is an extreme drain test.
If you are only getting 30 shots out of your batteries, there is either something wrong with your batteries or they are not being fully charged by your charger(Or that Kodak cam uses like 25Ah:Q)
I get
300 - 500 pics out of my Powerex 2200's and A60.

I tested batteries in sets of four, as they're most commonly used in digicams. I used a total load resistance of about 5 ohms, providing peak discharge currents of a bit under an amp (1000 milliamps), equivalent to a fairly power-hungry digicam running with its LCD turned on in capture mode. This isn't an absolute worst-case test, but should be pretty representative of what batteries will encounter with real-world digicams (as opposed to the sort of gentle discharge curves used by manufacturers when setting the mAh ratings). For the techies out there, this is a discharge rate of about 0.6C for 1600 mAh cells, as compared to the 0.1C discharge rate used to determine the normal mAh rating of batteries.

I want to see the worst case.
Edit: I'm taking pictures now to see how many it will do.[/quote]Ahh.. Yeah, guess I remembered wrong.
Still, though.. 30 pics is in no way normal. That's ridiculous.
If your cam has an A/C input, look on it and see how many amps it draws if it says. I bet its like 1.1A.
According to Image Resource, it should last about 70 minutes with the LCD on and 1600mAh batteries. I don't really know why they use minutes instead of images captured.. seems kinda silly.
