Drop my little friend on a adjustable bench supply. Wow that thing draws current! It went to about 750ma at around 2.87v while charging. Sheech!
Q4 is getting a workout!
Just for giggle here are the spects on Duracell stock Alk battries:

I think that a std set of battries wont do 750ma. Both on voltage drop and that much current being drawn. Need to pop a line and measure.
Looks like the 800ma 3v will go back and need to design a pritty good heatsink for the adj regular version. At least it can take 1.5amp max.
