Provided there are no other 12-volt systems operating and if the battery is discharged enough, the maximum rate the converter will recharge the batteries is the maximum amount of amps created by the converter. The last two digits of the part number indicate its maximum current capability in amps.

A: Parallax converters feature over current protection, short circuit protection, reverse polarity protection, and thermal shutdown protection.
In a short circuit, over current, or thermal issue the converter will shut down nearly instantaneously to protect itself. The converter will reset itself once the issue is resolved. Additionally, protection is also included to help protect your property and safety in the event of catastrophic failure which can be caused by liquid intrusion, etc.
A: The issue we have with "smart charger technology" (when used in an RV) lies more with the application of the technology than the technology itself. In a typical RV 12 volt electrical system, the converter/charger and the battery or battery bank is connected in parallel with the rest of the 12 volt distribution system. In "parallel" means where the charging source (converter/charger) positive and negative output is electrically connected to both the battery bank positive and negative, and the 12-volt distribution system positive and negative, at the same time. The voltage output of the converter "smart charger" is based on a "detected" battery voltage. The converter "smart charger" claims to "monitor" and respond to battery condition while connected to the entire 12 volt system. Unless the charging source (converter) has a separate or isolated charging output, we do not agree that a converter or charger can effectively differentiate requirements of the batteries from other 12 volt loads while simultaneously connected to the rest of the 12 volt distribution system in the RV.
Detected use or voltage change on the RV 12-volt load system (i.e. lights, pumps, etc. being turnedon) generally keeps these devices at a 13.6 -13.8 "float" voltage. This raises the question whether any real additional benefit is being provided to the battery bank unless the coach remains in a "non-use" storage condition. If a converter "smart charger" is only connected to the battery bank and can therefore monitor only battery voltage or current, and is not also connected "in parallel" with the 12 volt distribution system, we have no problem with the application of "smart charger technology".
A: There are many people using Gel Cell and AGM batteries with our converters/chargers. We do recommend that the battery manufacturer’s specifications be checked to ensure that the batteries chosen have "float voltage" requirements consistent with the converter output float voltage which is 13.2 - 14.1 VDC. Using a Parallax converter with patented TempAssure capability will enhance the charging function to more effectively charge a Gel Cell or AGM style battery.
