Despite the general name of “battery check” there is more to the procedure than just testing the battery to make sure it is in good shape. A better description of the process would be to say, “Battery test and electric system inspection with visual assessment included” but that isn’t quite as easy to say. When symptoms related to the vehicle’s electrical system arise, the battery is most likely the culprit. Issues with the alternator or wiring are less likely. Due to vehicle design, it is easiest to check the battery.
Batteries fail either because of mistreatment or because they’ve reached the end of their useful life. The battery’s useful life is a combination of actual time in years and the number of times it is used and recharged by the running engine. Immediate problems arise because once a battery is completely drained it will never fully charge again. An immediate drain can be caused by forgetting to turn off the lights, using the radio without the engine running, or the car alarm going off without being heard and turned off by the owner.
It is possible a driver may be at home and find their battery is dead when trying to turn on their car. Unfortunately, it’s more likely for the owner to be on the road and find themselves stuck because the battery is incapable of starting the vehicle. In the worst case, the battery is so far out of order it simply can’t run a charge through it, and the entire electrical system shuts down while driving down the road. Such a case usually involves problems other than the battery, but at that point, the battery will be dead and need replacement in addition to any other repairs the vehicle needs.
