AVACOM ALF-2 USB Battery Charger for Li-Ion 18650 and Ni-MH AA/AAA Batteries

AVACOM ALF-2 — Universal Battery Charger

Users of various battery types will appreciate a charger capable of reliably and safely charging a wide range of cells. The AVACOM ALF-2 handles Li-Ion, Ni-MH, and Ni-Cd batteries with a charging current of 500 or 1000 mA, ensuring fast and efficient charging. Thanks to its microprocessor-controlled system, it automatically adapts to the battery type, detects its condition, and protects it against overcharging, short circuits, or overheating. An ideal choice for those seeking a compact and versatile solution.

Intelligent Features for Various Battery Types

The AVACOM ALF-2 supports charging 1-2 batteries simultaneously and automatically identifies whether it is charging 1.2V Ni-MH/Ni-Cd or 3.7V Li-Ion cells. Minus-Delta-U termination technology ensures precise charging cutoff for Ni-MH/Ni-Cd batteries, thereby extending their lifespan. Zero-voltage activation allows for the safe charging of Li-Ion batteries equipped with protective circuitry—a key factor in maintaining their optimal capacity.

Safety and Charging Status Indication

Safety is a priority; the charger features protection against overcharging, short circuits, overheating, and reverse polarity, keeping both your batteries and the device itself secure. LED indicators provide clear information on the charging status: a red light indicates that charging is in progress, a green light signifies a full charge, and a flashing red light indicates a faulty battery. Thanks to this simple indicator, you always know the status of your batteries. ### Technical Data and Compatibility
