I think you will find my new book useful as it has a big chapter on diagnosing just this sort of problem: http://www.amazon.co.uk/dp/1847979955. Motorcycle Voltage Display 4.8A Charging Adapter USB + type-C Dual Interface Charger . If it some type of more fancy battery (AGM, Gel, or something ‘special’ like that), then you might have done more damage as these batteries are more sensitive to having the correct charging rate and voltage. My 12v battery is showing around 8V which shows it is discharged. You really need to know how much current it is drawing from the battery to work out how long the battery should last with it on. Is that low enough to cause it not to turn over or do you think the problem is with something else? Feel free to scroll down to skip right to the steps I have laid out to help guide you through checking your charging system. Make sure your charger is the same voltage (6 Volt or 12 Volt) as the battery you are charging. Charge for a full 8-12 hours.NOTE: If your battery is HOT – STOP. You need to determine the current state of holding the voltage that your battery has to make sure your battery is up for the task. Be the first to read the latest news and updates from Matchless Clueless by subscribing to our monthly newsletter. It powers up all kinds of lead-acid batteries, integrates an automatic mechanism for charging, and is safe to leave connected for a long time. The standing charge is 12.6V at the moment so it looks OK. Do you mean that it draws 0.1 Amps current, or that it lowers the battery voltage by 0.1v when it is turned on? Note that the voltages shown are open circuit voltages which means that there is no electrical load placed upon the battery. Easy mistake to make hey! Each battery has a 2 AR rate of 146 and a Mfg recommended Float Charge Rate of 2.20 V.  Soooo Question is if I hook-up a 1 Ft squarish solar panel to this bank ( which puts out ~ 18V @ 175mA @ 3W ) and leave it alone for months at a time in Arizona ( where one can really cook an egg on the side walk, for 9 months out of each year ) will I over charge or not do much at all?!? Once your battery sits in a drained state (below 12vdc) it will begin to eat itself and discharge at an increased rate. Don’t forget to follow me on my other accounts to stay in touch and up to date on any other content throughout the week! I wouldn’t take much notice of the difference between 12.4 and 12.5 volts. Fast charging is not recommended for daily on-bike charging as it results in gassing and requires careful monitoring and possibly topping-up of the battery. It measured the same the next day at 12.5 volts. Now you SHOULD begin to see a change in voltage. Not sure where you are in the world, but it seems much more likely that the cold temperatures have finished off a battery that was on its last legs. Deeply discharged batteries will have high internal resistance, making normal battery charging difficult. I rode my bike and it stopped and started just fine. Once your battery is charged, you’re now ready to start testing your motorcycle charging system! If your battery is, in fact, lower than 11volts even after you charge it, it may be time to budget out some cash for a replacement. What type of reg does your bike have? Hi Craig. Even a flat 12v battery would give more than 10v. Any ideas what it might be thank you in advance dave. Features. The table below shows the approximate voltages that will be measured across the terminals of a lead acid cell for various states of charge. Anything between 12.06 volts and 12.62 volts means you battery needs to be charged for longer. This category only includes cookies that ensures basic functionalities and security features of the website. It may be necessary to use a charging voltage higher than normal to get the battery to accept a charge. Went on for about 4 or 5 times. The motorcycle battery charging system has multiple components. The voltages you mention seem normal and 14.8/9 volts should make no difference to a device rated at 14.4 volts. When charging conventional batteries, loosen vent caps and ventilate charging area. Gassing is bad for the battery, and also potentially for you as the gasses are explosive! At this state, the only useful energy left in the battery is at around 20-25%, that is unless it has been “Deep Cycled“, which can only be done a couple of times and is not typically used for motorcycles. (Having said that, best to only turn on heated grips when the engine is running as they otherwise draw a lot of power from the battery). thank James for the quick response. Hi Steve. Some intelligent battery chargers may employ such high charge rates for part of their charging program as this can help to maintain correct battery chemistry. Jeff. The battery fluid doesn’t seem to fluctuate. Necessary cookies are absolutely essential for the website to function properly. Doesnt sound like reg/rec… any other ideas? And motorcycle shunt relay controller works so: when the voltage across the winding of the stator winding is exceeded it shunts the generator winding, not giving the voltage … Namely, car voltage