![]() Unplug your phone too, since every little volt counts. To eke out every minute of charge, turn off as many electronics as you can: radio, air conditioning, heated seats, even the headlights if it's daytime. Once you turn the engine off, it might not come back on again. Use whatever charge is remaining in the battery to get somewhere safe, either an auto repair shop or your home. If the battery isn't being charged, the electrical systems will start to fail. If there was enough juice for you to start the car, then you can safely drive the car on however much charge is remaining, but it won't last long - maybe 30 to 60 minutes max. Either way, it's something you want to check out. It could also mean there is a minor problem with the battery like corrosion. If it stays on while the car is running, it probably means there's something wrong with the alternator. The battery light comes on when you start your car, and it might linger for a second or two, but it usually turns off pretty quickly. So, the light is telling you "your alternator is not properly charging." It's not telling you "your battery is bad or needs to be replaced immediately." You don't have enough information yet. It looks like a little battery, or sometimes it says "Battery." A simple circuit looks at the voltage that the alternator is producing and turns the battery light on if that voltage is low. Also, make sure you are a member of our exclusive 91Wheels Telegram group where we bring you all the latest updates related to the Indian Automotive Industry.Because your car is so dependent on the battery, any car with a combustion engine and a 12-volt battery has a light on the dashboard that warns you if the recharging system fails. Hope we gave you an insight as to what would be the reason causing to light up the low indicator on the display. This can lead to popping up of low battery indicator. The emergence of any fault in the alternator can lead to incomplete recharging of battery, which will eventually lead to the faster discharge of the battery. This will eventually disturb the flow of power to the electrical components, which will trigger the warning in the instrument console.įaulty alternator Like the battery of your car, the alternator too is subjected to wear and tear, and can die down after a certain period of time. This battery cable can loosen up after your car hits a big pothole or lethargy in the reinstallation of battery or its wiring.įaulty ground wiring When the negative cable of your battery suffers a fault, the ground wire connected to the negative terminal will too get affected by it. Loose wiring If the battery cable is not tightened up appropriately, the charge will not be able to flow and complete the transfer of charge. This corrosion can cause hindrance to the flow of charge through terminals, resulting in not enough charge reaching the alternator, thus signaled via low battery indicator. The battery has a life of almost 3-4 years when its functioning in the car, and it has the tendency of signalling you about its deteriorating health through the low battery indicator.Ĭorroded battery terminals After a certain duration of time, the terminals of the battery are subjected to corrosion in the form of a white powdery kind of substance on them. Weakening battery Obviously, this has to be the most obvious reason on this list. Easy enough to get the battery and alternator tested. However, if there is something wrong with the battery of your car, you will be signalled by your car through the low battery indicator in your cars instrument console.įollowing are the various reasons which can lead to the glowing of low battery indicator in your car:- Could be, but for most vehicles (not necessarily true for smart) the red light typically comes on when the battery voltage is greater than the alternator output voltage. The health of the battery has to be perfect not only for the performance of various electrical functions of your car, but also for other systems like the functioning of ECU and ignition. The charge in your battery can reduce due to a number of functions. The low battery indicator in your car lightens up when it detects the deficiency in the charge level in your battery. ![]()
