What is a normal car battery voltage? Confidence votes 1.7K. Assuming we're talking about the `usual' 12 volt car battery' the resting voltage should be around 11 to 11.5 volts. Under charge it's as high as 15 volts as supplied from the alternator,and most cars won't start if the voltage is under 10.5 to 11.5 volts. The term `12 volt battery' is what's referred to as, `nominal' or `in name only' as a general reference and not meant to be an accurate description.

Voltage A common voltage for flashlight batteries is 1.5 volts (DC). A common voltage for automobile batteries is 12 volts (DC). Common voltages supplied by power companies to consumers are 110 to 120 volts (AC) and 220 to 240 volts (AC). The voltage in electric power transmission lines used to distribute electricity from power stations can be several hundred times greater than consumer voltages, typically 110 to 1200 kV (AC).

How many Volts, Watts, and Amps are in the Average Car Battery? Rating Newest Oldest. Best Answer: Most car batteries are called 12 volt, although when running, can go as high as 14 volts. But the battery is still called a 12 volt system. Amps are the driving force, and battery amperage can be as low as 200 amps for small cars, to maybe 1000 amps, for larger vehicles.mps are the driving force, and battery amperage can be as low as 200 amps for small cars, to maybe 1000 amps, for larger vehicles.

Diagnosing the Battery, Charging, & Ignition System The best way to check battery charge is with a digital voltmeter. A fully charged battery should read 12.65 volts. A reading of 12.45 volts equals about a 75% charge and is good enough for further testing. Anything less means the battery is low and needs to be recharged.

- That's why a simple voltage check of a multicell wet battery doesn't tell you much, unless one of the cells is bad, which a voltage check can turn up. What really matters, in terms of cranking power in a car, is the total current flow available, aka the amperage, which can only be checked under load. Here's a quick thought experiment that may help you to understand... if you stacked up 8 AAA batteries at 1 1/2 volts each, that would total 12 volts.

- Video Transcript: Here we have a relatively brand new car battery, less than 1 year old. It should still be capable of starting a car but it was unfortunately left in a discharged state for too long. When we test the dead car battery with a multimeter, we get a reading of 6.8 Volts. Since this is a car battery it should have a reading within the 12 volt range. Because the voltage has dropped so low, a normal car battery charger will not recognize it as a 12 volt battery.

Electric Current from  a Car Battery In order to start a car the battery must supply 100 to 200 amps of current over a short period of time. This can become very difficult during the winter. The chemicals in the battery can become too cold to stir up the power necessary to start the car motor.

Automotive battery While the engine is running, most of the power is provided by the alternator, which includes a voltage regulator to keep the output between 13.5 and 14.5 V. Modern SLI batteries are lead-acid type and provide 12.6 volts of direct current, nominally 12 V. The battery is actually six cells connected serially.

Car battery voltage 12 volts is the normal car battery voltage in today’s vehicle and each of the battery has 6 cells with a voltage of 2.1. A fully charged car battery has 12.6 volts. There is a very big difference when a car battery voltage drops even a small amount of voltage.

- A: A basic car battery charger usually charges at 2 amperes. On average, car batteries hold 48 ampere-hours, so it typically takes a full day to charge a car battery. However, there are other car battery charging solutions that offer up to 10 amperes.

- Much less than 14.2 at a fast idle is bad wiring, bad alternator or regulator, or a bad connection or fuse link. When running at a normal slow cruising engine RPM, the voltage across the battery terminals should stay over 14.3 volts even with full load, like lights, heater blower, and everything else, running.

Car battery voltage 12 volts is the standard automotive battery in today’s vehicle and each of the battery has 6 cells with a voltage of 2.1. A fully charged car battery has 12.6 volts. There is a very big difference when a car battery drops even a small amount of voltage. When a car drops, for instance, from 12.6 to 12.0, there will be 75% difference. Its power drops from 100% to 25%. At 12.4 volts, a car battery is 75% charged while at 12.2 volts its 50% charged.

- 12 volts nominal.   A 12 volt car lead-acid battery will measure about 12.2 at full charge and no load. Car charging systems usually keep the voltage around 14 when the car … is running, though it might drop down if accessories are in use (lights, heater fan, wipers).2.0 at 25% charge. With the engine running you should get a reading of between 13.5 & 15.5 volts if the alternator is working properly. 12VDC for most cars or 24VDC for some trucks or large vehcles. A fully charged 12 volt auto battery will read 12.6 volts with a digital volt meter.

How many Volts, Watts, and Amps are in the Average Car Battery? A 550 amphour battery would only have 250 amps at 0 degrees temperature. Watts are amount of power used, and is figured by mulitplying the volts times the amps. So if a car is using 5 amps, at 12 volts, to run the headlights, it is using 60 watts of power. (5 x 12). But most people think of batteries as amps and volts only, hardly ever think of watts. Headlights are rated at watts, such as high beam 55 watts, low beam 35 watts.

Alternator Home Page The amount of energy required to run a cars electrical system today is about 3 times what it was in earlier cars. In the 1970's the typical maximum power output of an alternator for a fully loaded car was rated at about 55 to 60 amps.Today the typical maximum output rating is approaching 150-160 amps even though the alternators themselves are only slightly physically larger than their predecessors.he amount of energy required to run a cars electrical system today is about 3 times what it was in earlier cars.

Tenosynovitis and Tendonitis in multiple joints, what can cause this? The standard car battery in today's vehicles are rated at 12 volts. Each battery has six cells which are 2.1 volts each. A car battery is considered fully charged at 12.6 volts. When a battery drops voltage, even by a small amount, it makes a big difference. For instance, when a battery drops from 12.6 to 12.0 volts, its power drops from 100% to 25%! At 12.4 volts, a car battery is only 75% charged. At 12.2 volts, it's 50% charged.

What is a Charging System? A VOLTAGE REGULATOR regulates the charging voltage that the alternator produces, keeping it between 13.5 and 14.5 volts to protect the electrical components throughout the vehicle. There is also a system to warn the driver if something is not right with the charging system.

How to Change a Car Battery Finally, you should check the alternator. Some cars also have a battery meter, with the engine running, the alternator usually maintains a charge close to 13.8 – 14.2 volts in a properly functioning charging system. The battery should have 12.4 – 12.8 volts with the engine off, and with no accessory load.

- Today I replaced my car alternator with a new one. I then checked the voltage when the car was idle and it was 13.5 volts and when I turned on the AC and radio it was 13.4 volts. I read on the internet that the volts should be 14.2 when idle.

- 1.2V per NiMH and NiCad cell. 2.1V per lead-acid cell (car batteries are 6-cell (12.6V) and some golf carts are 3-cell (6.3V)) Finally, multiply the voltage (V) by the amp-hour (Ah) rating of the battery/pack to get watt-hours (Wh) and then compare. For example, the Switch 8 Solar Recharger is 3.6V and 2.2Ah (2200 mAh) By multiplying those two together you get 7.92W.
