This battery disconnect switch is fully compatible with both 12V and 24V electrical systems, making it suitable for passenger cars, trucks, RVs, boats, and other vehicles that use either voltage standard.\u003c\/p\u003e\n\u003ch4\u003eQ: Why cut the negative terminal instead of the positive?\u003c\/h4\u003e\n\u003cp\u003eA: Disconnecting the negative (ground) terminal is the safer approach because it minimises the risk of accidental short circuits. It also complies with best-practice automotive wiring guidelines for battery isolation switches.\u003c\/p\u003e\n\u003ch4\u003eQ: Will this switch prevent battery drain when the car is stored long-term?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely.
