That is quite typical. The silliest thing you can do is to put all type of sulfates into batteries in the hope of solving a problem. Urban myth will never ever pass away. Pencil lead can consist of some strange compounds in addition to carbon (auto battery reconditioning). There are lots of carbon powder makers. Automobile 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 worn- 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 injury in spiral pattern.
To get Cadmium Sulphate, boil up some electrolyte- drop cadmium in- will bubble up & emit poisonous fumes- do outdoors -do not breathe vapours!!! When cadmium is entirely liquified( & sometimes the electrolyte cadmium mix is a lovely green, depending on quality of cadmium from cell maker!)- job done! Got ta say- the mix I have actually included to batt cells does not seem to help! In reality- 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 confirm yes or no! Apart from that, the other thing is that the batt itself must be just gently sulfated).
Still it is proficient at identifying o/c cell/s in batt- pulses go up greater with degree of o/c! have seen 1250 volts! Cut open, & broke down pos grid! in 1 cell-others nearly so!. is it okay to recondition a car battery with it still connected. Bevan - I would suggest improving 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. 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 real voltage throughout the electroplating cell will be under 0. how to recondition an old battery. 5V. The green you explain would be nickel contamination.
Bevan - That's creative! Why didn't I consider that before? 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 figure out what cadmium sulfate does. It absolutely electroplates out onto the unfavorable grid metal when the battery is intentionally pressed into regulated overcharge.
This assists the lead sulfate nearest the grids to become active once again and to be transformed into lead and sulfate ions. Repeated charging, discharging spreads the conductive environment slowly and progressively into the bulk of the lead sulfate. The process appears to have a limit. how do you recondition a car battery. It would appear the trick to attaining 100% desulfation is to figure out how to get conduction to spread out into 100% of the sulfate.
Including gradually more just produces dendrites and causes shorts. The descriptions provided 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 stays right where it is. It is converted. While both positive and negative plates can end up being sulfated, the positive sulfation just reverses when the battery is charged.
John - If I comprehend you properly, did you indicated all the cadmium does is electroplating itself on the unfavorable grid?If so, would not just copper suffices? Afdhal- it is simply John's theory- but 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 the majority of! Afdhal - No, copper and copper sulfate are not appropriate.
Cadmium has an electrochemical potential of -0. 4030V. Lead has an electrochemical potential of -0. 1262V. The electrochemical capacity of cadmium is such that it avoids 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 simply plate onto the negatives regardless and remain there, causing 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 unfavorable, the metals far too reactive in battery acid, for anything of advantage to occur.
Bevan - It is not a theory. I ran the experiments. Built lead-acid cells in glass containers. I observed and determined (diy recondition car 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 replicated by other like minded individuals- can't see that happening right now- still, there is hope.
Bevan - I personally might not care less what individuals believe about sulfation. I ran an experiment developed to answer yes or no, whether batteries can be desulfated. My experiment showed that one may get a quarter to a third short-term recovery. I would not explain that as a "yes".
Others can quickly repeat my expermiment. Humanity being what it is, some individuals so dislike an ugly truth getting in the way of a lovely story, their counter arguments will constantly remain in words, not deeds. The base test: Desulfation remains a having a hard time market. Something is wrong. There is no conspiracy.
If you desire batteries to last longer, work on them, assist them while they are still serviceable, don't fuss over them after they "signed off". We do not 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 desire about sulfation or desulfation, but including Epsom salt (solution= 8 teaspoonfuls Epsom salts dissolved in 1 pint distilled water) paired with a 3 day trickle charge assisted my truck battery retain a better charge.
The battery carried out well through the winter after my treatment and is still going strong! I don't understand how much longer it will live, but I will let you know when it lastly dies. Adios Shadmin - The part of the 1 pint of water that you managed to take into the battery helped; the three days additional drip charge helped; the Epsom salts satisfied your belief - how to reconditioning car battery.
ALL the so-called solutions incl epson, alum, cadmium, etc, etc, etc advertisement infinitum do ABSOLUTELY NOTHING!!! However generally harm!! What lots of posters like to believe is that THEIR!!! treatment made a distinction!! BUT ignore all the other parameters of battery reaction incl temperature, humidity etc in their attempt to make sense of a complex subject!! (battery recondition). The bare fact is that all vehicle charge systems do not completely charge the l/a starter batt- however only around 14v- for numerous different reasons.
Bevan - Where does the acid that raised your SG come 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 absolutely is NOT due to reducing sulfation & therefore raising sg!. do i need to charge car battery after battery recondition.
