I drained the battery on my N3DS

Does the battery meter not work? Thought it the battery was still full. I was just thinking how long does it last. The red light was on too. Not sure how many hours I played total. I have a USB cable and a USB battery. I should buy a new USB battery, the newer model is smaller but it might have higher capacity.

The new model has a slightly higher capacity. It might be longer then the one I have.
