MotoBatt 12V, 1.25A Big Boy Charger & Maintainer with 9 Stage Charging and Maintenance process.
9 Stage Charging and Maintenance Process:
Qualification Phase: ensures battery is in good condition (will not begin if battery is below 2.0 volts)
Battery Rescue Phase: used if voltage has risen unusually high due to plate sulfation
Soft Start Phase: used if charger detects very low initial stage of charge
Pulse Mode Phase: high frequency pulse charge, helps newly recovered battery to accept charge as it enters next phase
Recondition Phase: works the battery at a slightly higher voltage/amperage to "re-activate" the battery plates for improved depth of charge & charge acceptance
