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 multi-stage charge cycle, dependent upon battery geometry, with software programmable set points. 1. Constant Current Mode: Output current is 4.0A max for the 4A models or 8.0A max for the 8A models.

4.1.4 When charging is complete both the yellow and green lights will remain 4.2. Programming the Charger The Model 1604 or 1608 charger has a number of parameters that can be programmed by the user, using a Curtis 1311 handheld programmer. These programming variables allow the charger's performance characteristics to fit the needs of the individual application.
