4. Or will I need to charge them one at a time. I measured an open circuit voltage of 30 VDC coming from the charger. i use them for my little audio amp as it is 12v. I would welcome some guidance please as the source of the house alarm kit suggests charging at 7.5V 500mA whereas the shop selling me the charger says charge at 6V and that is what the charger is doing (hopefully). Hi, Sounds like you had one battery fail shorted and the other batteries overcharge the heck out of the one stack with the shorted battery. Lead-acid batteries are the dominant market for lead. The voltage prior to connecting the charger was 12.42V. See Youtube movie: "Charging a Car Battery with a Solar Panel and Charge Controller" Best regards, Andre. The self-discharge and capacity losses of the RVC-based lead-acid cell have been investigated at different storage times (0, 1.5, 3, 6, and 12months). the one i have is a commercial one and inside theres just a transformer a retifier and an ammater.the only protection it has is a thermal switch on the tranformer.Personally i find this a bit dangerous as it does not cut the chaging when the battery emf is reached,(13.8-14.5V).I already 've wired a couple of test circuits one of which used two thyrsistors,one for monitoring the battery votage andthe other is the switch.the problem i'm find with most of the circuits is that as that when i apply the charging, the voltage goes up cos the battery acts like the capacitor and this goes above the sensing voltage set ie 13.8v.would current limit solve this problem?thank you, Dear Sir/Madam I use a 100N sealed batterry (12V) in my home powering three light blbs of 7watts each but I only use soler charging only and an electric charger as a backup when sunshine is not surfficient. Emergency lighting, is used only a few cycles in its life as oppose to a laptop or cellphone battery I did briefly look for a DC-DC battery charger I need more details Will random fluctuations in voltage/current hurt the battery or create an unsafe situation? The 7 ah will used up first, so u won't have 24 volt. And I found a sine wave output invert is required for many loads. the battery shows a max of 14.24v at a particular stage of charging process . If I give not more than 1.8V will the charging current decrease to the minimum of Stage 2 without any regulation or not? Thanks! ie what is the output voltage: 6, 12, 24, 48 etc. Is this normal for a recovering battery or it's almost dead? A larger load should reset the charger state. If my understanding is up to speed the negative aide of the battery does not degrade ? You probably need to get me more info about your test. How many Ah, voltage? Again, due to the ultra low resistance AGM is the only way to go. how long will it take to charge the battery fully. But i heard from battery service engineer it can be charge while another 12 V battery takes in parallel That means if i connect another battery 12V, total battery voltage will be 9V.. is it ok for charging the same.. Hi Bob, I believe you are responding to my post, maybe not as I have not read all post's earlier than mine. I'm looking to do similar to you bob and to measure the SOC in charging, discharging and idle states on a battery cart. You need to drive to higher volts to push in the last remaining capacity. NOW A DAYS THE BACKUP OF THE BATTERYS ARE JUST FOR 2 HOUR WITH ONE FAN RUNNING WHAT SHOULD I DO. Will it damage the battery if I charge at this rate up to 70 or 80% (keeping Voltage below 7.2V), and then continue charging at a more moderate rate? Hy, I have a car battery rated 12 V, how do I know the level of how charged is ? Lawrence. That gives you the number of batteries you should put in parallel. Hi Pavan, If your charger puts the required topping voltage on the battery terminals, and your current has dropped to 10050mA, I'd say it is full. Some time ago generator died on my old diesel truck, so I have to recharge the two SLI batteries manually (I'll install an alternator and scrap the stupid generator). The faster you discharge a battery the lower it's C. It is important to understand the at which discharge rate the AH capacity is based on. Elsevier, Amsterdam, Surface Area of Duocel Foam, ERG Aerospace Corp. http://ergaerospace.com/technical-data/surface-area-of-duocel-foam/ Accessed 31 Jan 2018, Czerwiski A, Obrbowski S, Kotowski J, Rogulski Z, Skowroski JM, Bajsert M, Przystaowski M, Buczkowska-Biniecka M, Jankowska E, Baraniak M, Rotnicki J, Kopczyk M (2010) Electrochemical behavior of negative electrode of lead-acid cells based on reticulated vitreous carbon carrier. 