I think you will find that the coils are not continuously rated and will burn out also a battery contactor coil is normally connected internally to + so - side is connected to ground via master switch. A starter solenoid coil - is connected internally to ground in most cases

Could one use a starter contactor as a battery contactor? I understand they are subjected to different duties but also understand the on/off action is when they are most abused. Would I be wasting too much power just by keeping the contactor on (power to the coils)?

I think most starter contactors are rated 'intermittent duty'. assuming that's correct, you'd risk not just wasting current, but overheating the coil in the contactor.Â
