napa 8000 series battery bci no u1 300 a

An older battery may short out from all the junk at the bottom, it just depends. Only general information is disclosed for enthusiastic people. If one of the cells has low electrolyte density it runs the risk of sulfating and essetuialy killing the battery. Alice, I think you’re pointing out something that everyone knows. Of course, there are other physiochemical process also at play however they are minor in comparison (relatively speaking). Lead sulfate is almost totally insoluble in battery acid. “Cousin John” has been so helpful and insightful, it’s been a real delight following this conversation! Bertie : 1) I have a generator which starts via a 12v closed cell lead-acid battery. Right at the end the voltage rises. If it is not, the battery will likely eventually end up being overcharged or undercharged. 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. I have done this kind of thing myself. Sometimes, what we have observed is that they enhance plate shedding which leads to plate shorting and within months you tend to observe a huge capacity loss. It is often suggested that the poor conductivity of lead sulfate crystals prevents larger crystals from being absorbed. Soon after I bought a diesel generator (with advanced voltage regulation) as back up. John Fetter= The only problem with electroplating with cadmium is “Cadmium is subject to the spontaneous growth of Cadmium whiskers. Sufation crystals growing beyond a reversible size is a wonderful story. As it melted again the fresher water from the ice crystals may have stratified at the top of the electrolyte. A solar MPPT will probably typically take the batteries up to 58.4V, day after day, on bright days. john, as discussed before….why do heavily aged lead acid battery ‘positive’ plates turn a darkish black color, when the suspect culprit (Lead sulfate - hardeneing) is a whitish crystal? I have not been able to find one. They assume the other guy knows what he is talking about. a'pexiブランドのオリジナル自動車用パーツメーカー。マフラー、電子パーツ、ダンパー・ インテークなどを企画・開発・製造・販売。本社:東京都八王子市. Cycle your batteries according to demand. While bulk/absorption/float charging is nice, don’t get too caught up in minor details. Meaning, I am testing Li-ion derivative as we speak and this frequency will be different for many reasons….including whether it has a solid or liquid electrolyte. Please stop with the “car battery does’t charge at idle engine speed” thing. However, they are not recommended because they tend to create soft shorts that lead to premature capacity loss. 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. Again. The authors proposed a form of pulsing that superimposes a train of optimum duration, high voltage charging-current-producing pulses on the conventional charging current, to compensate for the undercharging that is being deliberately imposed on the batteries. We ultrasonically manufacture and engineer an ordered network at the electrode-electrolyte interface which eliminates these inherent ionic kinetic inefficiencies and therefore substancially minimize these adverse effects. I suspect you’ll need to add something to keep the graphene in suspension. Are these so called deep cycle batteries less prone to sulfation? This is a 90 AH battery. Vf increases with current, the Vf figure listed will usually be at maximum current throughput. I have personally tested ways of de-corroding and de-sulfating batteries. The positives do not suffer permanent sulfation. Then make money out of your IP. Second - check the voltage given by the car battery charger (alternator). Most computer power supplies are switchmode and are happy with 90 to 245 volts. What is the difference between a small crystal and a large crystal in terms of this effect? It is impossible to maintain this frequency on the required resonance among thousands of batteries by discharging an inductor into a battery. Undercharging. shawn - Of course I am not qualified. Came across a 7 yr old Harley sealed 9AH battery, can be charged up nicely and has loads of reserve capacity, but after a full charge will settle to a stable 12.1 v open circuit voltage. Those amps had to be accomplishing something. Recently, I got a new set of eight 6V deep cycle Trojan batteries (a total of 24 cells). It also seems common sense, logic and reason are lost on you john fetter as you generalize, dismiss and know so much 100%. As for Li-Ion, custom built packs are expensive because of all the externalities: small market segment, custom cases and circuitry, liability, etc. The battery is actually 3 smaller batteries all linked together, it’s 30lbs (more wight more battery life right?) Any suggestions beyond watering to the correct value and allow it to charge/discharge to exercise the plates to whatever capacity might be left is appreciated. 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. No need to go to the extra expense. I would suggest getting a multimeter/voltmeter and measuring the voltage the batteries settle to after being fully charged and subsequently left entirely disconnected for 24 hours, as well as the voltage that your charging systems are putting out to the batteries with the batteries connected and reasonably charged, as well as the voltage you allow the batteries to run down to before charging (both regularly and on irregular occasions). Clearly, it does not make sense to broad cast our frequencies all over the network. I use a conventional manual charger with mutiple taps for that. The inverter output voltage control appears to be slightly overcompensating. Anyway, check the electrolyte level and density in each cell. denise - It’s easy. I am not trying to be elusive, however, every time I turn I am being thrown a curve ball with this science. I will tomorrow be checking voltage, fluid and specific gravity. It is activation energy, and not any sort of pinging at any frequency, that drives a chemical change. Use their boolean search facility. Therefore there is something wrong with the theory. Any and all discharging creates