That is pretty common. The silliest thing you can do is to put all kinds of sulfates into batteries in the hope of solving an issue. Urban myth will never pass away. Pencil lead can include some odd compounds in addition to carbon (reconditioning a 12 volt truck battery). There are a lot of carbon powder manufacturers. Vehicle tyres have to do with 50% carbon.

Does not cost an arm and a leg. Afdhal- I get cadmium from used NiCd cells-aaa or aa sizes- such as found in solar garden lights- after a few years they are thrown away as NiCd is broken- just cut around top crimp with hacksaw, unwind s/s case with cutter, withdraw contents- outer foil is cadmium, inner foil is nickel, & some solid electrolyte & seperator- all wound in spiral pattern.

To obtain Cadmium Sulphate, boil up some electrolyte- drop cadmium in- will bubble up & emit poisonous fumes- do outside -do not breathe vapours!!! When cadmium is completely dissolved( & often 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 appear 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; & shot; in other batts to confirm yes or no! Apart from that, the other thing is that the batt itself need to be only lightly sulfated).

Still it is good at recognizing o/c cell/s in batt- pulses go up higher with degree of o/c! have seen 1250 volts! Cut open, & disintegrated pos grid! in 1 cell-others practically so!. recondition a car battery. Bevan - I would recommend refining the cadmium by making the cadmium you recuperated from the NiCds the positive in an electroplating cell.

How To Recondition Any Battery

Use a tin wire or solder wire unfavorable. Source of power can be 12V battery. Place 220 ohm series resistor. The cadmium that gets plated onto the unfavorable will be dendritic and pure. The real voltage across the electroplating cell will be under 0. recondition car battery for sale. 5V. The green you describe would be nickel contamination.

Bevan - That's innovative! Why didn't I think about that prior to? I will try it. John - You're one clever gentleman, thanks for the information. Bevan - I think I might have at long last handled to determine what cadmium sulfate does. It absolutely electroplates out onto the negative grid metal when the battery is deliberately pushed into controlled overcharge.

This assists the lead sulfate nearest the grids to end up being active once again and to be converted into lead and sulfate ions. Repeated charging, discharging spreads the conductive environment gradually and gradually into the bulk of the lead sulfate. The procedure appears to have a limitation. recondition old battery. It would appear the secret to attaining 100% desulfation is to figure out how to get conduction to spread into 100% of the sulfate.

Adding gradually more just creates dendrites and triggers shorts. The explanations provided by desulation merchants that insoluble sulfation inevitably coats the plates when batteries are utilized which their treatment strips it away is pure dream. The sulfate remains right where it is. It is converted. While both positive and unfavorable 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 unfavorable grid?If so, would not simply copper suffices? 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 a lot of! Afdhal - No, copper and copper sulfate are not suitable.

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 avoids electroplating when a battery is standing. It is only when a battery is placed 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 just plate onto the negatives regardless and stay there, triggering the plates to gas and to self discharge and to sulfate. The electrochemical potentials of aluminum, magnesium, potassium, sodium, etc. 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. Constructed lead-acid cells in glass jars. I observed and determined (recondition car battery for sale). 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 end up being TRUTH- your findings MUST be reproduced by other like minded individuals- can't see that taking place simply yet- still, there is hope.

Bevan - I personally could not care less what individuals believe about sulfation. I ran an experiment designed to respond to yes or no, whether batteries can be desulfated. My experiment showed that a person might get a quarter to a third short-term healing. I would not explain that as a "yes".

Others can easily duplicate my expermiment. Human nature being what it is, some people so dislike an ugly reality obstructing of a lovely story, their counter arguments will always be in words, not deeds. The litmus test: Desulfation remains a struggling industry. Something is not right. There is no conspiracy.

If you want batteries to last longer, deal with them, help them while they are still functional, do not fuss over them after they "signed off". We do not feed medication to dead people. Why do it to batteries? The experiment is explained on "CAN BATTERIES BE BROUGHT BACK". 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) paired with a 3 day trickle charge assisted my truck battery retain a much better charge.

The battery carried out 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 helped; the 3 days additional drip charge assisted; the Epsom salts satisfied your belief - how to recondition a wore out battery.

ALL the so-called treatments incl epson, alum, cadmium, etc, etc, etc ad infinitum do NOTHING!!! But typically damage!! What numerous posters like to think is that THEIR!!! treatment made a distinction!! BUT ignore all the other specifications of battery action incl temp, humidity etc in their effort to understand a complex subject!! (recondition old battery). The bare truth is that all automotive charge systems do not fully charge the l/a starter batt- however only around 14v- for a number of various factors.

Bevan - Where does the acid that raised your SG originated from? John- just returned on line after week after changing ISP!!! The increased sg is because of the dollop in the 15 ml included of Inox Mx2 to each cell! IT certainly is NOT due to reducing sulfation & thus raising sg!. materials needed to recondition car battery.
