From the Manufacturer
With normal rechargeable batteries it made sense to charge them just before you wanted to use them. Otherwise, there was too much risk that the battery would not provide full power when needed due to degradation of stored power. Therefore there was a checkpoint on every vacation checklist: Charge batteries. Then the endless wait until the batteries are finally charged...even the most advanced and most expensive chargers typically take at least 15 minutes. This can be very long 15 minutes, if the taxi is waiting at the door.

Now you can forget all this. Charge the eneloop, whenever you have time for it and store them. The extremely low self-discharge of eneloop batteries saves you from all the charging stress.

When you use eneloop in your houshold equipment, spend some extra money and purchase a set of spare eneloops. Keep these spare eneloops stored in a charged state and you will always have fresh batteries at hand whenever you need them!

More Features Than Typical Ni-MH Batteries

The main advantages of Ni-MH rechargeable batteries exist also in the eneloop:

• Approximately 4 time more shots than with alkaline batteries
• High performance even at low temperatures (down to -5 °C) during your winter vacation
• Rechargeable and therefore cheaper on the long run

Given these advantages, there are however also some disadvantages to typical Ni-MH batteries which made consumers reluctant to exchange their disposable batteries for rechargeables:

• After purchase, rechargeable batteries have to be charged before they can be used.
• Rechargeable batteries lose stored energy quickly
• Continous/frequent charging ( without conplete discharge ) can destroy the battery
• The charging process can take a long time and rapid chargers are expensive

All these negative attributes have one root-cause: self-discharge. Self-discharge means that a charged battery slowly discharges itself without any equipment consuming any current. This is the reason for rechargeable batteries being sold in a discharged state. And this is the reason that keeping charged batteries for some time did not make any sense--When you needed then, the energy was gone.

Immediate Use Like a Disposable Battery

Because the eneloop has a very low self-discharge, Sanyo can ship the batteries to retailers in a charged state. This means the consumer purchases a charged battery, which can be used immediately. The eneloop is therefore as user-friendly as any disposable battery.

Customer Reviews

Great for digital cameras
I was using NiMH AA batteries in my digital camera. I charge them, put them in the camera, maybe a week or two would go by and I'd grab the camera to take a photo and the batteries were dead. I have not had this problem with eneloop batteries. Shame they are not available locally.

these batteries remain charged and reliable
These are the only batteries I can use with my digital camera.
Other rechargeable batteries I have tried (SONY) must be charged right before usage (which takes a few hours). This greatly restricts how I can use the devices that need them. I don't plan ahead 8 hours before I use my digital camera. Taking a picture should be a spontaneous event.

Slight Adapter Design Flaw...
I haven't had these batteries long enough to judge their life per charge, but so far they seem to be doing really well, so no issues there.

My problem is with the D (and possibly C) spacers (adapters) that come with these batteries. I purchased these mainly for use in flashlights, and other regularly used items. To my dismay, the D spacers do not work in my Mag-Lite 3 cell (D) flashlights. I'm sure this is going to be an issue with other flashlights as well. A normal feature of flashlights, is the coil/spring that presses against the batteries and completes contact when the flashlight is closed. An important aspect to this is that the spring needs to be able to press against the actual batteries. Unfortunately, since the spacers are shorter than the AA batteries, and they're open at the top, the spring simply goes over and around (never touching) the end of the AA battery. It then pushes on just the plastic spacer, causing no connection, so the flashlight doesn't work. The only way to fix this, is to put a coin or metal disk on top of the AA battery, and then close the flashlight. Doing this makes the necessary connection and the flashlight works.

[...] Flashlights have been around for years, and so has the existence of these springs, so in my opinion this is really bad designing.

I hope Sanyo corrects this with future adapters, since these can really be useful batteries. I shouldn't have to amateurishly rig a flashlight to get it to work. They should have realized that the bottom of a D battery has a larger surface area, and many products are designed with this in mind. Since they didn't take that into account, the small surface area of the AA battery, is a pretty big issue.

If you won't be using the D adapters in flashlights, then you probably won't have a problem. Like I said, so far the batteries are performing very well. I just wanted to make everyone aware of something I didn't think of, and never would have thought of, prior to purchasing.
