These heavy-duty automatic “intelligent charging” systems can be programmed with complex charging cycles specified by the battery maker. Not all chargers are compatible with all types of batteries. He also said something about running the battery down all the way and then charging it...which may be another old wives tale and would be very inconvenient as I would be stuck out there on the lake somewhere with no power if I did that. Three batteries/bank: 1 red top, 1 yellow top, and 2 6v golf cart. In addition, your information doesn‘t really address low amperage usage over cycles that are several hours long. We would require more information about your situation. High-rate chargers may restore most capacity much faster, but high rate chargers can be more than some battery types can tolerate. I was wondering about this because wouldn’t that mean the battery will charge slower if it only takes in 5 amps? BatteryStuff Tech With smart chargers, if they are on and charging and they ‘sense’ a load applied to the batteries, they will automatically attempt to supply the load so the batteries will not be discharged. That will add 15% to the consumed wattage by the C-pap machine, for a total of 690 watts/hour. Well, other than listening to him gripe about it and how HIS Skeeter‘s 36V TM system lasts all day and THEN SOME. And, what charger should I use to charge/maintain this 12v 22ah VRLA battery? With the trend for battery technology to increase capacity year on year, an old timer charger would only partly charge the newer batteries. BatteryStuff Tech Ideal charging amperage for both the charger and the battery is about 10% of the battery’s Amp/Hr rating. Rocky I recently purchased a Schumacher SSC-1000a smart charger for my new AGM marine battery. Richard I have an UB121000 12V 100AH – Absorbant Glass Mat battery and I’m wondering if you can recommend me a good charger for it please? Thanks for any light you can shed on this. How Do I Keep My RV Battery Charged When in Storage? I‘m going to have to upgrade to a 4-bank charger to do this. Is there any need to put a power bar/surge protector between the wall plug and the new smart charger? I‘m using a Noco G1100 to keep it charged. These batteries require a fast charge cell voltage of 2.40V for frequent heavy discharge. Many thanks. A trickle charger provides a relatively small amount of current, only enough to counteract self-discharge of a battery that is idle for a long time. Mike Excellent advice & removal of some of the mystery of how to pick the proper charger, and terms used. Steps to selecting the right battery charger Step 1 - Identify the size of the battery you need to charge Batteries sold in Australia are rated in Cold Cranking Amps (CCA) and Reserve Capacity (RC). An intelligent charger may monitor the battery's voltage, temperature or time under charge to determine the optimum charge current and to terminate charging. Onboard EV chargers (change AC power to DC power to recharge the EV's pack) can be: Power Factor Correction (PFC) chargers can more closely approach the maximum current the plug can deliver, shortening charging time. patented 1981 In the end you need to contact the manufacturer of your battery to see what they recommend. Some battery types have high tolerance for overcharging (i.e., continued charging after the battery has been fully charged) and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. If you look into our 12 Volt Smart Battery Chargers: 5 to 10 Amps Section. The battery pack consists of twelve Enersys SBS-EON-190F AGM batteries wired in series for three banks of 48 volts. John great site i love it ya the best u rock i love you!?!? Public EV charging stations provide 6 kW (host power of 208 to 240 VAC off a 40 amp circuit). 4.4 out of 5 stars 380. Full Name Should contain only letters, numbers, and (' - .)! BatteryStuff Tech Are you looking for a single bank charger/converter, or multi-bank? Often a timer charger and set of batteries could be bought as a bundle and the charger time was set to suit those batteries. Products based on this approach include chargers for cellular phones, portable digital audio players, and tablet computers. 