•
Never pull out the plug by the cord when unplugging the charger. Pulling on the cord may cause damage to
the cord or the plug.
Precautions When Working with Batteries
•
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye,
immediately flood eye with running cold water for at least 20 minutes and get medical attention immediately.
•
Never smoke or allow a spark or flame in vicinity of battery or Engine.
•
Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery of other electrical
part may cause an explosion.
•
Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-
acid battery.
•
A lead-acid battery can produces a short-circuit current high enough to weld a ring or the like to metal,
causing severe burns.
FEATURES
Automatic and Intelligent 8-Stage Charging Curve
The CRX321 is controlled by a 8-bit AD microprocessor with 8-stage charging characteristic for charging batteries
automobiles, motorcycles, snow mobiles, tractors, personal watercraft, boats etc.
A microprocessor senses the condition of the battery and controls the regulator to provide the right current and
voltage to the battery (charging characteristic). This will give the best effect on charging and give the longest life to
battery.
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. 6V batteries lower than 3.5V or
12V batteries lower than 5V 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.
