EoTech corroded battery help

[45.308]

Went to the range yesterday and Eotec 512 did not show life life. Popped open the batter compartment to find the right AA corroded and white corrosion inside the battery compartment. Any tips on how to remove the corrosion? I am thinking a baking soda flush.

I stalled new batteries and it worked just fine all day.

Will contact Eotech if they answer.

My one time using Energizer batteries Vs Duracell, not that this matters just never had an Duracell corrode. The battery in question is less than a year old. I usually replace all batteries every 6 months in all electronics but time got away from me but still never had a Duracell do this.

Thanks

I would just brush it off and swap with alcohol.

Use lithiums next time.

For corrossion I've used the eraser part of a pencil to best scrub it off and gotten results on the contacts.

Take an old tooth brush and rubbing alchol to scrub it out. that should remove the vast majority of the corrosion. You dont really want to introduce water to it and also avoid any type of wire brush as that can cause damage to the finish.

If you do a little research you'll find it is a very common problem with the 512. Feedback has been that neither L3 nor the battery manufacturers will take any accountability. I learned of the issue second hand and have been able to prevent the occurance with my Eotech(s). The only preventative solution is to store without batteries or change fequently if you are using it on a ready weapon. A paste of baking soda flushed with silicone spray will clean it and hopefully you have no lasting damage.

^ ^ ^ this is why my one and only EOTech is on my toy gun with the batteries removed after each outing. EOTech's attitude was "too bad". I found out from EOTech the sight drains the battery - even "off" - to maintain memory of last intensity setting. (rant off)

Carefully remove all the connector guts (contacts, springs, bridge, rubber base) and clean with water or alcohol and tooth brush. Fortunately on mine, there was no corrosion on the sight, only the battery compartment. If the springs and contacts are trashed, EOTech might replace them.

Good Luck

BTW, I switched to Aimpoint - batteries stay in and the sight has never failed me.

Re: EoTech corroded battery help

thanks everyone, I will look into the alcohol, I was taught to use baking soda to neutralize battery corrosion.

This 512 is 4-5 years old and I ran nothing but Duracell in it and never had any issue, batteries installed the whole time. Duracell's were in all my electro's. This past May when I bought some batteries for emergency kit, they all were Energizer. Was that the cause or not, no matter I will go back to Duracells. I ran cheap Sportsmans brand in flashlights with spare batteries stashed everywhere for well over a year and never had one let loose like this. I considered lithium and may go this route.

Nothing on the glass or outside, just corrosion right side battery compartment.

again thanks

I believe that the corrosion is acid. Baking soda will neutralize it. I have done that with car batteries. Baking soda and a little water.

^ Negative on alkaline batteries. Wet cell car batteries use sulfuric acid for electrolyte, and baking soda does neutralize and clean. Alkaline batteries leak potassium hydroxide, a base. In reality, a light acid (vinegar) cleans, but is acidic. Personally, I have used water or alcohol on battery connectors. I'm not too keen on using an acid on electronics.

Buy an Aimpoint, problem solved

Re: EoTech corroded battery help

Guess I've been lucky. I've had a 512 for about 4 years and tun nothing but lithiums in it. No problems or issues.

Re: EoTech corroded battery help

As mentioned above alcohol is the spolution, use distilled technical 96% alcohol, only thing i would ever wash any sensitive electronics in.
And go with lithium next time, better service life, more dependable and corrosion will be a non existing problem.

Re: EoTech corroded battery help

I was told the acid to use, was 'citric acid'. As in, use simple Lemon Juice to clean out corroded Alkaline battery crud.

I learned it the hard way, and it worked for me. Enjoy.

And yeah, use the Lithium batteries. They're more gooder!

Re: EoTech corroded battery help

Hmmm, This exact thing happened to me and thought it was a "freak, one time occurrence"...If you'll excuse me...I'm going to go pull the batteries out of my EoTech.

Re: EoTech corroded battery help

Ya, thanks. I didn't have any lithiums handy when I bought my 512 6 months ago. I bought some but never got around to putting them in. It was working fine, why bother, right? The alkalines were fine, no leakage. But I'm glad I got the reminder.

Re: EoTech corroded battery help

I had this same issue with mine. I went through two battery compartments before I said fuck it, fixed it one last time and sold it. I'm now an Aimpoint only kind of dude for that reason. And the battery life on Aimpoints is significantly higher, especially on the micros.