regulator regulates the current on the stimulating winding with the intent produce stable voltage on the stator. Check out the above ‘charging voltage’ table for more info. Feel free to share this pages link with anyone you know! I’ve suspected my battery to be dying as it’s not much over 12v each morning and the lights dim when I brake etc. Sent from my DROID RAZR using Motorcycle… This website uses cookies to improve your experience while you navigate through the website. – Your regulator is working because it’s not allowing the voltage to exceed the threshold amount (past 14.8-15volts). Charging a battery on a motorcycle is different from working on your car battery. TESTING INPUT … Any info would be greatly appreciated. That’s probably down to multimeter accuracy, the way the meter was connected, different battery temperature, or other such second order effects. This is how ‘intelligent’ battery chargers work by constantly measuring the voltage and stopping charging once the desired level has been reached. Right after I put everything back together I started getting an issue with the bike cutting out when I was in first gear (only while the bike was cold tho) and one morning it wouldn’t start at all anymore. What would you think of these readings given the circumstances? It was a 12v tender and not 6v. The primary battery voltage is dictated by the chemistry of the lead acid cell. Fully charged and in peak condition, each cell has a voltage across it’s terminals of 2.1v. In fact, if your battery is checked at a “resting state” (meaning no charge or draw is being used and it reads 12.0- 12.01-volts), it’s pretty much considered a goner. I do have a warranty on the battery but afraid it will test out just fine. HOW TO CHECK YOUR MOTORCYCLE CHARGING SYSTEM. The alternator is fitted with a regulator that charges the battery while you ride. My question is the voltage regulator bad as well? Alle der im Folgenden gelisteten 12v battery charging voltage sind 24 Stunden am Tag im Netz im Lager und zudem … Boyer electronic ignitions, for example, will drop out below 10 volts. My bike would not crank over. You should see a symbol that looks like a V with a solid or dashed line above it OR it may even have VDC as your option. Trickle charging means charging a fully charged battery at a rate equal to its self-discharge rate, thus enabling the battery to remain at its fully charged level; this state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load. Should I replace it none the less? Motorcycle USB Charger with Voltmeter and 3.1A Dual Power Port JARDLI It features a digital red voltmeter that informs you of the battery percentage of your … Hi james, I know this thread was started a while ago, but have you got any idea why my motorcycle battery would be reading around 18v whilst idling? All Rights Reserved. Is my battery good, or did draining it down to 9.5 effected the battery’s state of charge. You’re either charging the motorcycle battery incorrectly or your … This site uses Akismet to reduce spam. Keep in mind that not all charging systems react in the same exact parameters that I’ve described. If it’s a sealed battery then no need to top up. Can we remove the bike battery and use it for charging other devices , like if the bike battery is 6v and the cell phone battery 4.5v, Hi. Thanks. This model of the 12-Volt motorcycle battery charger offers multiple benefits for a motorcycle owner. With so many different types available it can be difficult to select which one is the most appropriate for your classic motorbike, but hopefully my ‘Selecting a replacement battery’ article can offer some useful guidance. Kinda makes you want to run out and test your battery right? Thanks James, it’s a sealed battery – does it make sense to unseal it now and check the levels? Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. On older motorcycles/ATV’s (before 1990) the charging system DOES play a role in the ignition system since the coil is energized by a component attached to or around the stator’s output signal. This is just a stationary check. (this bike has starter stall so I always thought my battery was low until I understood the 87 technology) Hi Harry. I left the LED light on over 14 hrs which drained the battery down to 9.5 volts. Picture this: one morning you start your bike as usual and make a quick stop to fill up, but when you go to start your bike back up you suddenly realize that the bike will not turn over and all you hear is the discouraging CLICK coming from the starter solenoid. If a mains charger, well think this might need replacing! These cookies will be stored in your browser only with your consent. You don’t say whether your bike is 6 or 12 volt. Hi James, Nice job on this page. Maybe you get 12vdc, 11vdc, 9vdc, or even lower. I just got a new 6v lead acid battery for my ’47 Indian Chief. Any cookies that may not be particularly necessary for the website to function and is used specifically to collect user personal data via analytics, ads, other embedded contents are termed as non-necessary cookies. But I’m guessing it’s just a standard lead-acid you have, so fingers crossed it will be ok.  