If you are concerned this is occurring then fully charge your battery on an appropriate battery charger and then test the battery after resting the battery overnight. If you are planning on storing the motorcycle you can either disconnect the battery, or remove it entirely from the vehicle.

As mentioned previously, a fully charged battery is 12.6 to 12.7 volts and the resting voltage, ideally should be no lower than this. But how does that help us define a half charged or even flat battery? A rule of thumb is that a battery reading 12.4 volts is half charged and a battery reading of 12.2 volts is flat, there are occasions where a vehicle may start at 12.2 volts but this would be rare and you are at a dangerous level where your motorcycle will suddenly not start. Below 12 volts is classed as discharged and the lower the voltage drops is deep discharge and sulphation will occur. Two of my bikes are well-known serial offenders. Both need a fully healthy battery to provide adequate confidence to roam far afield without carrying a rechargeable jump battery. They may start well at home but fail at a later inconvenient location. Such a circumstance leaves motorcyclists to go for a fully functional electrical source to charge their bike’s battery on board. You will first want to make sure you have your multi-meter (also known as a digital voltmeter) set correctly to measure DC voltage, this is indicated with a dashed line and a solid line and above a letter V. You need to have the dial set to 20 which will accurately measure between 0-20 volts. If the reading blinks when it’s not attached to anything, you may need to replace the multi-meter’s internal battery. Reverse connection protection: this 12v voltmeter is easy to read, can monitor the battery voltage in real time, and has reverse connection protection, allowing you to easily understand the battery status. timely grasp the state of battery voltage between full charged and discharged of this dc voltmeter.Voltmeter display: the internal copper material has a longer service life than iron, iron is easy to rust and damage, and can be detected by magnet.(90% of the products sold on the market are iron material) Do you want to know the best charging system for your motorcycle? It is Voltmeter that will update you about the remaining battery and keep you safe. However, fully faired motorcycles present more choices than older motorcycles. Step 3: Join positive wire to the switched circuit A motorcycle voltmeter measures voltages instead of electric flow to monitor the remaining charge on the battery. How does a voltmeter work? There are five main electrical components in a motorcycles charging system that can fail. These are the: Battery, Alternator or ( Stator), Rectifier / Regulator, Cables, Fuses and Relays. But to keep on top of our batteries health we need to make sure the charging system on the motorcycle is supplying the correct amount of power to the battery. We can do this by following the steps below, but first we should mention that some older, classic motorcycles may have a dynamo which charges the electrical system and these characteristics differ from the way an alternator and rectifier charges, also the charging rate figures will differ on a 6 volt battery charging system. For charging details of a dynamo system and 6 volt electrical systems please consult your user manual.

widely compatibility】this qc 3.0 usb charging port fits 12v car, boat, marine, motorcycle, atv, rv etc. suitable for charging mobile phone, gps, digital camera, pda and other usb accessories.Once both the battery terminals are exposed be extremely careful not touch both of the terminals with anything metal, this will cause a short circuit! A healthy battery should show a voltage of 13.4 to 14.5 once the bike has started. It should measure at least 12 volts when a motorcycle is running. What is a motorcycle voltmeter? Similar to the speedometer lighting wire, take the positive wire from the voltmeter and connect it to the switched circuit. A voltmeter measures the voltage of your bike’s battery and it also monitors the charge plus volts on your battery. What should my motorcycle voltage be?
