Hi David, What about leaving an iPad plug in for long periods. I use my iPad almost every day and night for long periods and I have left it plug in for long periods of time. What is your opinion on this.

This pack has different charging and power rules than the older Ni-Cad or Ni-MH battery packs. First, you only need to initially charge the pack to full. There is no need for an initial 24 hour charge cycle. Next, only run the battery pack through a complete charge cycle once per month, and this is actually done to reset the battery charge monitoring circuitry. Third, Li-Polymer battery packs prefer shallow charges. The best to use, if one is always by power, is 30% to 80%. However, this is not practical for most people, so iOS circuitry automatically switches to trickle-charge when the battery pack exceeds 90%. Also, 100% is displayed when the battery pack is actually around 98 to 99%. This is to encourage people not to over charge the battery pack. Fourth, when one gets the low battery warning, it is best for the battery to plug the iOS device in and start charging as soon as possible. If the battery pack is run down too low, this can shorten the life of the battery pack. On the iPhone and iPod, this is 20%. On the iPad and MacBook, this is 10%. In the case of the battery packs, Apple knows more than the end-user. Li-Polymer batteries are different from the older battery types, so what you used to know about rechargeable battery packs has changed. Oh, and Li-Polymer battery packs do not contain toxic materials like the older rechargeable batteries, but they are a little more combustable.
