Use this connector to attach the power supply to the charger. The universal power supply accepts input
voltages between 90–265 volts.
Battery Charging
Charging Process
This charger charges Dolphin 6500 Li-Ion 3300mAh packs in an average of 5 1/2 hours for a fully depleted
battery. It takes less time if the battery has some charge. Each charging slot works independently of the
other three. As battery packs charge, the charging circuitry follows the two-step charging process (CC-
CV) that is recommended for Li-Ion batteries. The process monitors changes in temperature, current, and
voltage.
Temperature
The six-hour charge time applies when batteries are charged within the recommended temperature range
of 50° to 95° F (10° to 35°C). Temperature has a significant effect on charging. For best results, battery
packs should be at room temperature before inserting in the charger.
When the battery temperature exceeds 40°C, the charger may exceed the stated six-hour charge
time. The charger stops charging if the battery temperature is greater than 40°C, but will begin
charging again when the battery temperature is less than 40°C.
Charging Batteries
1. Supply the charger with power.
2. Insert batteries into the appropriate slots.
The Status LED for each slot turns red to indicate that the battery is properly seated and has begun
a charge cycle.
