Charging Process

Analyze & Diagnose Steps

Initial battery condition check for voltage, state-of-charge, and health.

Recovery Step

Initializes desulfation for deeply discharged or sulfated batteries.

Initialize Step

Starts charging with a gentle (soft) charge.

Bulk Charging Step

Begins charging, aims to return 80% of battery capacity.

Absorption Step

Increases charge to 90%, limits gassing, prolongs battery life.

Optimization Step

Finalizes charging to maximum capacity, optimizes performance.

Maintenance Step

Continuously monitors battery, restarts maintenance if voltage drops.

Charging Times Estimation

Estimated time to charge batteries based on size and depth of discharge.
