That is pretty common. The silliest thing you can do is to put all kinds of sulfates into batteries in the hope of resolving a problem. Urban legends will never die. Pencil lead can consist of some unusual compounds in addition to carbon (recondition car battery for sale). There are a lot of carbon powder producers. Automobile tires are about 50% carbon.
Does not cost an arm and a leg. Afdhal- I get cadmium from utilized NiCd cells-aaa or aa sizes- such as discovered in solar garden lights- after a few years they are thrown out as NiCd is used out- simply cut around leading crimp with hacksaw, decipher 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 & release poisonous fumes- do outside -do not breathe vapours!!! When cadmium is totally liquified( & often the electrolyte cadmium mix is a lovely green, depending on quality of cadmium from cell maker!)- job done! Got ta say- the mix I have contributed to batt cells does not seem to assist! In truth- I got ta say the ONLY thing I used that worked was INOX MX2( in 1 batt up until now- I will get some more MX2 &try; & shot; in other batts to confirm yes or no! Apart from that, the other thing is that the batt itself should be only gently sulfated).
Still it is proficient at recognizing o/c cell/s in batt- pulses increase greater with degree of o/c! have seen 1250 volts! Cut open, & broke down pos grid! in 1 cell-others nearly so!. do i need to charge car battery after 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. Source of power can be 12V battery. Insert 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. how do you recondition a battery. 5V. The green you explain would be nickel contamination.
Bevan - That's creative! Why didn't I think about that before? I will attempt it. John - You're one wise gentleman, thanks for the info. Bevan - I think I may have at long last managed to determine what cadmium sulfate does. It certainly electroplates out onto the negative grid metal when the battery is intentionally pushed into regulated overcharge.
This helps the lead sulfate nearest the grids to end up being active again and to be converted into lead and sulfate ions. Repeated charging, releasing spreads the conductive environment gradually and gradually into the bulk of the lead sulfate. The procedure seems to have a limit. how to recondition a 12v battery. It would appear the trick to attaining 100% desulfation is to find out how to get conduction to spread into 100% of the sulfate.
Including gradually more simply produces dendrites and triggers shorts. The descriptions given by desulation merchants that insoluble sulfation undoubtedly coats the plates when batteries are used which their treatment strips it away is pure fantasy. The sulfate remains right where it is. It is transformed. While both positive and negative plates can end up being sulfated, the positive sulfation merely reverses when the battery is charged.
John - If I understand you properly, did you meant all the cadmium does is electroplating itself on the negative grid?If so, would not simply copper is excellent enough? Afdhal- it is just John's theory- however i would state 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 suitable.
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 avoids electroplating when a battery is standing. It is only when a battery is put on gassing charge that the voltage at the unfavorable plate favors electroplating.
Copper has an electrochemical potential Cu of +0. 5210V and Cu2 of +0. 3419V. Copper will merely plate onto the negatives regardless and remain there, causing the plates to gas and to self discharge and to sulfate. The electrochemical capacities 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. Developed lead-acid cells in glass jars. I observed and measured (how to restore a dead battery car). John- to my knowledge, 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 end up being REALITY- your findings MUST be duplicated by other like minded individuals- can't see that taking place just yet- still, there is hope.
Bevan - I personally could not care less what individuals opine about sulfation. I ran an experiment designed to address yes or no, whether batteries can be desulfated. My experiment revealed that a person may get a quarter to a third short-term healing. I would not describe that as a "yes".
Others can quickly repeat my expermiment. Human nature being what it is, some people so do not like an unsightly truth getting in the method of a stunning story, their counter arguments will always remain in words, not deeds. The base test: Desulfation remains a having a hard time market. Something is wrong. There is no conspiracy.
If you desire batteries to last longer, work on them, help them while they are still functional, do not 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 BROUGHT BACK". Well, anybody can state what they desire about sulfation or desulfation, however including Epsom salt (solution= 8 teaspoonfuls Epsom salts liquified in 1 pint pure water) paired with a 3 day trickle charge helped my truck battery keep 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, but I will let you know when it lastly passes away. Adios Shadmin - The portion of the 1 pint of water that you handled to take into the battery assisted; the 3 days extra trickle charge helped; the Epsom salts pleased your belief - how to recondition a 12v battery.
ALL the so-called solutions incl epson, alum, cadmium, etc, etc, etc ad infinitum not do anything!!! However typically harm!! What numerous posters like to think is that THEIR!!! treatment made a distinction!! BUT overlook all the other parameters of battery response incl temp, humidity etc in their effort to make sense of a complex subject!! (how to restore a dead car battery). The bare reality is that all vehicle charge systems do not completely charge the l/a starter batt- but only around 14v- for several different reasons.
Bevan - Where does the acid that raised your SG originated from? John- just got back on line after week after altering ISP!!! The increased sg is due to the dollop in the 15 ml included of Inox Mx2 to each cell! IT absolutely is NOT due to decreasing sulfation & therefore raising sg!. how to recondition a car battery.
