Panasonic AA Oxyride Alkaline Batteries, 1.5 volt, Pack of Four.

Panasonic's new, first-of-its-kind power cells, Oxyride Extreme Power, features the next generation in battery technology specifically designed for the digital era.

Representing the most significant developments in primary battery technology in 40 years - since the introduction of alkaline - Panasonic's new battery is more powerful and durable than alkaline, providing users of digital devices with a high-power, long-lasting energy source.

The new Oxyride is ideal when powering digital devices such as digital still cameras, handheld games, and portable audio products.

Indeed, test results show that the Panasonic Oxyride is now the best disposable battery for high-drain electronics like digital cameras and portable music players.

The New York Times conducted a digital camera test on the Oxyride Extreme Power batteries. How many shots a pair of Oxyride AA's can take in a digital camera versus the amount of shots a pair of alkaline AA's can take?

The test: 50 consecutive shots, alternating flash and nonflash, followed by 10 minutes turned off, so the batteries could rest. Then another 50 shots, and so on, until "Change the batteries" appears on the camera's screen.

The Oxyrides won.

The score:

Regular alkalines, 354 shots;
premium alkalines, 566 shots;
Panasonic Oxyrides, 844 shots, That's 2.4 times the life of regular alkalines.

Penny for penny, they deliver more power and, in power-hungry gadgets like digital cameras, last a lot longer than alkalines. In addition there is the added the convenience of more then double the amount of pictures per battery change and more rapid flash recovery time in digital cameras.

The Oxyride technology:
• The Oxyride battery uses newly adopted cathode materials (Oxy nickel hydroxide and manganese dioxide and graphite).
• Increased materials and a controlled mixing ratio deliver higher voltage and current.
• A new vacuum pouring technology enables the quantity of electrolyte in the battery to be increased, resulting in higher durability.

Considering that for almost forty years the battery industry has remained stagnant, while the consumer products that they power like digital cameras have evolved into higher draining devices, the powerful new battery technology from Panasonic is most welcome.

Low cost, primary batteries that can keep up with today's digital lifestyles provide great value and convenience and will certainly be greatly appreciated.
