Is auto start/stop bad for the battery?
A. The start/stop feature of your car is designed to save fuel and lower vehicle emissions. AAA’s engineering department did some tests and found that fuel savings have been as high as five percent. Regarding extra wear and tear, so far tests have shown no significant change in battery or starter motor life.
Why do newer cars shut off at stop lights?
The concept of the stop-start system is simple. It automatically shuts off the engine when the vehicle is at rest to cut fuel use and eliminate idle emissions. It then restarts the engine automatically when the driver lifts off the brake (or puts in the clutch to select 1st gear) to get going again.
How long can car lights be on before the battery dies?
Between 30 and 90 minutes
Between 30 and 90 minutes is the range for the state of your battery. If you kill the battery, it will be unable to start the car. For several hours, it can run those lights.
Is engine start/stop bad?
The aim is to make it easier for the starter motor to do its job. “Using cheaper oils can cause more damage to your car’s engine than anything else,” he told Practical Motoring. “Operational stop-start causes no wear and tear at all; wear and tear at cold start-up is a thing, though,” he said.
Why do people hate autostart stop?
Some drivers do not like the abrupt stop/start action because it is a bit jarring at first. There are many people who dislike it because the feature has become mandatory, as in you cannot default it to off, and many people do not like being told what to do.
Does auto stop actually save gas?
Most people think the amount of fuel saved using a start-stop system is negligible, but in reality, that fuel burned while idling at a stop adds up quickly. A study by the Society of Automotive Engineers found that using start-stop can see a car’s fuel economy improve by over eight percent in heavy traffic.
What does it mean when your car shuts off at a stop?
If your car shuts off after you stop, the engine is very sensitive at idle. This can be caused by many things but is usually caused by a lean fuel mixture, causing the idle to drop too low. A faulty throttle body can also cause this.
What cars turn off when you stop?

Does Stop-Start use more fuel?
Do all new cars have start/stop technology?
Real-World Driving I drive over 100 new cars per year, and for the past year or so, 99\% of the vehicles I drive and review do have the start/stop system. Some automakers, like Ford, have committed to putting it in every vehicle it produces.
Do all new cars have stop/start technology?
Here is the good news: almost every vehicle I drive that has start/stop also has a switch to turn the system off, but some GM SUVs recently did not have a way to disable it. If you are like me and don’t like this technology, in most cases, you can turn it off.
What can cause a car to shut off while idling?
Faulty Oxygen or Mass Airflow Sensor Each relays specific information to the ECM (Engine Control Module). Then your engine might not receive enough air, which it needs to power itself. When there’s a lack of air, it leads to a lack of power, which can cause your car to stall while idling.
How does the start-stop battery work?
The start-stop battery has a double load The case is different for cars with start-stop technology. During a journey through the town, the battery is subjected to a series of start and stop periods.
What happens to a car battery when stationary at traffic lights?
If the car is stationary at traffic lights with the engine stopped, electrical consumers such as lights, windshield wipers, radio or displays still need power. The load is increased by continuous discharge and charging. In particular, short journeys present a challenge for the battery.
What is automatic stop/start on a car?
As the name implies, automatic stop/start shuts off the engine instead of it idling at a stop and then rapidly restarts the engine when you want to drive away. If you do a lot of stop-and-go driving, you’re reducing emissions and saving fuel by not idling for extended periods.
What happens if you put the wrong battery in a car?
If an incorrect battery is installed in the vehicle or is not correctly registered, this can result in premature battery deterioration and another breakdown. For this reason, only EFB or AGM batteries should be installed in vehicles with automatic stop-start systems.
