Quest Q2 Smart Charger with 4 AA NiMH Batteries

The kit pairs a compact smart charger with four 2700 mAh AA NiMH cells. It is suited for households that regularly power remotes, toys, wireless keyboards or game controllers and want a single device to keep cells ready. The charger handles one to four batteries at once in independent slots. Each cell delivers 1.2 V and is rated for up to 1000 recharge cycles.

Charging limits and safety features

The charger accepts 120 V AC at 60 Hz and draws 9.7 W, supplying 12 V at 500 mA to the slots. AA cells between 2000 and 2900 mAh take four to five hours to reach full charge, while AAA cells from 700 to 1200 mAh need two to three hours. Negative delta V cut-off detection and a safety timer stop the charge automatically, then switch to a trickle current to maintain capacity. Short-circuit, reverse-polarity and overcharge protections are built in.

Build quality and daily use

The unit is UL listed and described as very compact, fitting easily on a desk or shelf. Individual LEDs show red while charging and green when a cell is full, and the charger emits an audible tone when a battery is inserted and again when charging completes. Independent slots let you mix AA and AAA sizes or charge an odd number of cells without waiting for a full set. No memory effect means cells can be topped up at any state of discharge.

Questions about this item

Should I choose these 2700 mAh AA cells or a lower-capacity pack?

The 2700 mAh rating gives longer run-time per charge in high-drain devices; lower-capacity cells will need recharging sooner but cost less upfront.

What does 2700 mAh actually deliver in a camera or flash unit?

Expect several hours of continuous use in a typical digital camera or flash before the voltage drops below the usable threshold.

The charger uses a 12 V 500 mA output — how does that affect charge speed?

That output limits each of the four independent slots to roughly 500 mA, so the included 2700 mAh AA cells take about 4 to 5 hours to reach full charge.