Good luck, and please let us know what happens . The tender was hot! When I turned on the ignition, the voltage drops to 12 – 12.1 volts. The minimum charging voltage for a lead acid cell is 2.15v; a little more than the cells own voltage of 2.10v. The majority of classic motorcycle batteries are of the conventional lead acid variety. Been on a battery tender since I bought it (just a few weeks old). Voltage sounds good so hopefully no damage done, but best to avoid such high charging voltages in the future or battery life expectancy could be much reduced. Got it? The normal charging voltage range is how the majority of battery chargers and a classic bikes on-board charging system will feed charge into the battery. (thanks). So if it is below this reading, it’s a good time to put a charge on it for a couple of hours with a … We use cookies to help improve your web experience. Is this too high and will it kill batteries? If so, this is GOOD! Any ideas? Reconnect your positive and negative meter leads to the battery the same way as before. Now what you need to do is read the voltage output past idle by slowly twisting your throttle up to around 3,000 RPM and hold it there. Test the voltage with the bike running at fast idle, roughly between 2000 and 5000 rpm, to confirm if it is getting the correct amount of charge from the bike. I bought a new chunky 12v sealed lead acid battery made by Westco a couple of months ago for a Harley 1340cc bike. Learning how to check your motorcycle’s charging system is way simpler than you might think and at most takes about 1 to 2 minutes. Bought a deauville 700 and got a pair of small led running lights and connected them to the two side light wires.promblems started there now running them off the battery with fuse and switch,but battery went flat tried charging it a few times but every time I start the bike get a series of clicking on the main 30amp wires.Sealed battery reads 12.7 after charge and did just turn over before series of clicking,taking the battery for a test and showing 12.7v he said no amps it’s cooked I’ve got a fluke meter tried testing for amps on the battery without any joy. Hi This isn't enough to charge a motorbike battery. For charging it the charging-system should provide a voltage of about 14.4 Vdc and this should be a constant voltage at all engine-speeds. Regardless of the case, I will be showing you how to quickly and effectively check your motorcycle’s charging system. I'm really starting to think its fine and I need to start the bike … – Your stator has not failed (which would cause the voltage to never make it to the battery). The 16v you describe is definitely too high for charging a 12v battery – 14.4 volts is a suggested maximum. Hi there. You also have the option to opt-out of these cookies. Either way, it looks like you have found your charging problem (the regulator)! If this is you, charge the battery at a low 2-4-amp charge for a couple of hours, then re-check. Applying 18v is not going to do the batteries any good, so you’ll need a charge controller to regulate this to the correct charge current, and also to disconnect the batteries when the suns not shining to prevent discharging. If your battery is floating around 11-12vdc, there is still a chance that it is a usable battery but it will need to be charged. Go ahead and turn your key on to start your motorcycle and let it idle. Copyright © 2010-2016 James Smith for MatchlessClueless.com. They are only called this to distinguish between other types of batteries. I’ve got an 07 wr250f dirt bike which has had a few issues. However, if it is a modern sealed battery then there is obviously no way to check or top up the levels. Don’t run the bike with 18v going in to the battery as that is sure to ‘boil’ or over-charge it. Harry. Please continue browsing if you're happy with this, or read our. The battery is gassing – should I continue charging or am I doing damage? If your voltage is below 12.4V after a charge — you need a new battery. Anything less than 12.06 volts and your battery might be ruined, but you can try charging it more. so put voltmeter across battery (pos Earth) spot on up to 14.55v Tried another ammeter no joy both show discharging when lights on but no charge.checked wiring in series neg to ignition switch all seem OK. Any ideas please. $22.99 Stars 4.4/5. I’m not particularly familiar with RV battery and solar panel setups, but I would suggest that you need a charge controller between the PV panel and batteries in order to regulate the charge. This set up is with a regulator and a stator. I plan to put it in the bike today and get it running. and when rev'ed up it doesn't go past 15. Do you have a separate multi-meter with ammeter function that you can connect in series with the LED? The alternator creates alternating currents to run the bike and charge the battery. We also use third-party cookies that help us analyze and understand how you use this website. The rest of the voltage is lost in the extension cord wire. I try not to poke around but