What type batteries does it take and how long do they last. I know there are some scopes that use the up really fast.

They take the CR2032 battery (1 cell). The Millett red dot comes with an extra battery. My two Milletts are still new so I have yet to run down a battery. The CR2032 battery is common and fairly cheap, so just buy a few extra.

It takes a CR2032 I haven't had mine long enough to know what battery life is like

I'm not positive as I'm not close to my gun right now. But I do know it comes with an extra battery. And the battery life in my opinion is really good. And the scope overall is excellent.

Cr2032 lithium. If you remember to turn off the sight when not in use they will last months and months.

Requires flat coin sized battery that lasts a long time to light the reticle. Otherwise, just looking through glass

I do not know the exact time in hours and minutes, but my has lasted forever. I'm in and out of my gun safe alot, I leave mine on motion setting and have yet to pit new batteries in it. A+++

The light takes the 18650 3000mAh 3.7V Rechargeable Li-Ion Battery. You have to buy that separately. Try an UltraFire, they work fine. BUT...as for the light, see my review on this scope combo. The light is the worst part of it - you'll want to buy a better light. Still worth the cost overall.

Very quickly. Fastest w/ open sighted Mossberg 500, only a little slower with a ghost ringed 590. I just timed both; 2.6 & 3.2 seconds. I'm usually no where near that quick, waking in the small hours.

AA batteries do not work for more than 15 mins if you use tracking. The scope will operate but tracking will be very poor.

I get around 8 minutes of flying time with the standard batteries. Life shortens with dramatic maneuvers - rapid altitude, extreme banking and reversing, etc. Larger amp batteries are available, but I don't have any experience with them.

Two AA batteries are needed. Battery life depends on how often and how long you use the IS button. I am an avid hunter and part-time guide, so I am constantly viewing and assessing game, for long periods of time. I have gone through the batteries in 3 weeks to a month, sometimes less, but I use the button above and beyond the average person. I always carry two to four extra batteries in my backpack, so it's really no big deal. I have had the batteries last for a good 8 months during the off season. I believe that they could last a year or two, if used conservatively. The Canon 12x36 IS is simply the best binoculars I have ever owned!!!!!!!!!!!!!!!!!! Two AA batteries are needed.

The iScope requires four LR-44 (= AG-13) button batteries. Dollar stores carry packs or either four or eight of these batteries for $1.00! Cheap! And they last a long time!

The acog itself does not run on batteries, if you get the acog with the red dot on top for close quarters, the red dot does require batteries but should run around a year

Not sure of the exact number but I use mine to illuminate my Lyman case prep station and I can use it an hour or so at a time for months without changing batteries. The only time I actually ran them almost completely down was when I accidentally left them on for a couple of days. In my opinion the battery life is above average when using a quality, (not necessarily expensive) set of batteries. I buy all my batteries thru Amazon, including those I use in my insulin pump. Always buy name brand but they are still a fraction of the price of local sellers. AAA, AA, CR2032, LR44, etc. I use for optics and other things and at the price I get them on Amazon, I can buy enough to never worry about not having what I need at any time. I elaborate because a crappy battery will give short life in the best of devices. A decent or really good battery will give long, long life.

I use a marine grade battery and it has worked as long as we want to shoot. It's a little more expensive but worth it if you shoot much.

It goes thru batteries very fast.You can only get 18 holes if your lucky.That's the only problem I've had.

After about 300 rounds thru my MN, the scope stopped holding zero. It was great before that. Mine at least worked one day then just couldn't hold zero the next. Mount is a brass stacker and it's rock solid. I initially gave the scope good reviews but that was before shooting it a bunch.

The battery life is short because the light is so bright. Just use it as a Tactical flashlight and the bettery will last longer. Use regukar flashlights for general purposes.

In my experience, the ETX90 takes about 15 minutes up till half an hour to reach equilibrium. One of the great benifits of a small scope!

Only owed unit for about three months and battery indicator says I still have a lot of strength left. If you use range finder 40 times each round your battery should last about 250 rounds but I would think a third of that would probably be more realistic. Just put a second battery in your bag and you will be good to go.
