That is pretty typical. The silliest thing you can do is to put all kinds of sulfates into batteries in the hope of resolving a problem. Urban legends will never ever pass away. Pencil lead can contain some odd substances in addition to carbon (how to recondition a battery at home). There are a lot of carbon powder makers. Car tires 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 found in solar garden lights- after a couple of years they are thrown away as NiCd is broken- just cut around top crimp with hacksaw, unravel s/s case with cutter, withdraw contents- external foil is cadmium, inner foil is nickel, & some strong electrolyte & seperator- all injury in spiral pattern.
To acquire Cadmium Sulphate, boil up some electrolyte- drop cadmium in- will bubble up & emit harmful fumes- do outdoors -do not breathe vapours!!! When cadmium is completely liquified( & in some cases the electrolyte cadmium mix is a beautiful green, depending upon quality of cadmium from cell maker!)- task done! Got ta say- the mix I have added to batt cells does not seem to help! In fact- 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 need to be just gently sulfated).
Still it is proficient at determining 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!. how do you recondition a car battery. Bevan - I would suggest improving the cadmium by making the cadmium you recuperated from the NiCds the positive in an electroplating cell.
Utilize 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 negative will be dendritic and pure. The actual voltage across the electroplating cell will be under 0. recondition battery guide. 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 clever gentleman, thanks for the info. Bevan - I believe I may have at long last managed to find out what cadmium sulfate does. It definitely electroplates out onto the negative grid metal when the battery is deliberately pushed into regulated overcharge.
This assists the lead sulfate nearest the grids to become active again and to be converted into lead and sulfate ions. Repeated charging, discharging spreads the conductive environment slowly and gradually into the bulk of the lead sulfate. The process appears to have a limit. what is battery reconditioning. It would appear the secret to achieving 100% desulfation is to determine how to get conduction to spread out into 100% of the sulfate.
Including gradually more simply produces dendrites and triggers shorts. The descriptions given by desulation merchants that insoluble sulfation inevitably coats the plates when batteries are utilized and that their treatment strips it away is pure fantasy. The sulfate remains right where it is. It is converted. While both favorable and unfavorable plates can become sulfated, the positive sulfation merely reverses when the battery is charged.
John - If I understand you properly, did you implied all the cadmium does is electroplating itself on the unfavorable grid?If so, wouldn't simply copper is excellent enough? Afdhal- it is just 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 most! 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 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 unfavorable plate favors 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, 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 negative, the metals far too reactive in battery acid, for anything of advantage to occur.
Bevan - It is not a theory. I ran the experiments. Constructed lead-acid cells in glass jars. I observed and measured (recondition your old 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 become REALITY- your findings MUST be replicated by other like minded individuals- can't see that occurring just yet- still, there is hope.
Bevan - I personally might not care less what people believe about sulfation. I ran an experiment designed to address yes or no, whether batteries can be desulfated. My experiment revealed that a person might get a quarter to a third short-term recovery. I would not explain that as a "yes".
Others can easily repeat my expermiment. Human nature being what it is, some people so do not like an ugly truth obstructing of a lovely story, their counter arguments will constantly remain in words, not deeds. The litmus test: Desulfation remains a struggling market. 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, do not fuss over them after they "signed off". We do not feed medication 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 including Epsom salt (service= 8 teaspoonfuls Epsom salts liquified in 1 pint pure water) coupled with a 3 day trickle charge helped my truck battery keep a better charge.
The battery carried out well through the winter after my treatment and is still going strong! I do not know just how much longer it will live, however I will let you know when it lastly passes away. Adios Shadmin - The part of the 1 pint of water that you managed to put into the battery helped; the 3 days extra drip charge helped; the Epsom salts satisfied your belief - do i need to charge car battery after battery recondition.
ALL the so-called solutions incl epson, alum, cadmium, etc, etc, etc ad infinitum not do anything!!! However generally hurt!! 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 effort to understand a complex subject!! (how to recondition an old battery). The bare reality is that all automobile charge systems do not fully charge the l/a starter batt- but just around 14v- for numerous different factors.
Bevan - Where does the acid that raised your SG originated from? John- simply got back on line after week after altering ISP!!! The increased sg is due to the dollop in the 15 ml included of Inox Mx2 to each cell! IT certainly is NOT due to minimizing sulfation & therefore raising sg!. do i need to charge car battery after battery recondition.
