That's no lie and the reason the U.S. military requires that almost all of their equptment use a AA battery.  The EOTech, Leupold CQ/T, Flashlights, PVS-14, etc.

 

Also, a AA battery lasts for around 600 hours if all it's doing is illuminating a reticle (At least, for the Leupold CQ/T, only one I know about, obviously).  The tiny watch batteries found on the side of your standard illuminated civilian scope last quite a bit less.  If you have your CQ/T fully charged, you can have it lit up 10 hours a day for two months in a row without charging it or putting in a new battery.

You charge it through the ocular only.  I have not seen any reports of damage from too much light but these scopes are very new to the market.

How does Busnell recommend that you charge the firefly, through the objective or ocular lens? If hunting all day, say with the rifle slung, would that amount of sunlight have a negative effect on the reticle? Could long term charging with a Surefire?

You'd have the same luck finding those 3v lithium batteries for the surefire<BG>.

I'm not sure I understand your question. Are you referring to the performance of the Elites during daylight hours? If so, the Elites that are equiped with the FireFly reticle perform as any other scope which is the beauty of the design of the FireFly reticle. The FireFly reticle appears as any other reticle during the conditions you speak of. The beauty of the FireFly is that it needs to be ativated with a extermal light source to perform in low light conditions. The FireFly reticle, while seemingly simple in concept, was in a developmental process for approx. 9 years before perfected. Imangine applying an incondecent material to wire that is approx. the thickness of a human hair!!! Or while on that special hunt, try finding a CR2032 Lithium battery in the midlde of no where. To me, the FireFly reticle concept is a winner anyway you look at it. Like the frizzbee and Hoolahoop, I say to myself, why didn't I think of that!!!!

Want is the daylight (ie. normal) performance of the FireFly?  98% of my shooting will be normal with just an ocasional evening or night coyote hunt.

You will not harm the reticle with a flashlight and Chris brought up a good pointer about adjusting the beam from flood to spot. One more thing, and it might sound nuts, but apparently some people have attempted to activate the FireFly reticle using sunlight!!!! Really, I'm not joking. This bone headed move WILL damage the FireFly reticle.

Also as Roy touched on...the flashlight makes a big difference.  The little flashlight that comes with the scope works OK but using a top end light like SureFire makes a huge difference.  Also focus the flashlight's beam from a flood to a spot.  Our test show that just doing this decreases the amount of time to charge it and increases the amount of time it last.  This could also explain the varying results you are hearing about.

As I stated, and perhaps I was not clear, charge the reticle with a good light for two minutes and the reticle will be visible for you to make your shot. I charge mine about as close to dark as possible..Just keep in mind that the FireFly was not designed to replace electronic sights and it does not pretend to. Also, keep in mind that electronic sights as not as durable, weigh more and need batteries. If you have any other questions, please feel free to ask them. If I can't answer them we will shift them over to Chris. Also, remember that this is a best of both worlds reticle designs for low light hunting, not to heavy and not to fine so that you cannot see it in low light. One last thought, if you are "testing the FireFly" by activating it with a flashlight , then peering through the scope and there is ANY unnatural background light, the reticle will not glow as it should. The material that is used/applies to the reticle is very similar to the phosphoresce material applied to wristwatches/clocks if that helps you understand the concept on how the FireFly reticle operates.
