What does the battery light mean in your car?
Your battery light, often known as the dashboard battery indicator, is intended to alert you to any problems with the battery or charging system in your car. When the battery light is on in a car, it can mean that your battery is worn out or damaged, or that the charging system isn’t working properly. These issues frequently are accompanied by other bad battery symptoms in your car. Maybe the automobile won’t start, or maybe the ignition stutters.
The engine may make a clicking noise when you try to start it. A radio that won’t switch on and slowly opening power windows are other potential issues. When you start the car, the car battery light illuminates, and everything is well. When you turn on your car for the first time, this light should briefly appear. After a short while, the light will go off. Nonetheless, be alert if the light continues to be on while you are driving. Some symptoms of a low battery charge include power windows that are difficult to open or a stereo that won’t switch on.
Reasons why your car battery light is on
If the car battery has corroded cable terminals, poor wiring, damaged cells or plates within, or if it is dripping electrolytes, these could be the reasons why your car battery light is on.
You Are Using Too Many Accessories in The Car
Your EV can be wonderful and fun to customize. You can include a powerful system or LED lighting. These features consume a lot of energy. They will consume more energy than your alternator is able to supply. Keep in mind that the alternator also provides additional power to your battery. The auto battery will run out of power once the accessories have consumed it. After that, a glowing battery light will alert you to the system.
Poor Alternator
It’s possible that the car’s alternator is broken or dead. The battery won’t be receiving any power from it. In order to inform you of the problem, the battery light will continue to glow. There could be an imbalance in the voltage sent to your battery. The battery is destroyed by voltages that are significantly outside of or within the range. You will suffer considerably greater harm if you ignore the sign. After you verify your car’s voltage, the table below should help you determine the correct voltage.
Old or Weak Battery
If you continue to see this light each time you drive, your battery can be worn out. Most EV batteries have a lifespan of three to five years. That depends on how you manage the object. The electrodes start to fail as the battery ages. If the electrolyte is weak or old, it may leak. The battery’s power will thereafter quickly deplete. As a warning, this causes the battery light to illuminate on the dashboard while you are driving. A battery like that has no voltage.
The Battery Terminal is corroded
Battery corrosion is the worst thing that can happen to your car, according to virtually any technician or automotive professional. The incident is caused by leaking battery acid, battery moisture, and numerous other factors. Moreover, the battery will degrade in high-heat environments. On battery terminals, it produces a greenish, bluish, and whitish form. These components restrict the conductivity of power through your battery. It will be flagged as a problem by your car’s computer, and the battery lights will let you know.
Wrong Battery Terminals and Cables
Your car gets power from your battery cables. But occasionally, they may get corroded or damaged. In addition, if you don’t connect them properly, the power flow will be interrupted. In the car, the power supply becomes a concern. Moreover, an automobile fire could be started by such cables. As a result, your car will provide several cautions to deal with the problem.
Bad Alternator Pulley
This part ensures that your alternator performs well throughout extended travels. If you don’t service your car for a while, something could go wrong. Enough grease is required for the pulley to support the alternator. The pulley won’t function properly and will become noisy if there is no grease or too little of it. Such a problem limits the alternator’s ability to produce electricity. The battery lights on your automobile will alert you to the situation.
Poor Wiring
An EV includes numerous cables that allow for a steady power flow, similar to a vehicle driven by fuel. If the wires are faulty or break, the battery could be in danger. Mistakes made when the wires were connected are the cause of poor wiring. The cables could also be brittle and old. The system will alert you about this issue because the majority of EVs are intelligent. That happens via the dashboard’s battery light. If you ignore the wires, the battery may suffer damage. They may occasionally start a fire.
Look at The Temperature Gauge
This light can appear occasionally in hot weather. It appears after a long drive or when you park your automobile in the sun. The battery in your automobile will overheat and stop working. Moreover, charging issues can cause overheating. The battery light will therefore be on and blinking on the dashboard. Also, the temperature gauge will alert you.
