To test the cold cranking Amps keep your multimeter connected to the battery terminals and then fire up the ignition of your car. The first test with your multimeter will measure DC voltage indicated with a solid line and a dashed line above a letter V.
5 Tips on How to Test Your Car Battery DC Volt20V Setting. First and foremost ensure you have a working multimeter that has a good battery in it. For your battery to pass a load test the multimeter must read between 95 to 105 volts straight for 30 seconds when the battery is tested.
Multitesters have many uses and one of the handiest is testing common household batteries. Testing the condition of batteries isnt as simple as measuring the voltage with a meter. In this video Ill show you how to quickly determine the condition.
For example if you have a 12V battery test it using the 20V setting. Using any settings beyond that would lead to a. The INNOVA 3320 is good for this.
Other popular automotive multimeters include the INNOVA 3340 and the top of the line Fluke 88V. Take an exact voltage reading with a multimeter voltmeter or battery tester to get an exact charge reading. You can also use a multimeter or voltmeter to test your car battery.

The proper voltage for AAAAA NiCdNiMh rechargeable battery is 125 Volts To test the battery turn on your voltmeter put the voltmeter on DCV and make sure that it is far above the battery voltage on most voltmeters there is a setting 20 in the DCV area so switch your voltmeter to that setting. The battery voltage will read out on the meters display screen.
For example a fully charged AA battery should have a reading of at least 15 volts. And you can use your multimeter to test. Direct Current Gain hFE.
This setting is to test transistors and their DC gain but its mostly useless since most electricians and hobbyists will use the continuity check instead. Your multimeter might also have a dedicated setting for testing the amperage of AA AAA and 9V batteries. This setting is usually denoted with the battery symbol.
Place the red multimeter lead on the red positive battery terminal and the black multimeter lead on the black negative battery terminal. Step 3 Read the multimeter display. A reading of 124 VDC indicates a fully charged battery 122 VDC is considered 50-percent charged and any reading below 120 volts indicates a dead battery.
