Can be charged anytime. * Can be rapidly charged with any quick charger smart chargers plug in charger or universal chargers * Batteries tested based on International Electronic Commission (IEC) standard to ensure capacity quality and life time so I am able to see the juice value in these batteries. When I first charged the AA's (slowly), I only got readings of between 900 to 1100 mAh. So I then refreshed the batteries (which can take days!!!) and got a maximum reading between 1821 -2360 mAh with an average reading of 2040 mAh for the 8 AA's so no where near their rated 2600 mAh. My new Sony and LaCrosse rechargeables charge to about 2600 mAh so I know the BC-9009 works okay.

Therefore, if you notice that the batteries aren't lasting after a charge you may want to refresh your batteries (that is discharge/recharge them a couple of times) to booast the mAh.

For the AAA's, after refreshing them I got a range of between 809 to 1101 mAh with an average reading of 911 mAh for the 8 AAA's.

So in summary (at least for the batch I got):

AA's are on average 2000 mAh (not 2600 mAh) which is about 80% of value.
AAA's are on average 900 mAh (not 1000 mAh) which is about 90% of value.

While the AAA's are close to the 1000 mAh, the AA's are way off the 2600 mAh.

So there is a trade-off of some mAh for these inexpensive batteries in that they wont last as long as better brands but some may find this okay given the cheap price.

In this update, I have increased my ratings by one star (from 2 to 3 star ratings) since my original review was based only on the AAs and I have now had time to refresh the AAA but I still take stars off for the misinformation about the mAh ratings.Before being put in a position to have to purchase rechargeable batteries we'd toyed with the idea with no real intention of actually jumping in and making this investment, we were wary about such an unknown and unpublished/unreviewed product.

Well, in 2010 I was in an auto accident which left me with a lovely permanent nerve/back injury and I was prescribed a T.E.N.S. Unit for the pain, which works fantastically, but EATS BATTERIES like there is no tomorrow.. so, I began researching rechargeable batteries, 9V specifically which is difficult to purchase in the stores by the way (go Amazon!, you always come through for us), and really couldn't find any concrete evidence that they were better than the consumable batteries.

SO, if you're toying with the idea, and teetering on the ledge of making this kind of investment and have any gadget that's eating your batteries I'll gladly push you off the battery buying cliff and tell you these are absolutely better than I'd ever expected. The Charge actually lasts longer than the standard run of the mill Energizer (consumable) and the standard Duracell (consumable), when you run low drop 'em back up on the charger and you're ready to go in a few hours, or less if you've invested in enough to switch them out. Bottom line, Tenergy rechargeable batteries while might be an uncomfortable and weary investment for the inexperienced is actually an absolute winner once you get into them. You'll never buy consumables again if you can help it!This marks the 3rd time I've completely replaced (recycled) and restandardized all the rechargeable batties in my house (the prior being the radio shack 1,400 mAh gold & black, followed by the 1,800 powder green white-tops & 2,000 metallic green black-tops). The new Tenergy 2,600 mAh powder blue black-top AA's seem to be the best rechargeable AA's available (as of this writing). With every generation, the run time of NiMHi's gets closer and closer to disaposeable alkaline batteries, and the blues are the closest yet. Not only do they have a deep charge, but they also seem to hold onto their charge, when not in use, better than earlier generations of batteries.

I use them in everything, and couldnt be happier ... and coupled with a Tenergy "Speedy Box" smart charger, I'm a doubly happy camper.These batteries cost half of what it costs for name brand rechargeables ON SALE. These were roughly $1.00 a piece. They are functioning as good as the name brands I own. I use rechargeables a lot, so I have had some experience with them. These are definitely worth buying. I've bought dozens of these over the past several years as well as dozens of their AAA's and a Panasonic charger from them. They have never delivered much juice and lose charge very quickly when stored. Now none of them will hold more than about a 10% charge. I'm sure a battery reconditioner would help considerably but I have been using the kit this company sold and it just isn't very effective. Will have to dump these and try another brand.
