In normal use batteries last approx 12 months, the modules offer much better battery life performance than the old 70's types.

Customers in Australia, Asia (excluding Japan) and Latin America who are eligible should contact their local Asian Pacific or Latin American Apple Authorized Service Provider to obtain a replacement battery.

For safety reasons, the battery recall program requires the return of the original battery before a replacement battery can be sent. Therefore, we are unable to ship the replacement battery prior to receiving the recalled battery.

One cycle of a battery is a discharge from full charge to full discharge and a return to full charge again. The total number of cycles a battery can perform before failure is called its Cycle Life. Most battery manufacturers will not discus the Cycle Life of their product. Many advertised Deep Cycle batteries have not been tested, or, which is the case with cranking batteries, were never designed for long Cycle Life.

The battery option include a rechargeable lead acid battery with a useful life of 5 years and two non-rechargeable battery configurations are available with a minimum life of 5 years.

It's a fact. Let's consider how a typical MP3 player works. In a MP3 player, at least 70 percent of the battery power goes to running circuitry that produces the audio output for you to listen. As the battery power is drained. The audio signal is the first thing that diminishes. When this happens, you have to crank up the volume to make up for that loss, and then audio quality becomes more distorted. However, turning up the volume on your player also drains the batteries faster.

This article is from the NYT: April 6, 2006 Helping Batteries to Keep On Going and Going By PETER WAYNER What good is a tiny thin sliver of electronic gadgetry if the battery dies in your pocket after a few minutes? Not much, and now that manufacturers have mastered the building of pocket-sized wonders that are often too small for our fingers, they are starting to pay closer attention to battery life. New machines come with smarter batteries and miserly circuitry that works longer.

There are three battery technologies in common use these days. Each of these battery technologies has its own unique properties and its own peculiar charging requirements. Here is a summary of those available technologies: This is the oldest of the three technologies, but you will still find quite a few batteries of this type still around. Cadmium is extremely toxic, and so this type of battery has been slated for extinction in the near future.

Due to the RadDetect's unique air sampling of 32,768 times each second (this enables the Directional feature and instant alerting feature), the inexpensive user-replaceable battery should last more than 6 months under normal use.

These batteries were used to power Minox C4 flash cubes, Vitessa 500AE cameras, Agfa Rapid cameras, Agfa Agfamatic 126 cameras, Kodak Instamatic reflex cameras and many others. If your application requires two PX825s in a 3 Volt stack, then you are in luck. We offer the three volt PX30-L. It is the modern equivalent of the PX30 battery that was composed of a stack of two PX825s. If your application requires a single PX825 the best solution will be a 357 or SR44 1.

The average is 5-7 years depending on the duty cycle and more importantly how well it is maintained. We have long term customers, proprely maintaining and have us service their batteries every 18 months, who are frequently getting 11 to 14 years service out of their batteries!!!