I know it's not charging the battery. The original reg/rec circuit is functioning normally but does not regulate with the accuracy required by the Lithium battery – the charging voltage can rise to 15.2V at maximum revs, whilst the battery manufacturer specifies an absolute maximum of 14.8V. I will check back with hws it did. This is the function for testing any circuit that uses VOLTS DC (aka volts direct current) to operate. If the recommended float charge is 2.2v per cell, that’s 3 x 2.2 = 6.6v for each battery and 2 x 6.6 = 13.2v for the series setup. If not, then you likely have a motorcycle charging system problem. I looked for the one with the lowest charging anps. I just measure battery voltage with DVOM and MCR got 12.38- 166 CCA and tested in vehicle and got charging problem. You'll want to see a reading of 13.8 to 14.5 volts to know that your stator and regulator/rectifier are operating properly and charging your battery. Designed for 6-volt and 12-volt lead-acid automotive, marine, and deep-cycle batteries, it also works on flooded, gel, AGM, and maintenance-free batteries. Also before you begin, keep in mind that on most motorcycles from 1990-2017, the charging system has NOTHING to do with a “no start” or ignition system problem. Simple. Your motorcycle battery stores electrical energy for use and acts as a buffer for the bike's electrical system. After using the bike only a couple of times in January I took the battery out and charged it then disconnected it from the charger. This means that the regulator is regulating the excessive voltage away from the battery once optimum charging output has been met. I’d stop this charging, leave the battery to settle in a well ventilated space and then top up the fluid (if possible) to the correct level with deminarelised water. However, some electronic ignitions are very sensitive to voltage supply, dropping completely out of circuit if the voltage drops below a certain range. Shop can’t get new JL Audio amp to stay on. Took the battery out and tested the volts, got 13.11 volts. Hi James, Shows no charge at amp meter but noticed lights got brighter with revs, Lower charging voltages are useful for trickle (maintenance) charging whereby battery condition may be kept topped up whilst constantly connected to an appropriate mains charger when not used for long periods. With the engine running, I was not able to measure any voltage higher than the battery voltage (measured at the battery). I’ve bought a brand new battery early this year, had it run down a few times and had to get the bike jumped (my stator was fucked) but it has been perfectly fine since. But opting out of some of these cookies may affect your browsing experience. I’m worried it might strand me on 5 day camping trip. Hi there, quick question. Also according to the wiring diagram it has two wire G/W and I can find a harness with to wire matches diagram. Thanks James for an informative article. I have 6 of them for old and newer bikes. Now, I’m not saying that a charging system issue will be the only cause of this example, but it very well could be the culprit as to why it happened in the first place. While you ride, your ignition system, head light, tail lights, signals, horn, blenders and disco balls require electricity to operate correctly. In a hurry? If it’s 6v then 9v will quickly fry your battery as the max charging voltage should be just over 7v. My 8Ah battery is charging with 16V at 1A. Want to change battery with lithium ion batter 3.6×4=14.4v 2-3ampere for replace my 12V 2.5 amp battery, is it make any problem to my accessories ran from the battery [like horn, head light, indicator light, meters/dashboard several lights??? These two systems are separate altogether. I assumed it was simply a loose connection on the battery and took it off to charge it, but the reading is still at 12.37V. This isn't enough to charge a motorbike battery. As can be seen, the ground line of the IC 555 is switched by the NPN BC547 whose base is controlled by the peak voltage from the alternator. A single full discharge won’t have done it much good, but it also should not have done any real damage that a full charge could not repair. Try charging and fully discharging the battery a few times (leave sidelights on overnight to discharge at a slow rate, headlamp would be too quick), and that should help restore and maintain capacity by refreshing the battery chemistry. Hope this helps, regards, James. It does not need to be a top-end, fancy meter that is able to calculate the earth’s mass… a simple voltage reader will do. One person said it’s a bad battery, probably an open cell, 1 cell is bad. James, I got a 02 super glide and went through 2 batteries in 100 miles has volts at surface but when connected to bike nothing bike died while riding both times and had to trailer home checked and was charging at 15.01 at a hard rev. Even the modern ones tend to need some adjustment to get teh voltage output right. I have an on/off switch for the light. Hi Barry. Before you go ripping your seat off in excitement, there is one tool that you must have on hand to make this check possible, a multi-meter. Save my name, email, and website in this browser for the next time I comment. Similarly, when an electrical load is connected to the battery this also drags the voltage down. The relationship between your motorcycle battery and engine functions much in the same way as a car battery. Cheers, One 12-volt motorcycle battery might look a lot like another, but there are big differences inside. 