@aanuszek1 .. batteries don’t work like that anymore, esp. lithium ion batteries, they don’t have any memory at all, they just have a certain amount of life period, fully charging and discharging it (FYI discharging ANY battery completely is VERY VERY bad for it).
any new rechargeable electronics these days if you plan on storing them, store them with about 30% battery life (give or take 10%), otherwise it can damage the battery.
Like I was saying though, liion batteries only have a certain life expectancy, say like 300,000 hours or something like that, depending on what it is it can range up way further than that, and of course so many recharge cycles.
So whatever you do, discharging and recharging your ipod or any devices within the past like 4 years will only wear them out even further.
Call apple, because the last guy that tried to replace ipod batteries .. let’s just say got into a little bit of trouble, as far as a lawsuit on replacing batteries can go, in other words.. only apple is “allowed” to do it really.
