Lithium-ion (Li-ion) Batteries
November 3rd, 2009
Lithium-ion batteries are the newest technology batteries and offer several advantages over NiMH and NiCd batteries. Lithium-ion batteries are preferred for their lighter weight and higher performance. Lithium-ion batteries are typically 20-35% lighter and will provide 10-20% better performance than a NiMH battery of equivalent mAh rating.
Lithium-ion batteries are also unique in that they are not susceptible to the “memory effect”. A new Lithium-ion battery will benefit from an initial “conditioning” of the battery. For the first 3 charge cycles, fully charge the battery overnight before recharging. Once conditioned, Lithium-ion batteries will perform best when charged at a rate somewhere between a conventional slow charge and a rapid charge. When rapid charging, Lithium-ion batteries require a charger designed to charge Lithium batteries.
To achieve a true full charge when rapid charging, the battery needs to be slow charged the last 10-15% of its charge cycle. Most “intelligent” desktop and Lithium-battery rapid chargers provide this capability. A Lithium-ion battery may be damaged by extensive overcharging (continuously on a charger for more than 24 hours).

Google Docs Backup
If you use Google services like Gmail, Calendar, Docs and Spreadsheets, Reader, or Blogger, you’ve got a life’s worth of data on Google’s servers. Unless you back up your stuff locally, Google holds the keys to your digital life and you’re out of luck if and when Google loses or denies you access to that data. Rather than run screaming for the hills, a few steps to back up your Google-hosted data can ensure that you’re in control of your stuff.
Download and back up your Google Docs and Spreadsheets
If you word with online word processing and spreadsheets bandwagon, you’ve probably already got a lot of docs on Google’s servers. By default, backing up those files means you’d need to download them one at a time, which is quite frankly a tedious waste of time. Instead, this tools can back up all or select chunks of Google Docs and Spreadsheet files in various formats (including MS Office or Open Office formats, PDF, plain text, or CSV) in one fell swoop using the Google Docs Backup. This solution requires a little diligence on your part, you’ll need to regularly back up the docs yourself, but the Google Docs Backup makes the process fairly painless.
