That is pretty typical. The silliest thing you can do is to put all kinds of sulfates into batteries in the hope of fixing an issue. Urban legends will never ever die. Pencil lead can consist of some strange compounds in addition to carbon (how to recondition an old battery). There are lots of carbon powder manufacturers. Cars and truck tires are about 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 tossed out as NiCd is worn- just cut around top crimp with hacksaw, unravel s/s case with cutter, withdraw contents- outer foil is cadmium, inner foil is nickel, & some strong electrolyte & seperator- all wound in spiral pattern.
To get Cadmium Sulphate, boil up some electrolyte- drop cadmium in- will bubble up & provide off toxic fumes- do outdoors -do not breathe vapours!!! When cadmium is completely liquified( & often the electrolyte cadmium mix is a beautiful green, depending upon quality of cadmium from cell maker!)- job done! Got ta state- the mix I have actually contributed to batt cells does not seem to help! 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; & try; 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 determining 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 almost so!. how to recondition a battery at home. Bevan - I would recommend improving the cadmium by making the cadmium you recuperated from the NiCds the favorable in an electroplating cell.
Use a tin wire or solder wire unfavorable. Power source 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 throughout the electroplating cell will be under 0. is it okay to recondition a car battery with it still connected. 5V. The green you describe would be nickel contamination.
Bevan - That's imaginative! Why didn't I consider that prior to? I will attempt it. John - You're one smart gentleman, thanks for the information. Bevan - I think I might have at long last handled to determine what cadmium sulfate does. It certainly electroplates out onto the unfavorable grid metal when the battery is deliberately pressed 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 slowly and gradually into the bulk of the lead sulfate. The process appears to have a limit. auto battery reconditioning. It would appear the secret to accomplishing 100% desulfation is to figure out how to get conduction to spread into 100% of the sulfate.
Including gradually more simply creates dendrites and triggers shorts. The descriptions provided by desulation merchants that insoluble sulfation undoubtedly 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 favorable and negative plates can become sulfated, the positive sulfation simply reverses when the battery is charged.
John - If I understand you correctly, did you meant all the cadmium does is electroplating itself on the unfavorable grid?If so, would not just copper is great enough? Afdhal- it is just John's theory- however i would say cadmium does not simply plate itself- needs 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 ideal.
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 just when a battery is placed on gassing charge that the voltage at the unfavorable plate prefers electroplating.
Copper has an electrochemical prospective Cu of +0. 5210V and Cu2 of +0. 3419V. Copper will merely 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, salt, etc. are all far to unfavorable, the metals far too reactive in battery acid, for anything of benefit to occur.
Bevan - It is not a theory. I ran the experiments. Constructed lead-acid cells in glass containers. I observed and measured (how to recondition a car 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 TRUTH- your findings MUST be reproduced by other like minded persons- can't see that taking place just yet- still, there is hope.
Bevan - I personally might not care less what people suggest about sulfation. I ran an experiment created to respond to yes or no, whether batteries can be desulfated. My experiment revealed that a person might get a quarter to a third short-term healing. I would not explain that as a "yes".
Others can quickly duplicate my expermiment. Humanity being what it is, some individuals so dislike an awful fact obstructing of a lovely story, their counter arguments will constantly be in words, not deeds. The base test: Desulfation remains a having a hard time market. Something is wrong. There is no conspiracy.
If you want batteries to last longer, deal with them, assist them while they are still functional, do not fuss over them after they "signed off". We don't feed medicine to dead individuals. Why do it to batteries? The experiment is described on "CAN BATTERIES BE BROUGHT BACK". Well, anybody can say what they desire about sulfation or desulfation, but adding Epsom salt (option= 8 teaspoonfuls Epsom salts liquified in 1 pint pure water) paired with a 3 day trickle charge helped my truck battery retain a much better charge.
The battery performed well through the winter after my treatment and is still going strong! I do not understand just how much longer it will live, however I will let you understand when it lastly dies. Adios Shadmin - The part of the 1 pint of water that you handled to take into the battery assisted; the 3 days additional drip charge helped; the Epsom salts satisfied your belief - battery reconditioning com.
ALL the so-called solutions incl epson, alum, cadmium, etc, etc, etc advertisement infinitum do ABSOLUTELY NOTHING!!! But normally hurt!! What many posters like to think is that THEIR!!! treatment made a difference!! BUT ignore all the other criteria of battery action incl temperature, humidity etc in their effort to make sense of a complicated subject!! (how to reconditioning car battery). The bare reality is that all vehicle charge systems do not fully charge the l/a starter batt- however just around 14v- for a number of different reasons.
Bevan - Where does the acid that raised your SG come from? John- simply returned on line after week after changing 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 & hence raising sg!. how to recondition a 12v battery.
