Searching google is often more effective, if you know the right incantation to make it only search iTT. While "battery" on the site search brought up 52 hits, "battery drain" brought back 1 and it's specifically related to the 800 not charging issue. Unfortunately google can also provide a lot of useless hits as well. I hate to say it, but it's not always obvious even for a well trained person to find the appropriate information inside iTT threads.
