How do I match my alternator to my battery?

How do I match my alternator to my battery?

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.

How can I tell the amperage of my alternator?

Look for a diagram under or near your fuse box cover. It will have individual amperage numbers (sometimes along with volts) already set by the manufacturer. Add up those numbers to find what amperage your alternator needs to feed the car’s electrical system. Verify this number with the part manufacturer, if necessary.

How many amps does an alternator put into the battery?

For a battery being charged by the car’s alternator it can take an hour of driving to get it fully charged. Car batteries range from 40AH to 110AH, and alternators range from 45 amps to 200 amps.

How big of an alternator do I need for 3000 watts?

250A
3000 watt / 12V is equal to 250A. A 250A alternator is needed to keep up with it. Since your engine would have to work just as hard as any portable 3KW generator to keep up with the amplifier, you would need a large fuel tank.

Can a 100 amp alternator be used in a 200 amp car?

For example, you may have a 100 amp alternator in your vehicle and the turn signals have small wiring and will only use 10 amp of power. Upgrading to a 200 amp alternator will not affect these components. On externally regulated alternators you can still use the stock factory regulator.

Do you need a high output alternator for alt text?

What happens when I put 101 AMP on my alternator?

If you bring your load up to 101 amp, then the voltage in the system will drop below 12.8V because the extra 1 amp that is needed and not coming from the alternator will have to be stolen from the vehicle’s battery and hence the voltage will start dropping below the static battery level.
