Here’s an interesting deal for the brave do-it-yourselfer looking to replace their iPhone battery. For only $7.29 (shipping is free) you can replace your own iPhone battery.

　　This is cheaper than the $85.95 that Apple charges. Of course this completely voids your iPhone warranty, and the repair process is not for the faint of heart. If you’re still interested, jump on over to the next page where I’ve got both the link and iPhone battery replacement video.
