Will Eotech ever work on improving battery life?

[Kenshin]

Just fishing for news here.

Aimpoint's M4 model has around 8 years on a single AA, correct?

Will any future Eotechs have more than 600-1100 hours of battery life to match?

If I aint got nothin nice to say Ivan said, keep it to myself

So, I aint saying nuthin

Aimpoints do not run on an AA, they run on a DL1/3N battery.

Later Aimpoint designs' batteries outlasted the original late 90s ones by a fair amount.

EoTechs do just fine on their AA or size-N batteries. I haven't changed mine yet.

The Aimpoint COMP M4 does use AA battries.

I am sure Eotech will come up with something eventually for longer battery life but comparing them to the aimpoint is not quite fair.

The Aimpoint uses a led diode to project the dot while Eotech uses a laser to produse their reticle which requires more power from what I have read online.

Ahh, thanks, I stand corrected. Didn't know they'd changed - my Aimpoints are the older 1999ish vintage Comp ML stuff. Reasonably good battery life, just keep a spare or two in your buttstock or pistol grip compartment.

Um, small low power "lasers" are in fact special LEDs. They may not be quite efficient per as regular LEDs, but they are LEDs the are coherent emitters.

DO you leave your EO tech on constantly? 1100 hours translates to about 5 or 6 weeks left on. Lets say you used your EO 12 hours a day every day. It would last you 3 months that way on one set of AAs. Just carry some extra batteries if it bothers you. The AAs are easy to find anywhere. On a Sidenote: The Military red dot of the Russian special forces(spetsnaz) is the Kobra scope. It's manufacturer listed battery life is 100 hours(4days). Now, THAT is short.

I ran out of batteries on my Eotech twice.. and I don't even use it that much. Eotech says 1100 but I am seeing around 200. I leave my Eotech on the whole time when at the range. 20 times 4 hours each time is only 80 hours... then you might another 80 hours playing around with it in the house. Granted this is at the brightest setting, but still......

I am going to try lithium AA batteries at $10 a pop for a 4 pack to see if that extends the life.

One complaint I have about the Eotech is it turns off by itself after 4 hours. I guess this is a good thing, to extend battery life, but it does not make your rifle instantly ready. With the Aimpoint, I can throw it in the back of the truck for 6 months with it on... be ready to use at any time.

I have the older ML2 and I leave it on all the time, so far I have yet to replace the battery.

Actually if i remember right, activate the sight using the left button equals 4 hrs of run time. Activate the sight using the right button equals 8 hrs of run time before it shuts off.

ok cool. I'll try that. Be nice to leave it on at least over night.

I dont know about the Eotech's but, many eletronic devices have much less battery life at "full power(brightness)" than at "slightly less than full power"

Fwiw, I've had problems w/ my econo AA batteries die in my Eotech. Specifically, Kirkland (Costco house brand) alkalines. Another shooting buddy has had similar problems w/ his using Kirklands. I guess they can't stand the recoil and you lose all power.

Found on Eotech website's Troubleshooting FAQ that is a known issue with 'some brands' and that they recommend Energizer brand for max life/reliability. I would assume Duracell's would also be fine.

I use Duracell, and results not so good.

My Eotech 552 hasn't had battery problems in the few years I've had it, but I've had a ton of problems with Kirkland batteries, especially leakage. I quit buying them years ago after trashing some stuff they sat in for a while. Only name-brand for me!

With Lithium AA's it's not too bad.

Setting

I read somewhere that the 1100 hours battery life the manufacturer lists is if the EO is set at 4 settings down from the brightest one.

How about an experiment?
Anybody wanna volunteer to test there EO at this setting using lithiums and logging the progess of the reticle every 8 hours?
