The 8steps are: Boost, de-sulphatation, bulk, absorption, after charge, test, maintenance and time.
1st step: “Boost charging” wakes up the battery so it can absorb the charging energy. Makes sure
the battery is charged with maximum capacity. This first step is time limited to maximum 30 minutes.
2nd step: De-sulphatation. 3rd step: Bulk charging, where the battery is charged with maximum
current from the charger until the battery reach 14.0V (cold 14.4V). 4th step: Absorption, where the
charging current drops while the battery’s being charged. This third step is time limited to 6 hours to
prevent the battery to be overcharged. 5th step: After charge with constant current until voltage
reaches 14.4V (cold 14.8V). 6th step: Tests the battery voltage stability. 7th step: Maintenance, the
charging current is now at minimum to maintain the charging voltage to be constant. This voltage
can be adjusted 13.2V for SLA/GEL and 13.5V for AGM/WET. 8th step: Time, the charger can be
continuously connected to the battery and automatically start charging when needed.
