I want to get another pair of rechargeable batteries and rotate between the two -- Alkaline, Lithium, or NiMH? Do I need to make sure they can deliver a certain amount of amperage, or is there another spec I need to look at? Are there certain brands that are known not to fit? It's fairly tight in there.
Powerex has 9.6V 23mAh, and 8.4V 300mAh, for examples. Are either disrecommended, the one that's over, or the one that's under?
Tenergy and PowerAdd have some that are stated at 600mAh.
@justin
...(or anyone else)...can you give any insight on what the different voltage ratings can do to the amp? I know it would never hurt to have more amps on tap, except that might also affect its physical dimensions, but I do not know what underpowering or overpowering the voltage will do.
Wait, so the headamp site says:
So I'm confused about the alkaline, but it sounds like I can use anything.
