Sanyo eneloop rechargeable batteries going big

Dull but worthy – clean, green tech can make a difference

Now that we know Sanyo is on the side of good in the battle for the future of the planet, we're happy to bring news that its well-respected eneloop rechargeable batteries are finally going mainstream.

The long-life eco batteries go on sale in Japan next month in two new flavours. Standard C and D cells join the existing AA and AAA line-up there on 12 September, with a worldwide launch coming soon after.

It's worth it, you know

As we well know, the eneloops come pre-charged and can stay juiced for over a year. Not only that, but they can be recharged up to 1,000 times, which makes those late-night battery runs for the Wiimote a thing of the past.

At the same time, Sanyo plans on introducing a universal charger that tops up the eneloops from the mains. Pleasant white styling and simple charge indicators are most welcome.

Although it's not the most earth-shattering tech news we've ever reported, better rechargeables make sense for both your pocket and the planet.
