Have you ever been behind the wheel and suddenly noticed the ominous “Battery Saver Active” message on your dashboard? Understanding what this warning means can save you from potential headaches and ensure a smooth driving experience.
what does battery saver active mean on a car
Battery saver active means that your car’s battery is low on charge and the vehicle is taking measures to conserve power and prevent the battery from dying completely. This message typically appears when the battery voltage drops below a certain threshold.
To conserve power, the car may temporarily disable or reduce the functionality of certain non-essential electrical systems, such as:
- Air conditioning: The air conditioning compressor is a major power draw, so it’s often one of the first things to be shut off when battery saver mode is activated.
- Heated seats: Heated seats are another power-hungry feature that may be turned off in battery saver mode.
- Infotainment system: The infotainment system, which includes the radio, navigation system, and Bluetooth connectivity, may also be shut down or have its functionality reduced in battery saver mode.
- Interior lights: Interior lights may be dimmed or turned off completely in battery saver mode.
- Power windows: Power windows may also be affected by battery saver mode, and you may have to use the manual crank to operate them.
Compare it with your phone’s battery saver. Once the battery level is low (20%), it turns on the battery-saver mode.
This mostly happens when the system fails to charge the battery. Failing to recharge the battery can result in a dead battery, and you may end up stranded when it happens. So taking the necessary steps is mandatory.
what causes battery saver active
There are several factors that can cause the “Battery Saver Active” message to appear on your car’s dashboard. The most common causes include:
Low battery charge
This is the most common reason for battery saver mode. When the battery is low on charge, the car’s electrical system may not be getting enough power to operate all of its functions. Battery saver mode helps to conserve power and prevent the battery from dying completely.
Faulty alternator
The alternator is responsible for charging the battery. If the alternator is not working properly, it may not be able to provide enough power to the battery, which can trigger battery saver mode.
Loose or corroded battery cables
Loose or corroded battery cables can prevent the battery from receiving the power it needs, which can also cause battery saver mode to activate.
Excessive electrical load
If you are using too many electrical components at the same time, such as the air conditioning, heated seats, and infotainment system, it can overload the electrical system and trigger battery saver mode.
Extreme temperatures
Extreme cold or heat can put a strain on the battery and make it more likely to fail. This can also trigger battery saver mode.
In some cases, the “Battery Saver Active” message may appear even if the battery is not actually low on charge. This could be due to a problem with the car’s electrical system or a sensor that is providing false information to the computer.
can i drive with battery saver active
You can drive your car even if it’s in battery saver mode, but you should be careful. Battery saver mode conserves power by disabling or reducing the functionality of certain electrical systems.
This means that you may not have access to certain features, like air conditioning or the radio. The battery’s range will also be reduced, so you may not be able to drive as far. If the battery dies completely, you could be stranded on the roadside.
how long can I drive on battery saver mode
The amount of time you can drive on battery saver mode depends on a few factors, including the size and condition of your battery, the age of your car, and how many electrical components you are using.
In general, you can expect to drive for a few hours on battery saver mode before the battery dies completely. However, if you are using a lot of electrical components, such as the air conditioning or the radio, the battery may only last for an hour or two.
how to reset battery saver active
The process of resetting battery saver mode in a car can vary depending on the make and model of the vehicle. However, the general steps involved are as follows:
- Turn off your car: Make sure to switch off your vehicle completely.
- Disconnect battery: You need to disconnect both the negative and positive battery terminals for a full reset, ensuring all power systems shut down.
- Wait few minutes: Leave the battery disconnected for at least 10-15 minutes.
- Reconnect the Battery: After waiting, reattach the positive terminal first and then the negative one.
- Start car engine: Switch on your vehicle’s engine.
Note: This will typically endeavor a ‘hard reset’ of electronic systems, possibly deactivating the battery saver mode but it may erase some settings in your car system like clock or radio pre-sets. Always check your car’s instruction manual regarding ‘battery saver’ mode first as this process might differ based on make and model of your car.
