So a question: How many hours do you
get from a set / charge of batteries? The lights I have use 4AA
batteries in the headlight and two AAA batteries in the rear red blinky
light, which I always use in the always on mode, no blink. I don't know
the model numbers off the top of my head although I guess I could look
them up.

Complicating the answer to that question is that flashlight battery
powered lights gradually become dimmer with use. So as a general
rule-of-thumb I halve the mfgrs' ratings to get an approximation of
/useful/ battery life. It's easy to be fooled -- the lights may appear
bright at first when turned on, and then they'll dim with continued use.

Use rechargeables (NiMH). Not only will you save money over time
and stop creating unnecessary toxic waste, your lights will not dim as
they do with disposables. The discharge curve (volts/time) with
rechargeables is a lot flatter.
