I never let my batteries get close to depletedYour alternator is rated to 150A. This switch is rated to 100A. If your battery is severely depleted, you could exceed the current rating of this switch as the alternator charges the battery.
There are plenty of options out there, but start with a unit that exceeds the capability of your system to charge or discharge the battery.
And it says max current 500 for 5 seconds.
