    CR2032 Batteries

    I have to order some new CR2032 batteries for my various red dots.

    What brand should I get?

    From AJZ's lecture during last year's ASP National Conference:

    "If you're gonna run a red dot, I highly encourage you to utilize Duracell batteries. The reason I say Duracell batteries? Duracell has a very tight spec on their batteries. They do a lot of good QC that most of the other companies do not do. So when I get a 2032 battery from Duracell, I can put my calipers on it and go, 'yep that's plus one minus zero, oh this one's good, this one's good', so when I put it in I know it's going to contact the battery contacts. I cannot say that with other companies -- coughEnergizer."

    "Sony's are great. Sonys are very good batteries. You could totally use Sony batteries, they're my second choice of battery."

    Duracell

    ...only Duracell.

    They're sized to the correct spec (so they fit the contacts and don't cause flicker) and they stand up to recoil.

    It isn't even worth considering any other brand.

    Since the consensus is Duracell, Iíd suggest checking Costco if you shop there; they have a card with a dozen batteries for a pretty good price.

    Duracell





    Renata













    ...everything else (did not test Sony but they arenít common around here).

    I tested Duracell, Energizer, IKEA, new bitter Duracell, Panasonic, and Renata batteries. As of a week ago (Iím on vacation and this is the first time in a year Iíve given up on daily checks) thereís still one of the four Duracell batteries thatís been going on max on an Aimpoint H2 for over a year. Thatís multiple times longer than anything else Iíve tested and only one of the two Renata batteries (the first died at about 100 days) is still going at probably 150ish.

    Woohoo! I found a place online where I can get Renata CR2032 batteries for just 27 cents each! 30 cents cheaper than anywhere else!

    I just have to buy a tray of 200...

    I've vowed to never buy another Duracell after multiple lots of their alkaline AAs have destroyed my shit by leaking.

    Panasonic, Sony, and Cellewell for me.
