What Should Car Battery Voltage Be? (Resting, Cranking, and Running)
A healthy 12V car battery should read 12.6V or higher at rest (engine off), 13.5V to 14.7V while the engine is running (alternator charging), and shouldn’t drop below roughly 9.6V to 10V during cranking. If your reading falls well outside these ranges, something in the battery, charging system, or connections needs attention. If you’ve searched…