5C rise is considered the limit of a healthy battery, I have seen much more on old batteries (hot spots on the outer casing) very hot spot Of course an internal sensor is preferable, but life is life Use a thermocouple probe, there is some compound, very similar to chewing gum where you stick the temperature sensing wire close to the battery surface and wait 3~5 minutes for the sensor to stabilize Concerning your charger, it is wiser to use a higher voltage with a series resistor the output current is much more stable (due to line voltage variations, battery voltage etc. multimeter set for 10A full scale) in series with the battery and check if the current is not above 5A. Even the wiring schematic of what not to do looks likes heaven compared to what the guy did. The ones in the unit now are a little over a year old. Anyways, Thanks once again. The manufacturer recommended a 15 hour initial charge, which we did. Y a des mystres dans les batteries mme que la technologie date de plus de 100and Depuis plusieurs annes jai de Mercedes. Yes, there are limits to charging rates but that depends on the type of battery. BU-802c: How Low can a Battery be Discharged? The material on Battery University is based on the indispensable new 4th edition of "Batteries in a Portable World - A Handbook on Rechargeable Batteries for Non-Engineers" which is available for order through Amazon.com. I am charging with a lab power supply set at 14.4 volts and have gotten current down to ~60 mA. Pull down: http://www.sunduino.com/updates/SunD_Demos.zip as it has a lot of hardware and software info. Full charge is defined with the SG and battery voltage stop going up. Hope for your reply soon. Is it safe to charge this continuously from the truck's alternator, or should I return it for a standard wet lead/acid battery? plug-it in, try-it out, if you have a meter, check if come current is coming out (BE CAREFULL! This offers several advantages to lead acid systems, including faster charging and instant high load currents on demand. I have been using a charger to charge a SLA Battery 12v 21ah,i have put the charger through a charger tester to show the v and ah of the charging cycle,should the voltage have peaks /spikes during charging? Thank you for any commects you can offer. I don't know of any manufacturer that has tested their batteries under the conditions you're wanting including the LiFePO4 ones. Thanks in advance for your help. In my opinion, if possible, charge them both separately to the exact same state. It would be like a one way bering on a regular bicycle If you were to ask at what speed is all this going to take place This where the engineering comes into play, mechanical, electrical, electronicsand yes it is very complex I have an electric bicycle (that I am very fond of) to illustrate how complex. Optimum values would be most helpful. In Fig. Is it a constant voltage Charger ? it depends on the machine. Check out some multi phase chargers (Bulk, Taper and Trickle ) but be prepared to spend more. Any document or information could be helpful for me. I guess it is best to simply install the new battery into your fan, and then charge it. (and ensure this is true where possible) And how would I compoensate for say self discharge and temperature and their effect on the amount of charge the battery is able to provide or recieve? An Xbox is far from ideal load, so let's say you can deliver 400 watts for 5 minutes. Strong pulsing punches through, restoring battery ampere-hours dramatically. Its voltage output 13.8V, 5amps? This usually happens if battery is kept discharged for a while and then when charged cells short out because of hydration. But when the voltage is 13.8V, the current has already dropped to 200mA and not much charge is added anymore; the battery is then almost full. This gives you the chance to prevent over charge or over discharge with a series switch. Can I charge my battery using the lighter socket in my car? Will this be ok to use? Andre, Hello Andr, Please could you answer to my question from November 11, 2015 at 11:23am just above ? I will work over it . I would be very curious as to the voltage drop. As per my battery capacity it should run almost 7 to 8 hours. Hydrogen gas generated during charging is explosive. Is Li-ion the Solution for the Electric Vehicle? Say it is a 7Ah battery and you decide to limit to 1A. Best regards, Andre, can you please tell me, what is the maximum level of discharging the Battery in stand by mode, Hi David, like