I know it's recommended, what would go wrong if I use Powerex 2700 mAh NimH batteries?

I put Energizer lithium AA in all of mine. Alkalines poop out at around +10F degrees. Lithiums keep going down to -40.

Plus, alkalines can (and, eventually, will) leak. I never leave them in any expensive gear.

Lithiums & NiMh, I understand, will not leak.

Many NiMH batteries are 1.2V, and those that are 1.5, can drop to 1.2V or so rather quickly. The CC needs 3V for the microprocessor to operate properly. Alkalines can last for many hours under constant use of the screen, if the LCD brightness is lowered, and Lithiums many more hours under the same conditions.

Also, lithium disposable AAA batteries have a no load terminal voltage of just a whisker under 1.8v each. That settles down to near 1.5v under load. Two batteries in series will deliver a full 3v over time, while NiCd/NiMh batteries start out under 3v for a pair in series, and alkaline batteries can dip below 3v as their ability to keep up with current demand falls off.

You're right.. they are 1.2V. CC is such a battery hog. :cry:

Anything with an LCD screen will have a hight draw. The AA's that ship with point and shoots may last 30 min. I have seen lithiums last 6 months. Best performance wise settings would be to lower the LCD brightness as low as you can get it. 10-30% is bright enough for most indoors, but would need to be increased in the sun.
