Jesse is also the author of four eBooks on home wiring including "Residential Electrical Troubleshooting" which covers basic electrical troubleshooting in residential homes. voltage stays constant in a closed electrical circuit, but the amperage drops as it powers a load. Given the large size of its display (6.8 inches), we were surprised at its fairly low resolution, which should have helped autonomy. And if the reading stays constant while the engine is still running, you can verify that the battery is in fresh and new condition. The fundamental purpose is to check if a battery is capable of providing enough amperage to a load. It could fluctuate around 98.3, which indicates that the amperage is 100mA - enough to run the small PCB of the TV remote control. Awesome!". Charging system appears fine. Turn off the ignition and any accessories like lights or the radio in the vehicle. This compact model is significantly cheaper, smaller, and lighter, all valid reasons to purchase it if 2A is sufficient for your needs. In our case, we have the 20 Volt range battery. If you're not sure which one to use, select the higher “A” or “10A” setting to be sure you don't overload the meter. To test the starter the battery must be fully charged. Second, we will measure the current. Once the power to the circuit has been turned off, attach the red probe on the multimeter to the negative terminal of the power supply, and touch the black probes to the negative wire and turn on the circuit. If the specific gravity is between 1.225 and 1.265, the battery is ok to test. This image may not be used by other entities without the express written consent of wikiHow, Inc.

Enable Airplane Mode. However, to assure that it can supply enough current to a load; therefore, we also measure the ampere in milliampere-hour (mAh). For a different (drained) battery, the reading looks like this. Last Updated: May 29, 2020 The negative tester lead must connect to the battery's negative post and the positive tester lead to the positive post. Simplify electrical diagnosis. Car batteries can lose their charge because of weather, age or simply because the lights were left on. To check whether it is in good condition or not, connect it to a multimeter’s test probes and measure its voltage or amperage. It just works. If this is the case, you will not see a dial with the amp settings, and the meter will be labeled as “auto-ranging,” or you may see “AUTO” on the display.
