But the facts are that there are circumstances that create the issues where the battery can go into what is called Thermal Runaway. I saved almost 6 pounds compared to the previous battery on my Hypermotard 1100 Evo SP. 120Ah battery ANTIGRAVITY BATTERIES. Q:How do client charge battery? Please visit our Authorized Dealer Map to find one near you. It would be nice to have a 10a under load voltage chart too. About Phenomenal Product! See the FAQ above for when to choose Small Case over Restart. The meters on the other hand can get way off. My shunt meter says the batteries are at 91%. for long periods of time daily. I combine the batteries whenever we lose power for more than a few hours so we can run TVs, fans DVD player and lights etc. So don't use that charger. Your 13.2 reading is quite good. The Antigravity Battery normal voltage is 13.2v. Yes a “best in the business” 3 year warranty; please visit our Warranty page to learn more. For example you may want a higher capacity battery if you do a lot of motorcycle touring. 60% 36.72 With the … I can’t believe the difference. 3. Therefore we only recommend using a specific lithium charger for motorcycles and vehicles using LIFEPO4 batteries. Keeping lead acid much below 2.1V/cell will cause the buildup of sulfation. So in some circumstances the Small Case version can be more beneficial for certain applications where you may need a battery that won’t shut off if the voltage gets too low, such as for airplanes or some newer cars that have a start stop system. The battery will read up to 14.7V immediately after charging. 40% 35.88 There are several ways to determine a battery’s SOC. But if you are a regular street rider not often going on longer road trips you will be fine with the regular version of the battery. While on float charge, lead acid measures about 2.25V/cell, higher during normal charge. The bike is an older 1960s through 1980s motorcycle that has an older style voltage regulator that has gone bad. if you managed to get battery to charge back up to normal range above 12.8v .. battery needs to be charged at .5C to 1C for best reforming charge. I researched as many battery manufacturers that I could find regarding their own published SOC data. So thanks for the chart good information. 20% 34.98 This type charging voltage is not acceptable for a lithium battery for its large AC ripple at low frequency (< 5kHz and >1.4V) will damage the cells due to heating and plating (see the above section for lithium battery charging requirements). Ex. Or is it fine. Based on this image, and the data logger, I know the battery attained 14.4V at around 19 minutes. My immediate thought about the differences in your two battery banks is that the wally world batteries are newer, or less heavily used than the Trojan. It doesnt help that the manual makes little sense to the layman or that the meter cant read battery voltage and often keeps compounding small errors into bigger ones. 1. I have heard this is too high of a voltage to keep a battery at! Note: For best accuracy when measuring battery voltage, the battery must be in ‘open circuit’ condition (at rest, or ‘resting’). Most of the bikes from these eras had a mechanical voltage regulator that due to age is now defective and not controlling the voltage and charge to the battery. This means that the battery must NOT be under load and it must NOT be charging. This should NOT be used with a Lithium Battery and unfortunately would be a condition that would damage a Lithium Battery. The meters that you can get that take their info from the inverter or in the case of Midnite Solar from the charge controller are more accurate because they temperature compensate but they need fine-tuning as well. Baby those batteries for longest life. As an Amazon Associate I earn from qualifying purchases. 2. My other set up has about 750 watts of poly panels, run through a xantrex 30 amp charge controller charging a trojan 12 volt golf cart battery. The maximum voltage the battery should be exposed to is 14.7V. We offer the strongest warranty out there. That powers a flat screen TV, charges laptops etc. not a battery tender please. 30% 35.43 Do you trust the voltage meter that you’re using for accuracy? Our Small Case size batteries will work for fitment for most older bikes being they are a Universal Fit. Measure its voltage with a volt meter while open-circuit, no load (general approximation). 10% 34.53. A very highly rated ‘smart’ 12-volt battery charger:(( Most Reviewed Battery Charger on amzn )), Open circuit voltage, or specific gravity per cell, Download full size PDF (Battery State Of Charge). Ive had when rebuilt 12v it stayed at 12.90 13.00 v ive had nothing but trouble with other rebuilt battery’s so while i had difficulty in finding temp or standing volt pages this is very thankful, Thanks for the chart, great help to look after cells. While lithium batteries require a special charger, I have not needed it to maintain the charge on my battery as most of my rides last at least 15-20 minutes and it keeps it charged up completely! Charge verification: the voltage is limited at 13.6V while the ampmatic processor monitors the current absorbed by the battery. Installing a low voltage battery alarm can save your bacon. With the