Charging a Very Cold Battery
If the battery to be charged is very cold (in temperatures below freezing — 0°C/
32°F), it cannot accept a high rate of charge. The initial charge rate will be low. The
charge rate will increase as the battery warms. Never attempt to charge a frozen
battery.

TROUBLESHOOTING
Display Indications/Common Problems/Possible Solutions
No Functions
• Check and make sure the charger is plugged into a live 110/120 volt AC outlet.
• Follow the steps outlined in the Operating Instructions section.
F01 — Internal Shorted Cell Battery
If the battery being charged has an internal shorted cell, the F01 will show. We
recommend taking your battery to a certified automotive service center for
evaluation.
F02 — Bad Battery Connection or Battery Voltage Too Low to Accept
Charge
When F02 appears, the most common cause is poor connection to battery.
• Follow the steps outlined in “Important Safety Instructions” at the front of this
manual to disconnect AC cord and clamps, clean battery terminal and
reconnect.
• If the situation persists, we recommend taking your battery to a certified
automotive service center for evaluation.
F03 — Sulfate or Unchargeable Battery
Appears when the battery is highly sulfated and cannot accept normal charge
current.
• Follow the steps in “Recondition Mode” to recondition the battery.
• Follow the steps in “Equalizing” to equalize the battery.
• If the situation persists after reconditioning and equalizing, we recommend
taking your battery to a certified automotive service center for evaluation.
F04 — Overtime Condition
Appears when charging time exceeds 18 hours. You may be using a charge
current rate too low for a large battery. Select higher charge rate to charge the
battery.
F05 — Overheated Condition
The ventilation grill that prevents the air from flowing in and out of the charger
may be blocked.
• Follow the steps outlined in “Important Safety Instructions” at the front of this
manual to disconnect AC cord and clamps, allow the unit to cool for 30 minutes and
reconnect.
• Make sure there is ample ventilation before resuming operation.
F06 — Reverse Polarity
The connections to the battery’s POSITIVE and NEGATIVE terminals are
incorrect. Follow the steps outlined in “Important Safety Instructions” at the front of
this manual to disconnect AC cord and clamps and reconnect to battery with
correct polarity.
