Panasonic has introduced a new generation of alkaline batteries that boast 33 percent longer life than the company’s regular alkaline cells.

Its new Platinum Power AA and AAA batteries employ the company’s eight-year-old Evolta technology, and feature a combination of high-purity manganese dioxide, a titanium additive and an ultra-high-density cathode filling to extend their useable life.

The new battery tier also boasts a triple-coated negative terminal with an iron-nickel alloy layer that prevents rust and reduces contact resistance to ensure steady energy flow.

In addition, the Platinum Power line offers increased protection from leaks thanks to a new zinc alloy, electrolytes and organic inhibitors that reduce gas build-up with the cell. A new, more resilient gasket material, plus a specialized sealing method, further reduces the possibility of electrolyte leakage.

Yoji Takagi, sales and marketing director of Panasonic Energy Corp. of America, said the batteries are optimized for high-drain devices like game controllers, radio-controlled toys and flashlights.

The cells are available in four- to 48-cell multi-packs with a suggested retail of $4 for a AA four-pack, and can be stored for up to 10 years.
