Measuring your car batteryís voltage can be a great way to determine how charged your battery might be. The ideal car battery voltage range will provide you with a relevant interval according to which you can measure precisely what the voltage says about the batteryís current charge. A perfect voltage with the engine running is between 13.7 and 14.7V. With the engine off, you should get a reading of 12.6 volts. If the battery isnít fully charged, it will diminish to 12.4V at 75%, 12V when itís only operating at 25%, and down to 11.9V when itís completely discharged. This data and the way it relates to the design of your battery should provide you with some useful insight into the functioning capacity of your car battery.
