Could the 3rd option also be correct if there was “INcreases”? ? historiquement, sur les produits Chrysler les batteries duraient 3 ans (3 hivers) et la batterie pouvait faire un autre 2 hivers sur un véhicule GM Looking for new charger, Original was a simple unregulated transformer type (Original Fitting) I now appreciate from your articles and others that an intelligent 3 stage type charger is required. You should test them individually to know. now can you suggest me how much backing soda and epsom salt is needed to clean and salpate my battery respectively…. With 2 batteries in parallel you get a 15Ah battery pack. Is there a limit as to how much I should allow the alternator to charge in this way? I keep them above 11V. From aspiring to be an astronaut, teacher and video game maker, to seeing the oceans and discovering new fish, to “making music that brings people together,” to working for world peace, there was no shortage of big dreams. So for a medium sized 12V with 40AH capacity that equates to ~5-6amps. Range with 3s lithium 3,000mAH is about 45 mins driving 3/4 mile, paved. Kind regards, Willem Ferguson. 15V is very high on a 12V battery It may be thr reason for the batteries to be bloated In the name of God There exist de-sulfatation tools that give charging pulses (Amazon) but be careful; this is not a car battery we are talking about. When looking to describe our electrified power applications, many adjectives come to mind, including durable, reliable, safe, and ...beautiful? - the battery won’t charge with 12V, it will need more, like 13.8V. (2.4*6)+((25-30)*0.004*6)=14.4+(-0.12)=14.28V, 12V battery, ambient temperature is 15 degrees C. But SLA/ AGM/ VRLA are emitting a very small amount of gases due to their construction. With the engine shut off, the voltage will be between 12 and 13V. For this i do not want to use inverter or ups because they spent a lot of power instend of antenas itselfs . Watch the current. Normally they tend to equalize during the charge, but one battery (with the highest voltage) could have a hard time and can even get damaged before it gets “equal” to the other. So if you have e.g. I recall from AGM docs that an AGM battery will accept high charge rates. totally not suitable for you therefore the charger puts in the rest of the absorptiontime 30A into the battery. I started fan and it is blowing straight to batteries. The 2000cc will consume more at full power, but might consume less at low power/cruise speed. Andre. If I can’t get the low one up far enough, should I discharge the high one to match? 1. It also has a HIGH mode where it will put 14.4 V on the battery. When you charge the batteries what voltage do they reach? Is that about right? There is some limitation from the copper wiring, of course. Is it already charged during manufacturing? Or it is OK as long as during one of the next charges (let’s say after first use) the charge goes to 100% and then is stored (and checked every month)? For the purpose I am using the product for is to keep batteries fully charged and maintained. 1) I have tried to discharge the battery with 5 volt 18 w bulb and 12v 9w bulb in different time .but it does not work properly. Les autos américaines, GM et Chrysler, les batteries durent 3 à 5 ans gros max How much capacity may have it lost? Response to Bob k Even this seems too high a voltage, but on measuring the output it is between 19v and 20v. I found 2 of the charged batteries draw a couple hundred mA, but the third one draws way more and it increases while charging. As leaders in battery, fuel cell, and hydrogen-production technologies, we’re steering the way to a brighter tomorrow. Keith Taylor. Is this why it fails to keep my less than one year old battery charged? The open-circuit voltage was 12.0 V. After I loaded it with a high power resistor, causing it to produce 500 ma for a couple of minutes, the OCV went down to 11:92 V.  Under load it drops to 11:55. Good luck! Â, Ultimately, like most students taking a test, we want to pass. TRYPTOPHAN This amino acid is essential in the production of serotonin and melatonin. 2) how long it actually take to charge a 6 volt 4.5 Ah battery with full wave center tap circuit and the other information given above??? Thanks in Advance You talk about connecting a resistor and measuring the current, so I assume you know at least something about electronics. I was hoping to find the positive plates to be similar to their negative brothers, I was going to melt the down and re cast the positive plates, weld them back to the spreader bars , put it back together and hey presto, something resembling the performance of a new battery. My Battery size is 19 * 7.5 * 15 (length * width * hight) all measurement in inches… now can you tell me how much backing soda and epsom salt is needed to clean and sulpate my battery respectively…. What does the 5hr mean? That being said, NCA/NCM in the 18650-format cells have a much better selection of choices, and provide high power and long range in a small package that is affordable, due to mass-production. Je n’ai pas de problème encore avec la batterie mais je les vois s’en venir. Excessive charging causes electrolysis, which emits flammable gas : hydrogen + oxygen. I am sorry to say that I have the power to get my battery back to me. intelligent chargers are not that intelligent and are likely to misbehave under camper load If you have a multimeter capable of reading DC current, you can put it in series too (between + of charger and + of battery) to monitor the charge current. I might hook the PWM and run my LED lighting or USB charge ports