That is quite typical. The silliest thing you can do is to put all kinds of sulfates into batteries in the hope of solving a problem. Urban legends will never ever die. Pencil lead can consist of some unusual compounds in addition to carbon (do i need to charge car battery after battery recondition). There are lots of carbon powder producers. Cars and truck 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 few years they are tossed out as NiCd is used out- simply cut around top 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 acquire Cadmium Sulphate, boil up some electrolyte- drop cadmium in- will bubble up & produce hazardous fumes- do outside -do not breathe vapours!!! When cadmium is totally liquified( & in some cases the electrolyte cadmium mix is a beautiful green, depending upon quality of cadmium from cell maker!)- task done! Got ta say- the mix I have contributed to batt cells does not seem 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; & try; in other batts to validate yes or no! Apart from that, the other thing is that the batt itself must be only lightly sulfated).
Still it is great at identifying o/c cell/s in batt- pulses increase higher with degree of o/c! have seen 1250 volts! Cut open, & broke down pos grid! in 1 cell-others almost so!. recondition a car battery. Bevan - I would suggest improving 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. 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 real voltage across the electroplating cell will be under 0. how to reconditioning car battery. 5V. The green you describe would be nickel contamination.
Bevan - That's innovative! Why didn't I think of that before? I will attempt it. John - You're one wise gentleman, thanks for the details. Bevan - I believe I might have at long last handled to determine what cadmium sulfate does. It definitely electroplates out onto the unfavorable grid metal when the battery is deliberately 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. Duplicated charging, discharging spreads the conductive environment gradually and gradually into the bulk of the lead sulfate. The process seems to have a limit. how to recondition an old battery. It would appear the trick to achieving 100% desulfation is to determine how to get conduction to spread out into 100% of the sulfate.
Including gradually more merely creates dendrites and causes shorts. The explanations offered 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 remains right where it is. It is transformed. While both positive and unfavorable plates can end up being sulfated, the positive sulfation merely reverses when the battery is charged.
John - If I comprehend you properly, did you suggested all the cadmium does is electroplating itself on the negative grid?If so, wouldn't just copper is great enough? Afdhal- it is simply John's theory- however i would say cadmium does not just plate itself- requirements driving- so does copper- BUT copper is a non laster in H2SO4! As are most metals! Lead lasts longer than many! Afdhal - No, copper and copper sulfate are not suitable.
Cadmium has an electrochemical capacity of -0. 4030V. Lead has an electrochemical potential 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 put on gassing charge that the voltage at the unfavorable plate favors electroplating.
Copper has an electrochemical possible 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 potentials 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 take place.
Bevan - It is not a theory. I ran the experiments. Developed lead-acid cells in glass jars. I observed and determined (how do you recondition a 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 TRUTH- your findings MUST be duplicated by other like minded individuals- can't see that happening just yet- still, there is hope.
Bevan - I personally might not care less what individuals suggest about sulfation. I ran an experiment designed to address yes or no, whether batteries can be desulfated. My experiment revealed that a person might get a quarter to a 3rd short-term recovery. I would not explain that as a "yes".
Others can quickly repeat my expermiment. Human nature being what it is, some people so dislike an unsightly truth obstructing of a beautiful story, their counter arguments will constantly be in words, not deeds. The litmus test: Desulfation stays a having a hard time industry. Something is wrong. There is no conspiracy.
If you desire batteries to last longer, work on them, assist them while they are still serviceable, 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 described on "CAN BATTERIES BE BROUGHT BACK". Well, anybody can say what they want about sulfation or desulfation, but adding Epsom salt (option= 8 teaspoonfuls Epsom salts dissolved in 1 pint pure water) coupled with a 3 day drip charge assisted my truck battery keep a much better charge.
The battery carried out 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 finally passes away. Adios Shadmin - The portion of the 1 pint of water that you managed to take into the battery assisted; the 3 days additional drip charge assisted; the Epsom salts pleased your belief - how to recondition a battery.
ALL the so-called remedies incl epson, alum, cadmium, etc, etc, etc advertisement infinitum not do anything!!! But normally hurt!! What many posters like to believe is that THEIR!!! treatment made a difference!! BUT ignore all the other parameters of battery response incl temperature, humidity etc in their effort to understand a complex subject!! (reconditioning a battery). The bare truth is that all vehicle charge systems do not totally charge the l/a starter batt- however just around 14v- for several different reasons.
Bevan - Where does the acid that raised your SG originated from? John- just returned on line after week after altering ISP!!! The increased sg is due to the dollop in the 15 ml added of Inox Mx2 to each cell! IT definitely is NOT due to reducing sulfation & hence raising sg!. what is in battery reconditioning solution.
