CHARGING INSTRUCTIONS

AA and AAA Size (Automatic Quick Charge)

1.This charger will charge 2 or 4 batteries at one time. Slide the switch above the battery compartment to the “2” or “4” position according to the number of batteries you wish to charge. When charging 2 batteries only, use the left side of the battery compartment, leaving the 2 spaces on the right side empty. When charging 4 batteries, slide the switch to the “4” position and insert all 4 batteries to be charged (see figure 1).

2.The battery compartment is adjustable to fit either AA or AAA size batteries. If you are charging AAA size batteries, make sure the handle at the top of the battery compartment has been moved all the way down until it has clicked into place. If you are charging AA size, make sure the handle is lifted all the way up into the notch located at the top of the battery compartment. After adjusting the compartment to fit the size batteries you wish to charge, insert either 2 or 4 AA or AAA batteries into the charger. Do not mix AA and AAA batteries when charging.

3.Select the AC adapter or DC/Auto Cord adapter, depending on whether you are using the charger at home or in the car. Be aware that when using the DC/Auto cord, many cars do not supply power to the cigarette lighter while the key is in the off position. Plug the selected power adapter into the power source available, and plug the connector, at the end of the adapter cord, into the power input jack on the top of the charger unit. The red “Charge” indicator LED will glow Red to show charging is taking place.

4.After the proper charge time, the red “Charge” LED will go off and the Green “Ready” LED will come on to indicate that the charge is complete and batteries are ready for use. Once the green “Ready” LED is on, the charger switches to “trickle” mode to keep the batteries at full.

5.Once charge is complete, remove batteries and unplug charger as soon as it is practical. Do not leave batteries in charger for extended periods of time (more than 1-2 days) OR when the charger is not plugged in. Unplug the charger when not in use.

6.Begin again at Step-1to charge the next set of batteries.

Bad Cell Detection:

When charge process is started, the charger detects the health status of each of the cells in the battery compartment. If any battery is unsuitable for charging, i.e. short circuit or reversed polarity, the red “Charge “ LED will flash. The damaged cell(s) should be properly disposed of.
