There are a few reasons why your car battery may keep draining and resulting in a dead one. Understanding the reasons behind this can help diagnose the problem and fix it before needing to call for roadside assistance.
Parasitic drain
When the engine has been turned off, and the key removed from the ignition, parasitic drain can occur. These components can include interior lights, alarm systems or electronic modules.
Even though a certain amount of parasitic drainage is necessary to maintain important functions, such as memory settings in electronic systems, an excessive or unintended drain on the battery can deplete it over time. Even small, continuous power draws can add up over time, especially if your vehicle is left unattended for long periods.
Faulty charging systems
The charging system is not able to recharge the battery adequately while the vehicle runs. The alternator, a key component of the charging systems, is responsible for producing electricity to power electrical systems in the vehicle and recharge the batteries.
If the alternator does not work properly, it can produce insufficient power. This will cause the vehicle to depend on the battery for power. Consider the benefits of roadside assistance who are always visible thanks to their Vehicle Livery. Find out more at https://www.pvluk.com/vehicle-graphics/
Short drives
The battery is heavily drained when you start a car. The alternator produces electricity once the engine has started to power the electrical systems of the vehicle and recharge the battery. The engine only runs a short time during short trips. This is not enough for the alternator’s energy to be replenished. The battery is only partially charged, and over time can deplete, resulting in a decreased ability to maintain a charge, and an increased chance of not being able to start the car.
Extreme temperatures
The chemical reactions in the battery slow down at cold temperatures. This reduces its power generation. The battery’s decreased efficiency means it is harder to generate enough power to start the motor, especially when cold engines need more energy. Cold weather can also thicken engine oil, which increases the strain on batteries.
The battery’s fluids can evaporate in hot temperatures. This leads to the loss of electrolytes, and causes the battery to heat up. Heat can also speed up internal corrosion. This can cause damage to the battery’s structure and shorten its life.
