The starter motor in a car relies on the battery for power to crank and start the engine. The battery depends on the alternator to keep it charged at all times provided the engine is running.

A low battery can cause problems such as not starting the car or not being able to drive for a long time. In order to avoid these issues, make sure that you check your battery regularly and change it if necessary.
How Can You Tell if Its the Battery or Alternator?
The alternator is faulty if you can start your can but then dies after the engine is running. Almost 70 percent of the battery power is used to crank the starter motor, so, after starting, little to know power remains in the battery.
At this point, the car might start in the first instance but if you turn off the ignition and try turning it back on, it will not start. The alternator’s main function is to charge the battery and keep it charged at all times, so, if it stops working or failing, the battery would not be charged.
Watch for Better Understanding
The battery is faulty if you observe the headlights and or dashboard lights to be flickering. Another sign of a dead battery is the inability to retain energy after being charged.
Is It Safe to Drive My Car with the Battery Light on
Driving with the battery light on is not safe at all. If you are driving with low battery power, it is best to pull over and let the car charge for a while.
This is because when the car has low battery power, it will not be able to provide enough energy to start the engine or even turn on the headlights.
Can a New Car Battery Cause Electrical Problems
This is a question that comes up quite often and it’s important to know how to spot if a new battery causes electrical problems.
The most common cause of electrical problems with a new car battery is the battery being too small for the current draw of the car. If you have an old battery and you’re going to replace it, make sure that your car has enough power capacity before you buy a new one.
When buying a new car, make sure that the current draw on your battery can handle the power capacity of your vehicle. Otherwise, you might end up with electrical problems down the line.
