What Voltage Should a 12V Battery Read? Guide to Optimal Levels for Battery Health
A fully charged 12V battery should read between 12.6 and 12.8 volts at rest. This resting voltage shows the battery’s health. A lead-acid battery typically shows 12.7-12.8 volts, while a lithium iron phosphate battery reads 13.4-13.6 volts. Always check terminals for corrosion before taking a measurement. When assessing a 12V battery, it is crucial to … Read more
