My father is looking for charger that will solely be used for his Eneloops.
He got SC4 and for some reason he doesn't like using it, mainly because he find it hard to get them aligned in there.
+1 on the Powerex chargers. They have at least one model that offers quick charging. I have had two of their four-cell chargers for years and they are a solid value.
I have a Sony wall wart just like this. Even has a discharge or cell refresh function. Even now with much fancier chargers in the closet this is the one I grab 99% of the time for nimh cells.
There are similar chargers to the BQ-CC17 that charge much faster. Google Panasonic eneloop chargers to get to their website for them. I have an older model (which was then Sanyo) that does up to 2000mA (AA) and 800mA (AAA). So, charging only takes about an hour. Very fast, but probably a bit hard on the batteries, so I don't use it much. You might like something like the BQ-CC55 or BQ-CC65.
