I'm building a light meter and I don't have much room for a battery. I can fit a 2450 lithium button cell, I don't know if a 2450 primary lithium button cell will supply enough current. I will probably need to draw 20-40ma at 5V (~150mW) to run my lightmeter. I have a 5V boost driver so I can use voltages down to 1V. Can a 2450 primary cell drive this much current? The datasheet I found for the energizer 2450 lithium cell specs are all quoted at 0.39mA! I might need 2 orders of magnitude more than that.