2. i want to know the current produced from this bike?? Grounding wires that use charging system components can rear their ugly heads at anytime making it very hard to diagnose your problem. It is therefore possible to determine the approximate state of charge of a motorcycles battery by measuring the voltage across it’s terminals. Make sure your bike is not running or on in any way during this check. I have an “08 Suzuki SV650. For any motorcycle battery 0.8A is fine and some are 1.2A but for a larger car battery, a 3A (or even 5A) charging ability will come in useful. In order for your battery to stay at its peak operating output for the next time you start your bike, it has to have some way to have voltage/amperage return back. But you may not have done too much damage…perhaps. A battery under continuous float voltage charging … At the start of the day the bike sits at about 12.8v dc. Hi James, I have a Kawasaki Voyager 1700. Considering those facts, I personally have recharged multiple batteries at this reading for long charging intervals and was able to still use them for my daily rider. However it is not recommended for normal charging from the bikes on-board electrical system. Also shown are the total voltages for 3 cell (6v) and 6 cell (12v) batteries as will be fitted to most classic motorcycles. Great, continue to STEP 2. – Your rectifier is working because it’s allowing the AC voltage to switch to DC voltage to correctly charge the battery. It pretty much has to be a regulator issue by definition I think if the voltage from the generator is not being properly regulated! It is not easy to explain the whole process of troubleshooting in a single video. Once I turned on the ignition, without starting it, the voltage dropped .5 volts. They went flat very quickly and now they won’t hold a charge. My battery charger doesn’t charge low enough so I thought I would use a battery tender. 1. The table below shows the correct charging voltage ranges for individual cells as well as 6 and 12 volt batteries for various different modes of charging. After about 8 hours I checked it. Thanks again! 2. On Sixties and Seventies British bikes, the original Lucas charging system can be prone to failure. Is there a date on the battery? In order to get a perfect diagnostic reading for your charging system, the battery must be charged at or above 12.4vdc (you can still do this check with a battery below this number, but 12.4vdc is the recommended peak operating voltage). Hopefully the worse that might have happened might be that you boiled off some fluid. Hi Andrew. 14.6 volts is lower than allowable for other types of batteries, which generally have a limit of ~14.9. Any automotive equipment should be designed to work with a wide input voltage range anyway. I’ve knackered two new battery’s in very quick succession. Are you sure the new amp isn’t faulty? All works fine at idle, but amp goes into protect when throttled up. This should limit the max battery voltage – does the problem still occur? I left the bike alone for two days and it still reads 12.5 volts and started up just fine. By doing this check you have learned that: How To Fully Troubleshoot Your Motorcycles Charging system. There are a number of different types of battery available for use on a classic motorcycle ranging from the traditional ‘wet’ lead-acid unit, to sealed units and on to modern maintenance-free ‘valve-regulated lead-acid’ (VRLA) batteries such as ‘absorbed glass mat’ (AGM) and gel types. Unfortunately, I have a charging problem I need to track down. A buildup of hydrogen and oxygen in the battery or in the charging area can create an explosion hazard. Once turning off the electric grips, it barely started at 12 volts. When a bike is ticking over, the charging system is normally only putting a minimum voltage level (around 12 to 12.5 volts) through the system. Here is a summary, so far: Brand new battery. Made of fireproof materials, high temperature resistant and corrosion resistant, durable and robust, not easy to … Using the information we’ve talked thus far, determine the health of your battery. Check out my affiliate sales storefront with AMAZON where you can find all of my favorite tools! A guide to what a battery's voltage can tell you about it's health and state of charge. These voltages are not however fixed and will vary both with the state of charge (or discharge) of the battery, and also depending upon the electrical load placed upon it. Then the battery started ‘clicking’ (dead battery sound) after about the 5th times starting. Motorbike batteries are made up from a combination of such cells connected in series with engine!
