Eneloop combines the performance and convenience of dry batteries with the eco-friendly efficiency of rechargeable batteries. Every time you reuse eneloop, you're not just saving money. You're also helping to protect our planet.

The best of both worlds

Recharge up to 2100 times*

Every time you reuse eneloop, you're saving on the cost of replacement dry batteries and reducing waste. Your investment pays for itself over the life of the product, and you'll feel great about doing your part for the earth.

Retains 70%* after 10 years

We've improved the metal-hydride alloy lattice inside your eneloop battery so that it retains 70%* capacity even after 10 years in storage. The design also resists voltage drop during discharge and minimizes loss of capacity. Once charged, you can trust eneloop to work just like a dry battery, and its long storage life is great in emergencies.

Better discharge performance

A battery is like a tube of toothpaste. You can squeeze it in the middle or roll it up carefully from the bottom. Dry batteries squeeze out a large flow of voltage that drops away quickly. By contrast, the voltage from eneloop flows out steadily for longer, right up until the battery is depleted. This means your devices work reliably, and you use more of the energy in the battery. Devices powered with dry batteries, on the other hand, might stop working before the batteries are completely flat because they can't get enough voltage.

A deeper reserve of power

A digital camera equipped with eneloop can take 4.4 times* as many shots before running out as a digital camera equipped with standard alkaline batteries. Enjoy longer battery life and better device reliability between charges with eneloop.

Lasting power in a wide temperature range

Your eneloop batteries maintain excellent discharge performance even when used in heat and cold. The batteries are rated for use in temperatures between -20 °C and 50 °C, which is great for outdoor activities such as skiing, hiking, photography, and camping.

Works better in cold weather

All batteries rely on a chemical reaction to discharge power, and freezing conditions can slow or even stop these reactions. Your eneloop battery is more resistant to the effects of cold and can work in temperatures as low as -20 °C. Use your devices with confidence wherever your day takes you.

Pre-charged with solar energy and ready to use

Before eneloop batteries are shipped, they're charged with solar energy at the factory as part of our participation in the Green Certificate system and the Panasonic Environment Vision 2050 initiative, where our company aims to generate more energy than we use by 2050. Of course, pre-charging means you can use eneloop immediately after purchase.

Made in Japan

eneloop is designed, manufactured, and tested in Japan to rigorous quality control standards and is available in about 70 countries* around the world. Use with the confidence that comes from products made to the highest standards of Japanese craftsmanship.

Works in a variety of devices

While eneloop has a slightly lower voltage than equivalent dry batteries, it works better in almost any device where standard batteries are used. From low-drain applications in computer mouses to high-drain equipment such as camera flashes, toys, and RC cars, its high capacity and stable discharge voltage will power your gear more reliably and for longer than most single-use alternatives.

Recharge anytime you want

Unique battery and charger technology suppresses the memory effect in eneloop batteries, which means you can top them up anytime without reducing their capacity. To avoid the memory effect with other rechargeable batteries, you may have to run them flat before you can recharge, which isn't always practical. With eneloop, you can recharge whenever you want without worrying about reduced battery life.

Save real money

Yes, your eneloop batteries and charger cost more than a pack of dry batteries. But you save a lot more in the long run. For example, powering a single game controller with eneloop is almost US$20 a year cheaper than using dry batteries. It's easy to see how the savings add up if you switched all of your battery-powered devices to eneloop, since you can reuse each battery up to 2100 times*.
