Smart Charger with Independent Slots

The DUSLAN A05AA21AA package pairs a Quest Q2 smart charger with eight AAA NiMH cells rated at 1200 mAh each. The charger accepts one to four AA or AAA batteries in four independent slots. Individual LEDs show red while charging and green when full. Negative delta-V detection, a safety timer, short-circuit protection and reverse-polarity guards stop the charge automatically and switch to a trickle current. An audible tone sounds on insertion and again when charging finishes.

Replaces Single-Slot or Timer-Only Units

If you currently use a charger that handles only one pair at a time or relies on a fixed timer, the independent slots and microprocessor control remove the guesswork. The jump is worth it when you regularly cycle mixed-capacity cells or need to top up odd numbers of batteries without waiting for a full bank. Households that only charge a single pair once a month will not see a practical difference.

Eight 1200 mAh Cells for High-Drain AAA Devices

The included cells deliver 1.2 V and are rated for up to 1000 recharge cycles with no memory effect. They suit devices such as wireless keyboards, game controllers or LED torches that draw steady current. The charger replenishes AAA capacities from 700 to 1200 mAh in roughly 2 to 3 hours. It will not charge 9 V blocks, C, D or lithium-ion chemistries, and the 120 V AC input limits use to regions with that mains voltage.

Questions about this item

Does the Quest Q2 charger need a standard 120 V AC wall outlet?

Yes, the charger plugs into a 120 V, 60 Hz mains socket and draws 9.7 W; no special circuit or adapter is required.

What is the most common mistake when inserting the AAA cells?

Reversing the polarity; the charger beeps and the LED stays off until the cell is seated with the positive button against the raised contact.

After roughly how many recharge cycles should I expect the 1200 mAh AAA cells to need replacement?

The cells are rated for up to 1000 charge cycles before capacity drops noticeably.