the explanation on top of this page says, you will need a topping charge voltage of approx 14.4V (or slightly higher if you wish). (1)Pls i have a brandnew Shoto 12v 100AH VRLA (6-fmx-100A Model) battery i want to use with an inverter for backup during black outs. How long would I need to keep the unit plugged in for it to recharge? Charging at these lower voltages reduces gassing but takes a LONG time to reach full charge. This allows some recombination of the gases generated during charge. ), or if it's symptomatic of having damaged the plates of the batteries, or some other phenomenon? Cells used during our newest experiments have capacities up to ca. It's got me wondering now. It wont do any harm if you charge it first. Almost all of the battery acid has drained out of it. 2A as max charge current. Tap water may be acceptable in some regions. Thanks in advance for any advice, John Riley, Perth, Western Australia. Can I use Lead Asid battery on my UPS? Dead too. 3) Which of the following option is better in terms of quality and why -- a) Battery produced from Charged plate ( as stated above ) followed by H2S04 Acid filling followed by Bo0st Charge with Battery Charger . At Stage1 a lead acid battery get charged with constant current at the given ~1A value and the voltage will go up 1.8V. thanks kristof. I am now testing the battery with a 1A load to see how many AH it can deliver over the next two or three days. So your system could find a balance itself. (I shall use a external charger for charge bettery) So, I needs to know that If, I use a external Lead Acid Bettery on UPS, So will be any problem on my UPS? Vhody smoothies zvisia od toho, o do nich dte. Thanks, Bob K. This is a very strong forum with a long history of contributions on battery related technology. To control charging current you will need to insert a power resistor between the battery and solar panel. I would like to reserch products before buying so brand names /manufactures of such device would be very helpful. Then you keep the voltage constant at 29.5V until the current drops to approx 100mA. And a 1 ohm resistor in series will indeed keep the current to a safe value under all circumstances. Lower will never do harm, just charge slower. RVC/Pb grids with Pb thickness 10 and 100m were used as negative and positive current collector, respectively. In the end, the battery was tested continuously for ca. E.g. Slow charging or Pulse Charging? The application such as lift truck where the electrolyte gravity would be 1.3 (very stressed-out application) 1.2 in a telephone system application (very relaxed application) Generally 1.27 in automobile application (many cycles, shallow discharges but high energy demands) And again different in an emergency power system, few cycles, deep discharges You mentioned 200Ah batteries; this means the batteries will deliver 10Amps for 20 hours (not 200A for 1 hour. The charging-discharging behavior of the lead-acid cell with electrodes based on carbon matrix, $$ \mathrm{Capacity}\ \mathrm{loss}\left(\%\right)=\frac{C_{\mathrm{disch}}-{C}_{\mathrm{rem}}}{C_{\mathrm{disch}}}\bullet 100\% $$, https://doi.org/10.1007/s10008-018-3981-4, Applications of carbon in lead-acid batteries: a review, Lead-Carbon Batteries toward Future Energy Storage: From Mechanism and Materials to Applications, Electrochemical Preparation of Lithium-Rich Graphite Anode for LiFePO4 Battery, Electrical Performance Improvement of Lead-Acid Battery under the Impact of Micro Carbon Additives, Development of low-cost nitrogen- and boron-doped carbon black cathode catalysts for the improvement of hydrogen-bromine flow battery cathode kinetics, Improved electrochemical performance of silicon monoxide anode materials prompted by macroporous carbon, Preparation and electrochemical properties of core-shelled siliconcarbon composites as anode materials for lithium-ion batteries, Calcium ion pinned vanadium oxide cathode for high-capacity and long-life aqueous rechargeable zinc-ion batteries, Effect of charging protocol and carbon electrode selection in NaO2 batteries, http://ergaerospace.com/technical-data/surface-area-of-duocel-foam/. I always understood a deep discharge was the worst thing to do to a lead acid battery. Patent US 7060391, Jang YI, Dudney NJ, Tiegs TN, Klett JW (2006) Evaluation of the electrochemical stability of graphite foams as current collectors for lead-acid batteries. My question is; does this drop in the third battery indicate a bad cel and should I replace it before I install four batteries for