Eneloop AA are specified for Fast-Charge at 2000mA (see its specs PDF), in 1.1hrs, which means that Sanyo/Panasonic lets you charge them with up to 2.0A.
cpf and Maha corp (and kreisler) recommend 1000mA; the cell will stay cool for the entire session.
check with 1680mA. if the cell gets warm, then it's not bad .. but heat itself does degrade a cell's quality (aging, capacity, LSD). Normal NiMH's would degrade by 2.0A and its produced heat (no doubt!), Eneloops not (robust!).
Just check the temperature and report back, thanks!! ( oh man, sometimes i can be real smarta$$ haha )
From what I've read, none of them is really good because they dont follow the NiMH charging algorithm like BC700 and similar do.. therefore I'd buy the MQR06 because its the fastest. ;)
Oh, and for that price, you can get a BC700. Oopsie. :P
i will suggest both chargers because they are priced similarly. If one uses exclusively Eneloops, then the MQR06 would be better imho. Because it charges faster!!
Actually the MQR06 follows correct charging algorithm for NiMH, with delta-V termination.
It also charges cells individually, and not in pairs. And here in Europe, MQR06 + four Eneloop XX bundle costs much less than the BC-700.
Then it maybe was one of the smaller.. but here in Germany, the price for MQR06 + four Eneloops is the same as the price of a BC700. But the BC700 is much more useful. :P
BC700 is superior to display-less chargers such as Sanyo, no doubt. My buddies a budgeteer that's why he declined the BC700. Chargers with display are quite fun to use btw!! And that's what our hobby is about:
Well, I haven’t seen any high quality cells suffer from just 1120mA, and if you’re charging 4 cells at once that current is halved, so it’s even less of a problem. :Р
