Which resistor to build 6V photo lithium tester?

Hello, and Happy New Year to everybody.

My battery tester uses a (too weak) 10mA load for its 6V test.

I'm guessing that a 2CR5 Photo Lithium battery should be tested at
150mA, under load.

Any electronics geniuses out there? What type/size resistor should I
connect to the battery, while testing with my battery meter, to
simulate a Canon SLR's load, and provide me with an estimation of the
usability of my 2CR5 (and other 6V lithium) batteries?
I also have a DMM.

Thanks for all advise and tips.

Ohm's Law:
R = V/I = 6V / 150mA = 40 ohms.
Nearest preferred value = 39

Power dissipation P = V*I = 6 * .15 = 0.9 watts

Try a 39 ohm, 1 watt resistor.
