That is quite common. The silliest thing you can do is to put all type of sulfates into batteries in the hope of solving an issue. Urban legends will never pass away. Pencil lead can include some odd compounds in addition to carbon (reconditioning old battery). There are a lot of carbon powder makers. Cars and truck 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 few years they are thrown away as NiCd is broken- simply cut around top crimp with hacksaw, unravel s/s case with cutter, withdraw contents- external foil is cadmium, inner foil is nickel, & some solid electrolyte & seperator- all injury in spiral pattern.
To acquire Cadmium Sulphate, boil up some electrolyte- drop cadmium in- will bubble up & produce harmful fumes- do outside -do not breathe vapours!!! When cadmium is entirely dissolved( & sometimes the electrolyte cadmium mix is a beautiful green, depending on quality of cadmium from cell maker!)- job done! Got ta state- the mix I have actually included to batt cells does not seem to assist! In truth- I got ta state 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 validate yes or no! Apart from that, the other thing is that the batt itself must be only gently sulfated).
Still it is proficient at recognizing o/c cell/s in batt- pulses increase higher with degree of o/c! have actually seen 1250 volts! Cut open, & disintegrated pos grid! in 1 cell-others practically so!. reconditioning battery. Bevan - I would suggest 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 negative. Power source can be 12V battery. Insert 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 recondition a wore out battery. 5V. The green you describe would be nickel contamination.
Bevan - That's imaginative! Why didn't I think about that before? I will attempt it. John - You're one smart gentleman, thanks for the details. Bevan - I think I may have at long last managed to determine what cadmium sulfate does. It definitely electroplates out onto the negative grid metal when the battery is deliberately pressed into regulated overcharge.
This helps the lead sulfate nearest the grids to become 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 procedure appears to have a limitation. battery reconditioning com. It would appear the trick to attaining 100% desulfation is to determine how to get conduction to spread into 100% of the sulfate.
Including gradually more just develops dendrites and triggers shorts. The descriptions 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 converted. While both positive and negative plates can become sulfated, the favorable sulfation just reverses when the battery is charged.
John - If I comprehend you correctly, did you implied all the cadmium does is electroplating itself on the negative grid?If so, would not just copper is great 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 a lot of! Afdhal - No, copper and copper sulfate are not appropriate.
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 prevents electroplating when a battery is standing. It is just when a battery is placed on gassing charge that the voltage at the negative plate prefers electroplating.
Copper has an electrochemical possible Cu of +0. 5210V and Cu2 of +0. 3419V. Copper will simply 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 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. Developed lead-acid cells in glass jars. I observed and determined (battery reconditioning com). 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 TRUTH- your findings MUST be reproduced by other like minded individuals- can't see that happening right now- still, there is hope.
Bevan - I personally might 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 revealed that one may get a quarter to a 3rd short-term recovery. 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 fact getting in the method of a lovely story, their counter arguments will always remain in words, not deeds. The base test: Desulfation stays 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 medicine to dead people. Why do it to batteries? The experiment is explained on "CAN BATTERIES BE BROUGHT BACK". Well, anybody can state what they want about sulfation or desulfation, but adding Epsom salt (solution= 8 teaspoonfuls Epsom salts liquified in 1 pint distilled water) combined with a 3 day trickle charge helped 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, but I will let you understand when it lastly passes away. Adios Shadmin - The part of the 1 pint of water that you handled to put into the battery helped; the three days extra trickle charge assisted; the Epsom salts pleased your belief - how to recondition a wore out battery.
ALL the so-called treatments incl epson, alum, cadmium, etc, etc, etc ad infinitum not do anything!!! However normally damage!! What many posters like to think is that THEIR!!! treatment made a difference!! BUT ignore all the other parameters of battery response incl temp, humidity etc in their attempt to make sense of a complicated subject!! (recondition dead battery). The bare fact is that all automobile charge systems do not fully charge the l/a starter batt- however just around 14v- for a number of different factors.
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 included of Inox Mx2 to each cell! IT absolutely is NOT due to lowering sulfation & hence raising sg!. 12 volt battery reconditioning.
