That is pretty common. The silliest thing you can do is to put all sort of sulfates into batteries in the hope of resolving an issue. Urban legends will never ever pass away. Pencil lead can include some strange substances in addition to carbon (what is in battery reconditioning solution). There are a lot of carbon powder producers. Vehicle tyres 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 found in solar garden lights- after a couple of years they are thrown away as NiCd is worn- simply cut around top crimp with hacksaw, unwind s/s case with cutter, withdraw contents- outer foil is cadmium, inner foil is nickel, & some strong 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 outside -do not breathe vapours!!! When cadmium is completely dissolved( & in some cases 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 appear to assist! In truth- 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 should be just lightly sulfated).
Still it is proficient at identifying o/c cell/s in batt- pulses increase higher with degree of o/c! have seen 1250 volts! Cut open, & disintegrated pos grid! in 1 cell-others nearly so!. how to reconditioning car battery. Bevan - I would suggest fine-tuning the cadmium by making the cadmium you recuperated from the NiCds the positive in an electroplating cell.
Utilize a tin wire or solder wire unfavorable. Source of power can be 12V battery. Insert 220 ohm series resistor. The cadmium that gets plated onto the unfavorable will be dendritic and pure. The actual voltage across the electroplating cell will be under 0. battery recondition. 5V. The green you describe would be nickel contamination.
Bevan - That's innovative! Why didn't I believe of that before? I will try it. John - You're one smart gentleman, thanks for the details. Bevan - I believe I might have at long last handled to find out what cadmium sulfate does. It definitely electroplates out onto the unfavorable grid metal when the battery is intentionally pushed into regulated overcharge.
This helps the lead sulfate nearest the grids to end up being active once again and to be transformed into lead and sulfate ions. Repeated charging, releasing spreads the conductive environment slowly and gradually into the bulk of the lead sulfate. The procedure appears to have a limitation. recondition a car battery. It would appear the secret to attaining 100% desulfation is to determine how to get conduction to spread into 100% of the sulfate.
Including gradually more simply develops dendrites and causes shorts. The explanations offered 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 transformed. While both positive and unfavorable plates can become sulfated, the favorable sulfation simply reverses when the battery is charged.
John - If I comprehend you properly, did you indicated all the cadmium does is electroplating itself on the negative grid?If so, would not simply copper is great enough? Afdhal- it is just 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 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 avoids electroplating when a battery is standing. It is just when a battery is put 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 simply plate onto the negatives regardless and stay 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 negative, the metals far too reactive in battery acid, for anything of benefit to occur.
Bevan - It is not a theory. I ran the experiments. Built lead-acid cells in glass containers. I observed and determined (what is in battery reconditioning solution). 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 TRUTH- your findings MUST be duplicated by other like minded persons- can't see that occurring right now- still, there is hope.
Bevan - I personally could not care less what individuals suggest about sulfation. I ran an experiment designed to respond to yes or no, whether batteries can be desulfated. My experiment showed that one may get a quarter to a third short-term recovery. I would not explain that as a "yes".
Others can quickly duplicate my expermiment. Humanity being what it is, some people so do not like an ugly truth obstructing of a stunning story, their counter arguments will constantly remain in words, not deeds. The base test: Desulfation stays a struggling industry. Something is not best. There is no conspiracy.
If you desire batteries to last longer, work on them, help them while they are still serviceable, 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 described on "CAN BATTERIES BE BROUGHT BACK". Well, anyone can state what they desire about sulfation or desulfation, but including Epsom salt (service= 8 teaspoonfuls Epsom salts liquified in 1 pint pure water) coupled with a 3 day trickle charge assisted my truck battery keep a better charge.
The battery performed well through the winter season after my treatment and is still going strong! I don't understand just how much longer it will live, but I will let you understand when it finally dies. Adios Shadmin - The part of the 1 pint of water that you handled to take into the battery helped; the 3 days additional trickle charge assisted; the Epsom salts pleased your belief - how to recondition a 12 volt battery.
ALL the so-called treatments incl epson, alum, cadmium, etc, etc, etc advertisement infinitum not do anything!!! However usually damage!! What numerous posters like to think is that THEIR!!! treatment made a difference!! BUT overlook all the other parameters of battery action incl temp, humidity etc in their effort to understand a complicated subject!! (recondition car battery for sale). The bare truth is that all automobile charge systems do not completely charge the l/a starter batt- however only around 14v- for several various reasons.
Bevan - Where does the acid that raised your SG come from? John- simply returned 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 & hence raising sg!. reconditioning battery.
