Harley-Davidson motorcycles use either a 6 volt or a 12 volt battery.
Is a motorcycle battery 12v or 6v?
Most motorcycles use a 11v electrical system with a 12v lead acid battery. These batteries are physically smaller than those found in cars and so are of lower electrical capacity. This is not s problem as there are less gadgets and gizmos to drive than on a car. Some earlier vintage motorcycles may use a 6v battery.
What is the normal voltage of a motorcycle battery?
A healthy 12 volt motorcycle battery should maintain a range from 9.5 – 10.5 volts under the load, for a good 30 seconds straight. If the battery begins to hold and then steadily declines, there is a problem. If the voltage drops to 0 volts, there is a problem. We call this, the open cell.
How many volts is a Harley Davidson Sportster battery?
A fully charged AGM battery has an output voltage of about 13 volts.
Can you use any 12v battery on a motorcycle?
As long as your using a 12v battery on a 12v system it will work. That is all. Yes. As long as it’s the same voltage.
Why do motorcycle batteries die so fast?
All too often, motorcycle batteries die young, murdered by neglect. Dehydration, improper charging, and a slow discharge during storage all shorten a battery’s life. … To prevent these draws from killing your battery, you could disconnect the battery, but even if there is no load on them, batteries self-discharge.
How many amps does a 12V motorcycle battery have?
Depending on the bike the performance capacity should range between 2 to 36 Amp/hour and it can be either 6 or 12 Volt. CCA(Cold Cranking Amperes) can range from 30 to 540A.
How do I know if my motorcycle battery is bad?
If your kickstand is up, and the bike won’t fire, this switch may be faulty. Consider, too, that if your headlight comes on and is typically bright, and your horn sounds normal, a dead battery is unlikely. Telltale signs that the problem is the battery include weak or nonfunctioning lights and horn.
What should a 12v motorcycle battery read when fully charged?
Always verify battery state of-charge before charging, and 30 minutes after charging. When a battery charger has been disconnected from the battery for one to two hours, a fully charged Conventional battery should read 12.6 volts (12.8 volts with Sulphate Stop) or higher.
How many volts should a Harley stator put out?
With the Stator unplugged from the VR and the bike in neutral, start the bike. Run the bike at 2,000 rpm and check the Stator output between sockets 1-2, 2-3 and 1-3. The voltage should read approximately 32-46 Volts AC, for the 50 amp Stator. Stators with other Amp ratings will be similar.
How do I know if my Harley voltage regulator is bad?
Harley Voltage Regulator Symptoms
- Gauges flicker. One of the first symptoms you discover when your Harley voltage is going bad is that your bike’s gauges show dim or flickering signs. …
- Instrument cluster fails to power. …
- Clusters display inaccurate or erratic readings.
How many amps do I need to charge a 12 volt battery?
Most battery manufacturers recommend sizing the charger at about 25% of the battery capacity (ah = amp hour capacity). Thus, a 100 ah 12 volt battery would take about a 25 amp 12 volt charger (or less).
How long does it take to charge a 12v motorcycle battery?
So, how long does it take to charge a motorcycle battery? At least 6 hours and up to 24 hours. A brand new lead acid, 12 volt battery under a constant-current charge, will take 5 – 8 hours to charge up to 70%. The remaining 30% will require another 7 – 10 hours before it is ready to install on the motorcycle.
Are all 12 volt batteries the same?
Simple answer – No. Different types of battery have different maximum currents they can supply. This is limited by their ‘internal resistance. ‘
How do you check voltage on a motorcycle battery?
Turn the multimeter on to the 20V DC section of the scale. (If you have an autoranging meter, just go to “V,” because you won’t have a scale.) With the bike completely turned off, touch the black lead to the negative post of the battery, and the red lead to the positive post. Record the voltage.
