Charging characteristic:
- Battery Test (stage 1): After connecting to the power supply, press MODE button to select appropriate battery charging stage. After connecting to the battery, the charger will automatically detect battery performance. In normal status, the battery will enter Stage 2 in 5 seconds. 6 V batteries lower than 3,5 V or 12 V batteries lower than 5 V are invalid and beyond handling.
- Desulphation (stage 2): Detect vulcanized battery. Remove sulphate on the battery electrode with pulse current and voltage to restore battery capacity.
- Soft Start (stage 3): Initial battery test to determine battery condition. If the battery is severely discharged charger will begin the Soft Start stage. Charging starts with reduced current until battery voltage reaches a normal condition for charge.
- Bulk (stage 4): Major charging stage where the battery receives the majority of its charge. During this stage the battery brought to 75-80 % of its charger. CRX321 charger delivers maximum current until the terminal voltage has risen to the full charge level for normal battery.
- Absorption (stage 5): Completes the charging up to virtually 100 % at a constant voltage. The current tapers off after the current has reached the minimum level.
- Analysis (stage 6): Test whether the battery is able to keep battery power or not. A battery not able to keep battery power will be deemed as an invalid battery, and the charger will give out warning and the red mistake indicator will illuminate.
- Float (stage 7): Maintenance charging at constant voltage, keeping the batteries at 100% charge. Normal charging mode is time-limited (max 10 days) while Float mode goes on indefinite without damaging the battery.
- Pulse (stage 8): Conduct a compensating charging for the battery to reach its capacity to 95%-100%. The charger detects the battery voltage, and give out charging pulse when necessary in order to ensure a full charging.
