napa 8000 series battery bci no u1 300 a

Meanwhile, I’m making quite a bit of money de-sulfating large batteries and doubling their life in most cases…and my business is growing steadily. I verified results on Air Canada Motive Power batteries that SG was restored and perfectly balanced after batteries lost more than 75% capacity. A schottky diode (properly chosen) will have a forward voltage of about 0.5 volts. Most of the concepts rely on belief, rather than technical merit. Hi, That explains why you are here. I use the RV for about 2 months a year. The battery will, no doubt, be able to start the engine but its capacity will be much reduced. “For example, in lead acid batteries, the use of graphene is envisaged as offering benefits in its high intrinsic electrical conductivity and being extremely lightweight, chemically inert and flexible yet with a large surface area”. Cadmium is slightly better. Or was it discharging stronger was there heat difference in the load? NO it went off scale. Although I tend to dismiss conspiracy theories when it comes to engineering advancements, when you stop and really think about it, is does make sense: by making a product ‘maintenance free’ you also make it ‘maintenance proof’. Very good at controlling sulfation. Because they are chemical or electrochemical in nature they are the ones that charge/discharge, giving up bond energy voltages when discharging and being formed from appropriate voltage levels that charge. US Patent Publication 2010 0021798, continuation of US Pat 7,592,094. I don’t have it but the battery looks like 3 car batteries in a series to make up a big 30lbs, 36v 12ah deep cell battery. I’m amazed about how much info is in this single thread. It won’t stop altogether just because the liquid is slightly cooler. I am using the solar system at home for providing power for a laptop which is in very frequent use, and some other appliances which can be connected directly to 12V DC, and for bridging interruptions in the power supply from the grid (which are rather frequent where I live) via a power inverter to 220V AC. Final total was adding 3 gallons to what are GC2 cells… so .5 gal a piece. In a sulfated battery, which is so heavily sulfated, beyond desulfation, is it possible his own giant battery bank into a boatyard where the same situation is undoubtedly going to occur.”, {spk: the problem with John’s test is that it does not replicate you or your friends situation. If I turn off the inverter and pull the plug then the voltage of battery seldom drops over a period of 24 hours or so. For example, there were occasions when the batteries were not brought back up to ‘full’ charge before they started to discharge again. I was discussing the method by which running the cells dry have had a negative effect on the cells when people has run the golf cart around and that bit of sloshing through movement has likely greatly affected the upper portion of the plates. That said if the batteries were never toast to begin with maybe nothing has been gained accept returning a good battery to service. Last month I tried to desulfate my 12V battery. I trialed a Power Systems desulfator that put out a clean square wave up to 20 A and up to 30 V that did little good on spiral wound AGM batteries and on large conventional flooded lead acid batteries. 1) Appearance: the brown comes from stirred-up mud, which is basically shed active material (lead oxide). To all, our newest efforts are in the area of mid-size emergency DC back up power supplies (i.e. Indeed, great story. After-the-problem-has-developed battery cures are equivalent to watering dried out plants. Whether it’s capacity was negatively effected or not… if it does the job, then that’ll be good enough. It should be called the “John Fetter Ego-Stroking Web Site.” I guarantee you…you’re not going to teach John anything he doesn’t already know…because he already knows everything there is to know. Fractionally above the onset of gassing. Clarify please. Some are in excess of 30 minutes. What becomes evident is that the majority of carbon-in-lead-acid corporations are finding it difficult to make decent progress in the unforgiving world of business. Ask him what store shelves are displaying his product?? You’re telling others to give away their secrets but give yourself the right to hang on to your own. If that was not so, there would be many successful desulfation centers out there. In other words, it sits there, appears to do nothing. however we have charged the battery now for over 20 hours and the Specific gravity went up to 1225 and the battery has warmed a little to 35degF. Can you add anything to my precarious position to as to make me more capable to defend myself against my carnivorous clients? Why are you messing around in crystal fairyland? Thank you for your advice and support in the meantime. A healthy battery on charge, even a sulfated battery on charge, after 20 hours, will measure over 15 volts. Depending on the amps, temp, and cell sizes, you may find that a warm weather bulk voltage can be your absorption voltage. I also live in California and heat is also a constant problem. Some stratification is definitely possible. I would not base any decision based on your test set up. There is plenty of excellent literature, Handbook of Batteries by David Linden; Lead-Acid Batteries by Hans Bode; Electrochemical Power Sources by Monty Barak and, of course, Storage Batteries by George Wood Vinal and so on. I had dosed the cells with cadmium. The cell is never really fully discharged. This brought me back to the old peukert effect….something was making the vibrating cell discharge harder and therefore it was giving out less energy on the first discharge and this set it up for the remainder of the