For those who store their car over the winter with a battery tender on the car this may be an important consideration. You could remove the battery from the car's circuits by opening the switch before you connect a charger, but the battery remains in the car. So it is very easy. Also having the battery disconnect switch I believe would help limit voltage spikes when installing a new battery by using the switch to first open the negative cable before removing the old battery and then closing the switch only after the new battery and cable are installed. Thus no sparking when connecting the cable. What you think?
the guys that fly r/c planes powered by electric motors have found a way to avoid sparks when connecting the battery by soldering a thin wire to each terminal and a resistor between. there is a connector that allows current to flow or stop. when connecting, you do the wire before, then the main. this way there is no spark. perhaps some1 with the knowledge could calculate the size of the resistor. just an idea-that works.