Bad Alternator (Serpentine) Belt
Every EV must have this component to function. It spins the alternator to power the battery using the force of the engine’s crankshaft. Additionally, it controls the steering, electronics, and AC systems in your car. The consequences for the car if it breaks will be severe. The steering and accessories in your automobile won’t operate properly. Check to see if the battery light illuminates.
Blown Fuses
Though it’s hard to tell, your car might have a dead fuse. These components safeguard the electrical components of the car from a surge or failure. Yet when the fuses are overwhelmed by the current, they blow. You’ll notice a few things after the intense music has stopped. You will be alerted by the dashboard’s battery light.
Bad Ground Strap
Any electric vehicle (EV) won’t have a full power flow without a ground strap. It completes the link between the vehicle’s systems and the engine. Low voltage or a dead battery are the causes of it. If the strap is dead or insufficient, your headlights will turn off. The system will continue to notify you of this issue.
How can you tell when your car battery needs recharging or replacement?
When your vehicle’s battery needs recharging or replacement, there are a few signs and symptoms you’ll notice. These symptoms include the following:
- Electrical components not working properly
- Dull headlights
- The batteries over four to five years old
If your battery is more than 4 years old, we advise getting a new one. A battery this old might be momentarily rechargeable, but it will most certainly lose its charge again very soon. With time, older batteries deteriorate and inevitably lose their capacity to store a charge.
When charged, even worn-out batteries that need to be replaced have enough power to start an automobile. Electronic functions that aren’t operating as they should be are common indicators that your battery is nearing the end of its useful life.
The “check engine” light may occasionally come on if the battery is weak because it is unable to supply the onboard computer with enough power. A drab dashboard or interior lighting may be a sign that your battery needs to be replaced.
Another indicator is dull headlights; if you notice these, the battery might be to blame. Put the car in park or neutral and gently rev the engine; if your headlights get brighter as you rev, your battery is weak.
Don’t take any chances if your battery is starting to suffer and hasn’t been changed in a few years. Although replacing car batteries is not particularly expensive, it is worth it to avoid the stress and inconvenience of a breakdown on the road.
Can you drive with the battery light on in the car?
Driving while your car’s battery light is on is unsafe. Your car may lose power if problems with the battery or alternator that trigger the battery light exist. Your car won’t work normally under certain circumstances. You must make sure the battery is always functioning properly because it is a crucial piece of automotive equipment. Look into the problem if you’re unsure of why your battery light is on. Moreover, if the issues persist, have your automobile checked out and fixed by a professional mechanic.
In other words, while it is physically safe for you to drive with the light on, it is not safe to guarantee that you will get to your destination without a breakdown or for the other parts of the car that a weak battery, such as the alternator or electronic equipment may impact. The automobile battery light typically indicates that the battery needs to be charged since it is weak. However, the light turning on could also be the result of another electrical problem.
A closed circuit is used in the electrical system. The failure of an electrical component could result in additional expensive damages. Driving is simply not a good idea when the car’s battery light is on. Also, we advise you to always keep a set of jumper cables in your vehicle.
What should you do when the battery light appears on the dashboard?
Find a good, secure place to stop if the battery light on your automobile illuminates while you are driving. Losing your power steering could make it challenging to control your vehicle. You have a higher chance of having an accident if you completely lose power. Here’s how to reset the battery light.
- Check the alternator in your car. If it’s malfunctioning, that can be the cause of your battery’s inability to charge.
- Ensure that all of your vehicle’s lights are off. If any of them are turned on, your battery might drain.
- Try starting your automobile without the headlights on. Your battery needs to be charged if the battery light illuminates, signaling a low battery.
- You can reset the light by disconnecting the negative terminal of the battery for a short while if the battery or charging system of the automobile is working properly.
As an alternative, you might be able to continue driving for a little length of time if you are close to your home or a qualified auto mechanic can examine your vehicle. Make sure that your car’s superfluous electrical systems are all turned off. You might be able to travel a longer distance thanks to this.