this 48 volt system? The correct setting of the charge voltage is critical and There are several ways to do it, and it will actually depend on some parameters you did not give. Each plate is connected to a spreader bar which is in turn connected to the battery terminal post. I have found adjusting charging logic based on battery temperature to be more important than SOC. Now you put them in series again, use them, and charge them with 27.6V. 2. I want to use 100Ah battery (I will use extra charging syster if UPS charging system not working) So, My question. And I wish to get the MAX BATTERY LIFE. After some time, the current might increase and the battery can be charged and might be usable. below 11V it switches OFF, and it switches ON again only when it goes above 13V. It will stay full and ready for use. A key requirement is durability on the order of 10,000 cycles which further drives using a large number of batteries to reduce the stress (DOD and peak current). was it a fixed current or just a resistive load? Is it Possible to find out the Value of S.G with Voltage before Charging what will be the Values if them corresponding to our Charging Current with duration. This is how many batteries are shipped. This is a "safe charge", but can slowly degrade the battery over time since internal sulfatation can occur. pls anyone :-). Coefficient equals 0.28gcm2 for negative and 0.25gcm2 for positive plates and is much lower than for standard plates based on cast grids [40]. Three step chargers SLA ChargingBasics Lead acid batteries have come a long way. Table 2 compares the advantages and limitations of various peak voltage settings. An expert opinion would be great. Are alternators typically CCCV chargers? Interesting fault here, "bad" battery which shows abnormally low voltage (ie 11.14V) but if the battery is tilted +/- 45 degrees 20 seconds later it recovers back to 11.32V Any ideas? I got the feeling it won't live long, and won't enjoy its life either :-) Also, it won't work with a 1 ohm resistor in series, so you must remove it before the load is connected.That's no real UPS, is it A diode over the resistor could overcome this issue, but it must be a BIG diode that can handle at least 50 amps, with as low as possible voltage drop. So, How much is the CHARGING AMPERE & VOLTAGE ? This is reinforcing my idea about a wimpy charger and a defective voltmeter. If you can find specs on your batteries good, but search around on other similar units. It has been suggested that this type of battery initially needs to be run down completely and then recharged before use. I have a 12V, 185Ah battery and a 20amp charger for it. check-it at http://www.cadex.com/en/products/c8000-battery-testing-system. What method should I employ? Such as installing wrong batteries, IE 36V battery in a 48V system For that reason, chargers and batteries systems should be designed with interlocking mechanism so that charging power is only available after a series of tests have been done If you look at your cell phone or laptop batteries, there is normally no power available at the contacts until both units are properly connected together Some of the criterions that governs what type of wire (wire alloys, and insulating jacket) is suitable are For example, a train catenary (overhead cable) it has to resist abrasion, from a voltage drop point of view, it can glow red if that is acceptable Some cables are made of steel for strength because they have to support winter ice Some are made of aluminum because of their light weight, sometimes reinforced with a steel core for added strength Some are bundled together with others in a hot conduit Some need to resist twisting and pulling like telephone handset Regards Anita, To Marc Saya You need to consult your charger vendor as they are the only people who know how the internal plumbing of the charger works How to set your charger depends on your batteries and the application, if flooded, AGM, gel cells. At 0C it is 13.8V. Also I would recommend the Battery Tender Junior for most sub 100 Ah batteries (and battery banks). (Motors as in a refrigerator or the air blower in my gas furnace.) I would like to know what you would suggest for a charger maintainer to recharge and care for the batteries. But with a charger consisting of nothing more than a bridge rectifier and a series resistor, the ripple voltage and current can be quite important. The measurements results show that the 12-V battery constructed from 2-V RVC/Pb cells retains their good electrochemical characteristics. there