A week ago i read in a website saying that the battery of an ipod only last 18 months. The battery is not self replaceable, and before... Apple do not take the service of changing the battery. An advice of buying a new ipod was offered instead. It makes me shiver. Now apple has changed its policy and accept battery-replacing service for $99, which had not calm me down. So i look up for a good reliable information about maintaining battery life, which i found in http://www.batteryuniversity.com/ please check and find out if you like.
I'll give a summary for those who don't really want to spend their time reading all about batteries. But it will only about lithium battery, because nowadays.. almost all electronic gadgets are stuffed with lithium batteries.
じゃ、始めましょう。
1.Never let lithium battery become completely empty.
2.It is okay to charge the battery overnight. (There is no term as overcharged in lithium batteries)
3.Yet it is not neccesary to charge it for 8 hours the first time you use the battery.
4.Lithium battery accepts partial charge.
5.The term "300 cycle charges" does not carry the meaning of "how many times you plug the battery to the charger." So, you may plug your battery often.
6. Avoid lithium battery from heat. (this is mostly the problem of a laptop)
7. Battery is best if used at least every 1 week.
8. If you are not going to use the battery for a long time (10 days), never store it in 100% full capacity. Instead 40% capacity is advised.
That is what i learned, go check for your self to be sure. at http://www.batteryuniversity.com/
