If the battery can "burn itself out" without causing any problems... why bother to install the battery in the plane at all?

This has a good explanation of what the main battery is used for: http://787updates.newairplane.com/787-Electrical-Systems/Batteries-and-Advanced-AirplanesIf the battery can "burn itself out" without causing any problems... why bother to install the battery in the plane at all?

In normal operation with engines turning the batteries are not used for much. They are used on the ground when the engines are off, and the aircraft is neither connected to shore power nor is the APU on, and also in case of loss of engine power in the air, in that very unlikely event. Naturally in the normal course of operation the batteries are not supposed to burn. But should they burn in an unlikely event, it is important to keep such from compromising the rest of the aircraft. And that is what was achieved in the redesign of the battery container.
How did they make their determination? Did they run a test battery of battery tests?

They ran battery of battery tests on test batteries?
Well actually the thing being tested was the stainless steel container more than the burning battery I suppose. We already knew that the batteries catch fire an burn. The questions was will the battery container contain said fire adequately? The previous ones did not, the new ones did and successfully vented all the foul gases to the outside.
