Does a Car Security System Affect a Car Battery? - CarLock (2024)

The world is a dangerous place for you and for your vehicle. There are always people out there who are looking for a car or truck that’s easy to steal. Whether they want to joyride, or they want to strip the car down and sell it, or do who knows what else, criminals love stealing vehicles. Naturally, you want to make sure that you have a quality car security system that can help to keep your vehicle safe.

There are many different types of security that can be used to improve the safety and the wellbeing of your vehicle today. One of the most common questions asked about these systems is whether they are going to drain your car’s battery or not. Let’s take a closer look at some of the different types of systems for car security, see how they work, and see which ones could be draining the car battery, so you can avoid them.

Types of Car Security Systems

There are many different types of security systems for vehicles available today. Some of these will affect your batter more than others will, and some will provide your vehicle with better overall protection. Let’s get a better idea of some of the different types of car security systems that are available today.

Traditional car alarms are likely the first thing that you think about when it comes to security systems for the car. These have been in use for many years, and they will sound a loud alarm when someone tries to break into your vehicle. However, these are not as effective as they used to be. Many people today simply ignore these alarms when they hear them. They have essentially become a part of the background noise.

In addition, there are immobilizing devices that can turn off the fuses or the engine of the vehicle in case it is being stolen. While these can be helpful, they are not always the best solution for everyone. They can be more expensive to install, for example.

Of course, there are also older, simple car security systems, such as a steering wheel lock. These should never be used on their own, and they aren’t likely to stop a determined thief, but only slow them down slightly.

There are also tracking devices, such as OBD trackers, from CarLock. These systems can be a good option for those who want to have a simple and effective way of being notified whenever something is happening with their vehicle. They utilize the GPS as a means to track the vehicle, but some of the systems can also let you know when your vehicle is being moved or when vibrations are detected. Car security systems like this can let you know right away if something is happening with your vehicle, so you can contact the authorities.

Some Security Systems for Cars Will Drain the Battery

While most of the car alarms system that come from the vehicle’s manufacturer will not cause the battery to drain prematurely, that’s not always the case with aftermarket alarms. This is particularly true of alarms that have an “on” mode when the vehicle is stationary and turned off. The wiring to the alarm on these systems goes directly to the battery, and they will slowly take away energy from the battery. Eventually, this can lead to the failure of the battery.

It generally happens later in the life of a battery. The older a battery gets, the less effective it is at holding a charge. Hooking up one of these types of systems to a car with an old battery will almost assuredly lead to a dead battery.

In some cases, the alarm system might have been hooked up to the system incorrectly. This could also lead to a battery drain. Choosing low-quality systems or choosing the wrong professionals to install the car security system can be a huge problem. Don’t make the mistake of choosing a system that’s going to do more harm than good with your vehicle.

The Dangers of Draining the Car Battery

Naturally, you want to make sure that the vehicle you own is going to start in the morning when you head out to fire it up. If you have a car security system that is using a substantial amount of the car battery’s power, though, you might find that the vehicle doesn’t start. A system that puts too much stress on the battery will even mean that you have to change out the battery more often in many cases.

The last thing you need is to be unable to start your vehicle. Instead of running the risk of using a car security system that will drain the car battery, it makes more sense for you to choose an option like CarLock instead. With CarLock, you will find quite a few benefits.
