For 40 bucks you can buy some fairly sexy items for your IPod--a cool case, some hip headphones, or a sleek stand--but I've yet to find a $40 accessory that adds as much value to a first- or second-generation IPod as Newer Technology's high-capacity IPod Replacement Battery. Sexy it ain't, but there's nothing unattractive about the battery's ability to power an IPod uninterrupted for over 21 hours.
What You Get
Newer Tech's Replacement Battery comes with printed instructions that detail how to open the IPod and replace the original battery, as well as two nylon tools for opening the case. I tested the battery on my Frankenpod--an original first-generation 5GB IPod that carries a 15GB drive I salvaged from a third-generation IPod. This IPod has been opened enough times that I'm now able to remove the backplate with my fingernails. So, to test the tools, I used them on a 20GB second-generation IPod that I've never opened.
