Eneloop BQ-CC17 Advance Charger for AA & AAA Rechargeable Batteries

Individual Charge Control

BQ-CC17 features Individual Charge Control, which means you can charge any mix of one, two, three, or four eneloop or eneloop pro batteries in AA or AAA sizes simultaneously, even those with different capacities. Each slot has its own LED that shines green while charging. Once the battery is full, the light below its slot turns off.

Battery checker with LED indicators

The charger checks if the installed batteries can be charged. If a battery is inserted incorrectly or a dry battery is installed, the light below its slot flashes green, and the power supply to the affected slot is shut off for safety.

Supported battery combinations

Individual Charge Control allows you to recharge any combination of up to four AA/AAA eneloop and eneloop pro, even single batteries or a mix with different sizes and capacities. Minus Delta V Control detects when a battery is full and shuts down individual slots just after battery overflow to prevent overcharging.

Using your battery charger

Step 1

Insert the batteries into the slots according to the indicated polarity (+/-). When inserting a battery, you should fit the battery's negative terminal end first and then gently press the top of the battery into the slot. Pull out the positive terminal end first when removing the battery.

Step 2

Connect the charger to an AC outlet. The LED indicators may blink for a short time while the batteries are checked.

Step 3

After checking is complete, the light below the slot turns solid green to indicate that the installed battery is being charged. If an invalid battery is inserted or a battery is installed incorrectly, the light below its slot flashes green, and power to that slot is shut down to prevent damage to the battery and charger.

Step 4

When a battery is fully charged, the light turns off. Minus Delta V Control detects when a battery is full and shuts down power to that slot just after battery overflow to prevent overcharging.

Step 5

Unplug the charger from AC outlet and remove the batteries from the charger as soon as possible after charging.
