Tips for Buying and Using a Battery Disconnect Switch
1. Check the amperage rating before buying to know if the switch is suitable for the battery of your vehicle, boat, or RV. Different modes of transportation have different alternators that output varying power levels.
2. Always remember to turn off your vehicle before disconnecting the battery. This will prolong the lifespan of the battery, the electrical components, and the disconnect switch.
3. Avoid random power cuts or you risk damaging the locking navigation system and other anti-theft features.
4. When replacing the battery, disconnect the switch—starting with the negative terminal.
5. If you are not sure about installation, consult a professional to avoid system failure.
