What causes a dead battery? 9 important reasons

When you're dealing with a dead battery, you're most likely having one of the following problems:

1.    Parasitic battery draw

The person tick battery draw refers to the situation where your vehicle's battery continues to drain even after you turn off the engine. This is not a rare situation because it can happen due to a problem with the wiring or the connections that might keep the electric components drawing battery charge and failed to shut down.

The personal battery draw is not something that will drain the battery completely in a short time. In other words, it is the type of battery drain that continues to happen over a long time which means that if you don't detect it immediately and get it to fix, you'll end up with a dead car battery.

2.    A malfunctioning alternator

There's a very common misconception that the vehicle's battery is responsible for charging all electric components as the engine is running. However, the battery is only responsible for producing the electric charge to get the engine started. Once the engine starts, the alternator takes over and continues providing the electric charge for all electric components by utilizing the engine power.

There are many common situations where the alternator goes bad when the engine switches to rely on the battery. This is because the charger looks at the components for a short time. Since the battery is not designed to support all these little components, it is easy that the battery will drain completely in no time, and the next time you try to start the engine, it doesn't work.

3.    A faulty charger

It might sound a little bit weird to many more readers that the battery charger might do the exact opposite job. Many of us rely on the charger to keep our batteries charged, especially if we leave the vehicle for extended times. However, if the charger is not of good quality, it can easily continue charging the battery until it tops it off.

While many chargers are equipped with the feature to stop charging the battery once it exceeds the specified threshold, many faulty chargers do not. Therefore, a faulty order can continue supplying the electric charge and cause your battery to get completely damaged.

4.    Electric components turned on

Another extremely common situation that most of us might have gotten involved in at least once is getting elected components turned on. For example, have you ever gotten off your vehicle and slipped overnight to discover that your battery is dead because you left the headlights turned on in the morning? Sounds familiar, right?

Therefore, once you deal with a dead battery, look at the electric components and check whether you forgot the headlights or probably the radio and sometimes other specific electric components that could gradually drain the vehicle's battery.

5.    Problematic charging system

When you start the engine, it withdraws a significant amount of energy from your battery. Then the battery relies on the alternator and on the engine to get it to charge again. If there's any problem with the charging system in your vehicle, it can be extremely hard to recharge the battery, and that's when you deal with a dead battery.

6.    Expired battery

Yes, the batteries have expiration dates here; therefore, if you were battery approaches three to five years from its lifetime, it might be the time now to install a new one. But, first, take a look at your back battery's expiration date and check whether it's approaching the end of its lifetime. If that's the case, consider installing a new one because you won't have any other solution.

7.    Faulty battery cables

Since the battery cables are responsible for allowing the battery current to run back and forth from end to battery, recharging the battery becomes a very complicated job when these cables are not in good condition.

Therefore, you must take a closer look at the battery terminals and cables to check for any signs of corrosion or rust. If that's the case, you can easily clean those up but do not do so if you notice any signs of cracks or damages because this might lead to risks of electric shocks.

8.    Shorter trips

In general, most automotive experts recommend against taking your vehicle for any short trips. In other words, if you're planning to take a 5 to 10 minutes trip, try combining your errands and newer trips, so you don't deal with these situations. While a dead battery is a very common outcome of driving your vehicle continuously on shorter trips, you can also deal with significant damages that might target one of the core components, which is your vehicle's engine.

When it gets extremely cold or hot, the battery's efficiency is impacted, and you will notice a significant reduction in your vehicle's battery as the temperature becomes more extreme. In some scenarios, the battery can get completely dead just because the weather is very cold outside.

It is also important to keep both clams away from each other to prevent safety issues.

When connecting the terminals, make sure that you first connect the red clamp to the dead battery and the second red clamp to the charged battery. Then, connect the black or negative terminal to the charged battery and the other side of the black terminal to the bare metal. Once you follow the right steps, you can start the charged vehicle and then start your vehicle with the dead battery.

Note that it takes about 10 minutes for your dead battery to get going, and once it reaches that point, you will immediately notice that you can crank the engine now.
