Super charger, but not exactly self-explanatory

I have only once by my old charged with the charger and batteries "refreshes" and lo and behold - almost all could be back on very good level of polish (nominal 2500mAh, actually loaded ~ 2100mAh, which is almost as good as new where)! Only one I have finally sorted out. And I'm talking about supermarket batteries from the past decade that have been always loaded with a supermarket charger and barely took power.
So I've saved with the device already by the first use of 30 costs for new batteries!

The device can therefore deliver what it promises. If one has to deal on the basis of the device with the function of batteries and chargers, we can understand why the usual fast chargers with high power input are not exactly good for most batteries. Since one must also wonder if manufacturers sell such devices bundled with batteries that are not suitable for long-term (formerly new battery buy = more sales).
Especially practical, I also think that you can control each charging bay individually. So it does not matter how many batteries you insert and whether these are completely different. If one considers the prescribed charge and discharge, is also produced no heat. The then to take longer, but is a pre-loaded replacement in hand could not care less.

The operation, however, is not self-explanatory, so you have to definitely study the BDA. And not only the first time! The requirement that the charging process starts automatically when you press a few seconds no button is initially a hindrance. If one is not afraid to take the BDA in the hand, you have the operation, however, quickly mastered (that's obviously the crux of many negative reviewers on the product page without batteries). Of the Eneloops I'm still not entirely convinced. They bring consistent performance and provide good their nominal value, for high-end requirements you need but maybe a little more capacity. But that is more my mistake - they ultimately deliver what they promise yes, so nothing goes past 5 stars.
