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.
