The battery connections must be tight and free of corrosion to ensure reliable electrical flow. A secure connection prevents intermittent power loss, which can cause the vehicle's electrical system to malfunction. Tight connections also reduce the risk of arcing or sparking, which can lead to safety hazards or battery damage.

Corrosion can interfere with electrical conductivity, causing poor performance and potential failures. Therefore, it is essential to regularly inspect battery connections for any signs of corrosion and clean them as necessary. This not only prolongs the life of the battery but also ensures that all electrical components function correctly, contributing to the overall safety and reliability of the vehicle.

Loose connections, signs of excessive corrosion, or frequent disconnections are not optimal practices, as they compromise the functionality and safety of the vehicle’s electrical system.