2.) Today, you’ll find batteries in a plethora of sizes, shapes, models, and functions; each of which varies depending on the type of battery there is. The 12v batteries have a c20 capacity of 546ah. Other devices may exist, which combine this with other sources of energy for added recharging efficacy. The normal consumption is probably only 600w. Optima “recommends” using 10A chargers on their blue top batteries (if not all their batteries). We don’t mean physical size, but how many amp hours your battery stores. While the gassing can work itself out of the battery vents, some manufacturers do not have large inner cell connectors to withstand that type of charge. Amy excellent website to know more about picking up battery charger,thanks. [citation needed] This extends the life of the battery since memory effect is prevented while avoiding full charge cycles which are known to be hard on all types of dry-cell batteries, eventually resulting in a permanent decrease in battery capacity. If you’re not in a hurry, you can select a smaller charger. Let’s assume that the rating max charging current for a battery is 5 Amps and I have an 8 Amp charger. Had I known it was going to take 12-hours to get a full charge I wouldn‘t have bought the Optima batteries. The starting battery was was obviously fully charged each day; however, depending on the TM battery, one may have been about 90% charged; the other in it‘s final stage (like 98%). 6 kW will recharge an EV roughly 6 times faster than 1 kW overnight charging. Use the link below to see our large selection of battery chargers and 12v/24v trickle chargers. Herb Korn Very informative. Richard An excellent and very informative article, thank you! All charging and discharging of batteries generates internal heat, and the amount of heat generated is roughly proportional to the current involved (a battery's current state of charge, condition / history, etc. After that, the voltage decreases, which indicates to an intelligent charger that the battery is fully charged. BatteryStuff Tech What are the AH (Amp Hours) ratings on the Optima batteries? BatteryStuff Tech For charging off a generator we recommend that you pick a charger that does not have an amp rating that exceeds 25% of your total amp/hr. Nitecore produces a wide range of quality battery chargers for many different needs, and the SC4 Superb Charger is designed to offer premium performance and flexibility. And, finally in order to answer your question about charging… You can select a smart charger that has an amp rating of up to 25% of the batteries AH rating. I would suggest looking at our 3-Bank marine chargers and if you have any questions you can always contact our tech department. Now you may think that is more amperage than using the inverter, which draws 100-240VAC @ 2.1 Amps. Thanks In Anticipation. Chargers are most frequently used with cellular phones, which tend to have a relatively short battery life. Mohan Cool article, saved me a lot of time. Art I liked the article, I just purchased a Evolution 1 Tent trailer and the prior owner installed 2 6v batteries for power and also installed LED lights. Thanks. Popular battery types include lithium-ion (Li-ion), nickel-metal hydride (NiMH), nickel-cadmium (NiCd), and lead acid. If you would like help picking on out please contact our Tech Department. Although portable solar chargers obtain energy from the sun only, they still can (depending on the technology) be used in low light (i.e. "dumb" batteries, which lack any internal electronic circuitry. Also, is an AGM battery also a VRLA battery? My partner lays on the trolling motor well more than I do: however, killing the batteries wasn‘t really the issue. However, many so called intelligent chargers employ a combination of cut off systems, which are intended to prevent overcharging in the vast majority of cases. I have a 1.5amp trickle charger to maintain battery charge. We sell smart chargers that are already pre-configured based off their history of the manufacturers experience. I‘m considering moving to a 36V trolling motor. Some chargers use "negative pulse charging", also called "reflex charging" or "burp charging". Does jumper have to be same size as main power wire? [26] These batteries last longest if the battery is frequently charged; fully discharging the cells will degrade their capacity relatively quickly, but most such batteries are used in equipment which can sense the approach of full discharge and discontinue equipment use. A trickle charger is typically a low-current (usually between 5–1,500 mA) battery charger or one which has a trickle charging operating mode. 1. The batteries are connected in series to produce 12v. Thank you very much for your help. To calculate your total charge time for a battery, a good rule of thumb is to take the amp hour rating of the battery and divide by the charger rating (amps) and then add about 10% for the extra time to totally top off the battery. We recommend 10% unless you need the quickest charge time. When current falls below 1 amp, finish with 3 amp constant current for 1 hour. A phone charger is an important accessory for any battery-charged phone. Your site is a fantastic resource! Universal chargers can charge AA, AAA, C, D and 9V batteries; universal chargers can be smart or timer based. Even so, many batteries left on a simple