The battery warning light while driving means that the alternator is no longer charging your battery; the battery is now operating entirely on its power. It means your car is only running on battery power that will eventually run out, causing it to stop.
To avoid further battery drain, turn off your accessories if your Ford Focus battery warning light illuminates while you are driving. You are operating on battery power when the warning light comes on, which means your alternator isn’t working properly.
What Does The Alternator Do?
While driving, your Ford Focus battery is charged through the alternator. If the alternator fails, the battery can drain completely, leaving you stranded if you turn off the vehicle.
What Can I Do If My Ford Focus Battery Light Comes On?
Unless you are driving at night, ensure that all the lights, the radio, and the air conditioning are turned off. The serpentine belt of your Ford Focus may also be malfunctioning.
Pull over to a safe location if possible if you have multiple warning lights, including the battery light. In that case, the water pump was also on that belt if the dash lights indicated overheating.
In addition, if the steering becomes laborious or feels large, the serpentine belt may be the reason for the battery warning light.
Common Problems & Issues with Car Batteries
It is a common car problem to experience a dead battery. Every one of us has made mistakes, whether we forgot to turn off the lights, didn’t close the door properly, or left the radio on for too long before we started the car.
But when should you replace the battery in your Ford Focus? A Ford mechanic may recommend replacing or checking your Focus battery if you experience any of these symptoms.
Engine Cranks Slowly
The vehicle takes a long time to roll over or start than normal whenever you try to turn it over or start it.
Corrosion Or Fluid Leaks
When contrasting fluid leaks or battery fluid leaks cause excessive corrosion, the battery should be replaced. For example, your Ford Focus battery will accumulate corrosion over time, and this corrosion can be removed with a battery cleaner.
Check Engine Light
In most cases, when the battery is losing its charge, the check engine light will illuminate.
The Battery Fluid Level Is Low
Having low fluid levels indicates that the battery needs to have the charging system and battery tested.
Battery Warning Light – Why Does It Come On?
It is usually straightforward to determine why dashboard warning lights are illuminated. The cause could, however, be something more serious and expensive. Here are some things that can cause your battery light to illuminate:
Batteries Or Cables That Are Damaged
There is probably nothing more common than a failed battery to cause the battery warning light to appear. A battery may become damaged, the terminals may corrode, or the cables may become dislodged or damaged over time. As a result, the alternator will gradually lose power, and the battery will lose power as well.
Alternator Belt Broken
A belt that drives the alternator and engine coolant pump could be a serious problem since it also drives the power steering.
The alternator belt may need to be replaced if your engine warning light comes on, the car becomes difficult to steer, or your engine temperature increases.
When this happens, stop your car and call your nearby garage or breakdown service as soon as it’s safe to do so. If your alternator belt breaks while driving, you may cause serious engine damage to your vehicle.
Electricity is produced by your alternator and stored in your car’s battery. A car’s battery also provides power to things such as headlights, heaters, radios, and electric windows while it’s running.
A failing alternator drains power from your car’s battery directly, resulting in your car losing power and eventually stalling. In addition, keeping your car running at the same time requires more power than your car’s battery has stored.
If It’s The Alternator Or Battery, How Can You Tell?
Likely, your alternator is not keeping your battery charged if your engine starts but dies immediately. Jump-starting your car may keep it running, but if it can’t start again on its own, you probably have a dead battery.
What Is The Best Way To Tell If Your Ford Focus Battery Needs To Be Replaced?
Your Ford Focus battery can fail if it is slow to start after turning the key or shows signs of heavy corrosion around its cables and connectors.
If your car won’t start or your electronics work, but the key doesn’t turn, you may hear a clicking sound. Likewise, if your Ford Focus battery fails, you will notice these symptoms.
How Does A Car Battery Get Drained When It’s Off?
Car batteries may be drained by interior lights, door lights, or even bad relays when the car is off. Alternators recharge batteries while engines run, so when you’re blasting the radio on your drive to work, your battery won’t die.
What Are The Most Common Causes Of Car Battery Drain?
You may need to replace your battery if your electrical devices or lights have been left running, if there is a defective charging system or alternator, or if there are extreme weather conditions.
Ford Focus Battery Price & Cost Of Installation
The cost of your Ford Focus battery will depend on a few factors you consider when purchasing one. What is the engine size of your Ford Focus? Does your Ford need a large or a small battery?
Are you looking to purchase a battery from our dealership and install it yourself, or do you want our dealership to replace your battery? It would help if you considered these questions and more before deciding on a battery or replacement.
In addition, the price of a new battery for your Ford Focus depends on whether you plan to install it yourself or hire someone to do it for you. Because of the shrinking hood space as vehicles have become more powerful, sometimes the battery can be difficult to maintain.
Depending on the market, labor costs may increase your service bill by $20-$40 if you want a Ford-trained technician to install your battery.
When Should You Replace The Battery In Your Ford Focus?
Leaving the battery unchecked can cause your Ford Focus to put a strain on the alternator or starter when the battery is not performing at its optimal level. Your engine can run outside ideal conditions if you draw excessive power to compensate for battery loss. It will end up costing you more to fix this.
To ensure that your battery is functioning at its best, you should test it regularly for voltage drops. It is common for car batteries to carry 12 to 13 volts unless they are high-performance batteries. Therefore, there is a possibility that a faulty battery has a voltage higher than 13 volts.
The Bottom Line
Inspecting the battery for corrosion or damage requires eye protection and extreme care. If you suspect your battery may be damaged in any way, it is always recommended that you have it checked by a professional technician.
If your vehicle’s battery warning light illuminates and stays on, it could be a sign of a simple problem or an issue that could severely damage your engine.
You should never ignore a warning light, so ensure your car is checked by a trusted local garage immediately.
