Another point is that I have seen completely dead batteries test at 12.5 volts- batteries that would power a very high impedance input to a meter, but not a #57 clearance bulb. I have not ever worked on a frozen battery, but I would much rather the charger default to the non-explosive mode is there is any doubt.
That's just me though.
