iPod 3G battery replacement

Apple iPod (3G) third generation 15Gb. My first iPod back in 2003 to work with windows... firewire only. Back then, windows PC dont come with firewire port. Have to get a firewire port PCI card...and iTunes for windows 98. This is the best iPod by far, with no movable control buttons, cept for hold switch. Thinking it couldlast for years...and it did!

2009, battery last less than 20mins and on permanent charging in the office. Time to change the battery. Bought one from dealexteme.com at low low price of USD5.84. Then comes the problem, the iPod is a tough nut to crack. Broke the 2 plastic tool and left it on the desk until in feb, while clearing the desk, decided to try again with penknife and managed to replace the batt ... finally. on the 7th year. A new life.
