It is designed as a 12v power supply and not a battery charger. It will 'handle' any 12v battery or battery bank including several 12v in parallel or 6v in series.
But the converter is not a battery charger and not a battery maintainer.
The old converters provided a limited bulk mode charging. Their voltage is set so that they aren't too high for temporary float service. That is to avoid boiling off the battery acid too fast. The voltage limitation means that it takes a long long time to get a battery fully charged.
And they don't do a thing to maintain batteries when in storage.
Getting a good battery charger and maintainer, such as the IntelliPower with Charge Wizard or equivalent, is the first thing that should be done before any battery bank upgrading. That will provide a faster return on investment by better battery life and improved capability than anything else.
If using AGM batteries, you will have to get the special ChargeWizard designed for that battery.
