I'll admit I have zero experienc with battery powered optics. But I do recall reading that the Remington system was to use a 9 volt haha. Not the same as a massive lead acid vehicle battery or an airplane, not even remotely comparable.
What's the coldest you've ever gone shooting in? I can tell you from real experience a 9 volt in a chronograph doesn't take long to DIE DIE DIE in -20 to -40 ranges. Neither does the one in your cell phone if you leave it out in your car for an hour or two by mistake.
And give it enough time…if you're not starting your vehicle on a regular basis and it's subject to cold for a long time that battery weakens. And the battery works because it gets recharged by an alternator that ultimately depends on combustion. Dare ya to find out how long your truck battery survives our winter with no alternator (I mean it dies regardless but it dies MUCH faster in this. Also a reason why I'll never own an electric vehicle - they're fine for California. There have been real incidents already in my home province of suckers who bought the stupid things and got stranded in the middle of nowhere (which is most of Saskatchewan
) because, you guessed it, real cold weather KILLS batteries. One lady had to get her car towed in (and rescued from freezing to death at night) when her electric car didn't even make it half the distance it was supposed to be able to.
It's not public stubbornness or bad marketing. It's a bad idea for any rifle that has to work no matter what. Again, fine for target guns. Not for field guns, be it sporting or military. Primers have proven their reliability (tho they are hard to find, I think I need a flintlock)
Oh!!! Your comparison, invalid as I may deem it, nonetheless gives me a great and ridiculous idea (I have lots of them, mostly bad
)
AN ELECTRICALLY FIRED RIFLE….WITH AN ALTERNATOR!!!!!
Attached to the muzzle, instead of a brake or suppressor, we have a big can that contains a turbine that the gas from the muzzle blast spins hard, like a turbocharger, and this is connected to a whole magnet/coil set up like an alternator to generate electrical current which is then used to charge the gun's battery.
