That depends on the application [use] of the alternator. For automotive applications, NO, 15 Volts DC is not too much. Generally, an acceptable voltage output range for automotive applications is 13 Volts minimum to 16 volts maximum.

What are typical alternator voltages?
13-15 volts
How many volts does a dodge ram 50 alternator put out?
13-15
How many volts should the altnator put out when all accessories are on?
if the alternator is working properly it should always put out between 13 and 15 volts
What is the voltage range in a 12 volt auto alternator?
The voltage should be in the range of 13.2 to 14 or so volts. It should not go over 15 volts.
2004 jeep tj 4.0 what should alternator be putting out voltage?
13-15 volts, depends on what the computer wants.
How many volts does a 1987 dodge ram 50 alternator put out?
It should output the same voltage that any 12volt battery system outputs. Roughly between 13 and 15 volts (13.3-14.9)
How do you know when you alternator go out 2001 Chevy Malibu?
Check the output at the battery posts. With a multimeter it should be putting out between 13.5-15 volts.
Why is my 1984 Corvette alternator charging constant 16.3 volts?
The system shouldn't exceed 15 volts. If the battery tests out okay and you are mechanically inclined, you can replace just the voltage regulator inside the original 1984 alternator. A replacement regulator should cost aprox $30.
Why does an alternator not over charge the battery?
Alternators have a built in regulator that keeps the voltage at about 13.5 Volts. Depending on the load, the alternator may be putting out anywhere from just a few amps to full capacity of over 100 amps for some alternators. Batteries charge at anything over 12 volts and handle about 14 volts without any problem. You start causing problems for your battery and other parts of your electrical system when the voltage goes over about 15 volts. But then, if your regulator is working right that should never happen. The current (amps) of an alternator does not vary. if it is a 100 amp alternator, the amperage coming out is always 100 amps.
How do you test lawn mower alernator?
The first thing you need to do is charge you battery & load test it if possible, make sure all your connections are tight and clean, the battery should have 12.5 volts when it is not running (check with a multimeter) when the unit is running it should have 14-15 volts. if not you have a bad alternator or a problem with the wiring past the alternator.
How do you test the regulator is well charge the battery?
You will need a digital voltmeter. Set the voltmeter to 20 volts DC. Check it with the probes. 1. 12.68 Volts = 100% Charge2. 12.45 Volts = 75% 3. 12.24 Volts = 50%4. 12.06 Volts = 25%5. 11.89 Volts... You can also put the digital volt meter across the positive and negative terminals of the battery, while the car is running. The reading should be no less than 12.5 volts dc, and no higher than 15 volts. If it higher than 15 volts the regulator is overcharging your battery, and it will boil the fluid in the battery. Some regulators are on the chassis of the vehicle, most are built into the brush assembly of the alternator. Either change the alternator or consult your nearest auto shop for a new brush set and regulator.
Your bike battery wont start your bike once you ride it for a while?
three options, your headlight is drawing too much power, your alternator isn't putting out enough power, or your battery is shot.Leave a slow charger (like 2 amps) on the battery over night. Take the charger off the next morning, leave the bike for several hours without running it. Check the battery voltage. It should be about 12 volts. Now start the bike. It should be about 13-15 volts. Rev the engine while checking battery voltage. It should still be 13-15 volts.If the battery was not 12 volts after sitting, then it's junk, get a new one.If the voltage while the bike was running was not 13-15 then your alternator is not working. Either the regulator/rectifier is bad or the stator is bad.If the voltage was above 15 volts at any time then your regulator/rectifier is bad.If it passes all these tests, then make sure the lights are not switched to "bright." If it's not, then replace the headlight bulb, they can sometimes overdraw power.
