Sinergex Nitro 3500 - Charging Stage Explanation; Features and Safety; Product Features

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 12V.
Bulk: Major charging stage where the battery receives the
majority of its charge. During this stage the battery brought to
75% - 80% of its charger. The NITRO charger delivers maximum
current until the terminal voltage has risen to the set level of 14.5V
for Normal battery selection and 14.2V for Gel battery selection.
Absorption: Completes the charge up to virtually 100% at a
constant voltage of 14.5V (GEL 14.2) at +25°C. The current
tapers off after the current reached the minimum level.
Float: Maintenance charging at constant voltage, keeping the
batteries at 100% charge. Normal charging mode is time-limited
(max 10 days) while Float mode chargers indefinitely without
damaging the battery.
