The Best of Both Worlds The Best of Both Worlds

Make the Change to a Sustainable Lifestyle Make the Change to a Sustainable Lifestyle

Panasonic eneloop offers even longer-lasting performance than our dry battery products in a cell that you can reuse up to 2,100 times.
And with every charge, you’re not only saving on the cost of a replacement battery, you’re reducing wastage and actively helping create a more sustainable future.

Recharge Up to 2,100 times

Invest in a few packs of eneloop and you won’t buy another battery for years. A quick charge every now and then, and eneloop is ready to outlast a shop-bought alkaline cell, every time, 2,100* times over.

*Battery life based on testing method established by IEC 61951-2 (7.5.1.3). Varies according to conditions of use.



Save Real Money

Average homes use about 70 dry cells a year. Including charger and electricity, eneloop saves you about US$20 annually running just one game controller*. Before eneloop replacement, you’ll have saved hundreds.

* Based on a game controller with 4 x AA batteries playing for two hours per day for one year. Dry cell batteries total cost US$48.70 operated for 30 hours (24.33 purchases required/year). eneloop operation cost US$30.10 operated for 25 hours, with 29.2 charges required. Includes average cost of charger and electricity.

Make Your Household Green

Every time you recharge, you’re saving a spent battery from the trash, reducing your impact on the environment. Because they hold 70%* full charge after 5 years in storage, eneloop will be the last batteries you buy in a very long time.

* Capacity retention based on testing method established by IEC 61951-2 (7.3.2) when stored at 20 °C (based on Panasonic’s estimation) and compared with minimum capacity. Varies according to conditions of use.

Why Choose eneloop? Why Choose eneloop?

Panasonic eneloop lasts even longer than a regular dry battery on a single charge, yet you can reuse them for years. Here are the main reasons for making the change:

Six Key Advantages

Lasts Longer In Storage

By improving the metal-hydride alloy lattice, eneloop retains 70%*1 capacity even after 5 years in storage.

Recharge Up to 2,100 times

Each time you recharge, you’re saving on the cost of replacement batteries and reducing waste at the same time.

Longer Life per Charge

Stable voltage performance guarantees far longer life than conventional dry batteries even in extreme weather.

Durable in Extreme Climates

Maintains high voltage in temperatures as low as -20 °C*3—far longer than dry cells (great for skiing or hiking). Performance is also stable when stored above 40 °C.

Ready to Use Immediately

Pre-charged with sustainable solar energy at the factory and can be used immediately after purchase.

More Choice

The Panasonic product lineup comprises eneloop, eneloop pro, and eneloop lite to suit your application and budget.

*1 Capacity retention based on testing method established by IEC 61951-2 (7.3.2) when stored at 20 °C (based on Panasonic’s estimation) and compared with minimum capacity. Varies according to conditions of use.
*2 Battery life based on testing method established by IEC 61951-2 (7.5.1.3). Varies according to conditions of use.
*3 Operation time will be shorter than that at room temperature. Operating time varies according to equipment.
*4 As part of our participation the Green Certificate system, we use solar power to charge eneloop batteries prior to sale.

The Concept The Concept

People choose products that offer instant satisfaction even though the cost to our planet is sometimes high. But almost everybody would switch to a cleaner technology if it guarantees better performance and value without giving up convenience. This is what we set out to achieve with eneloop.
