I bought this charger replacement of a standard charger in which the batteries seemed overly warm. It allows, which is very important to avoid the memory effect of Ni-MH batteries, discharge them before recharging with 3 charging current settings. The batteries are individually loaded and the display is very convenient to see where the load. I do not regret this purchase at all, instead I recommend to optimize the life of batteries. Small problem which is why I withdrew a star, the control buttons do not always react the first time.
