That is pretty typical. The silliest thing you can do is to put all type of sulfates into batteries in the hope of fixing an issue. Urban myth will never die. Pencil lead can contain some unusual compounds in addition to carbon (how to recondition a 12v battery). There are a lot of carbon powder producers. Automobile tyres 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 couple of years they are tossed out as NiCd is worn out- just cut around leading crimp with hacksaw, decipher s/s case with cutter, withdraw contents- outer 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 & emit poisonous fumes- do outside -do not breathe vapours!!! When cadmium is totally dissolved( & sometimes the electrolyte cadmium mix is a charming green, depending upon quality of cadmium from cell maker!)- job done! Got ta say- the mix I have added to batt cells does not seem to assist! In reality- I got ta state the ONLY thing I utilized that worked was INOX MX2( in 1 batt up until now- I will get some more MX2 &try; & try; in other batts to confirm yes or no! Apart from that, the other thing is that the batt itself must be only lightly sulfated).
Still it is excellent 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 nearly so!. how do you recondition a battery. Bevan - I would suggest fine-tuning the cadmium by making the cadmium you recovered from the NiCds the favorable in an electroplating cell.
Utilize 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. recondition old battery. 5V. The green you explain would be nickel contamination.
Bevan - That's imaginative! Why didn't I consider that prior to? I will attempt it. John - You're one wise gentleman, thanks for the info. Bevan - I think I may have at long last handled to determine what cadmium sulfate does. It definitely electroplates out onto the negative grid metal when the battery is deliberately pressed into controlled 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, releasing spreads the conductive environment gradually and gradually into the bulk of the lead sulfate. The process seems to have a limit. how to recondition any battery. It would appear the secret to achieving 100% desulfation is to find out how to get conduction to spread into 100% of the sulfate.
Adding gradually more merely develops dendrites and causes shorts. The explanations given by desulation merchants that insoluble sulfation undoubtedly coats the plates when batteries are utilized which their treatment strips it away is pure fantasy. The sulfate stays right where it is. It is transformed. While both favorable and negative plates can end up being sulfated, the favorable sulfation just reverses when the battery is charged.
John - If I understand you correctly, did you implied all the cadmium does is electroplating itself on the negative grid?If so, wouldn't just copper suffices? Afdhal- it is simply John's theory- but 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 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 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 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 happen.
Bevan - It is not a theory. I ran the experiments. Built lead-acid cells in glass containers. I observed and determined (recondition a car battery). 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 become REALITY- your findings MUST be replicated by other like minded individuals- can't see that occurring simply yet- still, there is hope.
Bevan - I personally could not care less what people opine about sulfation. I ran an experiment created to respond to yes or no, whether batteries can be desulfated. My experiment showed that one might get a quarter to a 3rd short-term healing. I would not explain that as a "yes".
Others can easily duplicate my expermiment. Humanity being what it is, some people so do not like an ugly fact getting in the method of a beautiful story, their counter arguments will constantly be in words, not deeds. The litmus test: Desulfation stays a struggling industry. Something is wrong. There is no conspiracy.
If you want batteries to last longer, deal with them, help them while they are still serviceable, don't fuss over them after they "signed off". We do not feed medicine to dead individuals. Why do it to batteries? The experiment is explained on "CAN BATTERIES BE BROUGHT BACK". Well, anyone can say what they desire about sulfation or desulfation, but including Epsom salt (solution= 8 teaspoonfuls Epsom salts dissolved in 1 pint pure water) coupled with a 3 day trickle charge helped my truck battery maintain a much better charge.
The battery carried out well through the winter season 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 finally dies. Adios Shadmin - The part of the 1 pint of water that you handled to take into the battery assisted; the three days additional drip charge helped; the Epsom salts pleased your belief - how to recondition a dead car battery.
ALL the so-called treatments incl epson, alum, cadmium, etc, etc, etc ad infinitum not do anything!!! However normally harm!! What lots of posters like to believe is that THEIR!!! treatment made a distinction!! BUT neglect all the other specifications of battery response incl temperature, humidity etc in their attempt to understand a complicated subject!! (battery reconditioning com). The bare reality is that all vehicle charge systems do not fully charge the l/a starter batt- however just around 14v- for numerous various factors.
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!. materials needed to recondition car battery.
