What is the smallest alternator you can buy?

LONG BEACH, CA — Denso Corporation has developed alternators that provide output currents of 165, 180, 200 and 220 amps; higher than the company’s traditional alternators, which supply up to 150 amps. These new products, and all of Denso alternators, are the smallest and lightest in the world for their output.


Are all alternators 12 volts?

Alternators need to produce more than 12 volts if they are going to be used in a 12 volt battery system. The actual voltage regulator set-point is typically between 14.1 and 14.8 volts and that is why an alternator may be referred to as a 14 volt alternator instead of a 12 volt alternator.


How do I choose the right size alternator?

Your alternator should be capable of delivering rated output equal to the maximum acceptance rate of your house battery bank. In other words, the alternator’s rating should be equal to 25 percent (lead acid) 30 percent (gel) or 45 percent (AGM) of your total battery capacity.


Can you power an alternator with a bicycle?


How do you make a simple alternator?


Is 16 volts too high?

For some alternators, it’s normal to see as low as 13 volts. For some, a constant 13.6 volts is an indication of a problem. For others, it’s normal to see as high as 16 volts for long stretches. Still, it’s perfectly normal for others to see the alternator not charge at all intermittently.


Why is my alternator only putting out 12.5 volts?

– Corroded, broken, loose or frayed wires/connections could cause zero or inconsistent readings on the gauge. – Gauge readings should be between 12.0 and 12.6 volts for this condition. – A reading below 12 volts could indicate insufficient charging, low battery, or corroded, broken, loose or frayed wires/connections.


How many volts should be at the alternator?

A good alternator should maintain battery voltage between 13.9 and 14.8 volts (14.2 is optimum). Even worst-case, with all accessories turned on, there should be at least 13 volts at the battery.


Can an alternator be too powerful?

You can never have too much amperage when it comes to alternators; therefore, you never have to worry about choosing an alternator with too high of a rated output. Here’s why: Amperage is basically the amount of electrical current your alternator can supply. And it basically operates off of supply and demand.


What is the difference between a marine alternator and a car alternator?

There is a structural difference between marine and automobile alternators. The marine alternator has an extra cooling setup. This setup is absent in the car alternators. The reason for this is the location of alternators in both vehicles.
