DUSLAN ULINOV3 standard battery charger with 4 AAA 900 mAh NiMH cells

Smart Charger and AAA Cells

The DUSLAN ULINOV3 is a smart battery charger bundled with four AAA NiMH cells rated at 900 mAh. It suits households that regularly use remote controls, wireless keyboards, toys or other low-drain devices and want to stop buying disposable alkaline cells. The charger accepts both AA and AAA formats and can replenish two or four batteries at once from a wall outlet, a car socket or a computer USB port. It is not for users who need high-drain cells for camera flashes or power tools.

Negative Delta V Cut-Off

The single specification that decides fit is the negative delta V cut-off detection combined with a microprocessor-controlled charge algorithm. This terminates charging automatically when each cell reaches full capacity, preventing overcharge damage to NiMH or NiCd chemistries. Red LEDs flash during charging and glow solid when the cycle finishes, so you see status at a glance. Buyers who require a basic timer-only charger without voltage-sensing termination should look elsewhere.

900 mAh Capacity and Cycle Life

Each included AAA cell delivers 900 mAh at 1.2 V and is rated for up to 1000 recharge cycles with no memory effect. That capacity comfortably powers clocks, remotes and similar low-current gear for weeks between charges, while the 1.5 to 3 hour recharge window for AAA cells keeps downtime short. The pack runs out quickly in high-drain applications such as digital camera flashes or motorised toys that demand sustained currents above the cell's design point.
