If your car is giving you a warning saying “stop/start battery charging not ready”, you may be wondering what the problem is and how to fix it. Fortunately, we did some digging for you and found a solution.
Your car may say “stop/start not ready battery charge” due to a bad battery cable, bad alternator, bad battery, malfunctioning ignition module, or problem with the terminal.
You can try the following steps to resolve the issue:
Check battery and alternator
test ignition module
Take the car to a mechanic.
Whenever you see this warning message, you should identify the cause of the problem as soon as possible. Read on for detailed information on how to drive a car that says “stop/start, not ready to charge battery.”
Why does my car say “Stop/Start battery charge not ready”?
If your car’s computer displays the message “stop/start battery charging not ready”, don’t panic. It may indicate that your battery is low and needs to be recharged.
You must fully charge the energy storage system for the stop/start system to work well. However, there may be times when this system cannot be charged due to a malfunction.
As a result, the error message “stop/start battery charging is not ready” may appear. Most of the time, this message is the result of the following:
Defective battery cable
Your vehicle’s electrical system may not be working properly if the battery cables have become corroded, broken, or loose.
Corroded battery cables can lead to a variety of electrical problems. If the corrosion is severe enough, it can prevent the battery from charging. You can trigger the error message “stop/start charging battery not ready”.
Also, corroded battery connections can cause your car’s electrical system to work less efficiently, leading to issues like dimmer headlights or taillights.
faulty alternator
The alternator generates electricity to power your car’s electrical systems whenever the engine is running. This component transforms mechanical energy into electrical current through a belt driven by the motor.
The alternator keeps the lights and wipers running and charges the battery when it runs low. It also helps keep up with your car’s power demands. Alternators have a lifespan of only three to four years, much less than the average car battery.
Remember that the alternator is necessary to charge the battery. So neither the battery nor the starter will work if it fails.
The alternator may be to blame if your car “says stop/start isn’t ready to charge the battery” and the wires aren’t corroded.
faulty battery
The battery is a crucial part of your car’s electrical system. The engine will not start and the car’s electrical components will not work if the battery dies.
Most batteries have a useful life of three to five years before they need to be replaced. However, exposure to extreme weather conditions can reduce the life of a battery by up to three years.
If the battery fails (completely loses its electrical charge and stops charging), you won’t be able to use any of your car’s electrical systems. As a result, the error message “stop/start battery charging not ready” may appear.
faulty ignition module
The “stop/start not ready to charge battery” warning can appear when the ignition module is broken or malfunctioning.
As the name suggests, this component is crucial in starting the car’s engine. If the ignition doesn’t work, no matter how well charged the battery is or how good the alternator belt is, you won’t be able to start the car.
When you turn the key or press the ignition button, the battery delivers a surge of electricity to the starter motor. It then powers the vehicle when the spark plugs ignite the compressed air and fuel in the cylinders.
It is the task for which the starter is responsible, but it is very important. When the ignition and starter fail, the engine will not start and you may receive the warning “stop/start not ready to charge battery”.
terminal problems
In addition to the battery, cable, and alternator, the charging system can also be affected by the battery or alternator terminals.
Oxidized terminals, caused by exposure to battery vapors or moisture, pass very little voltage, if any. Because of this, the ESS can take a long time to load.
As a result, you will still get the “stop/start is not charging the battery” message. Since the rust is visible, you can quickly determine whether or not there is a problem with the terminals.
What to do if the car says “Stop/Start Not Ready Battery Charging”
Check battery and alternator
Before you do anything else, you should inspect the battery, alternator, and terminals to make sure they are clean and free of corrosion. If they are not, use a wire brush to clean them.
Also, make sure your wiring harness is in good condition by inspecting each wire for signs of deterioration or fraying. You should repair or replace them if necessary. If the issue is not resolved, go to the next step.
test ignition module
If the battery and alternator are not faulty, check how long your engine starts after disconnecting one spark plug wire at a time.
Then see how long you’ve been with just one plug cord attached. If it takes less than 10 seconds, it is an indication that there is a problem with your ignition module. So you should consider getting a replacement.
Take the car to a mechanic
If you can’t determine the cause of the problem and the “stop/start, battery charge not ready” message doesn’t go away, take your car to a repair shop and have it checked by a professional.
Will the “Stop/Start Not Ready Battery Charging” message go away?
Yes, he will do it. The “stop/start battery charging not ready” message should be cleared. This occurs when the battery has been charged to its maximum capacity.
When you have repaired or replaced the parts causing the problem, you should wait a few minutes for it to fully charge before using the car.
If the warning message continues to appear despite this, you may need to reboot your system to get rid of it. If the message does not go away even after restarting the vehicle for at least thirty minutes, this indicates a more complex problem with the car.
How long does it take to charge the Start/Stop battery?
The time required to charge a start/stop battery depends on many factors. Both temperature and weather influence charging time.
The start/stop battery takes at least one hour to fully charge when the outside temperature is above 59 degrees Fahrenheit. The charging process takes three to four hours when the ambient temperature is lower.
However, this may only be the case for some vehicles. The battery capacity and the model of your car will determine the duration of the charging process of your start/stop battery.
The start/stop battery charges gradually when a load is applied to it. When there is less charge, it has a better chance of charging faster.
Can a Start/Stop battery be replaced?
Yes, you can replace a car’s start/stop battery. You must replace it with a similar battery that has been approved by the car manufacturer.
Also, you should have a professional mechanic do the replacement. Professionals often have the necessary diagnostic tools to get the job done.
In conclusion
If your car says “stop/start not ready battery charge”, the warning could be due to a bad battery cable, bad alternator, bad battery, malfunctioning ignition module or terminal problem .
To fix the problem, you need to check the battery and alternator, then test the ignition module. You can take the car to a mechanic if you need help solving the problem.
