Sanyo has developed a rechargeable battery that can be supplied to users ready to use, charged upon manufacturing so buyers don’t have to charge it before using. The new battery is a nickel metal hydride (NiMH) cell of the type commonly found in many portable electronics products but with a key difference. Typically, NiMH batteries lose charge over time if they are not used. Consequently, the gap between their manufacture and sale means it’s not feasible to supply them charged to users. Sanyo’s new battery losses energy much more slowly when unused so batteries can be supplied that are ready to use at the time of purchase. The battery technology, which will be used in an AA-battery will go on sale in Japan in November.
