i have a first generation 5gig ipod, and have changed the battery once myself a year ago with a new aftermarket battery because the battery life had decreased to about six hours, (remember the days of the eleven hour ipod?) ... i ride a motorcycle with a magnetic tankbag, strong magnetic bottom panel holds it in place on the steel gastank. in the past i've been careful about the proximity of this to my ipod, but one day i just forgot. after that one day, the battery just quit. it never, ever, holds a charge. and when it does, it does so for about three minutes of play. did the magnets destroy the battery? the ipod works fine when plugged in... did this battery just quit? i wasn't aware that magnets could effect lithium ion batteries... thanks... r.
