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

Panasonic eneloop can be recharged up to 2,100 times—top them up whenever you want and in a couple of hours they’re ready to work longer than standard alkaline cells. They even hold 70 %*2 of a full charge after 10 years*3 in storage, so you can count on them in an emergency.

Save Real Money

Studies show that an average household with two kids uses about 70 dry batteries a year. Even when factoring in the charger and cost of electricity, switching to eneloop saves a heap of cash in the long run. For example, in one year you could save almost US$20* just on the cells needed to run a single game controller. Plus, you’ll always have batteries on hand, even when the shops are closed.

* 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 $30.10 operated for 25 hours, with 29.2 charges required. Includes average cost of charger and electricity.

Make Your Household Green

Every recharge saves a battery from the trash. You’re joining millions of others around the world in reducing waste, and making a real contribution to the future health of our planet.
