charge that the voltage at the negative plate prefers electroplating.
Copper has an electrochemical prospective Cu of +0. 5210V and Cu2 of +0. 3419V. Copper will merely plate onto the negatives regardless and remain there, triggering the plates to gas and to self discharge and to sulfate. The electrochemical capacities of aluminum, magnesium, potassium, sodium, and so on are all far to unfavorable, the metals far too reactive in battery acid, for anything of advantage to occur.
Bevan - It is not a theory. I ran the experiments. Developed lead-acid cells in glass containers. I observed and determined (recondition dead battery). John- to my understanding, what you have actually 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 occurring right now- still, there is hope.
Bevan - I personally could not care less what people believe about sulfation. I ran an experiment created to answer yes or no, whether batteries can be desulfated. My experiment showed that one might get a quarter to a 3rd short-term healing. I would not describe that as a "yes".
Others can easily repeat my expermiment. Humanity being what it is, some people so do not like an awful reality getting in the method of a beautiful story, their counter arguments will always remain in words, not deeds. The litmus test: Desulfation remains a struggling industry. Something is wrong. There is no conspiracy.
If you want batteries to last longer, deal with them, assist them while they are still serviceable, don't fuss over them after they "signed off". We don't feed medicine to dead individuals. Why do it to batteries? The experiment is described on "CAN BATTERIES BE BROUGHT BACK". Well, anyone can say what they want about sulfation or desulfation, however including Epsom salt (solution= 8 teaspoonfuls Epsom salts liquified in 1 pint pure water) combined with a 3 day trickle charge helped my truck battery keep a better charge.
The battery carried out well through the winter after my treatment and is still going strong! I do not know just how much longer it will live, however I will let you know when it finally dies. Adios Shadmin - The portion of the 1 pint of water that you handled to take into the battery assisted; the 3 days additional drip charge assisted; the Epsom salts satisfied your belief - 12 volt battery reconditioning.
ALL the so-called solutions incl epson, alum, cadmium, etc, etc, etc advertisement infinitum not do anything!!! However generally harm!! What numerous posters like to believe is that THEIR!!! treatment made a distinction!! BUT neglect all the other criteria of battery response incl temp, humidity etc in their attempt to make sense of a complicated subject!! (is it okay to recondition a car battery with it still connected). The bare fact is that all vehicle charge systems do not fully charge the l/a starter batt- however only around 14v- for numerous different factors.
Bevan - Where does the acid that raised your SG come from? John- simply got back on line after week after altering ISP!!! The increased sg is because of the dollop in the 15 ml added of Inox Mx2 to each cell! IT certainly is NOT due to lowering sulfation & thus raising sg!. how do you recondition a battery.
