In January I bought some
CR2032s from seller "
Energizer" on Amazon.
I went to install them in some data loggers I have today and they died within minutes. The counting data loggers draw on a few microamps of current and a 2032 normally lasts for about 8 months monitoring my well. It has been 9 months since I changed the batteries and they were still running, but the batteries were getting low as expected. They were working fine, but do not have enough energy left to continue being used.
I downloaded the data from the data loggers using the existing batteries. I then replaced the low batteries with what I thought were new good batteries, but the new batteries did not and will not work. I tried multiple batteries from the package and tried both data loggers I have. Unfortunately none worked. Although I am in a remote location, I do have a multimeter, so I probed the circuit and within 2 minutes the voltage dropped from 3.17V to 2.2V.
I thought when I bought these batteries thought they were genuine. However upon closer inspection they appear to be counterfeits.
The Amazon vendor is listed as "Energizer Brands, LLC."Here is an image of the one of the good ones I removed today that has been working fine for 8 months:
This is an image of one of the pieces of crap I tried today:
If you compare the fonts the crap batteries appear to be counterfeits. They also scratched up quite a bit more with only one insertion and removal.
Here are some images of the package:
These batteries are complete crap.
This is my second time getting burned on batteries from Amazon. I had the same issue about 4 years ago with some other 2032s.
I will no longer being buying batteries from
Amazon. I will stick with
B&H as my source.
