Energizer ECR2032 3-Volt Lithium Coin Batteries (20 Count)

Despite not having labels or writing on the packaging, the batteries come in generic white packing. It is stamped with a Chinese phrase that reads "Lithium Battery", "CR2032", "3V", and "CHN". When all six batteries were plugged into the votive candles, the first six batteries we used worked fine. It is not known what their voltages are. In the second candle I found that the next two batteries would not work, so I got out my voltage tester to check them. One of the 14 remaining batteries came back at 3 and was ok. One was on the left, two were on the right. Five had values too low to be useful, and eleven had values lower than zero. Observe the following. I couldn't tell how old the batteries were from the packaging or from the batteries themselves, so I can't tell how old they Despite the fact that the set of 20 batteries contained 20 batteries, only seven were usable. These batteries did not appear to be ECR2032 batteries from Energizer. It would have been better if I'd immediately returned the not-energizer ECR2032 batteries but generics, once I realized they weren't Energizers.

I had no issues with the first pair of batteries. I had one in a Wahoo bike sensor for two months or so. In the last four weeks, 4 out of 5 batteries have lasted less than a week. My first test with the batteries was with the BT 168 tester, before I inserted them, and they barely registered in The packages are dated 2016 and are written with a copywriting style. In addition to the four random batteries, I tested another four as well. These batteries are either old fakes or old batteries claiming to have an 8 year shelf life. There is no doubt that they are old batteries sold as new. This experience has left me feeling very disappointed. To be more precise, I will eventually resort to purchasing these locally unless I can receive some assurance that they are.

As I was testing the four packs, I noticed that all of them were depleted, but the cells themselves do not seem to have a date stamped on them, but the package says (C) 2016, so they probably can't be too much older than a year. The battery pack which I bought was to replace the batteries in the remotes I use for my vehicles, but after trying my first battery it lasted only about a month, I tested each cell from each pack and it worked fine. The Energizer datasheet for the CR2032 indicates that these batteries are capable of sustaining a 100 Ohm load for 2 seconds, but should not drop below Eight volts. As soon as I opened the package, I grabbed my DMM and a 100 Ohm resistor to load test the batteries. As soon as one cell was tested, it dropped instantly to two. The first one dropped to 45V, the second one was similarly reacted to, while the third one dropped A 65V power supply and a 2A power supply make up the quartet. A 62V system. Since I have now passed the return date, I cannot return these cells. I guess I'll just keep swapping batteries in my remotes every month or so until they run out. Such a waste as the original remote batteries lasted for.

There was no reason for me to make a mistake. One did not have more than two of any 20 that I bought. The most common value less than 2v is 4v.

As I read a few reviews and watched a few videos, I was a bit concerned about these batteries. My first reaction was that they arrived within a short period of time. Secondly, I recognized the expiration code is ZA and contacted Energizer immediately. According to them, code ZA is a current battery since it was produced in May 2018! There are no broken seals on any of them and they are all brand new.

Buying from Amazon is much cheaper and just as effective as buying from a store. Since we used nearly a dozen of them, and not a single one has been defective, I decided to buy them in bulk online instead of our local big box or grocery store. We've purchased nearly twenty of these and there have been no problems. There is a bonus As well, these work for the key fob on my husband's car!.

I decided to test one of each 5-volt battery made in China because they were made in China A multimeter should be included in your pack. only a 3, which was very low. I read a high of 3 volts and a low of 18 volts. You need 38 volts to operate the instrument. As a result of these results, I am confident that the batteries will perform as expected. As quality control continues to be strict, I hope that it will remain so.

I was sent Energizers on both occasions as well. LED tea lights and other ambient lighting are some of the uses I have for them (A family member is unable to use real candles for health reasons. )
To date I would guess that I have gone through 30 2032 batteries without any discharged or dead batteries occurring. In addition to lasting and being affordable, they are a good deal more durable than those purchased elsewhere I bought 2032's from the dollar store, so they don't last so long. I'll buy from them.
