Not coming from the battery. My one macbook did that. It was one that work owned and came to me used. Never did warn me when to shutdown. Somewhere between 5-20% life left on the battery, the thing would just shutdown hard. The tech at work never could figure it out and I just lived with it. Not sure if it was something in the computer, or something wrong with the monitoring circuitry of the battery. You could always try resetting the PMU. Google 'macbook pmu' or 'macbook smc'. It might help but probably not.
