Good charger, lightweight and easy to store as you can fold the prongs out of sight; but there is a better charger from the same company. This is the MQN06, if you can find the MQN05 model which is very rare (usually just comes with an Eneloop power pack kit package), that is the model to get.
The MQNO5 charges each battery individually.
The MQNO6 charges in pairs. That means you cannot charge 1 or 3 batteries only. If you put 3 batteries, it will only charge 2 of them. If you put 1 battery, it will not start the charging process at all.
How can you identify the MQN05 from the MQNO6?
The MQNO6 has 2 LED lights at the bottom.
The MQNO5 has 1 LED light at the bottom.
I'm pretty sure I've reviewed these Eneloop batteries before but I use them so much and like them so much - I think they deserve another 5-star review!
I'm not sure what's NEW about these batteries, but they seem to be just as good as the previous Eneloops.
First, I've got about two dozen of these batteries in daily use. I've Never had one fail to take a charge and I'm sure I've cycled some of these well over 250 times.
I use them in remote controls, professional Nikon flash units, high powered LED flashlights (like the Fenix TK-40 which uses 8 AA cells) and many other applications.
I only charge them with this charger: Maha PowerEx MH-C808M Ultimate Professional Charger - available on Amazon. This model charges AAA, C, And D batteries as well. There is an AA-only model for a little less.
I think the charger is the key to long life. Some chargers keep charging or charge at such a high rate that they batteries overheat and fail prematurely.
Sanyo claims these batteries will hold at least 80% of their charge for a year. I actually tested this with two batteries. I brought them to a full charge and let them sit for a full year. Then I tested them with my tester (ZTS Multi Battery Tester - ZTS MBT-1). They both showed 80 percent. Most NiMh batteries would be totally dead after sitting for an entire year.
Note: if you want to test NiMh batteries accurately (along with many other battery types) get this charger available at Amazon: ZTS Multi Battery Tester - ZTS MBT-1. It's the best by far.

NOTE: I originally wrote this in July. It's quite possible that, by now, Amazon IS shipping 3rd gen Eneloop batteries. I just wanted to make it clear that this review MIGHT (or may NOT) be out of date! I simply don't know for sure.
1 star because, twice now, I've received these batteries from Amazon, and both times they sent me different batteries from what was advertised!
Amazon claims that these are the NEW eneloop batteries. I've even seen some reviews confirming that these are the 2nd generation eneloop batteries. The thing is, the 2nd generation eneloops are the OLD batteries. The "NEW" eneloop batteries are the THIRD generation batteries.
eneloop makes it as easy as possible to tell exactly which batteries you're buying, because their model numbers contain all the information you need! The model numbers of their standard batteries use the following format:
where "#" tells you the type of battery:
# = 3, AA batteries; # = 4, AAA batteries
and "X" tells you the generation:
X = blank, 1st generation; X = A, 2nd generation; X = B, 3rd generation
eneloop's blister packs simply add the number of batteries in the pack, followed by "BP", to the model.
So, a 16 pack of eneloop NEW AAA batteries is:
Easy, right?!? EXCEPT, Amazon has REMOVED the generation indicator from the model numbers!!!
The 8 AA pack in this listing is model number "SEC-HR3U8BPN". Sure, there are extra letters at the beginning and end, and the dashes are different. What matters to me is that the "TG/TGA/TGB" section is missing!
And so they label these as "NEW" batteries, but send you the old ones!
To make matters worse, don't think that asking Customer Service will help! When I sent back the first set, I wrote to them, specifying that, if they were just going to replace them with the same batteries, DON'T! Well, that didn't work so well.
To be clear, eneloop makes fine batteries, including their 2nd generation! That's not why I gave these 1 star. Had Amazon listed these as eneloop 2nd gen batteries, I would have rated them four or five stars. But they didn't! They listed these as something they're not, and THAT deserves a rating of ONE STAR!
