Don't Disconnect the Battery of Modern Cars Carelessly When Leaving for Eid Homecoming, Here's Why
For those planning to leave their vehicles for an extended period during Eid homecoming, there is an important reminder regarding electrical system maintenance.
Automotive expert from the Bandung Institute of Technology (ITB), Yannes Martinus Pasaribu, reminds owners of electric vehicles (EVs) and newer cars not to carelessly disconnect the battery terminal when parking for long durations.
Unlike older car models, modern vehicles have a high dependence on complex electronic systems. The habit of disconnecting the battery, which was once considered effective in preventing battery drain or short circuits, can actually pose new problems for modern cars.
“For older cars, disconnecting the battery terminal can be an option to prevent battery drain or short circuits. But, in modern cars, this action can reset various systems,” said Yannes on Wednesday (February 25).
According to Yannes, disconnecting the battery in cars with advanced electronic systems can disrupt memory settings, entertainment systems, and even the vehicle’s computer configuration. This will make it more difficult for owners when they want to use the vehicle again after the Eid homecoming period.
Specifically for electric vehicles, Yannes emphasizes that the main battery should not be removed. He explains that EVs still need a 12-volt battery to activate basic systems, such as the vehicle’s computer, door locks, and control screens.
If this supporting battery has problems, the vehicle may fail to operate even if the main battery is in good condition.
In addition to the technical aspects of the electrical system, Yannes emphasizes the importance of implementing layered security.
He advises owners to park their vehicles in a dry and flood-prone location. In addition to activating the built-in locking system, adding physical security devices such as a steering wheel lock is highly recommended.
For conventional car users, he also provides specific tips regarding the use of the handbrake. Owners are advised not to pull the handbrake too hard when parking for a long time to avoid the risk of the brakes seizing. Instead, owners can use wheel chocks on a flat surface to keep the vehicle in a safe position.
“Each type of vehicle has a different character. Owners need to understand the technology used so as not to make mistakes when leaving it for a long time,” Yannes concluded.
By understanding the technology of the vehicle used, owners can make the right preparations so that the Eid homecoming trip is more comfortable and the vehicle remains in prime condition when it is used again. (Ant/Z-1)
