A dead battery can happen to anyone. No one is too conscious, and no man is too careless when it comes to having a dead battery. This is because many things could have led to it aside from not charging it.
The worst nightmare of any driver is trying to start the car probably on a Monday morning, and it won’t start. I bet nothing is more frustrating than this.
The curiosity about what could have happened to the car is not as tedious as the stress of jumping buses or getting late to work. If this happens to you, let your mind be at peace, it is most likely to be caused by a dead battery. However, even after knowing that a dead battery has caused this problem, it would not automatically solve it.
You are most likely to experience that unprecedented breakdown again because the battery is probably not full even when you charged it. This begs for the question: “How long does it take to charge a dead car battery?” And how to determine when it’s time to replace your battery?
Affirming the specific hours or minutes it will take to charge a dead battery might not be possible. This is because several factors would determine that. We will highlight some factors that could determine how fast or slow your dead car battery will charge for better understanding.
How to determine how long does it take to charge a dead car battery?
The Type Of Charger Used For Charging
To a large extent, the type of charger used will determine whether or not the charging will be fast. The output of a 1-amp float charger is relatively low to the high-boost power charger. This means that the high boost power charger is most likely to charge a dead car battery faster due to its high output. Charging with a high-boost power charger will take between three to four hours before the dead battery can be completely charged.
Condition and Type of Battery
The condition of the battery will also determine how long does it take to charge a dead car battery. This widely depends on the functionality and years of use. If the battery is still in good shape, it can charge faster. Also, the type of battery determines how quickly it will charge. The number of Amps the battery is made of is a benchmark to answer how long it will charge when it is entirely dead.
For the record, most automotive batteries are up to 48 amps. Technically, identifying the number of amps that a battery is made of and the type of charger that is used has made the question much easier to answer. If you use a 1-amp charger to charge a 48 amps battery, you need no soothsayer to tell you that it will take 48 hours to completely charge a dead battery.
However, if you are using a 2-amps charger, you will have to wait for about 24 hours to fully charge the battery. Nonetheless, the good thing is that you do not necessarily need to charge the battery completely before you can use your car. You only need to have a certain number of voltage to keep the car running.
How Dead Is The Battery?
It is important to note that batteries are built differently, and each has its functionality. Also, the batteries are not dead the same way. Few things will determine how long does it take to charge a dead car Battery. For instance, if you have a dead battery that still has two volts and another dead battery with five volts, the one with two volts is expected to charge for a longer time than the one with five volts.
The duration for charging can be determined by how dead the battery is.
Having known the duration it takes for a dead car battery to charge completely, it is courteous that we identify some of the things that drain a car battery faster.

Things That Drains Car Battery
Car Headlights Not Off
One of the constant reasons many car drivers have a dead battery is car headlights that are left on. The car headlights are mechanically designed. They run on a battery, not fuel, and are wired for use only when the car is in use. That is why most modern vehicles have an automated adjustable control that switches off the car lights after a stipulated time.
However, when a car doesn’t have these features, the lights can be left on for a longer time, which drains the battery even faster.
Fault in Battery Connection
That negative and positive sign connected to the car battery has cost most drivers their precious time on an emergency day. Sometimes, the battery’s connection can become loose, and when this happens, the battery will not be able to transmit energy properly. This explains why you ignite the engine, and it is not starting.
Faulty Alternator
The car battery doesn’t get charged automatically when the car is in use. While the vehicle depends on the battery to function well, the car battery also depends on the alternator to stay charged at all times.
However, when the alternator is faulty, it becomes difficult for the battery to stay charged. The battery is not able to retrieve used power by itself except with the help of the alternator. So when the alternator stops working, the battery only serves the function of giving out power without being powered.
With this, you may experience a dead battery even while you are on the high driving at full speed.
Old Battery
No matter how efficient your car battery is, the fact remains, it can’t last forever. Many drivers don’t know the right time to change their car battery. You need not wait until the battery stops working before considering getting a new one or reconditioning it. Once you notice the battery is not working in its full capacity as it used to when you newly purchased it, you have the option of reconditioning or change it.
Conclusion
We hope we help you find the answer on your question: “How long does it take to charge a dead car battery?”. Car batteries, regardless of how good they are, can’t last forever. However, a bit of conscious maintenance from drivers can extend their lifespan. Do not wait until the car battery is completely dead before you think of charging. Meanwhile, it is advisable to use a slow charger when charging a dead battery.
