The Charge Wizard PD9105 (for Lead-Acid Batteries) is designed to plug into the standard TCMS port located on the front of all models of the Intelli-Power 9100 Series Converters. The Charge Wizard is a microprocessor-controlled unit that constantly monitors the RV battery voltage and then selects one of three charging voltages and one of four operating modes to properly re-charge or maintain the RV battery. The addition of the Charge Wizard makes your 9100 Series converter an intelligent battery charger that will safely and rapidly recharges a discharged battery by selecting the Boost Mode (14.4V) of operation. Once the battery reaches 90% of full charge, the Charge Wizard automatically selects the Normal Mode (13.6V) to safely complete the charge. The Storage Mode (13.2V) is automatically selected after 30 hours of non-use of the 12-volt RV electrical systems. The lower charging voltage in the Storage Mode of operation reduces battery gassing and water usage, while maintaining the charge. Every 21 hours when the system is operating in the Storage Mode, the Charge Wizard will automatically switch to the Equalizing Mode of operation. The Equalizing Mode increases the charging voltage up to 14.4 volts for 15 minutes. This increased voltage mixes up the battery electrolyte and prevents battery stratification and the resulting problems of battery sulfation.
The Charge Wizard functions are fully automatic, however you can test the Charge Wizard’s functions manually by pressing and holding the MODE SELECT SWITCH BUTTON DOWN. When the button is first pressed, the light will be ON all the time, indicating it is in the BOOST Mode (converter output 14.4 VDC). If you continue to hold the button, the unit will switch to the NORMAL Mode (converter output 13.6 VDC) and the light will blink approximately once a second. If you continue to hold the button down the unit will go into the STORAGE Mode (converter output 13.2 VDC) and the light will blink approximately every five- (5) seconds. NOTE: No matter which mode you manually select, the Charge Wizard will automatically return to the NORMAL Mode of operation after 4 -hours.
