Did not fit

by Evan, from LA, United States Written on April 17, 2022
Battery cap does not fit. Seems too shallow to fit the 2 AA batteries. Doesn’t seem to be a genuine replacement part. Once I put in the batteries, they stuck out half an inch, not allowing compartment to snap closed. I don’t want to force it so I’m sending back
Pros:
  • None
Cons:
  • Did not fit with batteries installed.
Would recommend: No

Direct replacement OEM battery chamber.

by Mitchell, from OH, United States Written on July 30, 2021
This was exact fit replacement. I am very pleased with this purchase! It is the original manufacturers part and truly at a great price. It made my expensive Eotech sight like brand new! Be sure to select the correct one by your manufacture date of your Eotech sight. Thanks!

Easy to install

by Roger Kronick, Verified Owner from NV, United States Written on July 6, 2021
I was worried that my EOTech 512 was damaged beyond repair due to battery corrosion. I ordered this Battery Cap along with a Battery Sight Contact Replacement Kit. Price was very reasonable and shipping was very fast. I had my doubts that it would work, and thought it would be a difficult procedure. The Cap simply pops right in. The Battery Sight Contact Replacement Kit actually took much longer to read the instructions than the actual replacement, which took less than two minutes. I thought....can't be that easy, this won't work. Then I turned on the sight and BINGO, no worries. PLEASE NOTE: There are two washers with the kit, and it might look like you only have one but they are tiny and stick together. Just separate them.
Pros:
  • Affordable
  • Works well.
  • Easy to repair/replace
Cons:
  • None
Best Used for:
  • Repair damage due to battery corrosion.

The item I ordered was on back order but it was quickly replaced and shipped. EO Tech does not make the 552 replacement parts that I could find so it was nice that optics planet was able to get one still.

EOTech Battery Cap for 512/552 Sights

by Talon, from WA, United States Written on August 22, 2020
THIS PRODUCT IS AN EXACT FIT FOR THE 512. THIS PRODUCT PLUS THE HOOD REPLACEMENT CAN MAKE YOUR OLD EOTECH OPTIC LOOK BRAND NEW. IT LITERALLY TAKES 30 SECONDS TO SWAP OUT THE OLD CAP. I ALSO RECOMMEND GETTING A NEW BATTERY TERMINAL KIT TO KEEP YOUR SIGHTS UP TO DATE.I RESTORED AN ORIGINAL 512 FROM 2008

Replacement EOTech battery compartment

by drgearke, Verified Owner from IA, United States Written on May 17, 2020
Got my EOTech 512 up and running like new again. Batteries got old and corroded the contacts in the old compartment. New design so you don't lose the springs and rubber donuts. My only grumble is that it took 10 days to get something that could've been tossed in a padded envelope and mailed.

Fixed the problem!

by M, from FL, United States Written on May 11, 2020
Thank you for providing this product as the battery contacts/boots in the old cap had corroded out. Put new batteries in this unit, snapped it in place, and presto we have light. Then I removed the batteries before putting up this time!
Pros:
  • Affordable and Effective
Cons:
  • None

EOTech 512 Battery Cap

by Rick, from GA, United States Written on March 10, 2020
Not much to say about this part, I needed a new battery cap for my EOTech 512 and Optics Planet had the best price. It fit perfectly and it helped me to realize that my old battery cap was not what was causing my 512 to not work. Back to the drawing board!
