iPad 1st Vs iPad 2nd Battery

In few last minutes I got message in my yahoo mail inbox. The message in coming from Apple. the Message is about the different performance of the Battery life varies by use and configuration between iPad 1 and iPad 2. And in that massage he sayed, iPad 2 is currently unavailable in Indonesia. To keep informed about iPad 2 availability, please click here.

Lithium-ion Battery

Rechargeable lithium-based technology currently provides the best performance for your Apple notebook computer, iPod, or iPhone and iPad. You can also find this standard battery technology in many other devices. Apple batteries share the characteristics common to lithium-based technology in other devices. Like other rechargeable batteries, these batteries may eventually require replacement.

Standard Technology

Lithium-ion polymer 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 polymer 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.) 

Standard Charging

Most lithium-ion polymer batteries use a fast charge to charge your device to 80% battery capacity, then switch to trickle charging. That’s about two hours of charge time to power an iPod to 80% capacity, then another two hours to fully charge it, if you are not using the iPod while charging. You can charge all lithium-ion batteries a large but finite number of times, as defined by charge cycle. 

Charge Cycle. Using and recharging 100% of battery capacity equals one full charge cycle.
A charge cycle means using all of 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 notebook, iPod, and iPhone 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.

How to Maximise Power Use

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 easy steps to maximise your notebook, iPod or iPhone battery life.
If you use your iPod, iPhone, or notebook in temperatures higher than 35° C (or 95° F), you may permanently damage your battery’s capacity. That is, your battery won’t power your device as long on any given charge. You may damage it even more if you charge the device in these temperatures. Even storing a battery in a hot environment can damage it irreversibly.
