I am a lithium battery scientist and today I talked to my battery manufacturer colleague, he told me the true cost of the 5800 mAh is by no means to be more than $30. The standard one comes with HMC150 is 2500 mAh at 7.2V, it is composed of 2 pouch cells rated at 2500 mAh. The 5400 mAh is composed of 2 pouch cells rated at 5400 mAh. Since the pouch cell is standardized at Panasonic, it is very cheap to make them. Then Panasonic will modify the case and connector each time a new camera comes out to rid off copycat. A profit margin about 400-500%.
When Panasonic sells the laptop battery (bigger than camera battery) to Dell or Apple, if it costs them $31.00, they will NOT get more than $31.99 from Dell or Apple, so the profit is about 3-5%.
Now you should also understand why Panasonic charge so much for their P2 cards or SDHC.
