An MSNBC technology article reported that the new Panasonic “Evolta” Double-A (AA) battery is the longest lasting household alkaline battery â€” according to Guinness World Records. The double-A sized battery is used in many household items from gadgets and toys to clocks and tools. The article states that the improvements are made by packing in more material with a better seal.
They were tested against the famed bunny’s ‘Energizer’ and the well known ‘copper topped’ Duracell. The new ‘Evolta’ batteries were also pitted against Panasonic’s own ‘Oxyride’ branded battery, both which are made by Matsushita Electric Industrial Company (makers of Panasonic branded products). The tests were performed using the guidelines of the International Electrotechnical Commission and the conclusion was that the ‘Evolta’ will last 20 percent longer than other household alkalines. These new batteries will have a shelf life of 10 years and cost about 3% more than the Panasonic ‘Oxyride’ batteries. Keep your eye out for them and perhaps run a private ‘real life’ test when they become available later this year?
