What is the normal voltage for a car battery
Alternators: Low Voltage To Battery - UnderhoodService

I've got a question for you. - SparkFun Electronics
Do not have a discharged or other battery to hook it to and then check voltage dc.Depending on the type of battery, (liquid, gel), and the age of the battery, 13.4 - 13.8 Volts is appropriate as a float voltage.The voltage regulator contained in this the system supplies an average voltage amount of between 13.8 to 14.4 volts. The voltage provided to the car battery decreases as the battery recharges.Testing the capacity of the battery with a voltmeter is more difficult.When a battery is near fully charged the alternator will cease to put.Normally a minimum of a five watt panel is required for an average car battery.While wet cells are stated to have 100% SOC at 12.7v, it is much harder to determine what 100% SOC is for an AGM battery.A car alternator needs to be putting out at least 13-14 volts (ideally between 13.8 and 14.2 volts) to effectively charge a 12 volt car battery.
What is the proper voltage for a fully charged car battery
Batteries are rated in amp-hours, describing how many amps the battery will deliver over a set period of time.For example a 12 Volt battery is made of 6 cells and has a Float voltage of about 12V.
What would make my voltage gauge read low when battery is
By the time voltage drops to 12.7, you are drawing amperage out of the battery, so any increase in amperage output after the voltage drops to 13.8 will be considered unusable.What current is a car battery - wiki.answers.com
An automotive battery is a rechargeable battery that supplies electrical current to a motor vehicle.SOLVED: battery voltage what is the normal battery voltage
charger - Is 15V too high for a standard car battery
How to Test a Car Alternator - Today I Found Out
How to Determine Golf Cart Voltage (36V or 48V): 1) Lift up your golf cart seat to locate the battery compartment. 2) Count the number of holes on a battery.The typical charging voltage is between 2.15 volts per cell (12.9 volts for a 12V 6 cell battery) and 2.35 volts per cell (14.1 volts for a 12V 6 cell battery.The few references I have located are split on the issues.some say 12.8v others say 12.85v and still others state 12.9v is required to have 100% SOC.What should the resting voltage of a 12v. car battery be, 2 hours after driving the car 8 miles.Just now: Checking the output voltage on the charger, am getting 10.7 volts on either setting.

Why Does My Car Battery Discharge Overnight or When Parked

They are now 12.2 V. When I started the truck the voltage went to 14.3.As you increase the voltage to get faster charging, the voltage to avoid is the gassing voltage, which limits how high the voltage can go before undesirable chemical reactions take place.Some older cars have -12v systems, or 6 volt systems, and there is a push to move new cars to 36 volt systems.
Note: On Cycle Electric Inc. low volt models normal operating voltage is 13.8. It will be necessary to drag the system voltage down below 13.8 to perform this test.
Car and Deep Cycle Battery Frequently Asked Questions (FAQ


Alternator-Voltage-drop-Testing - Gonzo's Tool Box
An electric-vehicle battery (EVB) or traction battery is a battery used to power the propulsion of battery electric vehicles (BEVs).When my car voltage was dropped to 12 volts when I was driving, I just turn on my headlights and the voltage went back up to 14.23 volts. Since the headlights was using up energy, the system started charging again and the voltage went back up to 14.23 volts. I will observe my car the next few weeks and see if my theory is correct.
Testing Diagnosing a car battery is a breeze, but you will need a piece of equipment called a multimeter.

How to Stop Car Battery Drains - Popular Mechanics
When system voltage is below the setting of the voltage regulator, then the regulator causes the alternator to produce power until voltage reaches the maximum setting of the regulator.
One way is to test the voltage of the battery under the load, for example, with the headlights on.
