Because the battery may have a defect with these measured values and must be replaced.

Values above 14 or below 11.5 volts require an expert assessment of the condition of the car battery. checking the voltage, usually results in values of approx.

Successful testing of the car battery, i.e. Before the test, the multimeter is set to the voltage range of the battery and connected to its plus and minus poles. The voltage of the battery on your Ford Expedition can be measured precisely with a multimeter. Ford Expedition 4th generation battery location Test 12v battery A new battery only develops its full capacity over time. If a new car battery has been installed, the battery may not have yet reached its full capacity. A test can be done to measure the voltage between the battery poles, check the acid level and assess the condition of the starter battery. Investigating more closely and doing a battery voltage test will clarify whether the starting problem is due to the battery. If your Expedition’s engine won’t crank or cranks very slowly, then the most likely culprit is a weak or dead 12v battery.
