Anyone Here Good At Maths and Electronics?

Hi Guys,

What I want to know is - is there a way of working out how long a battery will last at certain power consumption?

What I'm looking at are Bluetooth devices and I want to know if they are battery powered how long the battery will last before it needs to be recharged?

I found this website and I know my typical rechargable AAA battery says 550mah on the side and 1.2 Volts

Any ideas how to work it out? Without actually building a device and testing.
