“To help revive iPods with power cells that can no longer hold a charge, Newer Technology and Other World Computing have entered the iPod-parts business, introducing a high-capacity lithium-ion cell that can last longer than the iPod’s original battery. The high-capacity 2100mAh iPod replacement battery has a capacity 70 percent greater than the original, which the company says will add hours to the iPod’s original 10 hours of playing time between charges. At $40, it is a smaller drain on the wallet than replacing an old iPod with even the least expensive new one.”
