I found my old click wheel iPod in the cupboard and decided to replace the original battery with the iFixit one, it was not holding a charge as it's around 15 years old.
iFixit battery does not hold a charge suspect something is severely draining it.
Have charged the device all day and came home the display looks to still be charging.
Unplugged FireWire charger and the unit shows the no battery icon.
Does anyone know if battery drain can be fixed?
