That is quite typical. The silliest thing you can do is to put all type of sulfates into batteries in the hope of fixing an issue. Urban myth will never pass away. Pencil lead can contain some weird compounds in addition to carbon (how to recondition an old battery). There are plenty of carbon powder manufacturers. Vehicle tires have to do with 50% carbon.
Does not cost an arm and a leg. Afdhal- I get cadmium from used NiCd cells-aaa or aa sizes- such as discovered in solar garden lights- after a couple of years they are tossed out as NiCd is broken- simply cut around leading crimp with hacksaw, unwind s/s case with cutter, withdraw contents- external foil is cadmium, inner foil is nickel, & some solid electrolyte & seperator- all wound in spiral pattern.
To obtain Cadmium Sulphate, boil up some electrolyte- drop cadmium in- will bubble up & offer off toxic fumes- do outdoors -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!)- job done! Got ta say- the mix I have added to batt cells does not appear to assist! In fact- I got ta say the ONLY thing I utilized that worked was INOX MX2( in 1 batt up until now- I will get some more MX2 &try; & try; in other batts to verify yes or no! Apart from that, the other thing is that the batt itself should be only lightly sulfated).
Still it is great at recognizing o/c cell/s in batt- pulses increase greater with degree of o/c! have actually seen 1250 volts! Cut open, & broke down pos grid! in 1 cell-others practically so!. how to recondition a battery at home. Bevan - I would recommend fine-tuning the cadmium by making the cadmium you recovered from the NiCds the positive in an electroplating cell.
Utilize a tin wire or solder wire unfavorable. Power source 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 battery. 5V. The green you describe would be nickel contamination.
Bevan - That's innovative! Why didn't I think about that prior to? I will try it. John - You're one clever gentleman, thanks for the info. Bevan - I think I may have at long last managed to figure out what cadmium sulfate does. It absolutely electroplates out onto the unfavorable grid metal when the battery is intentionally pressed into controlled overcharge.
This assists the lead sulfate nearest the grids to end up being active once again and to be converted into lead and sulfate ions. Duplicated charging, discharging spreads the conductive environment slowly and progressively into the bulk of the lead sulfate. The process appears to have a limit. materials needed to recondition car 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.
Adding progressively more simply produces dendrites and triggers shorts. The explanations provided by desulation merchants that insoluble sulfation inevitably coats the plates when batteries are utilized and that their treatment strips it away is pure dream. The sulfate stays right where it is. It is converted. While both positive and unfavorable plates can end up being sulfated, the favorable sulfation merely 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, would not just copper suffices? 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 the majority of! Afdhal - No, copper and copper sulfate are not appropriate.
Cadmium has an electrochemical capacity of -0. 4030V. Lead has an electrochemical capacity of -0. 1262V. The electrochemical potential of cadmium is such that it avoids electroplating when a battery is standing. It is just when a battery is put on gassing charge that the voltage at the negative plate favors electroplating.
Copper has an electrochemical prospective Cu of +0. 5210V and Cu2 of +0. 3419V. Copper will simply plate onto the negatives regardless and remain there, causing the plates to gas and to self discharge and to sulfate. The electrochemical potentials of aluminum, magnesium, potassium, salt, etc. are all far to unfavorable, the metals far too reactive in battery acid, for anything of benefit to take place.
Bevan - It is not a theory. I ran the experiments. Built lead-acid cells in glass containers. I observed and measured (recondition a battery). John- to my knowledge, 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 end up being REALITY- your findings MUST be reproduced by other like minded persons- can't see that happening simply yet- still, there is hope.
Bevan - I personally could not care less what people suggest about sulfation. I ran an experiment developed to answer yes or no, whether batteries can be desulfated. My experiment showed that a person may get a quarter to a third short-term healing. I would not describe that as a "yes".
Others can easily repeat my expermiment. Human nature being what it is, some individuals so dislike an awful fact obstructing of a beautiful story, their counter arguments will always be in words, not deeds. The base test: Desulfation remains a struggling market. Something is wrong. There is no conspiracy.
If you want batteries to last longer, work on them, assist them while they are still functional, don't fuss over them after they "signed off". We don't feed medication to dead individuals. Why do it to batteries? The experiment is explained on "CAN BATTERIES BE RESTORED". Well, anyone can state what they want about sulfation or desulfation, however including Epsom salt (option= 8 teaspoonfuls Epsom salts liquified in 1 pint distilled water) combined with a 3 day trickle charge assisted my truck battery maintain a better charge.
The battery carried out well through the winter season after my treatment and is still going strong! I do not know how much longer it will live, however I will let you know when it finally passes away. Adios Shadmin - The portion of the 1 pint of water that you managed to put into the battery assisted; the three days additional trickle charge assisted; the Epsom salts pleased your belief - how to recondition a car battery.
ALL the so-called remedies incl epson, alum, cadmium, etc, etc, etc ad infinitum not do anything!!! But usually hurt!! What numerous posters like to believe is that THEIR!!! treatment made a difference!! BUT neglect all the other parameters of battery reaction incl temperature, humidity etc in their attempt to make sense of a complex subject!! (how to recondition a battery at home). The bare truth is that all vehicle charge systems do not fully charge the l/a starter batt- however only around 14v- for several different factors.
Bevan - Where does the acid that raised your SG originated 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 absolutely is NOT due to minimizing sulfation & therefore raising sg!. what is battery reconditioning.
