Absorption (Lamp 3)
Complete charge up to virtually 100%. The terminal voltage is maintained at the set level. During this phase the current
tapers successively. Once the current has tapered to the set limit, this phase switches to being timed. If the total time for
Absorption exceeds the time limit the charger automatically switches to maintenance.
Analysis (Lamp 3)
Testing self-discharge. If self-discharge is too high, charging is discontinued and fault mode is indicated.
Maintenance charging - Float (Lamp 4)
Charging at constant voltage.
Maintenance charging - Pulse (Lamp 4)
State of charge varies between 95% and 100%. The battery receives a pulse when the voltage drops and keeps the
battery in perfect condition when it is not in use. The charger can be connected for months at a time. The charger
continuously measures the terminal voltage to determine whether a charging pulse should be initiated. If the battery is
loaded and/or the battery’s terminal voltage drops the charger starts a charging pulse until the terminal voltage reaches
the set level. The charging pulse is then discontinued and the cycle is repeated infinitely. If the terminal voltage drops
below a lower limit, the charger automatically goes back to the beginning of the charging curve.
Recond (Lamp 5)
This mode is used to recover deeply discharged flooded batteries. Recondition of deep discharged batteries. The voltage
increases with reduced current for a limited time period. The higher voltage starts some gassing and mixing of the acid,
which is beneficial for both battery capacity and expected life. Note that the battery could emit explosive gas during
Recond. Recond is performed between Analysis and Maintenance.