charger for too long will be weakened or destroyed due to over-charging. BatteryStuff Tech Many battery chargers, such as Battery Tender, Pulse Tech, and Battery MINDer use the 2 prong SAE type connector, which is popular for pig-tail style installations. Dave Bort hi my camper currently runs 2 100ah agm batteries and 1 110ah flooded battery .i have just installed a 100w solar pannel and 10a regultor how should i set the regulator …..for flooded or agm ? My question is: Will a 24V/13A charger do the job on recharging my setup? A battery's management system closely monitors the two charge phases and drops the charging speed during the second phase to give the battery time to absorb the charge … A simple charger works by supplying a constant DC or pulsed DC power source to a battery being charged. Nowadays it is being used to charge wireless phones. How would I charge both systems with like a 2 or 3 bank 12v charger. What do you recommend we buy? You saved me from ruining my batteries!!! Other material says, for the type of low power/long usage above, one should use something with an Ah rating of only about twice what they would probably use in one session on average, so as not to draw the battery down too much in one night, but enough of the total so the cycling is deep enough to preserve battery life by the proper amount of cycling (or something like that ;-). The voltage will not spike to 15 or 16 volts when the battery should be kept at 13.2. Power bank battery technology. Or 10 amps total of all three banks? Cranking Amps: 1000 Is that in the right range? Simple AC-powered battery chargers usually have much higher ripple current and ripple voltage than other kinds of battery chargers because they are inexpensively designed and built. Some power banks are able to deliver power wirelessly. I also have a battery for the generator which is not on a charger. Dan Dettmann I just bought a used boat which has electric trolling motors and a MAXX Ever Start 114 amp hours deep cycle battery. BatteryStuff Tech Yes, that charger is in the recommended range of 10-25% capacity. Tim Hi there. I am experimenting with a machine that runs on 24v. A motorist may keep a charger rated a few amperes to ten or fifteen amperes for maintenance of automobile batteries or to recharge a vehicle battery that has accidentally discharged. Most chargers are not rated to handle a full load and they can burn out. Just make sure the charger is compatible with VRLA batteries (AGM if they are sealed batteries). With two of those charger/converter it would output 100 Amps, however you would have to have an AC source capable of handling them as they each draw 12 AC Amps. Generally, when the ripple current is within a battery's manufacturer recommended level, the ripple voltage will also be well within the recommended level. My goal is to take this battery with me camping and use it with my CPAP machine. Going any smaller just doesn’t work as well when the batteries get older, and start to discharge at a higher rate. Some battery chargers that can be left connected to the battery without causing the battery damage are also referred to as smart or intelligent chargers. Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed an electric transport system (called Online Electric Vehicle, OLEV) where the vehicles get their power needs from cables underneath the surface of the road via inductive charging, (where a power source is placed underneath the road surface and power is wirelessly picked up on the vehicle itself.[22]. If you're unsure of the composition of the batteries you want to charge and you can't find it written on the batteries, you'll need to contact the battery manufacturer. The choice of charger circuit technology is usually a price - performance trade off. The other main reason to equalize a battery is to cause the sulfation to dissolve back into the electroylte, however not all AGM battery manufacturers recommend this processes, as some AGM batteries are not meant to withstand this type of charge. Now I have a 24v 1000Ah battery bank. Everything is 12V. Internal Resistance (fully charged): 0.0025 ohms [citation needed]. [citation needed] This can cause even an intelligent battery charger to not sense that the batteries are actually already fully charged, and to continue charging. Laptop (110VAC) ~2.0 amps for 3-8 hrs/night I understand that when connecting the same batteries in parallel, it will have the same voltage but will double up in the Ah. BatteryStuff Tech I would recommend a converter/charger/power-supply around 45-55 amps, make sure it is at least a 3 stage smart charger. NiCd cells must be fully discharged occasionally, or else the battery loses capacity over time due to a phenomenon known as "memory effect." Only 20 