USING YOUR BATTERY CHARGER
OVERVIEW
Using the battery charger is very simple. First, connect the battery and AC power following the precautions listed under “OPERATING INSTRUCTIONS”. Then select the appropriate BATTERY TYPE and CHARGE RATE for your battery. The charger will then do everything automatically. This section explains a few details.
CHARGING: If the charger does not detect a properly connected battery, the CHECK (red) LED will light continuously until a battery is detected. Charging will not begin while the CHECK light is on. When charging begins, the CHARGING LED will be lit.
AUTOMATIC SHUT OFF: When the 2A, 12A, or 25A charge rate is selected, the charger is set to perform an automatic charge. When an automatic charge is performed, the charger stops charging automatically after the battery is fully charged.
ABORTED CHARGE: If charging can’t be completed normally, charging will be aborted. When charging is aborted, the charger’s output is shut off and the red CHECK LED and digital LED blink on and off (at opposite times). In that state, the charger ignores all buttons. To reset from after an aborted charge, either disconnect the battery or unplug the charger.
DESULFATION MODE: If a battery is left discharged for an extended period, it could become sulfated and not accept a normal charge. If the charger detects a sulfated battery, the charger will switch to a special mode of operation designed for such batteries. Activation of the special desulfation mode is indicated by
blinking the CHARGING LED. If successful, normal charging will resume after the battery is desulfated. The CHARGING LED will then stop blinking and light continuously. Desulfation could take up to 10 hours. If desulfation fails, charging will be aborted and the CHECK (red) LED will blink.
COMPLETION OF CHARGING: Charge completion is indicated by the CHARGED (green) LED; when lit, the charger has stopped charging and switched to the Maintain Mode of operation.
MAINTAIN MODE: When the CHARGED (green) LED is lit, the charger has started Maintain Mode. This mode of operation is also known as
GENERAL CHARGING NOTES: The charger is designed to control its cooling fan for efficient operation. Consequently, it is normal for the fan to start and stop when maintaining a fully charged battery. The fan does not normally run in Tester Mode.
If the charge mode is changed after charging has started (by pressing the CHARGE RATE or BATTERY TYPE button), the charging process will be restarted.
The voltage displayed during charging is the charging voltage and usually will be higher than the battery’s resting voltage.
