If the mighty iPod has an Achilles heel it just may be its internal battery. From the class action suit to the legions of third party replacement batteries (as well as Apple's own recycling program), it's that one issue that just won't go away. Today Newer Technology got involved by offering a replacement battery of their own.
Theirs is a high-capacity 900mAh battery, which Newer claims will provide 28 percent more run-time capacity for iPod photo models and 50 percent more run-time capacity for the fourth-generation 40GB iPod (the battery is intended for all iPod Photo models and fourth-generation 40GB iPod models). Though it comes with instructions and installation tools, the folks at Newer suggest you let a pro hande that job. It will run you $29.99US.
