That is pretty typical. The silliest thing you can do is to put all type of sulfates into batteries in the hope of solving an issue. Urban myth will never ever pass away. Pencil lead can consist of some unusual substances in addition to carbon (materials needed to recondition car battery). There are plenty of carbon powder manufacturers. 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 couple of 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 injury in spiral pattern.
To acquire Cadmium Sulphate, boil up some electrolyte- drop cadmium in- will bubble up & emit hazardous fumes- do outside -do not breathe vapours!!! When cadmium is completely liquified( & often the electrolyte cadmium mix is a charming green, depending on quality of cadmium from cell maker!)- task done! Got ta state- the mix I have actually added to batt cells does not appear to help! In fact- I got ta say the ONLY thing I utilized that worked was INOX MX2( in 1 batt so far- I will get some more MX2 &try; & shot; in other batts to validate yes or no! Apart from that, the other thing is that the batt itself should be only lightly sulfated).
Still it is excellent at identifying o/c cell/s in batt- pulses go up higher with degree of o/c! have actually seen 1250 volts! Cut open, & broke down pos grid! in 1 cell-others nearly so!. what is in battery reconditioning solution. Bevan - I would suggest improving the cadmium by making the cadmium you recovered from the NiCds the positive in an electroplating cell.
Use a tin wire or solder wire unfavorable. Source of power 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 across the electroplating cell will be under 0. how to recondition a battery at home. 5V. The green you describe would be nickel contamination.
Bevan - That's creative! Why didn't I consider that before? I will try it. John - You're one clever gentleman, thanks for the info. Bevan - I think I might have at long last managed to determine what cadmium sulfate does. It definitely electroplates out onto the negative grid metal when the battery is intentionally pushed into regulated overcharge.
This helps the lead sulfate nearest the grids to become active 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 procedure seems to have a limitation. battery recondition. 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.
Adding gradually more simply creates dendrites and causes shorts. The descriptions given by desulation merchants that insoluble sulfation undoubtedly coats the plates when batteries are used which their treatment strips it away is pure fantasy. The sulfate stays right where it is. It is converted. While both positive and negative plates can become sulfated, the favorable sulfation simply reverses when the battery is charged.
John - If I understand you correctly, did you meant all the cadmium does is electroplating itself on the unfavorable grid?If so, wouldn't just copper is excellent enough? Afdhal- it is simply John's theory- however i would state cadmium does not just 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 potential of -0. 1262V. The electrochemical potential 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 negative 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 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 take place.
Bevan - It is not a theory. I ran the experiments. Constructed lead-acid cells in glass jars. I observed and measured (recondition battery guide). 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 FACT- your findings MUST be duplicated by other like minded persons- can't see that taking place right now- still, there is hope.
Bevan - I personally could not care less what people suggest about sulfation. I ran an experiment created to respond to yes or no, whether batteries can be desulfated. My experiment showed that one may get a quarter to a third short-term healing. I would not explain that as a "yes".
Others can quickly repeat my expermiment. Human nature being what it is, some people so dislike an ugly truth obstructing of a lovely story, their counter arguments will constantly be in words, not deeds. The litmus test: Desulfation remains a struggling industry. Something is wrong. There is no conspiracy.
If you desire batteries to last longer, deal with them, assist them while they are still serviceable, do not 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, anybody can state what they desire about sulfation or desulfation, but adding Epsom salt (option= 8 teaspoonfuls Epsom salts liquified in 1 pint distilled water) combined with a 3 day drip charge helped my truck battery retain a better charge.
The battery performed 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 portion of the 1 pint of water that you managed to take into the battery helped; the 3 days extra trickle charge assisted; the Epsom salts satisfied your belief - battery reconditioning equipment.
ALL the so-called remedies incl epson, alum, cadmium, etc, etc, etc advertisement infinitum do NOTHING!!! But generally damage!! What numerous posters like to think is that THEIR!!! treatment made a difference!! BUT overlook all the other parameters of battery response incl temp, humidity etc in their attempt to understand a complicated subject!! (reconditioning car battery). The bare fact is that all automobile charge systems do not fully charge the l/a starter batt- but only around 14v- for several various reasons.
Bevan - Where does the acid that raised your SG come from? John- just 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 definitely is NOT due to lowering sulfation & hence raising sg!. how to recondition a dead car battery.
