- Soft Start Charging: Gently introduces current to the battery.
- Bulk Charging: Charges the battery at its maximum rate until it reaches approximately 80% capacity.
- Absorption Charging: Charges at a decreasing rate to bring the battery to 100% capacity.
- Trickle Charging: Maintains the battery at full charge with a small current.
- Battery Test: Checks the battery's ability to hold a charge.
- Recondition Charging: Recovers deeply discharged batteries (if applicable).
- Float & Maintenance Charging: Keeps the battery at optimal voltage without overcharging.
- Small Current to Maintain Charging: Ensures the battery remains fully charged over time.
