Soft Start

Soft Start - “Soft Start” slowly charges the battery with 14.25V (10% of rated current). As soon as the max Soft Start timer (starts immediately when entering “Soft Start”) of 6 hours is reached or when the battery reaches 10V for 30 seconds the charger switches to the “Bulk stage”


Bulk - “Bulk” charges the battery with 14.3V (100% of rated current) until the battery reaches 13.25V. As soon as the battery reaches 13.25V the Bulk timer will start counting after which it can charge the battery up to 12 hours until the voltage reaches 14.25V. As soon as the max Bulk timer (starts when voltage level is above 13.25V while in “Bulk”) of 12 hours is reached or when the battery reaches 14.25V for 30 seconds the charger switches to the “Absorption stage”


Absorption - “Absorption” charges the battery with 14.25V. As soon as the Absorption timer (starts immediately when entering “Absorption”) reaches 14 hours or when the charge current drops below 10% of the rated current for 30 seconds the charger switches to the “Float stage” 


Float - “Float” keeps the charger on a specific voltage level of 13.25V (100% of rated current) for a period and then will switch to the “Maintenance stage”


Maintenance - As soon as the re-cycle timer reaches 14 days (336 hours) or when the voltage drops below 12.8V for 30 seconds the charger switches back to “Bulk stage”
