Everything a $30 switch won’t do
Kills the silent drain
Modern vehicles never fully shut off. SmartGuard breaks the circuit completely, so the alarm, clock and computers can’t bleed your battery flat while it sits.
Won’t drain itself
A magnetic-latching design holds the disconnect on roughly 3 mA — a fraction of what relay-style switches pull around the clock.
Voltage at a glance
A built-in display shows battery voltage, so you always know where you stand — no meter, no guessing.
Cut power from the remote
Two key-fob remotes disconnect and reconnect without opening the hood or crawling into the bilge.
Built to last
Pure-copper contacts and a sealed housing stand up to heat, cold and weather season after season.
Fits what you own
Works on 12V and 24V systems — RVs, boats, diesel trucks, classic cars and more.
Why not just use a cheap remote switch?
Goes on in minutes
If you can tighten a wing nut, you can install it — no wiring changes, and it’s fully reversible.
Clamp on
Fit it onto the negative battery terminal.
Hand-tighten
Snug it down — no tools or cutting needed.
Press the remote
Cut power and watch the voltage display light up.

Questions owners ask
Won’t this device drain my battery too?
No — that’s the whole point. Unlike relay-style switches that pull power constantly, SmartGuard holds its disconnect on roughly 3 mA, so it protects the battery instead of draining it.
Will it fit my vehicle?
It clamps onto a standard negative battery terminal and works on 12V and 24V systems — RVs, boats, trucks, classic cars and most powersports.
Is it hard to install?
No. Clamp it on, hand-tighten, press the remote. No wiring changes, and it’s fully reversible.
What if I lose the remote?
There’s a manual button on the unit, and it ships with two remotes so you have a spare.