through its load port. It will become lower after a while. green charging, bike battery ko ager ham kachchi plat me battery kar baad me charg kara to kiya rigelt milega, during charging battery why use battery for dc fans, I cannot understand your question Why not use an RC method to clean off the sulfation? The pH scale is a little backwards, at least in my opinion. I have not checked the voltage on each cell . Thanks. To Mb Mubin Hi! It all depends. From the limited time they run the house they are not fully charged. The low cells voltage would not come up even using the ‘Equalisation’ setting on the charger. Or is the voltage 5.5V, and when you connect a charger the voltage goes up but no current flows? - Gassing within the battery DEcreases when nearing full charge and it will be necessary to reduce the charging current to a low finishing rate. To Steve F There is no one-size-fits-all approach to batteries, rather, it is about providing the right electric solution to meet the needs of the application. That gives you the number of batteries you should put in parallel. I’m afraid it is dead. cummins.com, Spot the Difference: Lithium Ion Versus Lead Acid Battery Electric Technology, Driving forward: electric school buses inspire art, Powered by Cummins: XCMG Electric Excavator Makes its Beautiful Debut, Trusted because it's tested: Cummins-powered GILLIG Battery Electric Bus, The Future of Fleets: The four keys to electrification – Part 4, when Cummins and GILLIG announced the partnership, Big Blue Bus announced that they will be purchasing 18 additional electric buses, The Future of Fleets: The four keys to electrification – Part 3, The Future of Fleets: The four keys to electrification - Part 2, The Future of Fleets: The four keys to electrification - Part 1, Cummins Corporate Website - Pусский. juste check occasionnaly that the battery voltage does not exceed 13.8V. E.g. ils font + de domages que de bien But can it be charged safely?? I am heading towards the shortest day of the year with many cloudy days but have managed to keep the sg reading at or slightly above 75 % SOC. Most battery chargers give an option of 2, 6, 10 and even 20 amps. Hi ! This paste is darker in colour then that in the negative plates. Often operating on work sites in densely populated towns and cities around the globe, construction equipment must meet stringent emissions requirements and keep noise and disruption to a minimum while getting the job done. The batteries are in a different country at the moment, so an exact response is difficult I know there’s bulk, absorption and float voltage, but I don’t know any reliable website with reliable and detailed descriptions about them. During last fishing season, I was recharging them every week with an old 5A manual charger, watching the gauge and disconnecting when it approached 0. if no why ? your assumption is correct, but keep some details into account: Charging  At rest I would expect something like 12.6 though that will change a little depending on battery chemistry. In other words, if you were to drive the same distance using each type of batteries in an identical vehicle, the lead acid battery could take up to 10 times the volume that the lithium ion would, and it’s also heavier. Â, When it comes to battery electric vehicles, there are four keys to adoption within the commercial vehicle sector. Again, sorry if this is incredibly incomplete.Thank you. BU-802a: How does Rising Internal Resistance affect Performance? Can you explain how ambient temperature are playing role fir battery voltage. The only thing you could try is refilling the cells with distilled water. Learning the basics about batteries - sponsored by Cadex Electronics Inc. © 2021 Isidor Buchmann. Again, it is hard to tell which one it is. BU-304: Why are Protection Circuits Needed? Should I take the bank apart and try each cell separately? Also tell us to what voltage you are discharging. I want to charge a Century PS612 6V 1.2 Ah sealed battery. How can I fix it so I can still use it without getting hot wires? But chances are that the charge current is quite low anyway, since the batteries are for backup system. incroyable A 12V lead battery should never go below let’s say 10V. The yellow light showing when its fully charged. to GM: With flooded plates you can always check acid SG. To get Ah instead of kWh, you need to go via the watts calculation above, since your primary current (at 240V) is way lower than your secondary (at 14V). A lot depends on peak discharge currents. Thank you for your feedback. Amazon.com : Soil pH Meter, 3-in-1 Soil Test Kit For Moisture, Light & pH, A Must Have For Home And Garden, Lawn, Farm, Plants, Herbs & Gardening Tools, Indoor/Outdoors Plant Care Soil Tester (No Battery Needed) : Garden & Outdoor I left it charged for around five hours but I turn it off at night, I resume the charge this morning. What the hell are you talking about paolo??? To Niska I run various accessories off the auxiliary battery including an inverter for 120 volt devices. Does it mean that somehow the 12.20V has a worse battery and I should change it first. Read on to learn more. Cost  Now you put them in series again, use them, and charge them with 27.6V. Reading this, you see there is also a time factor. We have a fire alarm panel that has two 12v, 12ah batteries. If you “leave” it to 11.3V it is not good for the battery. i just want to ask and my question is what does 2v,600ah mean on the battery. There is a rule-of-thumb saying that the remaining capacity is the voltage above 12 x 100. Hi, I have 3 12V SLA batteries wired in series and found that the group wouldn’t charge. How many Ah, voltage? Problem is:- My charge controller default setting boost and float voltages are 14.6V and 13.6V respectively in SMF mode. The future looks bright when we unleash the power to dream big and embrace the opportunity that each tomorrow brings. I tried to adjusted voltage during charging on PCB charger regulator via trimmer but nothing happening. The lead appears clean and does not appear to of deteriorated. Weight of the electric car has also been a recurring design difficulty in them. Red &Yellow;. 