So last night I was sitting in the box waiting on a hog. I had just replaced the batteries in the Photon XT 4.6 before I went out. It was cold- 31 degrees. I had mounted a new IR illuminator to try out, so I turned on the Photon - not the built in IR- just the sight- and the battery showed 3/4. I scanned for about 30 minutes and the battery indicator was dropping the whole time. Then the LED turns to red, and the battery shows 0. About that time, of course, a hog steps out. I shot him, and the sight turns off. Turn it back on, heís down. I have some rechargeable lithium AAs on the way, these were just Alkaline Energizers. Last week, when it wasnít near as cold, some Duracellís lasted 3 hours.
So whatís the recommendation for the XT? Reading up it looks like thereís really no easy way to add external power.
Whatís the normal time people are getting from rechargeable lithiumís?
May be time to upgrade to an RT....
