Hi, /p/

What batteries would work best and last the longest for my new flash? (pic related)

Energizer is the only brand that makes lithium AAs as far as I've ever seen.

NiMh are great for longevity and cost effectiveness (rechargeable) but they are unfortunately 1.2V batteries. Your flash should be 4 x 1.5V which is 6V, 4x NiMh gives 4.8V so ideally you would create a 5 battery pack which would give the 6V and the benefit of rechargeable.

for pentax, you could consider making your own quick recycle battery pack? use dummy batteries and an external pack?

I suppose that it is doable, but I'd rather stick with the simplicity of in-flash batteries.

I saw a graph whilst researching the battery issue that showed the decrease in voltage in AA batteries. Normal alkaline batteries start out having a voltage of 1.5V but steadily decrease past the 1.2V mark and into nothing.
NiMH batteries, however, remain consistently at 1.2V before sharply decreasing to zero.
This leads me to believe that it is not necessary to have a constant 1.5V in every battery. Also, the capacitor that the flash uses eliminates the need for a constant voltage supply; it just takes longer to charge with less powerful batteries.

tl;dr Alkaline decrease over time, NiMH remain at 1.2V