120=0.833Amps) = 144 Ohms lightbulb most of your answers can be found at the beginning of this blog Good luck! the spreader bar and terminal post are heavily covered with flaky pastry, presumably shed lead. I am so glad that I have found this comment section. The formula for that, if I’m not mistaken, is: A 200 watt amplifier is probably 50% efficient so you are really pulling bursts of 400W +. Better avoid to get down to 11.3V… “We’ve had LSD,” John Lennon told George Harrison.. The cells are joined via welded connectors with the positive post at some time being changed to a small self-tapping screw holding down the high current draw cable ! A powertrain that can operate efficiently, but can only do so empty, is of no value to a community looking to transport people all day, every day. A small UPS is very inexpensive and you can add what ever battery size you wish. to Dr. Kalinba: Maximum peak current draw from my 120Ah leisure battery is 15A for perhaps 30 seconds, and under normal circumstance continuous discharge is kept well below 6 A. and even when charging the current draw by any load comes from the battery not the charger! What you never want to do is split water into gas. Â, What do sand bags, mountains, a drone and a film crew all have in common? After 5 days they now all read 2.2 volts. Xealgar, I need a 12v 40Ah/5hr. Will I be able to avoid sulfation? Range with the stock lead acid is about 1 hour driving maybe 1 mile paved. The battery pack consists of 24 cells with 6 in each bank, so 4 banks of 6 cells. BU-201: How does the Lead Acid Battery Work? But then again, with the small current load, your generator voltage might be higher. @Natasha:  Yes, it’s very safe if you charge the batteries in a vented area, not in the kitchen and the charger stops when voltage on 12V battery do not exceed 14…14.5V. When you charge with C/10, each 18AH battery should get 1.8 Amp. Does the paste make a huge difference? Here is my problem: Initially the discharge/charge cycle took some 9h, pushing some 0.7 Ah through the battery. thank u, To Shaila to Ben: your question is not too clear Comparing the two chemistries side-by-side, lithium ion achieves an energy density of 125-600+ Wh/L versus 50-90 Wh/L for lead acid batteries. But a 2 amp or even 3 amp peak for a few seconds won’t do harm. I have a 350AH flooded cell that I charge at 10 A. I have concerne in regard to the state of charge and condition of the 12 V battery in my car. Add a temperature compensation probe to what ever charge controller is in use. What type of batteries exactly? Is that to be expected? The voltage then drop again after another few minutes reducing current, my charger switch back to CC 4.5A charging while the voltage drop until 14.1V. If not, a step-up converter will do the trick and load your battery with a decent current. Good luck! First trip <2km battery near flat. Current will be highest when just connected, and will slowly drop. A sealed battery should be charged now and then with 14.3 ... 14.5V until it is full, to avoid sulfatation. Ricardo Les alternateurs, starter de BMW, AUDI et Mercedes, 1500$ min! sorry for the delay This suggests the battery is becoming less efficient since the discharge time has decreased and the charge time has also decreased, and that what I am doing is not good for the battery. I would think (and don’t trust my thinking) that 1/4 or 1/5 C is a reasonable limit. it has not been cycled, totally new, after reading your guidelines about charging , my charger has 600mA and 150mA and 180mA output charging ports(analog charger),  what is the recommended charging current , (0.1C is 720mA)  but the charger has only 600mA max ) can I charge in that port (150mA) for 48hours because theresnt a Pb sign) how many cycles the battery will reach top performance and how to maintain? I always had a dream to start a Lead Acid Battery Manufacturing Plant in India. this is quit long so apologies in advance Your answer is highly appreciated… thank so much…. Dear sir the red light showing when its charging. Nickel is also called Dime (recommended by englishcreamcakes) and Quarter (recommended by … Best regards, "Education provides the platform for success”, said Brian Wilson, general manager of electrified components at Cummins. Problem is that the voltage changes a lot. Andre. @Napa: Not suitable for charging at high room temperatures, causing severe overcharge, Watering is the single most important step in maintaining a flooded lead acid battery; a requirement that is all too often neglected. The voltage compensation is calculated like this: (2.4*(number of cells))+((difference between 25°C and current ambient temperature)*0.004*(number of cells)) Getting it right means having conversations across stakeholders in industry and policy, as well as end-users, to deeply understand the issues and ensure successful roll-out.Â, To learn more, please visit our ‘Future of Fleets’ whitepaper, which looks at the four keys to electrification, with insights from a range of industry experts including Addison Lee, dg:cities and Nuvve.
