Left the batteries in for about 18 months. Got the gun out to shoot and the sight diden't work. Opened it up and  ! What a mess. Guess you really don't leave batts in stuff till you need it. Cleaned it out with electronics cleaner still don't work. $$ down the drain.

LOL Aimpoints are quality optics, as are EOTechs. Use what you want, but the fact that you didn't check on some installed AA alkaline batteries for 18 months doesn't reflect poorly on the quality of the EOTech. BTW, before you start a rant against Ford, note that your engine oil needs to be changed every now and then.  |

Wait.. let me get this straight.. You're blaming Eotech for using AA batteries (on the unit you bought) and praising Aimpoint for not using AA batteries (on the unit you bought). Ummm.. (Not to make you sound stupid) did you know that Eotech has units that use N type and 123 Li batteries? AA can and have leaked, but it can be for any other product such as a remote control, or a child's toy. Eotech does not make products that are suppose to be resistant to that type of problem.. no company does to my knowledge. |

Aimpoints are very nice. I buy them on closeout whenver i can. But they screwed me on a repair return so i'll never pay full price for one. Now i buy AA eotechs from brownells with the 10% off shot show cvcoupon and trade discouns its less than $330 and brownells warranties it forever. |

There is probably a moral here for all of us. Even though AA's last a long time in an E-otech, It's probably not a good idea to let them sit for 18 months in a less than new condition. It would especially be problematic if they were near the end of their energy level when they began the 18 month storage. Probably a good idea to replace slightly used batteries on a schedule if the device is going to sit a long time. Not advocating letting the unit stay empty, but advocating only storing with mostly new batteries. Would probably also not use Wolf/off brand AA batteries either. Just a major brand that could be addressed if their batteries leak. |
Yep. Lithium AA's and change them every year at the first of the year. |
Edit - post 223!  Good post. I just took batts out of everything due to this problem but in a shtf, do you really want to take the time to put batts in your weapon? That bothers me. So just making sure the batts are new every year should mitigate the problem? Has anyone here had this happen with 123's? |
I have left batteries in my aimpoints for years...with them running the whole time EO techs are good optics but they really do have some problems. First and foremost, you have the 2 AA batteries sitting parallel to the bore. Therefore, every time the weapon fires, the batteries are compressing the spring that holds them in contact during recoil. Eventually, with enough compression cycles, those springs grow weak and will start allowing the optic to flash off when you fire. The batteries are losing contact for a brief moment. The springs are not a user replaceable part... The other problem I have seen with a lot of EO Techs is that the adjustments are not equal...do a box drill on paper and you will see it. at 50 yards, go up 10 and shoot, right 10 shoot, down 10 shoot, and left 10 shoot. You will not be back at your original point. Lastly, they are not paralax free. Zero the optic and then at 100 yards, put the reticle in the upper left corner of the optic and fire at the same target...you will be about 8 MOA off.

Do us a favor and post pictures. Until then, I'm going to call BS. Not that I don't believe it could happen but your posts sound more like somebody who just wants to bash Eotech and promote Aimpoints rather then somebody with a real issue. You threw the batteries away and "destroyed" the Eotech so much so that you can't even sell it now or send back to Eoetch for repair? If you are telling the truth then I still have no sympathy for you as the money that you're out is your own fault IMO. |

just a note. if you use brand name batteries - energizer, duracell. you should not have a problem with leakage. if you do and the batteries leak in the device. you can send it back to the battery manufacter and they will repair, replace or cut you a check for the device. Ive done this in the past and they have always made it right. but you must sent the batteries to them to prove it was their brand. They are good companies that take pride in their products. |
This is worth repeating. It would suck to screw yourself out of getting a repair/replacement. |
