If you don't ever use the battery, maybe run that flat and then just take it out and run it out of mains. You take away the batterys life cycle if you leave it full and it doesn't get used.

Lithium Ion battery life facts -

Most lithium-ion batteries have a discharge/recharge cycle life of between 300 and 500 times. In practice this is a life of about 2 to 3 years. Lithium will last longer if its not fully discharged i.e. topping up is actually better for their life and chargers are designed to stop charging when full. Smaller batteries (like those in iPods or cameras) which are frequently discharged/exhausted will not last as long.

Lithium batteries also have a shelf life – if left unused they will deteriorate in 2 to 3 years.

Lithium batteries deteriorate far more quickly in hotter climates as well – for example after 1 year at 25 degrees they will lose up to 20% of their charge capacity, at 40 degrees up to 35% and at 60 degrees they will lose 40% after only three months. And this repeats for future years.

Lithium batteries should never be opened, put in water, or disposed in the the domestic waste stream. Lithium bateries can usually be repacked by specialist battery repackers.

Some very useful information there. Basically, in your situation you'll want to remove the battery, and store it in a cool dry place with about 40% charge.
