iPodJuice has added battery replacement kits for fifth-generation iPods. The company is offering a 550 mAh battery ($24) for 30GB iPod models and an 850 mAh battery ($28) for 60GB and 80GB models. iPodJuice also offers the batteries in complete replacement kits—with an iOpener installation tool, mini screwdriver, and detailed color instructions—for $5 more. You can also send your iPod into iPodJuice to have their technicians perform the battery replacement for as little as $20. In most cases, batteries are replaced the same day that they are received and shipped back to the customer on the following business day, according to the company.
