7 Stages of Charge

1. Desulphation: Breaks down lead-sulphate.
2. Soft Charge: Gently introduces power.
3. Bulk Charge: Delivers maximum current.
4. Absorption: Reduces current to absorb more power.
5. Analysis: Tests if the battery is fully charged.
6. Recondition: Helps bring the battery to full charge if needed.
7. Float: Maintains optimum charge without overcharging.