engine off, you should get a reading of 12.6 volts. Smart chargers work with most battery types and use the battery’s voltage to detect the type of battery and charge needed. If the gravity of each cell stays relatively the same (usually all in the green) does that mean that I don’t need to equalize that battery? A:Antigravity Batteries comes prepared to introduce, and start the bicycle/vehicle. We have a 4-amp and an 8-amp charger. The Small Case battery often has a bit more amp hours than the Restart version. But first, a few important notes and caveats…. The Antigravity Battery normal voltage is 13.2V. 80% 37.50 Large stationary batteries at 25°C (77°F) typically float at 2.25V/cell. As long as the battery fits into the battery tray of your bike and can be connected correctly and safely a larger size will not hurt the bike but just allow for more Power and Capacity in Amp hours. The standard meter for years has been the Tri-Metric meter but I finally gave up on using them because they arent very accurate unless fine-tuned beyond the level most homeowners are capable of understanding. Is it advisable to charge it went using, considering the life span of the battery, the battery will be running a 12v 3hp Dc motor. Thanks again! I don’t have to wake up to pull starting my gen set each morning. Many (most) alt-energy systems incorporate a DC-shunt which keeps track of SOC by monitoring the current flow in and out of the battery or battery bank, which is a very accurate way to track state-of-charge. During Covid we're Open and Shipping normally. EVERYTHING YOU NEED AND MORE. It has been keeping my lead acid battery at 13.2 volts, this is at the minimum “HVD” setting. (Only applicable to non-Restart batteries. Or if you have a race car then you may want to contact us to personally help you choose the best battery for your application. Another reason for a battery swelling is that the user is charging the lithium battery with a lead-acid charger or a battery tender type charger. Easily monitor your battery status through your phone using our App. Our Restart batteries are intended to replace the battery in those stock vehicles and our part numbers reflect the same part numbers typically of the manufacturer’s stock battery. 20 Minutes @ .4C Absorption Voltage Attained. Check out our line of batteries that can save you 12 pounds of weight just replacing the battery in your Motorcycle, or 35 pounds in your performance car. Not for 6 volt or 16 volt lithium batteries, or for lead-acid batteries of any voltage. They protect against occasional spikes in voltage beyond 14.8. If we do make a custom battery it has to be within the sizes of cases we already make and only some sizes can be made with a larger battery inside of them. We do offer two brands of Lifepo4 chargers: our Antigravity brand and the Optimate brand. It would be wise to buy a desulfator unit for your batteries in order to reverse sulfation of the plates after long periods of less than 100% charge. Using other chargers can potentially cause an explosion or fire. But we do not make sizes for older bikes because they are not made and rarely requested from customers. With any energy dense battery there is a potential for fire to occur. (This article has been updated since its original publish). It’s like a fuel gauge. This prevents it from being used in an application too large for what is intended. You can download this PDF sheet for specs: You can also see the specifications of each battery on its product page. Simple to install and track your battery’s health and status. What is the state of charge of the following specific gravity:1.287, 1.243, 1.128, 1.200, and 1.135 reading from Hydrometer? As you increase the voltage to get faster charging, the voltage to avoid is the gassing voltage, which limits how high the voltage can go before undesirable chemical reactions take place. I have combined them a few times, then manually started equalization. Yes it will over charge the higher charged batteries, which is why the equalizing charge is only applied for a short time, however if the system uses a single battery equalization is not required and can be detrimental. Having a reliable portable car battery charger is important for bad weather, vehicles with older batteries … 1. The Small Case is a favorite of custom builders, and can also be ideal for racing. Make sure you compare warranties in detail. It gets hardened on with heavy cycling. They prevent the vehicle from draining the battery below 8 volts during cranking. When selecting a charger for either chemistry, it is important to chose one that will stay between the limits listed above. Our Small Case batteries are most often used in applications where the vehicle has been heavily modified and there is no longer space available for the OEM/stock battery. The User’s Manual has much more information to get the most from your product, and safely install, maintain and operate your new Lithium-Ion Motorsports Battery. This will ultimately depend on the vehicle’s motor size and if that motor has high-performance parts and was built either “tightly” or “loosely”. Smallest, Lightest, Most Powerful Lithium Motorsports Batteries - the First with Built-In Jump-Starting! The CTEK Chargers start their charging