test. I could zap them some more. regards, This salt is available at Kasur scientific store located near noor mahal cinema at the cost of 90 PKR/packing. I do not intend to cut open the jar… remove the separators and scrape the plates either… nor had I alluded to that from what I recall writing. Anyway, it still came with a generator and the three relay control box. I found thru google, a few website pages showing scanning electron photos of sulphated plates before and after pulsation, with the details of the trial/experiment clearly set out. The cost of lead, per pound, is $0.98. To do this with a 0.1 amp current would require ten hours for each AH, which is 500 hours. If they believe you are right, you will make a fairly large amount of money. The two systems including batteries, solar chargers and solar panels are identical and separate. Forklift batteries must be charged to at least 2.55V per cell. As for a light load causing the charger to run for a long time - the only way to find out if it is a problem would be to measure actual power consumed by the charger. Something starts the charge cycle on your charger too. There are no simple methods to measure sulfation, nor are commercial chargers available that apply a calculated overcharge to dissolve the crystals. I live in the Andean highlands where sun radiation is quite intense. that engages on a regular basis. While I do not know the battery’s natural discharge rate,  I am afraid I would need to charge it weekly—and I could miss that schedule and then have a compromised battery]. Thanks for all your working in this batteryuniversity.com, very iinformative when i read all the forum especially in this desulphation method and how to prevent. It will give you a quick idea of whether you have been reading from a stratified layer, but I suspect that you need to give the batteries a long equalizing charge regardless of stratification. my advice is to buy a cct and try it for yourself, only €20 odd. It is a document that explains something about battery pulsing with crystal clear clarity - needle-like high frequency pulses are useless.     i am from pakistan i want to know about battery terminals why the anode terminal of battery is more sulphated than the cathode the terminal Kudos to John, Jerry and Bevan for keeping this subject alive and under active research. Designed by marketing people, not engineers. So what is going on if desulfation pulse charge is a red herring? I put an external Balmar type regulator on my alternator. The industry eventually figured out what ingredient in the wood had been keeping their batteries working and managed to replicate it. Only last week I discovered that a large commercial NAPA charger does the same thing. Surely one of you could have said, “look inside, that will explain it”, in the first place?. Step 2. This phenomenon influences the energetic performance of lead-acid battery positive plates. Thanks again John. Just a correction first on SG readings - I entered an incorrect value. They are gradually released from the grid by corrosion, and permeate the active material by dissolution and diffusion. But ours do no such thing. I would be appreciate much your opinion on the questions as I see you very experienced on the subject. I did not realize that these would be so hard to find. If you want to charge a battery very quickly, two things need to be taken into account. - After a full charge, I suppose it would also be possible to maintain the battery by not discharging it to under 50%, so it could be fully charged again on a single sunny day. Tony E. - It appears there may be two ways to look at the situation. and 50 centigrade for few weeks, Bob L. Update - I pulled one of the batteries out of the matrix and baked it for an hour at 16.2V. That is the battery business dynamic. And so on. This was a proper industry once. Battery voltage is not a reliable indicator of a battery’s ability to deliver starting current. Sulfation affects the positives AS WELL AS the negatives. I would suggest that implying that charging extends the life of a battery is analogous to suggesting that eating extends the lives of animals. 3 cycles) did discharge 1/3 less energy through out 8000 minute test than control cell (i.e. When specimens of pure lead and a 5% antimony alloy were periodically oxidized and reduced, lead oxide layers were observed with different structures: 1. Don’t let this carry on too long. Do you charge the batteries upon receipt? the measurements would seem to indicate a slight problem with cell number one, don’t you think? Neil - Let me try this again. The discussion in the past months on this site has been nothing short of astonishing. Is either correct? shawn - Why are you here? Considering the SGs looked good, as rough as the hydrometer I was using showed, and the ICVs resting were almost dead on the same gives me some hope it’ll be good enough to keep going awhile longer with acceptable capacity. Bob B It will allow to reduce sulfation increasing conductivity in the negative plate. The important thing to remember is to keep current and temperature low to avoid rapid internal corrosion (now would be a great time for you to do it, it seems). Flooding works by aggressive acid boiling and 14.2V 5 yr benign life is what cars seem to use now. Would you like to provide the details behind the twist, the addiction, the can of worms and the owners manual? Maybe it would be time to get back to a sheet design, where reactions are limited only to the surface, rather than the current powder/sponge design. The batteries will be equalized. That should be enough proof these things don’t work. I have tested these big pulse units. If the crystals haven’t expanded and damaged the plates, they can be pulsed back into