The Panasonic BQ-CC17 offers several real improvements over the Sanyo MQN06 4-cell charger, previously bundled with most eneloop packages:
- It can recharge each cell individually, instead of having to charge in pairs like most value chargers.
- It has 4 battery status indicators, one for each cell. (Note that those LEDs are hidden underneath the plastic case. They only turn green during charging)
The BQ-CC17 charges at 300mA average current, so it takes about 7 hours to fully recharge a set of 2000mAh AA batteries. It does not offer a fancy LCD display nor advanced functions such as 'Discharge'. But it does well on what it is designed to do: charging batteries. I have seen several cases where my batteries were over-discharged to 0V and cannot be detected by advanced chargers such as the La Crosse BC1000. The BQ-CC17, on the other hand, always detect and recharge those batteries reliably.
The Panasonic 4th-gen eneloop batteries are mechanically and electically identical to Sanyo 3rd-gen eneloop batteries (or 2nd-gen for that matter). The only difference is that the advertised lifespan is increased from '1800-cycle' to '2100-cycle'. But of course in real life, nobody can tell the difference between those two versions except by their wrappers.
The changer and batteries in this package are both excellent products. It is a great value if you can use all 10 AA and 4 AAA cells. Otherwise you should explore the option of buying the Panasonic BQ-CC17 Battery Charger by itself, and add more eneloop batteries as needed. If you are value conscious (read: cheap) like me, then you should consider the (white-label) AmazonBasics Rechargeable Batteries instead. Those are actually rebranded Sanyo eneloop cells according to my testing, but available at much lower cost.

There is now a Panasonic Eneloop package that contains the new BQ-CC55 charger, plus 8xAA and 4xAAA eneloop batteries. I consider it a great deal due to the better charger.
Do pay attention Panasonic makes 3 different chargers at least 2 of which look extraordinarily similar. This one is the Bq-cc17 Advanced
, (there is also the 2 circuit Bq-cc18 Basic and the Bq-cc16 SMART & QUICK
model – which I looked for quite a bit and it does not seem to be available in the USA as of October, 2014 I can not comment much on this model)
The cell do arrive charged and mine had ~80-90% charge straight out of the package, perfectly usable as the package was opened.
After researching rechargeable batteries, I found that many people recommend these, and they really have earned their positive reputation. These batteries outlast my previous controller batteries at least 3 fold if not more.
In comparison, my previous charging option was about 1000 MaH, where as these are about 2000 MaH per battery.
I would highly recommend this set to any gamer, as we tend to be battery eating fiends!