temporary lead sulphate, some of which inevitably doesn’t make it back in to solution, and in addition to that discharging causes physical stresses within the plates which also contribute to the inevitable failure. Am interested in sharing research/findings/results/experience/reasoning, etc with you and likeminded, thanks for your own response. Enersys Newport have AGM up to 1200 cycles with high current charge in lab using similar charger. The acid level was way above the plates. I managed to get hold of a variety of unformed lead-acid batteries. f you start fully charged though, and just touch 15.3 that should be good. Raj There are many hundreds of battery manufacturers around the world. The person running your company, (qualifications such as CA & MBA), probably earns a thousand times what you earn, yet you probably know more about batteries than he does. That should be enough proof these things don’t work. (And if it stays fully charged, it will likely not freeze even at -15 which it certainly can drop to). If there should be no sunny weather for a week or so, we can still switch to grid energy - it is not very reliable here, but at least it can help to save battery power when it is available. 2) My multi-meter says the battery now has a 12.65v charge. Hoping for a reply. But I weigh 135lbs so that will help it. It appears that equalizing may have removed the interference. Thirty years ago I decided I could design and build an electric car. It took three weeks. Also, since my battery is registering 12.65v, should I still charge it (after I purchase a charger)? let cool and wait. Specifically on usability/ usefulness of de-sulfation of these chargers? It does not predict irreversibility. The battery is either being drained as it sits, or it never gets fully charged when the car is running. Here is what I’ve done: I put a not so well performing battery on AC/DC adapter which I found somewhere lying around (because my smart charger refuses to overcharge) and was overcharging it for 2-3 weeks @ 15V, 0.5-1 Amp. However, the electrochemical activity is confined to the actual surfaces of the crystals. Such technologies will lower the sulfation on a healthy battery”. Did you have any thoughts on my post above @ 12:35 on the 15th regarding charging and battery maintenance. There are small but important differences, though. How can I achieve this? I bought a used wheelchair with two 12V 18Ah batteries, It uses a 2A charger. Another case still, is that the motorcycle has a defective current-delivery system. Finnally i found what i can do with all my car battery. More additive is not better, with the most maxing out at less than 0.5 or 1.5 wt % of the electrolyte. Can of worms – [Reply] see above Battery Equalizing: Sep. 25, 2013 @ 5:07pm by John Fetter and, Sep. 29, 2013 @ 2:55pm by John Fetter, for details. rea Jerry. It is the battery temp, not the air temp that matters. Oh, they are expensive! All- thanks for the efforts on this forum. Are you now withholding information/experience/explanation to punnish me for challenging you or daring to support/discuss the desulphation with pulsers idea. 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. And so on until conduction is restored. However, I do not believe this can be achieved by tinkering with over-the-counter consumer products. It is important not to allow charging to continue because the battery will get hot and then draw more and more current. Very, very interesting, exciting even! Sulfation occurs deep inside the active mass. Does this means that battery is being overcharged? SG about 1180 corrected for temp and the battery temp 40F. And they’re not even that expensive. Charging at 15V and over for long periods can be detrimental. The positive active material is lead-dioxide. I was about to buy a few Megapulse units but will now hasten slowly after finding this website . They don’t seem to be holding a good charge. Sulfation as we know it is a problem of the past owing to advancement in battery technology and charging systems. Anti-sulfation devices were simply not that effective. Nearly one lead-acid battery per person. The battery is for a electric scooter I plan to ride every day in mountains. I have a thirty-year-old 50A thyristor controlled charger with infinitely variable voltage and infinitely variable current control. There are forums where everyone agrees with everyone else. I am guessing that extending the floating phase won’t make much odds. Judging by the sg readings I have always been able to keep the SoC of the batteries around 75% to 85%. Other factors may play a role. That’s hwo a light bulb works, why stuff gets hot, etc. In other words do I need to get a new charger? I don’t see any real difference in behavior between systems, they both include 2 axis sun trackers. It is a real pain to remove the battery from the generator. AGM is likely to be on the way out at 400 cycles. However, many appear to be absorbed in the subject to the exclusion of other important factors. Removed the sealed plugs and added a few cc of water in each cell. Commercial advice, definitely no. You don’t seem to have much control with the 3.5 on charge voltage though. Your discussion was refreshing. Shawn Kelly picked the ground. Diodes could work. A sunny day is not a sunny day is not a sunny day. Current goes back and forth. It is a few years since I was really into this stuff so forgive if seems bad explanation, but I know what I mean! These rates are affected by both the applied potential and the type and amount of grid alloying additives used. Clearly describing the PbSO4 as layer is very useful for illustrative purposes and it helps others….yes there are many different visions/studies/pictures of what it looks like….so I agree. As soon as it hits 15.3, switch off. will be back soon Heat can damage a battery. The majority of desulfation product merchants make the claim that batteries become sulfated with age. Take it easy, Oscar, these are legitimate objections! Your 60V system uses different equipment than