Press the start button for the load test. Run the test for 10 to 15 seconds and then stop the test.A freshly charged battery will be around 13 volts. It will settle to ~12.4 volts after being disconnected from charging. If it goes below 11 volts, it's basically dead and probably damaged. That said, as the other comment says, a load test is what measures the actual capacity (how many amps it can put out) of the battery.14 Apr 2023 ... Under 12V under light load is low. I'd expect to see 12.1 at least with the ignition on with a reasonably healthy battery. Whilst age kills car ...Disconnect the negative battery cable. 5. Touch a lead to the negative battery cable terminal. Touch the other lead to the negative battery post, completing the circuit within the multimeter, which will display the amp draw. 6. Power draw should be under 50 milliamps. This will display as 0.05 amps. 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. Correct testing of the battery state by specialist workshops. Basic principles: Testing of a conventional wet cell battery: A measuring device which can only measure the state of charge of the battery is suitable to test a conventional car battery. In an ideal case, an open circuit voltage of about 12.8 V is measured …This over charging of the battery is caused by a buildup of hydrogen gases faster than the battery can dissipate. Damage to the battery has already been done and cannot be reversed. 5. Odd Smell From Your Battery.
