motorcycle battery voltage and amperage

If your reg/rec isn't regulating voltage properly it might be sending too much voltage into the motorcycle's battery. AGM batteries may have slightly higher voltage readings after a full charge. However, more important … Maybe your voltage regulator ain’t regulatin’. The rate of self-discharge depends on ambient temperature and battery type. RevZilla photo. These temperatures can be reached if the battery is stored in a garage or shed in hot weather. The Rectifier/Voltage regulator is often a separate item. Here we have the two main styles of multimeter. If voltage drops below 13.8 the battery will not fully charge. For example, a battery that has just been subject to prolonged cranking will receive a higher amperage output from the alternator than if the battery were fully charged. This type of DVOM will "figure out" the voltage scale on its own, so to test a moto battery, all I have to do is turn the knob to the "V." On the meter to the right, the RevZilla house junker, I have to select the scale, so it gets turned to the "20" scale on the voltage portion of the meter, which is indicated with (surprise!) Note that this isn’t the “right” way to do this, but it’s another clue to help you confirm or deny your battery’s health. In real terms, it’s that initial burst of power required to start your motorcycle. CCA: Technically, the CCA is the number of amps your battery supplies at 7.2 volts … When to Change Your Motorcycle Battery & Understanding Battery Voltage Electrical 0 Christopher A sad fact in a motorcycle’s life is that motorcycle battery issues are generally only addressed when it is too late (i.e. For example, a 12AH battery can produce one amp of current flow for 12 hours, or two amps for six hours. See our Is your sidestand up? Low state-of-charge can be caused by short trips that aren’t long enough for the vehicle’s charging system to recharge the battery. No meaningful charge. your ZillaCash Rewards on a future order with us! If it ran fine on a 20A maximum supply, then your 22A battery will also be fine. the battery is already dead and/or you are stuck on the side of the road). See what our customers are saying about us: Earn $5 for every qualified $100 you spend. So you're ok with 1-2 amps over your original specs, but putting a 12A battery instead of your 6A might be asking for trouble. However, if the voltage drops to something below 1.1V is already a dead battery. Who knows? (Does the bike have a parasitic draw that’s normal, like a clock or blinking security alarm light on it?). During a normal ride, a motorcycle provides about 13, 14, or 15 amps while idling only provides less than 1 amp. 30 percent. A ‘6v’ battery is comprised of three cells giving a total voltage across it’s terminals of 3 x 2.1v = 6.3 volts. Did you know your key fob (if equipped) might use a battery? Common battery Ah ratings are 10,12, 14,16,18,24. For a battery that is of the standard quality from manufacturers, the value you get (on average) is usually a rate of 45-amperage per hours in terms of potential capacity. (If you have an autoranging meter, just go to “V,” because you won’t have a scale.) This battery (and bike!) This lithium-ion motorcycle battery charger makes a good choice as the charger and maintainer. To keep the battery’s capacity high enough to operate the starter it will have to be charged with a battery charger when the vehicle is not in use—about once per month for a Conventional battery depending on temperature. Most 12V bike batteries increase in amp-hours in increments of 2A. A chemical by-product of this process is lead sulphate that coats the battery plates within each cell reducing its surface area. A good battery should not drop below 9.6 volts over 10 seconds or so. So the Watts would be: … You may use a voltmeter to test how much power is left in your alkaline batteries. If you have not, your starter may be drawing an unacceptable amount of current, or you may have bad or corroded battery cables. But maybe it's not the one you suspect. Bad batteries place a heavy burden on a bike’s charging system. 1.Battery voltage is (off charge and stable) >12.7V 2.Fully charged battery voltage never drops <10.5V during full speed start attempts. Caution: Always wear safety glasses when handling batteries and charge them in a well-ventilated area. However, modern battery cases are made of polypropylene plastic and can be stored on concrete without any concern for excessive self-discharge. With a larger battery such as yours we would recommend a marine 12v 10 … Batteries with an open circuit voltage below 11.5 volts may require a special charger and procedures to recharge. Most automotive types of battery chargers are not suitable due to higher current output. A weak, dim headlight is an excellent indicator your battery’s not up to the task of starting your freedom machine. This causes the battery to discharge or produce electrical energy. The larger battery has more potential for work than the smaller battery. Once a battery drops below 12.4 volts, your bike will struggle to start, and at under 11.8 volts, 12 volt batteries … Membership Options. charging the battery of a motorcycle Although voltage drop can occur due to many reasons, we’re going to share a couple of reasons that might be useful for you. If you've got one, refer to your battery manufacturer's recommendations.). Turn the multimeter on to the 20V DC section of the scale. Redeem Amps and Volts: When you're choosing a charger, the volts have to match the volts of your battery (i.e., a 12V battery needs a 12V charger). If the battery begins to hold and then steadily drops in voltage, there is a problem. When the battery loses voltage, it happens due to the weak cells, state of charge, and the load connected to it. Even though you are testing a 12-volt battery, you should know that a battery that is truly 12.0 volts is a boat anchor. 10 percent. Put the Red probe on the the positive (+) terminal and Black to negative (-) earth terminal and check the initial Battery voltage. If you have a load tester (a "toaster," so named because electrical energy is converted to heat, making the device quite warm when in use), now is the time to use it. A common misconception about battery storage is that if one is left on a concrete floor it will self-discharge rapidly. The battery is a new battery, so it shouldn't have any problems. The same battery stored at 40ºC loses 50% of its capacity in 4 months. For instance, at C/5 a battery might safely provide 26.8 amp hours. A battery tender for a motorcycle is a device that plugs into any standard AC wall outlet and transfers power via amperage to a motorcycles 12-volt battery to keep it charged. Jump to Latest Follow 1 - 7 of 7 Posts. Sometimes replacing a battery is financially painful, but the right thing to do. When charging amperage exceeds the level of the natural absorption rate, the battery may overheat, causing the electrolyte solution to bubble creating flammable hydrogen gas. Hook up your DVOM in the same manner you did for the standing voltage test, and have an assistant thumb the starter. Battery Discharging & Charging Characteristics for Motorcycle and Powersport batteries. Then I put my battery on my Harley Davidson brand 750 mAh tender. Any tap installed along the pipe can be considered as ‘load’. RevZilla photo. The starter should be running at normal speed. (Lithium batteries spring to mind immediately as a battery that has a different usage and test scenario. Most modern motorcycle batteries can recover from sub 11v using the correct type of charger. $42.99. This means that is supplies 26.8 amps in the duration of 5 hours without dropping off. A $100 battery pales in comparison to the $500 you might have to spend to replace a stator that your battery wiped out. Try charging it, but it might be toast. At temperatures above 55°C self-discharge is even more rapid. RevZilla photo. The electrical energy used to charge a battery is converted back to chemical energy and stored inside the battery. Find out why your battery went bad! The electrolyte solution contains charged ions, made up of sulphate and hydrogen. Be in the know on whether you actually need a new motorcycle battery or not. Charging times will vary depending on type of charger and the size of the battery. (If you’re in your garage, you can simply light up a headlight connected by wire to the battery if you know how, regardless of how the bike is wired.). What is the Big Deal about Overcharging the Battery? Applying a charging current to a battery, without overheating it, is called the “natural absorption rate.”. Technically, a motorcycle battery does charge while the motorcycle is idling though it does not provide as much amperage as when the motorcycle is at higher speeds. Discharging or charging is always occurring inside a battery at any given time. Maybe you have a bike that’s not starting, or maybe you want to make sure your bike doesn’t get to that point.
