Typically closer to 9v Sam , but after its made contact it won't release until around 5v

Hi Sam
Ours switch on at 7.1V and off at 4.1V
They are 12V 30A 5 pin
Regards
Derek.

What are you trying to do with it Sam?
The "pull in" and "drop out" voltages vary amongst manufacturers and models.

oh.. i was going to put it from the second battery to the fridge so when the voltage drops too low the relay would cut out and stop draining the battery. like a cheap voltage drain switch thing i suppose..

Nice idea Sam but it won't work I'm afraid.
By the time most 12V relays reached the "drop out" voltage the battery would be
well below its minimum voltage. Take a look at some of the electronic cut-out devices available; they are not too expensive.

Why don't you use a proper cut out.

That one switches off at 11.2V. This is a bit too low IMO to save a battery.
The gadget has an English front panel but the important details on the back are in German!
Abschaltspannung = switch off voltage
Einschaltspannung = switch on voltage
Max. Stromaufname = power rating
