Is 14 Volts Too High. The battery terminal charging voltage must be less than 14.7 volts to prevent excessive gassing. With solar, particularly during winter, and deeply cycling batteries (75% to 50% state of charge), many times you need to hit the battery with much higher voltages to get it to charge quickly in the limited number of hours per day.

The battery terminal charging voltage must be less than 14.7 volts to prevent excessive gassing. At the rate you can boil water off pretty fast. The normal charging voltage on a typical application might be 13.9 to 15.1 volts at 77 degrees f.but at 20 degrees f.
6 Cells In A 12V Battery = 12.6 Volts Each Cell Can Be Charged Up To 1/2 Volt Over So 2.6 Volts Per Cell Which Is 15.6 Volts.
With solar, particularly during winter, and deeply cycling batteries (75% to 50% state of charge), many times you need to hit the battery with much higher voltages to get it to charge quickly in the limited number of hours per day. Change the battery too, the excessive voltage probabl hastened its demise. It's accompanied by a sulfur smell.
So, To Answer Your Question, Yes, 15 Volts Is Too High.
In this case the battery charging voltage is 14.61 volts with the engine at high idle. I am not sure if that same rule applies to dc, but i suspect it does. Sounds like you need a new resgulator/brush pack.
Most Listed 12 Volts Electronic Equipment Are Rated Around 14.5 Vdc Max.
The question is, will the internal regulator cut the voltage to 12.6 when the battery is fully charged. If its old school, this is pretty normal, and its time to stop charging. I operate with batteries in the 12.5 to 13.8 vdc all the time with no issues.
Charging Voltages Over 14.7 Volts Can Prematurely Dry The Battery By Boiling Out Electrolyte, And Increase Risk Of A Battery Hydrogen Gas Explosion.
For instance, a deficiency of six tenths of a volt can lead to a power loss of up to 75%. 14.8 is indeed too high. Sounds a bit high denis.
Charging Voltage Should Run Up To Around 14.5 Or So Depending Upon The Regulator.
Much less than 14.2 at a fast idle is bad wiring, bad alternator or regulator, or a bad connection or fuse link. Have a drawdown test done at autozone or wherever. 16 volts is too much.
Voltage Follower Circuit Using Op Amp . It is also commonly known as unity gain opamp amplifier or opamp buffer. These types of circuits provide better load regulation, than a simple zener diode and resistor alone. op amp Stepbystep explanation of how voltage follower from electronics.stackexchange.com A voltage follower circuit has a very high input impedance. Output voltage equivalent to the input voltage. There is no amplification of the voltage.
High Voltage Distribution Block . The revolving part is called a distributor rotor and the stationary part is called a distributor block. Availability of power on demand. 0/2/4 Gauge in 4/8/10 Gauge Out Amp Power Distribution from triple-deal.com 3 phases, neutral, earth single phase wiring: Power must be available to the consumers in any amount that they may require from time to time. However, high voltage requirements are often rare in design, which is why voltage considerations are typically ignored for voltages under 100 v.
What Is Amp Volt Watt . For instance, at 240 volts, 240 watts are equal to 1 amp. At 240 volts, 1 amp is equal to 240 watts. Watts, Amps and Volts and How To Understand Electricity from owlcation.com An ampere, or amp (a or i, for current), is the amount of current in a circuit, while voltage (v) is the strength of the current as it flows through the circuit, and watts (w) are the total electrical power released by circuit per second. Whats the difference between a volt, amp, and watt? If you have an electrical appliance using 1500 watts of power on a 120v circuit, you can use the equation current (amps) = power (watts) ÷ voltage to calculate that the draw of the electrical appliance is 1500 / 120 = 12.5 amps.
