That is quite common. The silliest thing you can do is to put all sort of sulfates into batteries in the hope of fixing a problem. Urban legends will never pass away. Pencil lead can contain some unusual substances in addition to carbon (do i need to charge car battery after battery recondition). There are plenty of carbon powder makers. Cars and truck 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 discovered in solar garden lights- after a couple of years they are thrown away as NiCd is broken- merely 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 obtain Cadmium Sulphate, boil up some electrolyte- drop cadmium in- will bubble up & release toxic fumes- do outside -do not breathe vapours!!! When cadmium is entirely liquified( & in some cases the electrolyte cadmium mix is a lovely green, depending on quality of cadmium from cell maker!)- task done! Got ta state- the mix I have contributed to batt cells does not seem to assist! 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; & shot; in other batts to verify yes or no! Apart from that, the other thing is that the batt itself must be only gently sulfated).
Still it is good at determining 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!. how to recondition a wore out battery. Bevan - I would recommend fine-tuning the cadmium by making the cadmium you recuperated from the NiCds the favorable in an electroplating cell.
Utilize a tin wire or solder wire negative. Source of power can be 12V battery. Place 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. battery reconditioning com. 5V. The green you explain would be nickel contamination.
Bevan - That's innovative! Why didn't I consider that prior to? I will attempt it. John - You're one smart gentleman, thanks for the information. Bevan - I believe I may have at long last handled to find out what cadmium sulfate does. It certainly electroplates out onto the unfavorable grid metal when the battery is intentionally pressed into regulated overcharge.
This helps the lead sulfate nearest the grids to end up being active again and to be converted into lead and sulfate ions. Repeated charging, releasing spreads the conductive environment gradually and progressively into the bulk of the lead sulfate. The process appears to have a limitation. how to reconditioning car battery. It would appear the secret to achieving 100% desulfation is to figure out how to get conduction to spread into 100% of the sulfate.
Including progressively more simply creates dendrites and triggers shorts. The explanations given by desulation merchants that insoluble sulfation undoubtedly 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 favorable and negative plates can end up being sulfated, the positive sulfation merely reverses when the battery is charged.
John - If I understand you correctly, did you suggested all the cadmium does is electroplating itself on the unfavorable grid?If so, wouldn't simply copper is great enough? Afdhal- it is just John's theory- but 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 many! Afdhal - No, copper and copper sulfate are not appropriate.
Cadmium has an electrochemical capacity of -0. 4030V. Lead has an electrochemical capacity of -0. 1262V. The electrochemical capacity 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 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 stay there, causing the plates to gas and to self discharge and to sulfate. The electrochemical capacities of aluminum, magnesium, potassium, salt, and so on are all far to negative, 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 containers. I observed and measured (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 FACT- your findings MUST be replicated by other like minded individuals- can't see that occurring right now- still, there is hope.
Bevan - I personally might not care less what individuals believe about sulfation. I ran an experiment designed to address yes or no, whether batteries can be desulfated. My experiment showed that one might get a quarter to a third short-term recovery. I would not describe that as a "yes".
Others can quickly repeat my expermiment. Humanity being what it is, some individuals so dislike an unsightly truth getting in the way of a gorgeous story, their counter arguments will constantly remain in words, not deeds. The litmus test: Desulfation remains a struggling industry. Something is not ideal. There is no conspiracy.
If you desire batteries to last longer, deal with them, assist them while they are still functional, 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 described on "CAN BATTERIES BE RESTORED". Well, anybody can say what they desire about sulfation or desulfation, but adding Epsom salt (option= 8 teaspoonfuls Epsom salts liquified in 1 pint distilled water) paired with a 3 day trickle charge assisted my truck battery keep a better charge.
The battery carried out well through the winter season after my treatment and is still going strong! I do not understand how much longer it will live, however I will let you know when it lastly passes away. Adios Shadmin - The portion of the 1 pint of water that you managed to take into the battery assisted; the three days additional drip charge assisted; the Epsom salts satisfied your belief - reconditioning a 12 volt truck battery.
ALL the so-called remedies incl epson, alum, cadmium, etc, etc, etc ad infinitum do NOTHING!!! However usually harm!! What many posters like to think is that THEIR!!! treatment made a distinction!! BUT overlook all the other criteria of battery action incl temperature, humidity etc in their effort to make sense of a complex subject!! (reconditioning old battery). The bare reality is that all automobile charge systems do not completely charge the l/a starter batt- however just around 14v- for several various reasons.
Bevan - Where does the acid that raised your SG come from? John- simply got back on line after week after changing ISP!!! The increased sg is due to the dollop in the 15 ml added of Inox Mx2 to each cell! IT certainly is NOT due to reducing sulfation & hence raising sg!. how do you recondition a dead battery.
