Can I put a higher amp alternator on my car?
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.
Is a bigger amp alternator better?
If you’re worried about a high amp alternator providing too much power to your ECU, or any other component in your electrical system, you don’t need to. The amperage rating on an alternator is basically just the amount of current that the unit is capable of putting out, not the amount it always puts out.
How many amps should my alternator be?
The amp rating of the alternator is matched to the vehicle’s electrical system. Older vehicles with fewer accessories may only need a 70- or 80-amp alternator, while a newer vehicle with lots of electronics and accessories may need a 120- to 160-amp alternator.
Do you need a bigger alternator for a bigger battery?
No the alternator is used to charge the battery, and to charge 12V batteries the voltage applied is about 14V. It doesn’t matter how big the battery is, that is just the duration of energy storage.
Will a higher amp battery damage my car?
For city driving it’s good to have a bigger capacity battery. The extra amp/hr capacity will act as reserve. Most of the new battery are dry charge ( 100% Charge) once installed it can be used instantly. There is no side effect at all , even yr alternator will not be subjected to working overtime.
Why would I need a bigger alternator?
You’re able to reduce the depth of a battery’s discharge—also known as cycling. That’s because an oversized alternator produces more output at lower speeds, including idle. That increased output prevents the battery from having to help supply the load—and this keeps it at a more ideal state of charge.
Is a 250 amp alternator good?
A 250 or 300 ampere aftermarket high output alternator should provide enough power for all your car’s systems and your high-powered stereo too.
How do I find the right alternator for my car?
If for any reason you cannot find your alternator by entering your vehicle’s year, make and model, you can find the best alternator for your vehicle by its Original Equipment Manufacturer (OEM) number. The OEM part number can be found directly on the part itself.
What should a 12 volt alternator put out?
A good alternator should put out between **13.5-14.5 volts. Stress test the alternator – Place a load on the alternator by turning on the headlights, the radio and the air conditioning. The voltage should remain high with these circuits on.
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.
Is it OK to use a higher amp battery?
In short, using batteries with extra energy capacity will not harm your device, but would, instead, power the device for a longer time (all other considerations unchanged).
What does upgrading your alternator do?
High output alternator The battery starts the engine, but the alternator takes over when the motor starts to turn. If your sound system demands more power than your stock alternator can supply, then you will benefit by upgrading to a higher output alternator.
How do I choose the right alternator?
How many amps does a typical car alternator produce?
The output of the alternator ranges from 40 Amp up to 120 Amp. For high-amp alternator, it can generate up to 300 Amp. Commercialized alternator is usually 12 V. For some systems, especially for high power system, the alternator varies from 24 V up to 48 V.
What size alternator do I need for 2000 watt amp?
To figure out how much capacity or amperage the alternator must deliver, determine how much extra power the audio system demands on top of the current system. For example, if you installed a 2,000-watt amp, assuming a nominal voltage of 13.5V, you’d add roughly 150 amps of demand to the electrical system.
Is 14.7 volts too high for alternator?
To fully charge in reasonable times, alternator output must be 14.2 V to 14.5 V as measured right across the battery posts. Above 14.5 volts charging voltage, batteries have a greatly increased tendency to release excessive acidic vapors, hydrogen gas, and to corrode things around the battery.
