Product Description

The classical advantages of rechargeable batteries are: high performance, especially if high discharge currents are required ( like in digital cameras ) cheap in use, because they can be recharged many times; environmental friendly, because one rechargeable battery replaces 1000 disposable batteries; good performance at low temperatures. A special feature found in eneloop batteries from Sanyo is an extremely efficient (low) dormant discharge rate. That means, when not used, the charge is retained for long periods. Of course you (and we) recommend using these batteries over and over/ Just in case you don't, you can be assured the battery will retain up to 85% of its charge over the course of a year.Because the eneloop has a very low self-discharge, SANYO can ship the batteries in a charged state so they're ready to use out of the pack. In contrast to a disposable battery the eneloop can be charged 1000 times. This saves the environment and your purse. Thus one eneloop saves the waste of 999 disposable batteries. Even if you consider the slightly higher cost of the eneloop compared to a disposable battery and add the cost for the charger and the energy consumed by the charger, the investment for one eneloop returns easily after a few charging cycles. Imagine how much money you have spent for batteries in your life. Now there is an end to this spending!

From the Manufacturer
Why Sanyo eneloop?

Sanyo eneloop rechargeables can replace an entire kitchen drawer's worth of dry cell batteries

You already know the benefits of using conventional rechargeable batteries. But Sanyo eneloop batteries have advantages over other rechargeables that put them a step ahead.

Sanyo eneloop batteries are an excellent choice for your rechargeables because:

• They can be used right after purchase
• They consistenly yield high performance
• They have a long shelf life with no loss of energy
• They can be used everywhere
• They are environmental friendly

Self-Discharge: Why Conventional Rechargeables Don't Cut It

Conventional rechargeable batteries have numerous advantages that make them great to use for your portable electronics. But they also come with certain disadvantages. After purchase, rechargeable batteries have to be charged before they can be used. And once charged, rechargeable batteries lose the stored energy rather fast. The charging takes quite long and rapid chargers are expensive. Not only that, but continuous charging or frequent charge to "top off" the lost energy (without complete discharge) can destroy the battery.

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 them, the energy was gone. Sanyo eneloop batteries have an extremely low rate of self-discharge, which means they hold their stored energy for a very long time--charge your batteries once and put them in your kitchen drawer, and over a year from now you'll still be able to use them right away, without needing to charge them again.

Under the Hood: How eneloop Controls Self-Discharge

How can the self-discharge in the eneloop be so reduced? The self-discharge of Ni-MH batteries is caused by three main reasons:

• The chemical decomposition of the cathode
• The natural disaggregation of the anode
• Impurities of the anode

The chemical decomposition of the cathode has been reduced substantially by the use of a new hydrogen-absorbing superlattice alloy. As an additional benefit the superlattice alloy increases the electrical capacity of the battery and reduces the internal resistance, which allows higher discharge currents than conventional rechargeables. Also, the anode has been strengthened by the improvement of the electrolyte composition, which reduces the natural decomposition by increasing the oxygen over-voltage.

This gives eneloop batteries a number of advantages over traditional alkaline batteries, including up to four times more power when used in a digital camera, high performance even at low temperatures (down to 23 degrees F) during your winter vacation, and a vast cost savings in the long run. The eneloop advantages are even more glaring when compared to typical NiMH batteries: not only are they ready for use right out of the box, but they generally last longer than most NiMH batteries (continuous and frequent recharging can destroy other NiMH models) and save both time and money (traditional NiMH charging is slow when you're in a hurry, while rapid chargers are expensive). All told, you can recharge eneloop batteries up to 1,000 times without experiencing a "memory effect"--just charge the amount you need and you're set.

Customer Reviews

These batteries are UNBELIEVABLE!
I used these in my son's radio controlled car. Regular Duracell AA batteries used to last no more than an hour in that car. I've been using these batteries for 3 days now, probably 3-4 hours of use and they show no signs of requiring a recharge yet! VERY HIGHLY RECOMMENDED!!

Good Batteries
I've only had these batteries for about 2 weeks and they've exceeded expectation. I use a Sony ICD-P520 Voice Recorder everyday to record about 3 hours of lecture. I usually have to change out a pair of regular Alkaline Batteries after about 12 hours (4 days) of usage. These Eneloops have lasted just as long as Alkaline Batteries, maybe a little longer, WITH the additional aspect that they are rechargeable. Highly recommend these batteries for those who use AAA frequently; they will pay for themselves after a couple charges.

Great rechargable batteries
These batteries work well and come pre-charged as described. Because they don't lose their charge when not in use as quickly, they can be used in other devices that you normally wouldn't use rechargeable batteries with, like led flashlights and wall clocks. They work great for everything that takes AA batteries. After a few charges you've already saved the purchase price by not using alkalines'.
