(1 stars) - Very rapid discharge
These batteries are supposed to retain their charge for years. I charged mine up, and two days later...dead. Retains no charge over time. Perhaps I received a defective set.

(5 stars) - GREAT batteries for slow-drain devices.
I'm not an expert or battery afficionado like NLee the Engineer (whose reviews on batteries and charging accessories have been surprisingly useful to me!), but even the layperson can appreciate Sanyo Eneloop batteries. In short -- great purchase for use with slow-drain devices. Details below:

I've used the Energizer NiMH rechargeables for several years now -- in my Xbox controllers, remote control, mouse, keyboard, some flashlights... and so on.

I noticed that in some devices they were great, but that in low-drain ones like my remote control or mouse I was recharging way too frequently -- once every month or two. Some research revealed that typical NiMH batteries have great capacity, but lose a lot of their charge after they sit around for a while (1-3 months will kill a lot of the charge in the battery, even if it's not being used).

This wouldn't be too much of a problem except for the fact that NiMH cells only have a native voltage of 1.2v -- already low for some devices. Combine the lower voltage with charge that dips over time and you have a shorter than reasonable lifespan.

Enter eneloop batteries!

I started off with I think 8 AA cells and have now expanded to 16 AA and 8 AAA eneloop cells. I use them in my mouse, remote control, keyboard, and Xbox 360 controllers. They're great and last just as long as normal alkaline cells! Definitely a worthy purchase for those frustrated by frequently switching out their normal NiMH cells in low-drain devices. Now, I use my normal NiMH cells in high-drain devices like flashlights and let me eneloops do the long-life work in my low-drain devices.

(5 stars) - Best Batteries Ever
These batteries are the best. I will never use any other type. They hold a charge better than any other rechargeable battery I have ever used

(5 stars) - Finally.... a rechargable that I'm satisfied with.
I've been using Eneloop batteries for about a year now and am really happy with them.

I initially bought them to use in camera flashes (Canon Speedlite 580 EXII). I wanted something rechargeable because I'd be going through a lot of batteries and I wanted something that held its charge a long time because there might be long periods of time before I use a flash. They have performed as advertised. They are long lasting and hold their charge a long time while waiting in my camera bag.

I've gradually replaced all the AA (and AAA) batteries in my house with these as my old batteries have died. It is great to know that I don't have to buy new batteries for all my remotes, Wii controllers, flashlights, etc.

I felt vindicated when I read Consumer report's positive ratings for these batteries.

(5 stars) - SAVES YOU MONEY
I purchased the starter kit for the eneloop batteries over a year ago, and even after heavy use from my little girl's toys and my camera and calculator...etc. etc. they are still going strong. They recharge quickly and last a long time without recharging. I would estimate I've probably saved hundreds of dollars with these babies...they're awesome.
