Charging Steps.
Step 1 & 2: Analyze & Diagnose
Checks the battery’s initial condition, including voltage,
state-of-charge and health, to determine if the battery is
stable before charging.
Step 3: Recovery
Initializes the Recovery desulfation process (if needed) for
deeply discharged or sulfated batteries by pulsing small
amounts of current.
Step 4: Initialize
Starts the charging process with a gentle (soft) charge.
Step 5: Bulk
Begins the Bulk charging process based on the condition
of the battery and returns 80% of the battery’s capacity.
Step 6: Absorption
Brings the charge level to 90% by delivering small amounts
of current to provide a safe, efcient charge. This limits
battery gassing and is essential to prolonging battery life.
Step 7: Optimization
Finalizes the charging process and brings the battery to
maximum capacity. In this step, the charger utilizes
multi-layered charging proles to fully recapture capacity
and optimize the specic gravity of the battery for
increased run time and performance. The charger will
switch to Maintenance if the battery tells the charger that
more current is needed.
