FEATURES
5 STAGE AUTOMATIC CHARGING
This is a fully automatic battery charger with 5 charge stages.
Automatic charging protects your battery from being overcharged so you can leave the
charger connected to the battery indefinitely.
5 stage charging is a very comprehensive and accurate charging technique that gives
your battery longer life and better performance compared to using traditional chargers.
The 5 charge stages are:
Soft Start 1, Soft Start 2, Bulk, Absorption and Float.

Soft Start 1
This is a preliminary charge that is for heavily discharged batteries where the voltage is
between 2-8 Volts. Charge is limited to 5% of set current.
Soft Start 2
This is a preliminary charge that is for discharged batteries where the voltage is between
8-10 Volts. Charge is limited to 25% of set current.
Bulk (Constant Current)
The Bulk stage reduces charging time by charging the battery at the maximum rate
(constant current) to a set voltage, at which point the battery is approximately
80% charged.
Absorption (Constant Voltage)
The absorption stage charges the battery to 100% by adjusting the charge rate allowing
the battery to absorb more power.
Float
The Float stage maintains the battery at 100% charge without overcharging or
damaging the battery. This means the charger can be left connected to the battery
indefinitely.
