It does not harm or reduce battery life to leave the battery installed while on AC power. I'm assuming that you use the computer on battery power regularly are not storing the battery long term.
I only have ONE QUESTION remaining, about Point 2 :Assuming the surge in AC supply is 100% reliable, Is it a good idea FOR THE BATTERY LIFE, to remove it when you work with AC supply ?? There was no conclusion on this debate between your post and the comments.

What really drains the battery in Vista is Windows Aero. Disable it and get more than half an hour of additional battery life for free.
Also disable that stupid superfetch service that re-caches your most used files into RAM whenever you boot or resume from disk. You should disable scheduled defrag as well (it is enabled WEEKLY by default, what a nonsense).
Lenovo has a HUGE bug when it comes to USB. Whenever you enable USB (Internal Bluetooth or WWAN use USB as well!),your X300 drains a LOT more power and gets hot. Disable both and don' t use any USB devices while on battery to get a long runtime.

Thanks for the USB tip. What is the easiest way to enable/disable USB?
Also, I need to buy a new 6 cell battery and I am having a devil of a time of it. I can't seem to buy one from the French Lenovo website. And their recommended vendors don't have this battery and/or don't accept Amex. Nor do they respond to emails. The UK website has good prices, but can't seem to handle my French Visa credit card, and they don't accept Amex. Should it be so difficult to buy a battery from Lenovo?
