  • Any idea the mAh rating for these? I put 2 (dollar store sourced 4/$1) of these together to make 3v and light a superbright LED and its been dimly lit for about a week.

    • e wondering: These should fit the 12mm holders listed below. Or at least in theory.

      The Practical Working Voltage for these is actually 1.15 V., so using 3 of these probably would’ve been better.

      Not sure about the mAh rating though… But would really like to know as well.

  • For anyone wondering: These should fit the 12mm holders listed below. Or at least in theory.

  • not quite the bulk pricing of other sites, but im sure sparkfun has a better quality source than such resellers :) last set of 100 from batteriesandbutter.com 22 of them arrived dead. :)

    • Don’t even get me started on that website. Last week, I bought 100 tubs of butter, and 22 of them turned out to be batteries!

    • We knew we couldn’t compete with big battery stores but if we needed them we figured some folks would need them as well (basically anyone who has digital calipers). That said - “batteries and butter” is the best name for a business I’ve seen for a long time!