solution. The cadmium forms dendrites that act as seed connectors. The battery is actually 3 smaller batteries all linked together, it’s 30lbs (more wight more battery life right?) I don’t need indefinite, but if I can run a month at under 50% state of charge without long term damage, that would cover most if not all solar installations as I can force a full charge on a regular basis, just not that regular. Marcus - My take on your experience is that your battery was simply discharged. CTEK absolutely works here. Generally people who are doing small solar are doing it for “low maintenance”, Is it going to be practical for you to disconnect the main charge controller, disconnect the panel, connect the panel up to something that limits current, reconnect, ensure you only run it for a set period of time ..... of course doing that when the battery is already fully charged (which is not easy to determine) and when you have full sun, etc? Capacity and current capability derived from voltage is a science, and difficult to get right. People are permitted by law to patent ideas they do not understand. What are you trying to explain? constant stirring), so that the crystals formed are more uniform and can therefore be dissolved back into solution more evenly, and possibly avoid the formation of larger crystals which are harder to dissolve - or if these larger crystals are semi-permanent they may combine with other leftover “crap” which results in something with even lower solubility? I attach standard Schumacher 30amp chargers (Walmart) for reconditioning them. I’ve begun using one of the more well-know powdered chemical additives for de-sulfation. I’ll check load voltages under heavy use and SGs during discharge… along with ICVs during recharge to see if one cell is very poor and dragging the rest down, or for the ICV peaking that occurs on a problem cell. After one hour readings were like this( all cables from battery were removed as well as inverter); cell no 1= 1.92V, cellno2= 3.99V, cell no3=6.06, cell no 4=8.13, cell no 5=10.19V, cell no 6= 12.26V. Perhaps the batteries needed a different plate or grid chemistry. Do not speed charge. Once again, any tips are welcome and will be tried enthusiastically! We take care of it at the manufacturing level. Without knowing anything else about your customer’s issues, I’d say that if all of the component batteries hold relatively identical resting voltages, then you should find something else to worry about. (PbO2) on account of its strong adsorption and leads to a fine grain structure of the positive active material. Am I being too optimistic? The technology simply isn’t up to the task. If you want to know if a lead-acid battery is fully charged or not, simply put it on a C/50 charge and watch the voltage. Give it a good charge. He spoke of 3.26 MHz as the resonant frequency of sulfur crystals (?) Regarding these numerous desulfators out there, has anyone tried this German desulfator named AccuCare that supposedly contains microorganisms that basically eat sulfate off the plates? Where is all the H2SO4 going? I mentioned to clarify in case it was a typo (12.2V took me by surprise!). BU-410: Charging at High and Low Temperatures, BU-413a: How to Store Renewable Energy in a Battery. Can anyone explain why the battery charges normally, seems to have decent capacity, but the electrolite SG is too low. On most boats this is fairly difficult. I plan to continue using this particular product!! The Noco seems to have a warm/cold setting, but unless it actively detects temperature and compensates (not as easy as it sounds as batteries have thermal mass too), then the cold setting is only a bit better than no setting depending on how cold the battery is. On September 1, 2012 at 5:31pm The cells are gently fizzing. Anyone care to shed some light? You can scroll back and see that I never really submitted much information. John Fetter: In science and tech, no one can fully be a master of any technology. The Europeans spend huge sums of money on highly purified water for industrial motive power. The barrier does not impede the underlying electrochemical charge-discharge battery reactions. It is not a symptom of aging. Gali’s patent is reasonably credible, although not strong. The battery terminal voltage is allowed to rise to between 2.50 and 2.66V/cell (15 and 16V on a 12V mono block) for about 24 hours.”. If anyone finds out or knows, I’m all ears (or eyes) (john?) Are you a troll or are you just looking to scam people with some mystery snake oil? Hydrometer readings. I think you will agree there is no useful advantage to be gained by shouting out its identity. 2) My multi-meter says the battery now has a 12.65v charge. Be careful, the more you learn about batteries, the more addicted you will become, for more knowledge. Frequency Range 50Hz / 60Hz Re who has what patents, a quickie search I found no patents by John since 1975, and one, on power recovery from tissue, (or something like that), by Shawn. I have tried it. There is no way that an 8D battery can give you 15.1V and at a specific gravity of 1175 you should see a voltage closer to 12.1V, if that. I am certainly suspicious of the accuracy of the battery indicator gauge and intend to fit a more accurate one. I expect this may be the problem as maybe I don’t get such a high current at 14.5V-14.8V. In a model that considers the active material as an aggregate of spheres (“Kugelhmfen”) it is explained by a gradual increase in the ohmic resistance, mainly in the connecting region of the individual particles of the active material. Continue the process is nevertheless called charging 13.6 volts over 3A, 14.4V and transition float., light or heavy discharge, as the battery be deceptive, especially over-charging!
