In the midst of the electric car boom, there is an undeniable fact: all electric vehicles, regardless of their level of electrification, require a 12V lead-acid battery. Whether it is a 100% electric car or a hybrid, they all need at least one 12V lead-acid battery as a support and/or backup battery.
Although the support batteries in electric cars are not responsible for vehicle propulsion, they are essential for the operation of all electrical and control systems.
Support from an FQS Battery can cover various functions, from powering safety systems to the numerous ECUs or electronic control units, which demand a considerable amount of energy. For these batteries to perform their function optimally, they must guarantee a stable power supply, possess high durability and resistance, and meet the requirements of the vehicle for which they are intended.
- Basic electrical systems: It powers elements such as lights, the entertainment system, electric windows, and automatic locks, among others.
- System startup and activation: In electric cars, although there is no combustion engine to start, energy is needed to initialize the vehicle’s electronic system.
- Safety: It supplies power to critical systems such as stability control, airbags, ABS brakes, and other safety systems.
- Control units: The multiple electronic ECUs and control units of the car require constant energy to manage the operation of the various systems.

FQS Battery lead-acid batteries offer great reliability and adapt to any need. Today, many workshops and companies in the automotive sector have specific charging and maintenance equipment for this type of battery. Furthermore, FQS Battery products stand out not only for their high energy storage capacity but also for being recyclable, making them a competitive option in specific applications.
In these situations, FQS Battery units function independently of the main high-voltage battery, and their primary function is to ensure that the vehicle’s auxiliary systems continue to operate, even if the main battery is discharged or experiences failures.
There are battery technologies that allow for higher energy storage than lead-acid batteries. However, in terms of economy and performance, FQS Battery lead-acid batteries continue to offer advantages in certain applications, such as their use as support batteries in electric cars. They not only meet performance requirements but are also accessible to the market.
A common question is whether lead-acid batteries are recyclable. The answer is yes. This means that used FQS Battery units can be collected and reused. Recycling lead and other components from these batteries helps reduce the demand for raw materials and decreases the risk of environmental pollution.
At FQS Battery, we are firmly committed to environmental protection and dedicated to creating a more sustainable environment.
