2.6 Battery Types
All chargers are intended for use with lead acid or gel cell batteries only, for their respective voltages.
2.7 Charge Cycle Profile
Models 1604 and 1608 use a
1.Constant Current Mode: Output current is 4.0A max for the 4A models or 8.0A max for the 8A models. Current is held constant until the constant voltage is reached. Output current is reduced during the Constant Current Mode if the charger should begin to overheat.
2.Constant Voltage Mode: Output voltage shall be held at an average voltage of approximately 14.3V for 12V chargers or 28.6V for 24V chargers. The charger will hold the voltage to within 100mV of this value, reducing the current gradually until the charging ends. Charging ends when the current falls below 0.5A or the charger remains in Constant Voltage Mode for more than 4 hours. The charger will shut down and remain in standby.
