It appears the PD9130 Converter/charger unit only produces a single 13.6VDC Output with the capacity of 30AMPS unless you have the CHARGE WIZARD (Thanks WESTEND for pointing this out)...
Specifications
Input: 105-130 VAC, 500 Watts
Output: 13.6 VDC, 30 Amps
My experience with just using the 13.6VDC will tend to boil out battery fluids if left ON for a long period of time...
It is perfectly ok to use a single mode charger but one must keep a good eye on the battery fluids. Allowing the boiling out of fluids will damage your battery and require replacement...

I am not familar with the PD9130 unit but if it has a CHARGE WIZARD that allows it to do the multi-smart mode charging modes that would be a great way to maintain your battery.
I read this statement in one of the brochures for the PD9130...
"The Charge Wizard is a microprocessor-controlled system that constantly monitors the battery voltage and use to ensure a rapid; yet, safe, recharge. The Charge Wizard can select one of three charging voltages and one of four operating modes depending on the condition and use of the battery."
What you want is to have 14.4VDC, 13.6VDC, 13.2VDC operating modes.
I have the PD9260C Converter/charger unit that supports theses smart mode voltages. It almost takes care of my multiple batteries but I still do battery checks at least once a week or when using it...
I would also say if you are thinking about increasing your battery bank with additional batteries and you want to be able to go from 50% charge state to the 90% charge state in a quick three hour charging period you will want to have enough capacity to provide each battery in your bank with 17-20AMP DC Current. I replaced my 30AMP single mode charger with the PD9260C 60AMP Smart mode charger to do this for me in 2009.
