MotoBatt 12v, 750mA Little 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
• Bulk Charge Phase: constant current, takes battery to 80% charge capacity
• Absorption Phase: constant voltage, reduced current takes battery to 100%
• Check Phase: checks battery to make sure it holds charge properly
• Maintenance Phase: battery can be left safely on charger indefinitely, unit maintains battery at full state of readiness
