Many people have mentioned the battery discharge warning. It is happening to lots of car users and they feel concerned about it. Well, this is quite annoying as you cannot say what is causing it right away.
Then, what does this discharge sign means? are there any other problems related to it?
When the battery is depleting faster than the charging speed there will be a warning signal to remind you that your battery is in trouble. It may happen that, it is not the problem with the battery, rather there are other electric devices which are making the issue.
What Does Battery Discharge Warning Mean?
The battery discharge warning indicates that your car’s battery is being depleted faster than it is being charged, implying that your automobile is about to experience electrical troubles.
This alert will appear on either your car’s screen, the infotainment system, or the information cluster.
Battery discharge can have devastating consequences, but it can also be a sign of something more serious.
Some automobiles include a Battery Saver Active feature that puts the vehicle into battery-saving mode. This will conserve the battery by turning off non-essential electrical accessories.
When the motor is turned off and your automobile is still draining energy, a battery discharge warning will appear. Sometimes, this warning sign may appear while driving, suggesting a more serious problem.
What Causes Battery Discharge?
A car battery can be drained for a variety of reasons. However, the following are the most typical issues:
Parasitic Drain: If your car’s electrical equipment or lights are left on even after the ignition is turned off, they will slowly but steadily drain the power from your battery. This is commonly referred to as a parasitic drain.
Defective charging system: If the alternator in your charging system cannot pump out adequate voltage, preferably between 13.5 and 14.5 volts, your automobile battery will fast discharge. The battery will keep draining even if the car is running in this instance.
Bad alternator diodes: The alternator might also have defective diodes, reducing the life of your battery.
Extreme weather: Your automobile battery may be destroyed if it is too hot (above 100 degrees Celsius) or too cold (below 10 degrees Fahrenheit). If you leave your automobile in either situation for an extended period, sulfate will build up, shortening the battery’s lifespan.
Old battery: A car battery’s typical lifespan is around 4-5 years, therefore it’s possible that yours is too old to retain a full charge.
Is It Bad for A Car Battery To Drain Completely?
Yes, it is. When a car battery is depleted below 90%, lead sulfate builds upon the plates, reducing the battery’s lifespan. After a dozen severe discharges, this sulfation will cover the plates, preventing your battery from holding a charge.
How Do You Fix A Battery Discharge Warning?
If you want to fix the discharge warning, you need to stop the discharge. There are a few things you may do if your automobile battery is losing its charge. You can try to remedy a battery discharge by following the steps below.
1. Examine the Electrolyte:
Checking the electrolyte levels is the first and most important step.
How many times have you forgotten to check the electrolyte levels in your battery for months? It becomes depleted, and your automobile will not start.
The reason for this is that the battery has no electrolyte to deliver current across the terminals.
The oldest method for reviving a drained battery is to jumpstart it. Plug your car into a decent battery via jump cables. If you’re lucky, the car will start, and as soon as it does, the alternator will replenish it.
3. It Should Be Recharged:
If nothing else seems to be working, try charging the battery outside. There are a variety of external DC chargers on the market. You may also take it to a battery shop and get it charged for $10-20.
4. Replace the battery:
If nothing else works, that’s the last option. You tested the electrolyte, attempted to kickstart it, and charged it. The automobile starts, but as soon as you switch off the engine, the battery is depleted. Then you’ll need to replace the battery.
Your Battery Warning light will illuminate when it’s time to replace the battery, signalling that there’s a malfunction with your electrical system.
What Car Models Have This Common Problem?
When utilizing the radio or other digital devices while stationary, Kia vehicles are known to display the battery discharge warning signal. While this is a positive thing, there is no chance to switch off the notice, which may get tiresome.
Hyundai is another renowned automobile brand that suffers from this issue. Many Hyundai models will warn you as soon as your motor is turned off and the AC is running or you are listening to the radio, according to various owners who have posted on Hyundai Forums.
BMW, Ford, Honda, and Toyota are among the other well-known automakers with this problem.
Car batteries need to be used with care and regular maintenance. Otherwise, your battery will die quite early. You should always check if the electric devices are working properly or not and keep track of the car’s system to avoid any troubles.
The warning sign will not appear if you take good care of your car and all the electric devices that use the car battery. This way, you can worry-free driving experience.
