Actually that shouldn't be a problem. Just don't leave it discharged for long periods, and avoid draining it deeply if possible.
It's actually a good idea to wear down the battery pretty far (15% or so, until you get the warning) from time to time, then charge it up completely. Every month or two should be good.
Lithium batteries can be thought of kinda like muscles - they need some exercise to stay strong, although they do not suffer 'memory' like nickel based batteries. They will also atrophy if they are left discharged too long.
