this charger has nothing to do with 3 chargers spetits fifty francs. it does not heat the batteries, it detects when the maximum load is performed, and can even rafaraichir old batteries properly. you can adjust the load 200/500/700, and it is better to stay on 200 if you're not super préssé.
obviously it vautplus than a simple charger, but if we want to have always ni-mh batteries properly charged and top, no such thing. reflexophile device essential for any self-respecting. certainly good material.
