Charging Algorithm & Chemistry

The GENIUS5 uses an intelligent profile that charges, then optimizes, and finally maintains the battery. Specific peak voltage setpoints for each battery chemistry, all at up to 5A—ideal for batteries up to 120Ah while maintaining all battery sizes. It supports lead-acid types (Flooded, Gel, AGM) plus 12V lithium iron phosphate (LiFePO4) batteries with a BMS. After reaching full charge, the charger switches to ongoing maintenance; the Charge LED pulses green during optimization and turns solid green at 100% while maintenance cycles continue. Force Mode allows manual starting on batteries below 1V (returns to normal operation after 5 minutes). For detailed mode/LED behavior, see the NOCO Genius 5 manual link below.
