Disposable and rechargeable batteries contain heavy metals such as mercury, cadmium. According to estimations Only in US 3 billion batteries are discharged in a year. Small amounts in each battery can really add up. Probably you understand that using rechargeable batteries you can help the Earth.
A new kind of batteries is coming in. Called earthCell the battery is low self-discharge nickel hydride, with a much longer shelf life than regular NiMH batteries and longer run times than alkalines. It can be used like disposables, except that users send them away for recharging or recycling when they’re dead. Staff at earthCell test each used battery arrives from the customers.
Each battery can reportedly be recharged hundreds of times. If the battery is just too used up, it will be dismantled, so that its materials can be used to create new batteries. “Our batteries are essentially rechargeable batteries,” said earthCell founder Jason Rugolo. “They can be recharged at home in LSD NiMH chargers. Our understanding is that the vast majority of people out there don’t want to manage their battery stock, perhaps because batteries are an insignificant part of peoples’ lives.”
Rugolo is presently in the process of raising funds for his business, on Kickstarter. A pledge of US$13 will get you four AA and four AAA earthCell batteries, along with a mailer. Higher amounts will get you more, with pledges of $45 or over paying off in 10 AA’s and ten AAA’s.
Projected retail prices for the batteries haven’t been announced yet, although Jason has stated that they will be a much better value than disposables. So far, earthCells will only be available within the U.S.
