If you already know that the alternator is rated at 400 Watts (over it’s full temp/speed range) …then you know that it can provide about 28 Amps.
What is the equivalent of an alternator on a motorcycle?
The alternator of a motorcycle is more commonly referred to as the “stator.” A stator is considered a less complicated form of an alternator compared to ones found in larger vehicles such as cars. A stator is usually located inside the motorcycle engine and is considered a part of it.
How many amps does it take to start a motorcycle?
(b) How many momentary cranking amperes can a motorcycle battery deliver. The answer to (a) is typically about 4.5 ampere/hours (i.e. 4.5 amps for 1 hour or 45 amps for 6 minutes. (270 amp/minutes div. by 90amps = about three full minutes cranking time).
How many volts should a motorcycle alternator put out?
Tests on the alternator/stator coil with the engine on:
Depending on your motorcycle, you should get a reading of anywhere between 20 and 50 volts.
How many amps is a motorcycle battery?
While both are typically 12 volt batteries, a motorcycle battery has less Amperage and requires less amp charge rate. Most automotive chargers pump out 13 amps, 30 amps or even 50 amps.

How To Maintain And Properly Charge Your Motorcycle Battery.
| Initialization | Surveying/testing the status of the battery and make sure its functioning properly |

| Bulk Charge | Charging to Full |
What voltage is a motorcycle battery?
A fully-charged 12-volt motorcycle battery should measure about 12.6 – 13.5 volts between terminals depending upon its chemistry.
Does a motorcycle battery charge while idling?
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. During a normal ride, a motorcycle provides about 13, 14, or 15 amps while idling only provides less than 1 amp.
What is the best amperage to charge a motorcycle battery?
When charging a motorcycle or other small battery, the battery charger should not exceed 3 amps. Most automotive types of battery chargers are not suitable due to higher current output. While maintaining a battery at its full state-of charge will ensure optimum life, overcharging may significantly reduce it.
How long does it take to charge a 12v motorcycle battery?
It will take between 4 and 24 hours to charge a motorcycle battery. To see if the process has been completed, you need to check the voltage every once in a while.
How many amps does a Harley Davidson battery have?
HARLEY-DAVIDSON DIRECT REPLACEMENT BATTERY 950 AMP.
What is voltage of fully charged 12v battery?
12.6V volts or above – Your battery is healthy and fully charged. No further action is required. 12.5 volts – Your battery is at a healthy state of charge, but we’d recommend re-checking it within a few days to ensure the voltage hasn’t dropped any further.
How many volts do you need to start a motorcycle?
A healthy 12 volt battery should ideally register around 12.7-12.8 volts at rest, but anywhere between 12.5-13.5 volts indicates a serviceable battery. Once a battery drops below 12.4 volts, your bike will struggle to start, and at under 11.8 volts, 12 volt batteries are considered to be dead.
Can you jump a motorcycle with a car?
It is possible to jump start a motorcycle with a car. This method should be used as a last resort as there are a lot of risks to the motorcycle. When a car is running, the voltage can run high enough to damage the electronics that are on a motorcycle, but if you’re careful, jumping it with a car is a valid option.
Can you charge a motorcycle battery at 2 amps?
The rule of thumb is that you should never charge a battery at more than one-tenth its rating in amp hours. Meaning that a 20-amp battery should be charged at no more than 2 amps over a 10-hour period.
How long does it take to charge a motorcycle battery at 10 amps?
How long a battery will take to charge will depend on the amp hour of the charger – the higher the amp hour, the quicker it’ll charge. For example: 10 amp hour battery = 10 amp charge per hour = 4 hours to charge 40 amp battery. 2 amp hour battery = 2 amp charge per hour = 20 hours to charge 40 amp battery.
What does Ah mean on a motorcycle battery?
Battery Ratings
Powersports batteries are rated in Ampere-hours (AH) and/or cold cranking amps (CCA). A battery’s ability to discharge a given amount of current over a specific length of time is the AH rating.
