Just wondering whether you can take out the battery while using mains power to preserve it? is there any point-i would have thought there was an automatic cut off of power to the battery when charged

If you're not going to use your battery for a while, charge it to 50% and remove it. Run it through at least one charge/discharge cycle every month.

But be advised that Apple has designed the Intel Macs to fall into a low-performance state (clockrate goes to 1Ghz) when the battery is removed.
