ThanksNot sure by what you mean by "mains" but if you have it plugged in to ac all the time if I'm understanding you correctly, then yes, to removing the battery..
This is how I use my laptop 98% of the time.
Will doFirst run the battery down to a low level before removing it but don't completely deplete it, leave it at about 30- 40%.

Thanks Griz, you've dispelled the myth!..Not from the main battery. The only thing that is powered while the computer is off is the CMOS which is fed either with a large capacitor or a 3V Button cell battery. Even if the main battery supports the off state, the current is so low that is negligible ... its like a 100gal water tank looses a drop of water every day.
Maybe I'm old school but I believe laptop batteries et al survive best if they're occasionally worked hard ie fully charge them then run them down, under load, to 20-30%. I'd do that every 6 months.
Thanks Norton.Laptop batteries can't take the heat, that's why your owners manual says charge to 60% and store in a cool dry place until required. I'm a firm believer of that after being in industrial electrical maintenance field for 46 years.
This should clear up the grey areas re-batteries.

FYI Whilst on the battery topic:
I just dumped AVG antivirus off my android phone and downloaded Avira Portable.
I love it, and it also has battery overcharge protection. Most cell phone fires are caused by overheated (charging) batteries.
