  • The battery can be pried out of the case with an iPod Nano opening tool, but unfortunately, it is soldered to the logic board.

  • The 3.7 V lithium-ion battery has a listed capacity of .39 Watt-hours that provides up to 24 hours of continuous music playback.

  • Converting to the usual amp-hours, we see that the Nano's battery has a capacity of 105 mAh, compared to the Shuffle's 51 mAh.

  • This iPod Nano's battery only has two wires, one red and one black. All the other iPod Nanos we've taken apart have included three battery wires. That third battery wire typically ties into a thermistor, a resistor whose value changes with temperature (a poor man's thermometer). Presumably the iPod Nano's battery is small enough and the charge rate is slow enough that overheating is not a concern.

电池可以使用iPod Nano打开工具脱离外壳,但不幸的是,它被焊接到逻辑板上了。

3.7 V锂离子电池的标称容量为0.39瓦时,可提供长达24小时的连续音乐播放。

转换到通常的安培小时(mAh),与Shuffle的51 mAh相比,Nano的电池容量为105 mAh。

这款iPod Nano的电池只有两根电线,一根红色和一根黑色。 我们拆解的所有其他iPod Nano都包含三条电池线。 该第三电池线通常与热敏电阻连接,其值随温度变化的电阻(可怜的人体温计)。 推测新iPod Nano的电池足够小,充电速度足够慢,因此过热不是问题。
