Smart charger with four AAA NiMH cells

The DUSLAN A05AA21AA package combines a Quest Q2 smart charger and four AAA Nickel Metal Hydride batteries rated at 900 mAh. It suits households that run remote controls, wireless keyboards or toys and want to stop buying disposable alkaline cells.

Independent slots and microprocessor control

The charger accepts one to four AA or AAA NiMH and NiCd batteries in four independent slots, so mixed sizes and capacities charge simultaneously. Individual LEDs show red while charging and green when full, while negative delta-V detection and a safety timer prevent overcharge. Short-circuit and reverse-polarity protection plus automatic trickle charge keep cells topped up safely.

900 mAh capacity and up to 1000 cycles

Each included AAA cell delivers 1.2 V and 900 mAh, recharging in roughly two to three hours from empty. Rated for up to 1000 cycles, the set replaces hundreds of single-use batteries, but it cannot power devices that demand higher-drain AA cells or voltages above 1.2 V.