left in stock - … The most important thing is to make sure you have enough charger power to do the job you require in the time you allocate. If you are running that for 8 hours, then your total wattage used will be 5,520 watts. Hookup directly to the battery is the best method of charging. The output of a timer charger is terminated after a pre-determined time. From where can I obtain one, and how do I know it will work. Jeremy Fear Yes a surge protector will be a good idea. Overcharging of the batteries will result in some cases. Lithium, NiCD, Sealed Lead Acid? The process of equalizing a battery causes the battery to heat up and gas. This prevents the battery from ever being below 100% charge, preventing sulfate from forming. Both these chargers are mountable chargers meant to be mounted in the boat with the battery, so they only come with ring connections to be mounted to the battery. Also, what is the draw amount of the trolling motor? This, in turn, will allow the charger to be used to maintain the battery as well as charge the battery. We run this to charge the batteries. What does the charger do differently in AGM mode? What would you recommend for a trickle charger for the PC 680 Odyssey battery? Time to get a genset and charger to keep the batteries healthy. Universal chargers can accommodate multiple sizes and/or chemistries at once. Such high charging rates are possible only with some battery types. I need a converter/charger that will do the job through perhaps a change in wiring? How does it asses the battery if at the same time resistive loads, inductive loads or both are being taken out. Use the link below to see our large selection of battery chargers and 12v/24v trickle chargers. Our preference would be the USA made charger as they are more durable, last longer, and get the batteries to a fuller charger with its DeltaVolt technology. :). The charging protocol (how much voltage or current for how long, and what to do when charging is complete, for instance) depends on the size and type of the battery being charged. Cold Cranking Amps: 800 We live off-grid with a PV array as our only charger. BatteryStuff Tech Typically for a 24v trolling motor utilizing two 12v batteries, along with a 12v starting battery we would recommend a 3 bank marine charger. The 6th step is an OPTIONAL step that can be used occasionally to “recondition” or destratify the electrolyte in flooded wet batteries. The best are universal (i.e. could you please help me out. I installed a new 3-bank, 10amp DualPro charger the same day I installed the new batteries. I‘ve always just had simple ones but this one does far more. From chargers for: electric powered wheelchairs to electric powered buses; starting/lighting batteries in cars to trucks; standby power in telemetry units to pipelines. However, some of our gel cell chargers will work well with the other battery types. (and/or should this be done to protect the bike‘s expensive ECU ie: elctronic control unit?) By 5am THE NEXT MORNING…the batteries were STILL NOT FULLY CHARGED. Admin Due to the fact that we don’t have all the information for your system we would need you to contact us at tech@batterystuff.com so that we can ask the appropriate questions, to get you the answer that you may need. I think these materials have been about higher and possibly shorter-term draw in all cases, but I‘m not sure. I’m sorry but I don’t believe we have a charger for you. You will most likely have to contact the CPAP manufacturer for a 12v accessory meant to run the machine directly off the battery, but it is far more efficient. If your AGM battery came with an acid pack, it requires activation. With a larger battery such as yours we would recommend a marine 12v 10 amp charger such as the NOCO Genius 12v 10 Amp Marine On-Board Battery Charger, or a USA made Dual Pro 12v 10 Amp Sportsman Series On-Board Charger. Once a month (perhaps once every 30 charges) is sometimes recommended. More a case of being curious how intelligent chargers work if you‘re taking load at the same time? My current charger has three “banks”. Now the converter is not operating. BatteryStuff Tech Please keep in mind we only recommend interconnecting batteries that are of the same age, capacity, chemistry, and if you plan to employ them as a battery pack. This technology is said to work with any size, voltage, capacity or chemistry of batteries, including automotive and valve-regulated batteries. What type of charger and how many of them do I need? Pulsed Charge. Typically, a carefully designed simple charger takes longer to charge a battery because it is set to use a lower (i.e., safer) charging rate. For instance, most Li-ion batteries cannot be safely trickle charged, and the damage caused can be enough to cause