Reset your iPod: To reset your iPod, toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.) Next, press and hold the Play/Pause and Menu buttons until the Apple/iPod logo appears, for about six to ten seconds. You may need to repeat this step. For more information on resetting your iPod, please visit http://docs.info.apple.com/article.html?artnum=61705/.

Answer: The easiest way is to connect it to the Apple iPod Power Adapter. You can also charge it by connecting iPod to your computer or putting it in its optional dock. For additional information, see "Charging iPod's internal battery" Answer: You don't need to empty the battery before charging it. Lithium-based batteries, like those used in iPod, have none of the memory effects seen in nickel-based rechargeable batteries.

There are six simple steps in testing a deep cycle battery: inspect, recharge, remove surface charge, measure the state-of-charge, load test, and recharge. If you have a non-sealed battery, it is highly recommended that you use a good quality temperature compensated hydrometer; these can be purchased at an auto parts store for between $5 and $20. A hydrometer is a float type device used to determine the state-of-charge by measuring the specific gravity of the electrolyte in each cell.

Answer: iPod and iPod mini have built-in, rechargeable lithium-ion batteries. For more information about this battery technology, see the Apple Batteries website.

Answer: The standby time is 1 month when fully charged. After a month of not being used, the battery will likely be fully discharged. You may find that the battery is empty before then, and that's normal. Even when it's not being used, iPod uses a small amount of battery power. Lithium-ion batteries need to be used for maximum performance. If you don't use your device often, be sure to complete a charge cycle at least once per month.

Answer: You can perform a simple test to tell if your battery is working properly. Follow the steps in "iPod's battery indicator is approximate".

Answer: See "Tips and tricks to get the most out of your iPod's battery" for information on how to extend your battery life. Answer: Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. Battery life and number of charge cycles vary by use and settings. As with other rechargeable batteries, you may eventually need to replace your battery.

The Spatial Test Battery assesses student ability in the area of spatial reasoning. This is a computerized test, given at a Prometric test center. The test consists of three parts for 5th & 6th graders, four parts for 7th & 8th graders, and the entire test is usually completed within 90 minutes, sometimes as little as 30 minutes. This test is open to students in grades 5 through 8.

Reporting multiple failures in a single test is generally a sign that the test does too much, compared to what a unit test ought to do. Usually this means either that the test is really a functional/acceptance/customer test or, if it is a unit test, then it is too big a unit test. JUnit is designed to work best with a number of small tests. It executes each test within a separate instance of the test class. It reports failure on each test.

Answer: The battery indicator is only an approximation of the amount of power that's left. For more information, see "iPod's battery indicator is approximate".

Yes. Apple has an official battery replacement program for $59. The program requires that you send in your iPod (any model), and Apple will replace the battery and return it to you for $59 plus shipping and handling (technically, Apple actually replaces your whole iPod with an equivalent new or refurbished model). AppleCare programs for iPod are also available in some markets outside the US, and are expected soon in other markets.

Yes. Over time, the battery will not hold the same amount of charge as when it was new. This is natural, and is true of all lithium ion batteries. This slow degradation will not affect, or be noticed by, most users. However, based on usage, environmental factors, and many other variables, some heavy users may notice a greater degradation than others.

Apple's specifications specify a battery life of 10 hours for the 1st and 2nd generation iPod, 8 hours for the 3rd generation iPod and 1st generation iPod mini, 12 hours for the 4th and 5th generation iPod and iPod shuffle, 15 hours for iPod photo, and 18 hours for the 2nd generation iPod mini. Many factors can, of course, influence this. Under good conditions, you should indeed get around the specified hours of battery life on a new iPod.

A dead battery would result in a "BD" grading from our testing department, and your iPod would be disqualified.

To charge your iPod's battery completely takes approximately 3 hours. In general to charge 80% it takes just one hour.

Yes! We have a whole slew of them. Watch one of our technicians replace an iPod battery using one of our kits.

Yes! Although our battery replacement instructions are very detailed, we realize that some people just don't feel comfortable cracking open their iPod and messing with circuit boards and power connectors. ipodjuice.com offers several options depending on your level of urgency.

The Apple Support Site provides "Tips and tricks to get the most out of your iPod's battery". This document offers some useful information including updating to the latest version of the iPod software, setting the Hold switch to the Hold position when the iPod is not in use, and keeping the iPod at room temperature, among others. Generally, keeping the iPod from becoming completely discharged also may prolong the life of the battery. BatteryUniversity.

Positive grid corrosion. This is a natural occurrence over time, however it is accelerated by operating in an extremely hot climate or by overcharging. Overcharging can occur due to malfunction on the part of your vehicle's electrical system. Vibration is also a major reason for battery failure.

There are several external factors that contribute to battery failure. Excessive heat causes the positive plate to quickly corrode and this dries out the battery cells. This is probably the number 1 reason for failure. Extreme Cold weather makes your engine harder to crank because the oil thickens in your car and this puts a heavier drain the battery. This also is a contributor to failure.

If the iPod is out of warranty, Apple will replace the battery in your iPod or iPod shuffle for US$59. A variety of third-party services are also available. Often, companies other than Apple will provide batteries with greater capacity (runtime) at a lower price and are well worth consideration. It is not particularly easy, and potentially not even cost-effective, to replace the battery in the iPod nano or iPod shuffle models, as the battery has leads soldered to the logic board.

Results from the Spatial Test Battery give students and families an understanding of a child's visual-spatial abilities. CTY's test is one of the only exams of its type conveniently available for students this age. This assessment may bring a previously unrecognized strength to light. Special talent in this area can be of great benefit for the later pursuit of mathematics, natural sciences, engineering, architecture, and other fields.

Yes, after the problem has been corrected our sampling technicians will come back to collect a post-treatment well water test sample.

A test case should consist of pairs of action and verification. It is possible to omit verification, if the next action depends on result of previous action. Actually, verification in that case is hidden because we are waiting for some object to make next action on it. If specified time expires, waiting fails and some JemmyException (extends RuntimeException) is thrown. This exception can be caught in our test case or it is propagated to a test harness in which the test case runs.

The short answer is yes. The slightly longer answer is that it depends on how comfortable you are with opening electronic devices, fiddling with wires, and moving around tiny components. For the most recent iPod models, changing the battery is not rocket science, but it's not as simple as, say, adding memory to a computer. Even some of my tech-savvy friends were a bit worried when changing batteries in their iPods. (As for me, I've never done it yet...) Before you leap, why not look.

You bet! Plus, we'll even give you a super-special discount on the battery replacement, since we're already working on your iPod. Just ask your iResQ Technician for this special when contacted about your repair.

Warning: When running restore, be sure to do a backup of all your songs. When you do a restore you are erasing all of the songs currently on your iPod.
