The D34 will charge quicker than the OEM. It's full charge voltage will be different as well. Don't forget your vehicle still draws power when turned off. As you have two batteries power will come from both until the isolator drops down to 12.7v or so volts then the vehicle will continue to draw power from the main battery. So it is normal to have different voltages.Winston.
