Sonnet is all about making your Apple-based product better. Whether it's swapping out the CPU for a new one or adding Firewire support, they've got something. So Sonnet has just released high-capacity batteries for your old iPod. From the first to the fourth generation and the mini, you all can now enjoy longer battery life and improved performance. How much longer you ask? Try 78% longer with over 20 hours of playback on a single charge. Dude, you're totally set. They won't even break the bank. First and second gen iPod batteries cost $40, but all the others are only $30 and come with installation instructions so you can do it yourself. Available in November, this would make a great stocking stuffer for someone who has a crappy iPod.
