Figure 7 MX60 MULTI-STAGE BATTERY CHARGING
The MX60 charge controller is a sophisticated, multi-stage battery charger that uses several regula-
tion stages to allow fast recharging of the battery system while ensuring a long battery life. This
process can be used with both sealed and non-sealed batteries. The MX60 has a preset recharg-
ing voltage set points (Absorb & Float) for the selected nominal battery voltage, however, always
follow the battery manufacturer's recommended charging regulation voltages. The MX60 charging
regulation stages correspond to the chart in Figure 7.
