How can I tell when the batteries in a Konica Pop are running low?

I’m using a Konica Pop with 2 AA batteries and wondered how to tell when the batteries are running out. Since the batteries power the flash and the camera’s automatic aperture system, I’m concerned that the flash might still appear ready but produce a weaker burst, causing underexposed photos. Will a low battery reduce flash power, or does it mainly affect recharge time? Also, what kind of battery life is typical with this camera?

The key thing here is that the flash isn't powered directly from the batteries. The strobe needs a burst of very high voltage — much more than that delivered by the batteries. So: the batteries charge a capacitor, and it's the capacitor discharge that makes the flash pulse.
This means that as the batteries drain, the flash pulse will still be basically the same, but the time to charge the capacitor between flashes will increase. So, your fear is basically nothing to worry about.

You’re probably worrying more than necessary. In simple flash cameras like the Konica Pop, the AA batteries do not power the flash tube directly. They charge a capacitor, and when the flash fires, that capacitor releases the energy needed for the burst.
So as the batteries run down, the flash output is generally still at normal strength once the ready light comes on. What changes first is the recycle time: the flash takes longer to charge between shots. That’s the main sign the batteries are getting weak.
If the flash won’t reach ready, or takes an unusually long time to do so, it’s time for fresh batteries. A dimmer flash burst while still showing ready is not usually the problem.
For battery type, use fresh alkaline AA batteries rather than cheap “heavy duty” zinc-carbon cells. With fresh alkalines, it should comfortably last through at least one 24- or 36-exposure roll in normal use.
