Anyone know how low you can go? Reason I ask is because I have an ARB 12v fridge freezer. I can set it's battery monitoring feature at several levels, but on all but the most relaxed it cuts out because battery voltage is lower than threshold. Start the vehicle and everything is fine, of course. The low setting, however, would allow the batt to drop to 11.1v...I'm testing it overnight tonight, but anyone care to guess if I'll be reaching for the jump leads in the morning? Right now I have the engine off, freezer holding at -6C and get 12 v across terminals while it's running, 12.2 when not (it was only 12.25 before I started).
As an extension to that, to have a resting battery at about 12.25 v seems a tad low to me, even my wife's Versa shows 12.5. Is this just a function of the crappy oem battery or am I wrong about what I should see across the terminals with everything off? She starts vigorously every time (except maybe tomorrow...).
