Like other rechargeable batteries, these batteries may eventually require replacement
像其他可充电电池一样，这种电池最终也将被替代。
Standard Technology 基本技术
Lithium-ion batteries pack in a higher power density than Nickel-based batteries. This gives you a longer battery life in a lighter package, as Lithium is the lightest metal.
You can also recharge a Lithium-ion battery whenever convenient, without the full charge or discharge cycle necessary to keep Nickel-based batteries at peak performance. (Over time, crystals build up in Nickel-based batteries and prevent you from charging them completely, necessitating an inconvenient full discharge.)
锂离子电池储电密度要比镍电池大。这样更轻的电池块也可以得到更大的电量，因为锂是最轻的金属。你可以在任何方便的时候对锂离子电池进行充电，而不必像镍电池那样，为了保持最高性能而进行完全的充放电。（随时间的增长，结晶体会堆积堵塞镍电池，妨碍你对电 池完全充电，进而迫使完全放电也很困难。）
Standard Charging 标准充电过程
Most Lithium-ion batteries use a fast charge to charge your device to 80% battery capacity, then switch to trickle charging. That’s about one hour charge time to power iPod to 80% capacity, then another 2 to 3 hours to fully charge iPod, if you are not using iPod while charging. You can charge all Lithium-ion batteries a large but finite number of times, as defined by charge cycle.
大多数锂离子电池可以快速充满所用设备80%的电量，然后将转变为涓流充电。充满 iPod 80% 的电量大约要1个小时，而要完全充满 iPod 则还需要2到3个小时，这是在充电时不使用 iPod 的情况下。所有的锂离子电池都可以进行很多次充电，但这个次数是有限的，它是由充电循环决定的。
A charge cycle means using all the battery’s power, but that doesn’t necessarily mean a single charge. For instance, you could listen to your iPod for a few hours one day, using half its power, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two, so you may take several days to complete a cycle. Each time you complete a charge cycle, it diminishes battery capacity slightly, but you can put both notebook and iPod batteries through many charge cycles before they will only hold 80% of original battery capacity. As with other rechargeable batteries, you may eventually need to replace your battery
一个充电循环就是用完所有的电池电量，而不是单一的一次充电。比如说，你可能在一天里听iPod几个小时，用掉了一半电量，然后再充满。如果你明天仍然是这样做，那就记作一个充电循环，而不是两次，所以说，用完一个充电循环可能要花几天的时间。每用完一个 充电循环，就将减少一点点电池容量，但是要使笔记本和iPod的电量降到原始电量的80%要经受很多充电循环。和其他可充电电池一样，最后就必须更换电池了。
How to Maximize Power Use 怎样使用最佳
The length of time your battery will power your device depends on how you use it. For instance, watching a DVD will use up your notebook battery’s power more quickly than simple word processing. You can follow some simple steps to maximize your notebook’s or iPod’s battery life。
电池的续航时间在于你的使用方法。比如说，看一部DVD就要比文字处理耗费更大电量。遵循一些简单的步骤就可以使你的笔记本或iPod的电池寿命达到最大限度。
Standard Maintenance 日常保养
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all time. An ideal use would be a commuter who uses her iBook on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month。
要正确的保养锂离子电池，最重要的是要保持电池中的电子间断性的活动。Apple 建议你不要让本本一直插着电源。最理想的使用方式是，就像经常来往于两地的人，在火车上用iBook，而在办公室用电源充电。这样能保持电池液的流动。如果是另一个方式，工作时用台式机，本本只是偶尔出差时用，那么Apple 建议你一个月至少充放电一次。
Long Term Storage 长期保存
If you don’t plan on using your portable for a length of time, for example, if you manage an iBook lab at a school that’s not in session over the summer, Apple recommends that you remove and store the battery with a 50% charge. If you store a battery when it’s fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged, the battery may experience some loss of battery capacity, meaning it will have a shorter life. Eject the battery from your PowerBook or iBook and store it at the proper temperature.
如果你有很长是时间不打算用本本，比如说，你在学校管理着一个iBook实验室，而学校夏天又不上课。Apple 建议你把电池卸下来，充入50%的电量存放。如果你在电池完全放完电的时候存放，电池将进入深度放电状态，这将造成电池不能再充电。相反的，如果你充满电存放，电池就将损失一些容量，也就是说电池寿命会缩短。从PowerBook或iBook上卸下电池并 在合适的温度下存放。
Calibrating your computer’s battery for best performance
校准电池以得到最好的性能
The battery has an internal microprocessor that provides an estimate of the amount of energy in the battery as it charges and discharges. The battery needs to be recalibrated from time to time to keep the onscreen battery time and percent display accurate. You should perform this procedure when you first use your computer and then every few months thereafter.
1．Plug the power adapter in and fully charge your computer’s battery until the battery indicator lights turn off and the adapter plug ring goes from amber to green, which indicates that the battery is fully charged.
2．Disconnect the power adapter and use your iBook or PowerBook. When your battery gets low, you will see the low battery warning dialog on the screen. Continue to use your computer until it goes to sleep. At that point the battery has been sufficiently drained for calibration.
3．Connect the power adapter and leave it connected until the battery is fully charged again.
You have to fully charge and then discharge your battery only once to calibrate it. After that you can connect and disconnect the power adapter when the battery is at any charge level.
TIP: When the battery reaches “empty”, the computer is forced into sleep mode. The battery actually keeps back a reserve beyond “empty”, to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. At this point, any open files could be lost. Therefore, it is important that you find an electrical outlet and connect the adapter before the forced shutdown occurs.
电池有一个内置微处理器，它通过电池充放电的过程来提供电池内电量的估计值。要时常对电池进行再校准以保证显示器所显示的电池时间和百分比的精确性。在你第一次使用本本和此后的每几个月，你可以进行以下操作：
1。接上电源适配器将电池充满，直到电池指示灯熄灭和电源适配器plug ring（不知道这个是怎么翻译） 从黄色变为绿色，显示电池充满电。
2。断开电源适配器，然后使用iBook或PowerBook。当电池低电时，你将在屏幕上看到低电警告窗口。继续使用本本，直到休眠。这时电池就已经充分耗尽到校准点。
3。接上电源适配器，再次将电池充满电。
你只能完全充放电一次来校正电池。在此之后，你就可以随时连接或断开电源了，无论电池的电量如何。
提示：当电池电量为“空”时，本本将被迫进入休眠状态。而电池实际上是保持了一定电量而非真“空”，这样是为了维持本本能休眠一定的时间。一旦电池真的耗尽了，本本就不得不关机了。在这时，所有打开的文件都将丢失。所以，找个插座在关机之前接上电源适配器 还是很重要的 |
