Three-stage Charging
Multistage charging ensures batteries receive optimum charging, but with minimal wear and tear, regulating the voltage and current
delivered to the batteries in three automatic stages:
Bulk: Replaces 70-80% of the battery’s state of charge at the fastest possible rate.
Absorption: Replenishes the remaining 20-30% of charge, bringing the battery to a full charge at a slow, safe rate.
Float: Voltage is reduced and held constant in order to prevent damage and keep batteries at a full charge.
