Battery Charger
Conditioning a Battery in the Charger
1. Place the battery into the charger.
2. Press the right button on the charger (marked with a curved arrow). The red light on the left will go
out and the green light on the right will start to blink. This indicates that the battery is being condi-
tioned. The conditioning cycle may last for up to 7 hours, depending on the remaining charge in the
battery.
3. When the conditioning cycle is completed, a charging cycle will automatically start, indicated by the
red light turning on and the flashing green light going out. The battery is discharged to 12V before
charging begins.
4. When the battery has reached full charge, the green light will illuminate indicating a fully charged
battery is ready.
Conditioning a Battery Manually
To condition a DCI battery pack, you simply
need a low-wattage 12V light (such as a small
automotive side light or an interior light bulb)
and electrical wires to connect the battery pack
