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.

The user-replaceable battery is a standard CR2032 lithium coin battery available almost anywhere batteries are sold.

Beta and Gamma Radiation: "...cesium-137 is of particular concern because it is a potential component of a conventional explosive device (a "dirty bomb") containing radioactive material." - FDA "Dirty Bomb" treatment document Beta Radiation: "..

No, the RadDetect radiation detector cannot be turned off unless you remove the battery. The RadDetect was designed to virtually eliminate any possible human error. If the user approaches a dangerous radioactive isotope, the RadDetect will instantly sound an alarm.

We expect about one or two years of usage with about a charge per day average. 400 to 600 cycles are realistic. Battery degradation is a gradual thing.

detection levels - Beeping and flashing of the auto-alert occurs at 256 varying rates of speed (similar to a Geiger counter or metal detector). This level of instant preciseness makes the directional feature very easy to use. Watch Demo video #1. PLUS - Pressing the gray diagnostic button allows for additional instant analysis of exposure level (low - mid - high). See question #26 for more info on the gray diagnostic button.

We do not guarantee the amount of charge held by a battery in any way at all on anything but our "Refurbished as New" machines. On these machines the battery will last for at least 1 hour of regular computing which does not use the DVD or CD drive.

A fully charged battery will last up to 10 hours. The rechargeable battery is included and will last a long time - usually 1 -2 years. You can buy a new battery by ordering directly from our site, calling us toll free at 1-888-883-3277 or by visiting an authorized TV Ears retailer.

It will take approximately 7 to 9 business days for your replacement battery to arrive. Shipping time may vary due to availability of your battery model.

Direct Conversion - When a radioactive photon strikes a depletion region created by reverse bias on the photodiode, it produces a small amount of charge in proportion to the photon's energy. The resulting signal is then amplified and processed by the CPU in the RadDetect?.

Yes, it is safe. The RadDetect is tuned to ignore, and cannot be damaged by, artificial radioactive sources like package canners and x-ray equipment used by airport security. It can be used around and near scanning equipment without the hassles of false alarms, and without interfering with the scanning equipment.

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.

Using the VBC Vagabond Battery Charger, it will take about five hours to fully recharge an exhausted battery. This is typical of all lead-acid battery systems when charged at the recommended rate. If the battery is not completely exhausted, the recharge cycle will take less time.
