Although, Extreme Weather Conditions Such As Freezing Temperatures Can Also Cause The Voltage To Drop And Increase The Power Requirement Of The Engine To Turn Over.

So, 11.8 volts will do nothing, and youd immediately charge the battery and up the volts to at least 12.4 volts. If the battery is below 12.6 volts, you should attempt to charge it with a battery charger. How many volt`s in a automotive battery.

A Good, Healthy Car Battery Should Have No Fewer Than 12.6 Volts.

Is 11.9 volts enough to start a car? The size of an alternator will most likely increase the set amperage, too. No, 11.8 volts is not enough to start a car even if the battery has a voltage rating of 12v as 12v is the minimum volts the particular battery should maintain to remain in a working condition.

A Fully Charged Car Battery Voltage Ranges From 13.7 To 14.7 Volts, It.

When the engine is running, this measurement should be 13.7 to 14.7 volts. Now start the car, and look for a revised voltage over 10. When the battery’s voltage drops, even a small amount, it makes a big difference in its performance.

No, 11.8 Volts Is Not Enough To Start A Car Even If The Battery Has A Voltage Rating Of 12V As 12V Is The Minimum Volts The Particular Battery Should Maintain To Remain In A Working Condition.
