Miracle Batteries

dougw

My first digital multimeter was a Micronta....here it is, fresh from my museum archives:

I remember being very impressed with its long battery life when I was using it decades ago, probably because it didn't use LEDs. But now I just turned it on and it powered right up, so I checked the batteries and they look pristine. The absolutely astounding thing is I believe these are the original Radio Shack Enercell Extra Life batteries bought when the meter was new! More than 3 decades ago! I did hang out at Radio Shack in the 70's and 80's but I definitely haven't bought batteries at Radio Shack for decades. I just measured the voltages at 1.54 V and 1.539 V.

Count me astonished, gobsmacked, flabergasted and totally blown away at how they can still be in this pristine condition. On the batteries it says they have a "miracle seal" - that is obviously not just hype. I have never seen any AA batteries sit on a shelf for a decade without dying and spewing their guts all over the battery compartment. I am going to have to see if these batteries are still in production - they are truly spectacular.

  • Wow!  That really is impressive.  I remember being part of Radio Shack's "battery club".  I guess I was only affording the cheaper batteries because I was always replacing them.

     

    I wish all batteries would perform this well.  There are so many forgotten places where batteries hide and unfortunately usually end up in a corroded mess.  Of course, nowadays it's more frightening with the failure modes of Lithium batteries image.
