AA flashlight highlighted how much output current is better?

1, the full voltage range highlighting, 700 ma?
2, lithium electricity 14500 highlighting 700 ma, nickel metal hydride highlighting 500 ma?Alkaline AA highlighting 500 ma?

Strongest battery to use in a high drain device is a good Eneloop NiMH battery.
High capacity, high current and robust to withstand many recharges.

In cold cold weather, lithium primaries will work better but can not be recharged, single use only, most use NiMH and deal with shorter run times in cold weather.
Hope that helps?

Not sure what you're asking, but as general rule a good current regulated driver needs a certain wattage (VxA) to produce a fixed output. So for a fixed lower output on a NiMh, eg, 1.2Vx1A=1.2W, the draw on a 14500 would be ~324 mA, (3.7Vx0.324=1.2W).

As far as most powerful,

An IMR 14500 (AW for eg) is rated for 3.7Vx4A = 14.8W
An Eneloop 1.2Vx6A = 7.2W
An ICR 14500 3.7Vx1.5A = 5.5W
An L91 Lithium 1.5Vx3A=4.5W

Alkalines have very low capacity and very high internal resistance at high draws and therefore will perform worst at high outputs... but they will probably outlast all the above at the lowest draw levels. Also, boosting ~1.2V cells up to Vf tends to be less efficient than bucking 3.7V cells down, so an ICR 14500 and Eneloop will actually be very close.