are still a lot of minor mistakes in this article such as "During the constant-current charge, the battery charges to 70 percent in 58 hours", if you have a 200ah battery, 200ah/8h*0.7= 17.5A, without considering the inefficiency , you have to use at least a 17.5 amps charger, and if you don't have a 17.5 amps charger, then there is no way the battery can be charged to 70% in 8 hours, so the first graph should be amps against capacity instead of time. I set up a 50W network of resistors to create a loat to discharge them and graphed the in-circuit terminal voltage and current over a period of 25 hours. An 88 Ah 12V battery holds about 1 kWh so 50 hold nearly 50 kWh. If any problem persist i will post here. Let us know what you find. See my stack exchange answer to "Lead Acid Battery Charger Design Factors" which relates, and follow the link there to the Battery University site which will tell you far more than you knew there was to know about lead acid (and other) batteries.. From the above answer note the quotes from the above website. Don't apply that voltage forever, but stop charging when the current has dropped to 10050mA. Before using the following day, the machine must be plugged in and charged until the charger indicates the batteries are FULLY charged. Case 1: When you connect the battery and the voltage drops a bit and current is limiting to the set value, the battery will be fine probably. The primary battery is a pair of 6V golf cart GC2's in series and the secondary is a 12V deep cycle marine. Any clairification is welcome. Thank you Ron and James for your words of advice. People get confused and consider them to be one and the same for the similar core of attributes. The float voltage is reduced. Can it overheat? AGM will do some recombination, flooded plat creates bubbles so you replace water after a long time. Are we talking ripple voltage or current? I've been informed that we may start to use an opportunity charging method (charge a little here and a little there while the lift is not in use, say an hour or two at a time). In any case, 5A is not 5% of 100Ah, they are completely different units! Terminal Voltage will drop and fluctuate once a load is applied to it. A couple of hours charging from the vehicle alternator may not have been enough to fully recharge, and then there was another 6 week of sulfating. It would appear that you are charging at somewhere between 2 and 10 percent of Amp/Hour capacity. This is a converted EV application that has both flooded and AGM batteries in parallel; starting with the flooded ones (the AGM pack is harder to access to inspection purposes), I opened the electrolyte caps, expecting to see a lack of electrolyte (from boiling), but instead I saw electrolyte levels consistently ~0.1" higher than they had been previously! My load looks like 11.85amps overnight. So for 2 cells in series, current is still 500mA. A loco engine used batteries 3 x 8 v / 450 ah were put on charging at about 30 Amp. I remain as uncertain as ever about just what is happening here. Every 6 months I do a complete charge/discharge/charge cycle. I am not sure what is really you question is, but you can't change a 12v using 24v power supply. The big debate is how long would the while be? But if you test right after charging, the voltage is higher; you need to give it some time to settle. Have a 16.5AH ATV battery with life left in it that I switched out with a new one for winter. during charging the voltage and current of charger (using lm317) is 14.4 V and 200mA. Part I: proof of concept. With higher charge currents and multi-stage charge methods, the charge time can be reduced to 810 hours; however, without full topping charge. Bypass it (remove it) after one hour or so. R.D. If it was sulfation, the cure would not be as dramatic. 1.what is the minimum discharge voltage? Be so kind to explain meaning of treatment charge for a battery. Can I replace them with two CSB 12V-34AH compromising only the operation time? The battery has been disconnected during the interruption and replacement with a different battery is possible. Hi,i bought new 12v 7.5ah lead acid batteries for my rechargeable fan. Cell-Con, Inc. is a leading U.S. manufacturer of custom and stocked battery packs and power systems: Lithium Ion (Li-ion), Nickel Metal Hydride (NiMH), Lithium Iron Phosphate (LiFePO4), Nickel Cadmium (NiCd), and Lead Acid (SLA) battery chargers and battery packs used in today's portable device marketplace. Vic, You did not say if your existing batteries are flooded plate or