Charging Mode1) Precharge stage (T1): When the battery voltage is lower than normal standard, the charger can not withstand large current charging. The charger will supply small current for charging, which has the functions of activation, repair and battery life extension. When the output voltage reach normal value or at the T1 of the timing period, the charger will switch to fast charge stage automatically.
2) Fast charge stage (T2, T3): When battery is on the main period of charging, charger will quickly charge the batteries with a constant flow, at the maximum current which can be used to the battery. When the battery voltage raise up to the set value, the charging current will fall off gradually, when the values drops to the set value or at the T3 of the timing period, the charger will lower the charging voltage and enter to the float charge stage (if the time reaches to T2 time period, when the charging current haven't dropped to the set value of T2, charger will be off, and enter to battery failure protection status).
3) Float charge stage (T4): The charger will switch to float charge stage, which ensure the battery is fully charged and reduce gas evolution and water loss, avoid battery polarization, vulcanization and thermorunaway, extend the battery service life. When the output current drops to the set value or at the T4 of the timing period, the charger will switch to pulse maintenance phase automatically.
4) Pulse maintenance stage (T5, T6): In the pulse maintenance stage, the charger can compensate for the loss of the battery self-discharge, and recover the battery capacity by removing the hard crystallographic lead sulfate in the battery.
Note:A. Flooded lead-acid battery is slightly different on charging mode, please refer to charging curve to check the details.
B. Charging mode can be customized.
