Frequently Asked Questions

Q: Is this car battery cut off switch compatible with both 12V and 24V systems?

A: Yes! This battery disconnect switch is fully compatible with both 12V and 24V battery systems, making it suitable for a wide range of vehicles including cars, trucks, RVs, boats, and more.

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

A: Cutting the negative (ground) terminal is the safer approach. It minimises the risk of accidental short circuits because the positive cable remains insulated from completing a circuit, reducing the chance of sparks or electrical damage.

Q: Does this switch require any tools to operate?

A: No tools are needed. The manual knob design allows you to quickly connect or disconnect your battery by hand, making it fast and convenient for regular use or emergency situations.

Q: Can I use this switch to prevent battery drain during vehicle storage?

A: Absolutely. This switch is ideal for long-term storage. It completely cuts off parasitic power consumption from standby electronics (such as clocks and alarm systems), helping preserve battery life and charge over extended periods.
