If you find that you're regularly pushing the limits of your iPod's playing time, you might consider putting in a higher-capacity battery, even if yours isn't worn out yet. For about $30, iPod upgraders such as iPodResQ, Other World Computing, and TechRestore will sell you batteries with a higher milliamp-hour rating than the stock Apple battery, as long as you have the guts to install a new battery yourself (see Newer Technology's iPod-disassembly instructions at www.newertech.com/support for help). If you're not up to that task, have no fear - the same companies will put the battery in your iPod for a few dollars more.”
