- The harness allows for quick and convenient connection of the charger when needed.
4.2 Connecting to AC Power
Once the charger is securely connected to the battery, plug the AC power cord into a standard wall outlet (100-240V, 50-60Hz).
5. Operating Instructions
The OptiMate 5 Start/Stop operates automatically once connected. The charging process follows a 6-step program.
Image 5.1: The OptiMate 5 Start/Stop provides fully automatic charging, requiring no supervision.
5.1 Charging Process
- Initialization: The charger checks the battery's voltage and condition.
- Desulfation/Recovery: If the battery is deeply discharged (as low as 4V), the charger will attempt to recover it.
- Bulk Charge: Charges the battery at maximum current until it reaches approximately 75-80% capacity.
- Absorption Charge: Charges the battery to 100% at a decreasing current.
- Voltage Retention Test: The charger tests the battery's ability to retain charge.
- Maintenance Charge (Float/Pulse): Once fully charged, the charger switches to a long-term maintenance mode, delivering small pulses of current to keep the battery at optimal charge without overcharging. This is a 24/7 mode.
Indicator lights on the charger will show the current stage of the charging process. Refer to the charger's label for specific light indications.
