Your car won't start because your starter battery dies? We will help you to help yourself so that you can eliminate this annoyance quickly and be on the road again soon. We also explain the causes of dead car batteries and how to eliminate them.
Car Battery Dies After Sitting A Few Days In Cold Weather
You can easily tell that your car battery is dead. Most of the time, you will notice an empty starter battery when you start your engine. If you turn the ignition key and can only hear weak or no noise from your starter, this may be an indication of a dead battery.
Similar symptoms can, however, also arise from a defective starter, a broken ignition lock, or damaged cable connections. If your starter battery is very deeply discharged, other electrical systems from the interior lighting to the electronic central locking system may fail.
The cause of the unwanted discharge of your vehicle battery is leakage currents due to defective cables or electrical systems that continued to run when the engine was switched off (e.g. the vehicle headlights).
In addition, the starter battery itself may be defective or it may not even be charged sufficiently due to a defective alternator or cable. It should also be mentioned that these problems occur more frequently in the cold autumn and winter months because the low temperatures put additional strain on your starter battery.
Is it normal for a car battery to die after sitting for a week?
Yes, it is normal to die your car battery after sitting for a week as there are several components available in the car such as security alarms, computers, clocks – These all are draw power from the vehicle continuously even when the car is turned off.
However, there are several ways to test your car battery. If you have a modern charger at hand, you can usually use it to detect a battery defect. First of all, you should fully charge your empty starter battery. If your vehicle still cannot be started, there is another cause (ignition lock, cable, or starter) or your battery is so badly damaged that it must be replaced.
Another possibility is to determine the voltage reached by the starter battery with the help of a simple multimeter. To do this, however, you must first start your car.
In the next section, we will explain to you how this can be done with the help of a jump starter (because you do not have a suitable charger at hand). Then drive your car for a few kilometers or let it charge the battery for about 30 minutes while idling. Then leave your car for a few hours and then measure the applied battery voltage. This should be in the range of 12.4 to 12.7 V. If this is not the case, either your battery is weak (due to age or due to an incorrect charging voltage) or there is a consumer or leakage current in your onboard network.
Why does your car battery die after sitting for a few days?
There are several common reasons your car battery dies repeatedly include charging problems, persistent electrical drain, corroded or lose battery connections, and also even some extreme weather. Then, if you are wondering how to start a car with a dead battery, here we have given all the essential information.
First of all, you need the right equipment. In other words, suitable jump leads and a vehicle with an alternator that has sufficient power to provide your vehicle with sufficient power. The rule of thumb is that larger / more powerful engines or diesel engines are equipped with alternators with a higher rated power.
How can you jump-start a vehicle with an empty battery?
The first thing to do is to start the engine of the vehicle providing the electricity. Then connect the two positive poles of the battery with the red starter cable. It is best to connect the cable to the receiver battery first.
Connect one end of the other cable (usually black) to a ground point on your engine or your body on the vehicle receiving the power. This should be as far away from the battery as possible to avoid oxyhydrogen explosions.
In the next step, connect the other end of the black starter cable to the negative pole of the donor battery. Now, wait briefly so that the receiver battery can be charged a little. Then try to start your engine. If this does not work within 10 seconds, you should wait a little longer. After your vehicle is running, disconnect all connections in the opposite order. Drive your car for about 30 minutes, preferably overland, to prepare your battery for the next engine start.
Frequently Asked Questions:
Q. Can you drive with an empty car battery? How long do you have to drive to charge an empty starter battery?
A.?If you can start your engine for example by jump-starting, as explained above, it is not a problem to drive with this empty battery. On the contrary: in this way you can ensure that your alternator can recharge the empty starter battery.
How long you have to drive depends on the distance you drive, the power of the alternator, and the capacity of your battery. As a rule, however, a drive of around 30 minutes should be enough to charge an empty starter battery to such an extent that you can start your engine again without a jump start.
Q. How long does it take to charge an empty starter battery using a charger?
A.Again, this depends on the battery capacity, but also your charger. However, modern chargers can automatically switch to trickle charging as soon as the vehicle battery is fully charged. This prevents overloading.
Diagnosing your vehicle battery is not difficult. If your car is sitting for a longer period, it is advisable to purchase a good charger. In this way, you ensure that your starter battery is properly cared for so that it never runs out of power.