the stuff I see. I use electronic circuits that are simple to make and monitor. Pay attention to the + sign! The rest of the time they just sit there, connected to the inverter that has a large bank of 24V capacitors on it’s input across the battery bank. I noticed when checking the SG readings that the electrolyte had turned a greyish color. Should I have continued for much longer? Batteries are a grudge buy. If you miss the image entry code, your message goes away. There are far too many theories and systems. i.e. What you want to know, everything you want to know and perhaps more than you want to know. Thanks for your response… Your old charger sure looks sweet and exactly what I’d love to have! So Jerry what’s the frequency you can think of the best? Yes, this has been difficult to explain 1) why vibrating cell discharged less energy throughout test, 2) why it cycled 3 to every 2 cycles under same voltage plateaus. Even the tiniest imperfections scatter the energy all over the place, and quickly dissipate it It is not difficult to equip alternator voltage regulators with adaptive voltage regulation. Could this method be used to know theal capacity of a battery? I still want someone to answer why significantly degraded and aged lead acid plates have a blackish tint when PbSO4 is a known whitish substance? Instead of changing batteries after 2 years I added the equalizer and got another 2 years use. however, when inverter is tuned off and its input is removed from wall power plug then tester never glows. There are relatively very few desulfation specialist business out there. I would have to agree with John, in my experience it makes no measurable difference, however regular, properly conducted equalize charging standard flooded batteries does. cycles. Not engines. brandon.crick@cadex.com, in my company we are using toyota fork lift in that 1 batery cell get damage so we send the batery for service. I was just about to comment on temperature when I read Marcus’ question on temps. All your claims are based on no proof of it. For those that caught that; you may be opening a can of worms many discard because their owners manual says: ‘Only once a year’. A motor in idle or at low speed cannot charge the battery sufficiently. Another model assumes that gel zones are formed by hydrated lead dioxide (PbO(OH)2) and act as bridging elements between the crystalline particles. I have a couple of batteries that have visible white blotches on a couple of cells due to clients loading them with water. Will only carry 6 hours of overnight load before switching to generator. You would most likely have obtained the same results if you had omitted steps 1 to 5 and the first part of 6, but simply added some extra acid and charged the battery. I can assure you that what your machine is doing, in plain English, is called charging. (Remember, never allow the Voltage to drop below this or expect the worst.) Repeat: There will be no discernible corrosion if the battery voltage of the battery on charge is allowed to rise to 15 volts and the charging is then stopped. Can a desulfator unit be used with a float charger on a good 12V lead acid battery? After changing the battery in the voltmeter the readings were normal. Incredibly, they do not appreciate the importance of voltage. 2nd Do Nehmo or john actually know how batteryvitamin actually works to save the battery. The cheapest charger I would recommend would be the Morningstar Sunsaver. The barrier is enhanced by the use of natural rubber battery separators. Seems like it should be near 13. John Fetter- I have a pretty good lab too, acquired over the years, Is there a formula or mix for the cadmium additive? Batteries on standby duty must have very pure water. Very interesting discussion though and I totally agree with John Fetter’s comments about battery failure and compacted sulphation. “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. how about hooking to a float charger when not in use? The meter will indicate which direction the current is flowing. Fill a bathtub with water. Ask him what store shelves are displaying his product?? The batteries are in the basement so basically 70F. For example, there were occasions when the batteries were not brought back up to ‘full’ charge before they started to discharge again. Your battery has shorted cells. }, {Let’s just say that the frequency is selected to optimally interact with the physiochemical process for the chemistry of interest. Lots of worthwhile inventions are never patented and kept proprietary and many others are not simply because the invention is not the inventor’s center of attention. SGs with the crap qualitative hydrometer is ‘full’ (4 balls floating). The big question is whether or not they can be “desulfated”. Just a little story to add from sunny South Africa…....many years ago we had a doggy-bone Ford Escort 1300, think it was a 1972 model. The cadmium goes back into solution. how comes batteries remain OK in water? The battery reached full state of charge but the current was high enough to keep increasing the temperature of the battery, therefore the current climbed up again. That document is also in the public domain but I’m certain you wouldn’t be interested in the link since it doesn’t fit your template. Learning the basics about batteries - sponsored by Cadex Electronics Inc. © 2021 Isidor Buchmann. Nate - If you’re happy to bring the battery inside in winter, only put it back in the generator when you need it,  it all becomes dead easy. NOTE: This is a general charging guideline and it is the responsibility of the reader/ user to ensure safe operation at all times. Simply tore them down and carefully extracted the plates. What it does tell us, however, is that Cell 1 definitely looks weak. No one can give any realistic guarantee regarding these remedies. There appear to be two components. For my part…I think I’ll now take the advice of a previous poster who admonished others to take everything here, “with a grain of salt.” After all…you’ve earned it!!
