Need more batteries like these.Review is for the Enitime AA:
----------------------------------
GS Yuasa is a Japanese company that makes batteries mostly for sport vehicles.
My Enitime AAs came pre-charged with my new universal remote control. "Technology from Japan - Made in China". So far performance is comparable with my other low discharge batteries.
Regular NiMh batteries are old school; these new batteries are greener and better.
Pros:
-For a rechargeable battery these batteries does not need to be charged before you use it for the first time; right from the packaging into your gadgets.
-They last a long time.
-Does not need special charger. You can use your existing NiMh charger.
Cons:
-This later technology is still expensive.
Other brands of low-discharged batteries are Eneloops by Sanyo Duracell Hybrid by Rayovac etc.

cheap but dont believe the AA's mAh rating!
Pros:
1. They are much much cheaper than others in the market.
2. Even if they are overrating the AA ones [see below] all that means that I will have to recharge them a little sooner. I am willing to take that over paying $ 3 to $4 per cell for other brands!!
3. AAA ones measure nearly 1000 mAh! They are rated at 1000 so they are good!
Cons:
I have a high end charger from Maha - MH-C9000 WizardOne Charger-Analyzer . It is able to tell exactly what the capacity of a battery is. I have tested at least 7 or 8 of my 25 or so Tenergy AA batteries. All measure around 1500 - 1600 mAh. Note that these batteries were bought in the last year or two. They are not brand new.
I even did many refresh cycles even after a couple of break-in cycles [that is supposed to recover under used cells] the capacity does not increase.
Hence I can say for sure....they are overrating them.
By the way my 3-4 year old energizer cells [2500 mAh] from Costco also test around 2000 - 2100 mAh on my analyser. So maybe age is a factor. But at least the energizers are closer to the 2500 they claim!

Finally - a rechargeable that I actually like!It's an on-going love/hate relationship. I really want to find a rechargeable battery that 1 - takes a charge and 2 - holds a charge. NiCads were not the answer because the capacity was too low they drained over time and there was that annoying "memory" thing. It looked like NiMH's were a good fix but I got ticked off that there was never any juice left when I went to use them. For a long time I used re-chargeable alkaline but if they drained to zero they were junk; also they stopped making them.
So here comes the Hybrid from Rayovac and I must say that I really like them. They take a charge and they hold it for a long time. Proof? - I have a high end flash for my DSLR. It uses 4 AA batteries. It takes a lot of juices to fire off a flash (FYI - it will illuminate the entire backyard at night and I have a big back yard!). One drawback of the big flash is the re-cycle time. When you shoot you do not want to wait for the unit to re-charge for the next photo. The answer is to always use fresh alkaline batteries but this is expensive and a waste. I was pleased that these Hybrids recycle faster than brand new alkalines (I was surprised at this) AND they can sit in my flash for months and still be ready to go when I need them.
Finally - someone has got it right!

WORKS GREAT!! FAST SHIPPING!I was very impressed with the shipping time (Although I did pay for expedited). Product was in great shape and was exactly as described.

Finally! Good rechargeable batteries.For many years rechargeable batteries (AAA AA C D) have been very disappointing because they "self-discharge" in a week or two while waiting to be used (or sitting on a store shelf). That's why you must always charge new batteries before using them.
These new Sony batteries finally solve the problem. They self-discharge very slowly keeping 90% of their charge after a year of storage. I have been using several AAA and AA Sony rechargeable batteries for a month now and am very pleased and impressed. I only wish that C and D cells were available.