what.I assume your existing charge was purchased for whatever type battery you have. A question: what is the charger type you plan to use? Response to Bob k Thank you for your response of 19th Oct The batteries are in a different country at the moment, so an exact response is difficult As I mentioned the batteries are part of a solar system ad electricity is something I have limited knowledge of. Thanks, to Aatif Anwar: Hi there, I still think you need to add hysteresis like I desscribed above. ok. my battery is good. my 12volts suv v6 battery has very little water, should i pour acid water or demineralised or both? acc, Plz help me, regarding for charging of a 12V dc battery, i have to design a dc dc voltage converter for 12V to 16V ? I will keep the charging for long, @ Agada Idoko Joshua: You can charge a battery and keep the load connected. A cell voltage of 2.10V at room temperature reveals a charge of about 90 percent. Thanks in Advance Ryan, Hi i have Lead acid battery No# 32batteries (UPS) ,but the UPS is faulty 6 month ago, right now i have traditional charger 110VDC,35A using for Nicd battery bank The question Is it possible to use this charger to charge the lead acid batteries and how Nr of batteries for right charging ,time? I reordered new batteries and after waiting for two days received two 12v 4AH batteries. Because I drain the chemical from battery I diry space between cells plates then I have shorts and battery resistance became very low and current will be high. Thanks sooooooooooooo much. If you find only 12V or even lower, you should bring it back to the shop and request a good one. Since this battery has been as high as 1.300, I will push it a while longer. So the - of one battery to the - of the other battery; the + of the one battery to the resistor; the + of the other battery to the other side of the resistor. He's not taking Peukert's law into account. To get the best efficiency and adjustable load for your legs, you can do it as follows: - The 24V DC voltage you make (I assume it is DC, otherwise use bridge rectifier + capacitor) goes into the step-down converter. Bob K. HI, I've been referencing this site for a while and really appreciate the amount of effort it requires to maintain as new info becomes available. Weak cells may go into overcharge while strong cells remain in a starved state. 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. 2023 Springer Nature Switzerland AG. a 12V battery can be connected to a 13.8V voltage source with current limit depending on the battery size. Current will be highest when just connected, and will slowly drop. My automatic charger charges initially at 16V and I am concerned that this is too high. This was not happening before the MMPT was added to the system - I am also wondering if the temperature is is just co-incidental to one cell or may be more being RIP, the batteries are 7 years old and I believe that I did look after them well. Charge pattern for the system is 2.4V per cell CC followed by a CV tail of 2.5Hrs and than a 2.3V float level . (I did briefly look for a DC-DC battery charger but couldn't find anything that fit my needs. In his original post I can't determine if he's designing his battery bank in series or parallel. A smart charger may need you to choose some options before it works as designed. What is causing this to happen These are both marine batteries. So it will make a small difference. I have 25W panel . Is it safe to charge my batteries at 20 aac up to the absorb point 28.0V. @Tele: If it works for a few minutes, I think the battery is not bad, but not charged. This 'Constant Current' nomenclature just seems deceiving. Over-charging also leads to water consumption. You can place them in parallel to do so. Hi! We have impact Silver Hi power souther batteries 12 V 200AH @ C20 @1.250Sp.Gr@27Degree C Can we charge this batteries with External Charger 12 V 6AH. Number and description of charging cycles. The voltage then stays 14.4 (that's the voltage setting of you charger) while the current will start decreasing. The coolant pump draws 146 watts. The real risks with what Doug proposes are 1) if it's plugged in when you start the car, the starter motor may try to pull (excessive) current backwards *from* the small battery, potentially blowing a fuse in the vehicle or, worse, damaging the small battery and/or the car's wiring (i.e. 2) What are parameters ( CCA , OCV , SG of H2SO4 , etc. ) I have 4 Trojan 6 volt T-145 (145 minutes @ 75amps) golf cart batteries connected in series/parallel in my RV.
