I have three 50mW lasers twom from DX and one from o-like. All threec are powered by 2 AAA batteries. When I try alkalines all three work fine.
When I try NiMH it is dependant on the type: fully charged it works best but one DX is still rather dim.
I measured the current : the alkalines (open circuit voltage 1.51 V per battery) draw over 200mA (as expected) but not fully charged NiMHs less than 100mA while the OC voltage is 1.37V per battery.
Does somebody have experience with NiMH versus alkaline AAAs ?
