I have carried out many low voltage start tests and you can easily start your motor with a cranking battery voltage as low as 11.5v.

So the 12.0v cut-out voltage level of the SC80 will leave with a healthy cranking battery capacity to be able to start any vehicle, even on the coldest of mornings. I sell my kit into countries up in the Arctic Circle and no one has problems starting their vehicles with the 12.0v cut-out level.

How old is your cranking battery?

Tim,
You are probably right about my bout of paranoia again. Just not used to it as I have been able to leave my wife's car for long periods without a problem. But her car does not have the warning message feature.

The batteries are just over two years old - new with the car. The Optima aux battery closer to 2 years than the main.

I have a bit better understanding, maybe , of how your gear hangs together, so reckon there is a fair amount of protection there.

I think I will just go and worry about something else now . (to much time on my hands I think).

Many thanks

Richard

I wouldn't assume the cranking battery is ok just cos it's only a bit over two years since you bought the car...
