I am using my CBAII to do some D cell battery tests to work out which make of D cell battery would give the best run time in a genuine 2D cell Rebel 90 Maglite.
With fresh batteries the light draws 1.6+A which start dropping as soon as the light is turned on and stabilises to around 1.6A even. What kind of circuitry do the Magleds use? Boost only or boost and regulate constant current for as long as the battery allows? What is the lowest battery voltage that the boost circuit will continue to operate at 0.9, 0.8V per cell??
Setting the CBA to a constant 1.6A naturally one only gets a run time of about 50 minutes or so down to 1.1v. Clearly this does not simulate the current draw of the Maglite. However could one still draw the conclusion that whichever brand of D cell lasted longer at a constant 1.6A would also last longer if used in the Maglite? Should I rather run the tests at whatever the average current draw would be say 750mA? This would allow those batteries that perform better at lower currents to out perform those that work better at higher currents.
Any advice would be appreciated.
