This is because of the way lead-acid batteries discharge. This way you'll be able to measure the 'resting voltage'.A good battery will sit around 12.6 to 12.8 volts when fully charged. When a good battery is put through a load test equal to its rated CCA (cold cranking amps) its voltage will drop to around 9.6 to 10.5 volts depending on the ambient temperature. It will then shoot back up to ~12.6 volts once the load is removed. Bad Battery costco bagelsunclog toilet without plungerhow much do pharmacy technicians get paid In practice, a car battery has six cells, each of which has a typical resting voltage of 2.1 volts. Therefore, since the cells are connected in series, the total rest voltage of a fully charged battery should be at least 12.6 to 12.8 volts. The above resting voltage value is known as the open-circuit voltage. Once the car battery is exposed be careful that nothing metal touches the terminals, so don't rest any spanners or other tools on it. Using your multimeter, you want to measure DC voltage (this is indicated with a solid line and a dashed line above a letter V). Set the dial to 20.
