• 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 5-Stage Charging Curve
The NFC2200 is controlled by a 12-bit AD microprocessor with 5-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:
• Soft Start: 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 10V.
• Bulk: Major charging stage where the battery receives the majority of its charge. During
this stage the battery brought to 60 - 80% of its charger. The NFC2200 charger delivers
maximum current until the terminal voltage has risen to the set level of 14,2V for
Standard battery selection and 14,0V for Gel Cell battery selection and 14,4V for Deep
Cycle selection.
• Absorption: Completes the charge up to virtually 100% at a constant voltage. The
current tapers off after the current reached the minimum level.
• Float: This is a maintenance charge at constant voltage, keeping the batteries at 100%
charge. Normal charging mode is time-limited (max 10 days) while supply mode goes on
indefinite without damaging the battery.
• Pulse: This is a maintenance charge for maximum battery life. Charging varies between
80% and 100% state of charge. The battery receives a pulse, starting a new charge cycle,
when voltage drops to set limit. This keeps the battery in perfect condition when it is not in
use. The charger can be connected for months keeping the batteries fresh.
LED display
The unit is built-in with LED display for showing charger status:
• REVERSE – RED LED – DC clamps are connected in reverse polarity.
• FAULT - RED LED – Battery Fault.
• CHARGING – AMBER LED – The charger is charging to the battery.
• FULL - GREEN LED – The battery is fully charged and the charger is in maintenance mode.
• 3 x 7 Segment LED display – Indicating Charging current, battery voltage and
charging %
