FastMac has expanded its TruePower line of replacement iPod batteries with the addition of a battery upgrade for all fourth-generation iPods. The company is accepting pre-orders now for the $29.95 battery, which will ship next month with a 2-year warranty and necessary tools and installation instructions.
“TruePower upgrades replace the iPod’s original internal Lithium-Ion battery with a larger capacity and longer lasting advanced power cell,” explains FastMac. “The upgrade offers 20%-70% more capacity than the original (depending on iPod model) and up to 7.5 times as many charge cycles. This is accomplished through the use of TruePower’s patented nanoparticle technology, which significantly slows the degradation of the battery.”
