They can be recycled free of charge at any of the 50,000+ Rechargeable Battery Recycling Corporation (RBRC) recycling centers near you.

SANYO eneloop Technology - For more than 35 years, SANYO has been a leading manufacturer of rechargeable batteries. With its longstanding heritage as a battery technology leader, SANYO’s new eneloop batteries utilize the latest rechargeable battery technology allowing them to last even longer than before. Typical rechargeable batteries exhibit a “memory effect”; a term used to describe the effects on the overall life of the battery when it goes through charge and discharge cycles. SANYO eneloop batteries represent a key innovation in that they exhibit an extremely low rate of self-discharge, which means they can hold their stored energy for a very long time. New chemistries and advancements in technology allow SANYO rechargeable batteries also outperform alkaline in many high power drain and low temperature applications.

eneloop Concept:

The "eneloop" battery proposes a new product concept as "a lifestyle promoting the change from single-use batteries to rechargeable". The "eneloop" battery has been popular since its release in November 2005. .

SANYO supports a wide range of user needs by offering a variety of "eneloop" related products. In addition to AA and AAA size "eneloop" batteries, SANYO has a line up of C size/D size battery adaptors (spacers) which enable users to use a AA size battery as a C size/D size battery, battery chargers compatible with two/four AA or AAA size batteries, rapid chargers and a solar charger.

SANYO will continue to promote the concept of "single use to rechargeable" by offering a variety of battery-related products for many more users through our accumulated battery and charging technologies.

Comparison of remaining capacity over time

SANYO eneloop compared to regular rechargeables
1 Estimated battery charge when stored separately (not installed in a product) and kept within a temperature range of -4 to 86 degree Fahrenheit.

eneloop lasts longer in comparison with dry cell batteries

Key advantages of Ni-MH batteries are still inherent in eneloop:g
for example, superior performance in digital cameras (four times more shots than with alkalines) and the excellent stability even at low temperatures, for example while skiing.

And eneloop can be charged with virtually all modern chargers for Ni-MH batteries.

   An eneloop battery may remain up to 75% charged if not used for up to 3 year
   *Estimate based on test results for battery life according to standard JIS C8708 (4.4.) Actual results may vary according to use.
5. Do eneloop batteries fall under the new airline travel guidelines for lithium batteries?
   No. The chemistry that eneloop batteries use is Nickel Metal Hydride. eneloop batteries are not lithium and therefore do not fall under the new travel regulations for lithium batteries. For more information on traveling with lithium batteries, please go to http://safetravel.dot.gov.
6. Does temperature have an effect on their performance?
   Yes, temperature does have an effect on eneloop's performance. If it is too hot, the high temperature could cause the battery to discharge at a more rapid rate. On the other hand, eneloop works better than alkaline, and other rechargeable batteries in freezing temperatures!
7. Do I have to charge 4 batteries at a time in the 4-position charger, or may I charge only one?
   The eneloop 4-position charger battery slots are designed in pairs. It is designed so that it may accommodate charging 2 batteries at a time - 2 in the inside positions or 2 outside positions - or 4 batteries at a time. The charger charges AA or AAA only.
8. On the 4-position charger does it matter which slot I place the AAA battery into?
   You may charge AAA batteries in any of the 4 slots. It is recommended to charge them in pairs - 2 on the inside slots or 2 on the outside slots – or 4 at a time.
9. How long does it take to charge an eneloop battery in the eneloop 4-position charger?
   From 4 to 7 hours.
10. Can the 4-position charger be used world-wide?
    If you have the 4 position charger (Model # MQN05) with the sliding cover, then no. The new 4 position charger (Model # MQN06) does have world-wide voltage. You will need to purchase adapters to convert the plug to international standards.
11. How long does it take to charge an eneloop battery in the eneloop 2-position compact charger?
    From 2 to 4 hours.
12. Can the 2-position compact charger be used world-wide?
    Yes, the compact charger has world-wide voltage. You will need to purchase adapters to convert the plug to international standards.
13. Can I use a "Quick Charger" to charge an eneloop battery?
    Though it is possible to charge an eneloop battery in a "Quick Charger", it is not recommended. We recommend charging eneloop batteries in a NiMh charger that is 2 hours or more. Charging eneloop batteries in a "Quick Charger" can reduce the overall life of the battery. It is strongly recommended to use eneloop, GE/Sanyo or Sanyo NiMh battery chargers. We only warrant eneloop if used with an eneloop, GE/Sanyo or Sanyo NiMh battery charger.
14. Will my eneloop battery charge in any other charger other than the eneloop charger?
    It is strongly recommended to use eneloop, GE/Sanyo or Sanyo NiMh battery chargers. Most NiMh rechargeable battery chargers may be used to charge eneloop, however we only warranty eneloop if used with an eneloop, GE/Sanyo or Sanyo NiMh battery charger.
15. What is the number of charger/discharge cycles I can expect from the eneloop battery?
    eneloop may be charged up to 1,500 times*.
    *Estimate based on test results for battery life according to standard JIS C8708 (4.4.) Actual results may vary according to use.
16. Can dropping the battery cause damage to it?
    Yes.
17. What does mAh stand for?
    The (mA) stands for milliamps. The (h) stands for hour. This rating is in regards to the life of the battery, similar to the gas tank in your car.
18. What does the terminology "memory effect" specify?
    Memory Effect is a term used to describe the effects on the overall life of the battery when it goes through charge and discharge cycles. The eneloop battery does not experience the effects of "memory effect".
19. Should I store my batteries charged or uncharged?
    If stored with charge, it is possible that when you return to use the battery there may still be some charge left in the battery, therefore it will enable you to use it right then and there. Also, by keeping some charge in the battery, it will require you to "cycle" the battery fewer times until it reaches its peak charge. If you store them with no charge, you will have to "cycle" the battery multiple times until it reaches its peak charge.
20. Will the eneloop battery work with Nintendo Wii remotes?
    Yes, the eneloop battery does work with the Nintendo Wii remotes. In fact they are a perfect fit for one another. They also work with any other type of remote that requires an AA or AAA battery.
