A: Yes! This car battery disconnect switch is fully compatible with both 12V and 24V battery systems, making it suitable for cars, trucks, RVs, boats, and other vehicles that use either voltage.

Q: Why disconnect the negative terminal instead of the positive?

A: Cutting the negative terminal is the safer method because it reduces the risk of accidental short circuits. If a tool or the switch housing touches the vehicle's body (which is grounded), disconnecting the negative side first prevents sparks and potential damage.

A: This battery disconnect switch is designed for battery post (pile head) diameters of 16mm–17mm. Simply measure your existing battery terminal before purchasing to confirm compatibility.

Q: Does this switch prevent battery drain when the car is stored long-term?

A: Absolutely. By completely cutting off the negative circuit, this switch eliminates all parasitic draw from standby electronics like clocks, alarms, and ECUs — making it ideal for vehicles in long-term or seasonal storage.