using a higher voltage (12v) and our BMS will stay “OPEN/AWAKE” since it is seeing the charger produce 12v. The voltage should not be allowed to drop below 10.5V while at rest. 3. We have used only the highest quality components in the building of our batteries. As you increase the voltage to get faster charging, the voltage to avoid is the gassing voltage, which limits how high the voltage can go before undesirable chemical reactions take place. This can be dangerous. Carl, Thanks Carl, and as you insinuated, there are variables, including temperature compensation measurements and others. Just bear in mind the caveats listed above. Here at 20 minutes, with the voltage now held steady at 14.4V (green CV/constant-voltage light on) we can see that the charge current has already dropped from 42A to 41.5A or a .5A reduction in accepted charge current into the battery. Do not leave a battery connected if you know you will not be riding for a long time. This chart shows the battery voltage rate against the its discharge capacity. It has the capability for large weight reduction in the most compact size in lithium batteries in its class. In comparison our Re-Start (RS) batteries are intended more for direct replacement of lead-acid batteries in stock vehicles or mildly modified vehicles. I mainly use this system for 12 volt water pumps,a few LED’s and cfl lights and occasionally power tools. This battery should last about 4-5 years, but this will be determined ultimately by how it is used and treated by the consumer. These chargers can overcharge lithium batteries and will cause damage to the lithium battery which include swelling and overcharging with the potential for causing a fire. Except with some vigorous efforts at reversal. Though we can make a special battery for some persons who may want a higher capacity battery, in general we do not often do this. So they fit directly into the size format of the lead-acid battery they are replacing while offering a number of protections plus our “restart” feature, which offers a reserve capacity. For comparison: the Restart battery has a full battery management system with the restart feature and prevention of over-discharge and damage to the battery if the battery was to be over-discharged by leaving the lights on, etc. The Small Case batteries do not have a full protection battery management system like the Restarts. But in racing and abusive use the lifespan may be much less. This is helpful information, thanks for gathering all the data! A regulated charger will hold the voltage to 13.5 to 13.8 volts once the voltage has peaked, to prevent gassing and overcharging, and the current will drop to almost zero in a healthy battery. a single 12 volt battery consists of 6x2v cells in series and will indeed benefit from equalisation.With a wet cell battery this is easily demonstrated using a specific gravity tester. No. I sent him a link to your chart and told him to call Magnum tech support to learn to tweak the meter. I have Trojan GEL battery 225Ah when I unplug the charger, it reads 13.2v after 24 hr. I would highly recommend this to anybody. I MUST use compression releases 100 percent of the time and I've replaced 2 or 3 starters learning that lesson. In fact, good charger systems (alt-energy systems) have temperature compensation built-in. Just make sure you are disconnecting the vehicle if in storage and that you do not over-charge or let the battery drain below 11V and all will be good for a long time. The maximum charging rate will depend on the battery model, and can be found on the battery’s front label. Here are extrapolated numbers for a 36v system. 3. This restart feature is like having built-in jumpstarting. Do remember that battery voltage readings are temperature dependent. The Antigravity brand battery ), 2. I just wanted to let you know good work on the chart and description. Works on all 12V LEAD/ACID batteries (we also have Lithium version). Secondly pulling voltage down to less than 50% remaining capacity permanently devalues the battery. The peak charging voltage for Gel batteries is 14.1 or 14.4 volts, which is lower than a wet or AGM type battery needs for a full charge. If the battery isn’t fully charged, it will diminish to 12.4V at 75%, 12V when it’s only operating at 25%, and down to 11.9V when it’s completely discharged. Generally, when using our Small Case batteries, the AG-401 can be used in motorcycles up to 450cc, the AG-801 can be used in motorcycles up to 750cc, the AG-1201 can be used in motorcycles up to 1200cc, and an AG-1601 can be used in motorcycles up to 1800cc. This allows you to restart your vehicle if it is accidentally overcharged. Here are a couple typical reasons why the battery may be overcharging: 1. That leads to overcharging of some of the batteries in the set. Examples of best uses can be found on any battery’s page. It will charge the battery to its intended peak voltage and will shut off when the battery is charged. Visit our Downloads page for other product info documents. What is going on here? OptiMATE Lithium 4s 0.8A, TM-471, 8-step 12.8V 0.8A sealed battery saving charger & maintainer. The voltage should not be allowed to drop below 11V while at rest. The chart is listed below. Charging beyond the specified limits turns redundant energy into heat and the battery begins to gas. Just thought it might be helpful to add that one tool I’ve found useful is the little floating balls thing for checking individual cell status in lead acid batteries. Overcharging (and equalizing) leads to water loss. Add to Basket. The batteries are 3 years old costco interstates. 