INSTRUCTION MANUAL: CHARGE PRO

DC Connection Precautions

1) Connect and disconnect dc output clips only after removing ac cord from electric
outlet. Never allow the ring terminals to touch each other.
2) Check polarity of the battery posts. The POSITIVE (POS., P, +) battery post usually
has a larger diameter than the NEGATIVE (NEG., N, -) post.
3) Connect Red charger output wire to POSITIVE post, Black charger wire to NEGATIVE.
See below diagrams for more details.
4) Do not face the battery when making the final connection.
5) When disconnecting charger, disconnect AC cord and then remove clips from
battery terminal.

OPERATING THE CHARGER

Charge Cycle
1) Soft Start – Charger verifies connections are good and the battery is capable of
accepting a charge. Batteries with very low voltage will be slowly charged to not
harm the battery. When the battery voltage reaches 10V for 30 seconds the charger
switches to the next stage.
2) Bulk Stage – the charger uses constant current and charges the battery to 14.3
volts. When the battery holds the voltage of 14.3 volts for 30 seconds the charger
switches to the next stage.
3) Absorption Stage - the charger uses constant voltage to charge the battery until the
charge current drops. At this point the charger will switch to the next stage.
4) Float Stage – the charger finishes the charge cycle by keeping the battery at 13.3
volts for a period of time and then moves to the next stage.
5) Maintenance – the charger will monitor the battery and if the battery voltage drops
below 12.8 volts or if 14 days have passed since the last charge, the charge cycle
will start automatically.
