Opus BT-C700 Intelligent Battery Charger
The product is intended to charge and discharge NiCd or NiMH rechargeable batteries. It provides four independent charging slots for AA / AAA rechargeable batteries. The charger can also optimize and test the maximum capacity of the rechargeable batteries. Each charging slot has its own display to show various information, such as charging current, battery voltage, charged capacity, battery internal resistance and elapsed charging time.

The charger can charge batteries of different type and size and with different capacity at the same time. It also integrates the minus delta voltage ( -ΔV ) function, which monitors the voltage over the charging cycle. When battery is fully charged, the charger will switch to trickle charging automatically. Therefore the battery will be kept at its optimum capacity. The charger also includes overheat detection to protect rechargeable batteries and charger itself from overheating.

    Отличная бюджетная зарядка для Ni-MH аккумуляторов
    Отличная зарядка для никеля. Версия прошивки 2.1. Имется бела подсветка экрана. В комплекте блок питания на 12 вольт. Устройство может Разряжать, заряжать, проводить тест ёмкости, восстанавливать ёмкость (прогоняет 3 цикла заряд-разряд) и показывать внутреннее сопротивление тестируемых элементов. Определенно советую к покупке, За свои деньги великолепное зарядное устройство, круче только махи и лакроссы по цене 1.5-2 раза дороже.
    Режим восстановления хотелось бы поумней, как в лакроссе, чтобы прогонял циклы до тех пор, пока ёмкость не перестанет повышаться. Но и тот, что имеется наглядно восстанавливает чуть подуставшие элементы.

    Отличное з/у для никель-металлгидридных АКБ. Хорошее соотношение цена-функционал. Режимы: заряд, разряд, восстановление (разряд-заряд - 3 цикла), тестирование, быстрое тестирование (определение внутреннего сопротивления АКБ). Возможность зарядки высоким током (1000 мА, правда, только на 2-х слотах из 4-х). Имеется подсветка. Комплектация: З/у, адаптер питания 12В и инструкция по эксплуатации на английском языке.
