Can anyone recommend a good battery charger for NiMH AA batteries? I'd like one which can take eight batteries but four is ok if it's an awesome charger. Ideally it would have the following: Decent charge speeds Battery capacity as a percentage Properly powers down once 100% charge is reached (my current chargers stop charging but the plugs stay rather hot) I quite like the look of the Youshiko YC5000 as it claims to have intelligent functions but I've never heard of them and it's only a four slot charger. It also looks rather similar to the 7 Day Shop DS-SC1000 at almost half the price? The Golisi S4 also looks pretty good? Also, is the battery refresh a good feature or just a gimmick? It is NiMH batteries which I'm charging.
