The function of auxiliary batteries

Model: (Various brands) Various
Part: Battery

Video tutorial

In this video, we are explained in detail what the function of an auxiliary battery is. Not always the main battery is sufficient to power all the devices on modern cars; therefore, the auxiliary battery is not secondary to the main battery, but is an important reserve of energy; for example, when we are stopped at a traffic light, the main battery will take care of starting the car when the light turns green, but it is the auxiliary battery that keeps all the auxiliary devices of the car on, whether they are for comfort, safety, or infotainment.

It is important to check the efficiency of the auxiliary battery, which, if not sufficiently charged, may require the continuous intervention of the alternator, increasing fuel consumption.

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
