2) Soft Start: This step charges the battery until the terminal voltage has reached a pre-set level.

3) Bulk: This is where the battery gets charged to about 80%.

4) Absorption: The final charging stage; the voltage is maintained at a pre-set level.

5) Analysis: The voltage is measured and the charging is suspended.

6) Recondition: A constant current of 1.5 A is fed to the battery, with a maximum voltage of 15.7 volts.

7) Float: The constant amount of voltage is maintained.

8) Pulse/Maintenance Charging: A pulse of electricity is injected into the battery if it dips below 95% voltage. This keeps the battery in ideal condition even when it’s not in use.
