Does Low Battery in Car Gets Changed by Engine Running?
When your car battery is low, you may be wondering if running the engine will help to charge it. The answer is yes, but only to a certain extent.
The alternator in your car is responsible for charging the battery. When the engine is running, the alternator generates electricity that flows into the battery and recharges it.
However, if your battery is completely dead, running the engine will not be enough to charge it. You will need to use a battery charger to jump-start the car.
Even if your battery is not completely dead, running the engine for a short period of time will only charge it to a certain extent. If you need to drive a long distance, you may need to stop and let the engine run for a while to keep the battery charged.
How Long Does it Take to Charge a Car Battery by Running the Engine?
The amount of time it takes to charge a car battery by running the engine depends on the following factors:
- The size of the battery
- The condition of the battery
- The speed of the engine
- The load on the electrical system
In general, it takes about 30 minutes to charge a car battery by running the engine at idle speed.