1. EVERYTHING YOU NEED AND MORE. ... On the lower end of the voltage range the battery should be put on a charger if the battery voltage gets drops below the 12.5V range while sitting. But if you Race you might want to get a smaller battery for extra savings on weight since you will not have all the accessories of a regular street vehicle. This is good for preventing “parasitic drain” issues. Get answers to frequently asked questions on proper charging methods, choosing the right size, what to know about lithium, and how to avoid issues. It charges and works perfectly fine with all 12V vehicle systems, provided the stock system is charging correctly. For example if you ride more often on longer distance rides, like Touring or Adventure riding, you would want more AMP HOURS (Capacity), so you would want to go with the Heavy Duty (HD) Versions of the Batteries. please advise to us how we can solve this problem. Thanks for the PDF, newby to solar power. Thanks. From everyday riders to world class racers Antigravity supplies them all. Thanks Ken. Our most recent batteries – the RE-START line of products – have a complete Battery Management System (BMS) that offers the protections needed inside the battery so it cannot get to a point of Thermal Runaway. Subjecting the battery to a constant charging current above the “max charge” current stated on the label. Running a few appliances just to test it. Where the problem can occur is when charging the battery with a standalone charger. But being that Lithium-Ion is a newer technology, please make sure to read the User’s Manual and review all the product safety information before use and installation. However I averaged all of them together to come up with a chart which represents what I believe to be a good GENERAL indication. I put together the following battery state of charge chart which indicates the state-of-charge (percent) as it relates to battery voltage or specific gravity. I realize now I was really punishing them… But certain circumstances should be avoided and proper care and maintenance of a lithium battery is vital to help avoid this condition. 7. 2. My last set of batteries I let go down to 38 volts before charging. But it should be noted that this depends specifically on the application in which you intend to use the battery – for example if it is a custom bike with a high performance motor you should go up one size. We use Lithium Iron Phosphate also called LifePo4. More is always better. 50% 36.30 16 posts • Page 1 of 2 • 1, 2. If the battery temperature rises more than 10 degrees C, you must stop charging the battery. 2. IF your vehicle’s charging system is in good working order and you do not have any “parasitic drains” on the bike you should not have to charge this battery; rarely if ever. Note: If testing specific gravity (deep-cycle flooded/wet batteries), when drawing a sample from the battery, fill and drain the hydrometer several times first before settling upon a measurement. A battery will only sustain damage if the charging voltage applied is significantly higher than the full charge voltage of the battery. I agree with the terminology that ‘resting voltage’ is a more accurate representation…, Thank you for the PDF chart, very useful for AGM battery. We use what is called a prismatic/pouch cell. The Antigravity Battery Tracker is a Bluetooth Monitoring system for your vehicle battery. If you’re storing the battery out of the bike just put it in a cool dry place and cover the terminals with tape to protect from accidental shorting of the positive and negative terminals. See your battery manufacturer recommendations regarding charging. Generally speaking, the less you discharge the battery before recharge, the longer the battery will last. ANTIGRAVITY BATTERIES is an industry leader in lightweight, hi-power lithium-ion batteries for Motorsports/ Powersports. Privacy Policy The gravity on that one varies constantly, and I have to add water more often. Specifically for series batteries. I’ve been wanting to maintain my system more accurate. Much depends on plate thickness. 1. See the Chargers and Maintainers we offer for Lithium-Ion Starter Batteries. I guess my question is do I need to do this since the wally world batteries always seem to be in good shape as per hydrometer readings? The plates may have become heavily sulfated enough that the equalize mode can’t get it all off into solution. The type of use as a “starter battery” application provides for long life especially if all is well with your electrical system. is this for all battery types? And want to really take care of these babies. 2. The maximum voltage of these chargers, whether AC powered, or using a car's alternator, is 14.4 volts. These batteries do not have the full battery management system that our “Re-Start” batteries offer, but they actually offer a bit more in terms of pure power and a bit more amp hour capacity.