a fire or even an explosion. Some batteries may even explode. The Vector high frequency battery charger and maintainer The Vector high frequency battery charger and maintainer is used to keep batteries in stored vehicles and battery applications at optimal capacity during the off season. Bandit Can I use a standard (1-stage) charger, set on 2amps to charge my new AGM 12AH motorcyle battery for initial use until I get a smart charger? Thanks, About the size of a large car battery. Some battery chargers are designed to charge AA or AAA batteries, while other chargers are made to charge only C or D cell batteries. A lot of the reviews mention float chargers, which works for storage – but I need something that will ensure the machine is able to run at night, and can be charged via wall socket during the day. United States Patent 4355275, "Pulse-charge battery charger" I upgraded to Optima Blue top batteries a few months ago. Since the unit of the C-rate is typically implied, some care is required when using it to avoid confusing it with the battery's capacity to store a charge, which in the SI has unit coulomb with unit symbol C. If both the (dis)charge current and the battery capacity in the C-rate ratio is multiplied by the battery voltage, the C-rate becomes a ratio of the (dis)charge power to the battery's energy capacity. David You reference an Odyssey AGM battery having higher charging voltages. The first stage is referred to as "bulk absorption"; the charging current will be held high and constant and is limited by the capacity of the charger. I am not sure if the charger is a 3 stage or not ? Some larger power banks have DC connector (or barrel connector) for higher power demands such as laptop computers. We need a regulated charger of the maximum we can run from this generator, 40amp? Patti Kate. However, when you calculate that back to the battery it is pulling 23.18 Amps an hour! Lead Acid? It says to use it on conventional batteries and maintenance-free AGM batteries. Most mobile phone chargers are not really chargers, only power adapters that provide a power source for the charging circuitry which is almost always contained within the mobile phone. A whole range appliances may be plugged in whilst charging the battery. RACQ has a range of battery chargers available through staff patrols. i am making a go kart, planning to connect 4 12v 80Ah VRLA batteries in series. It charged fairly quickly to about 62% then plateaued off. Previous set up had 2 positive wires (6g i think) coming from bow and connected to battery 1 + and the other to battery 2 +…why? Trevor Hello, I was hoping you could advise on battery charging for a large electric boat project. Solar chargers convert light energy into low voltage DC current. The guy was using a 750ml battery tender to charge it but I ran it hard Sunday on a trolling motor...have no idea what percentage of the battery I used was but couldn't fish it Monday because the green light hadn't come on yet. Non-isolated: the battery charger has a direct electrical connection to the A/C outlet's wiring. Same thing happened on morning #2 and #3. When the voltage on the battery reaches its outgassing voltage (2.22 volts per cell) the charger switches to the second stage and the voltage is held constant (2.40 volts per cell). Other chargers, such as Pulse Tech or Battery MINDer removes sulfation with high frequency pulses, not voltage pulses. Then I recommend a 72 volt charger for the entire thing configuration. Fixed mount solar chargers are also known as solar panels. Do you agree? Would connecting the battery in parallel be able to handle 8 Amp charger? VRLA batteries are technically wet batteries, but they are sealed with an internal drip system to prevent the water from evaporating and leaving the cells. Since the Universal Serial Bus specification provides for a five-volt power supply (with limited maximum power), it is possible to use a USB cable to connect a device to a power supply. I’m doing a summer project and was wondering about deep cycle batteries. Since the OP wants it to last for 8 hours, then it seems that the AH rating of the battery would only need to be 460AH (57.5Adc*8H), or a Reserve Capacity (RC) rating of 1104 minutes (8hr*60mins/hr=480mins@25A*2.3 [since the battery has to supply 57.5 A instead of 25A]). Automatic - There are two main types of automatic car battery chargers and they generally fall into two categories. BatteryStuff Tech Charging cables heating up could be the result of a couple of factors. However, we have chargers that are also power supplies (converters). Car Battery Charger 12V/8A 24V/4A Automatic Smart Battery Charger/Maintainer with LCD Display Pulse Repair Charger Pack for Car, Lawn Mower, Motorcycle, Boat, SUV and More.
