How to test a car battery

The video tutorial explains how to measure car battery voltage using a multimeter, highlighting the importance of maintaining proper voltage levels. It discusses the voltage drop during engine start due to the starter motor's high current draw and the role of the alternator in recharging the battery and powering the car's electrical systems. The tutorial also covers the battery's function in starting the engine and the need for a jumpstart when the battery is depleted.
