Not the best batteries, but not dead either

Because there was no expiration date, and a 2012© on the packaging, I decided to do a simple battery test with my multimeter. Note that, even though they're a bit old, these are disposable lithium batteries, not alkaline, so they ought to have an 8-10 year shelf-life with minimal degradation These batteries came out of the package at ~3.2V, which is about normal for a new battery, but doesn't mean they're in great shape either. After testing one on the ammeter for < 2 seconds the current fell immediately, and voltage testing afterward showed it was down to 3V even, which seems excessive even for an older battery. For the comparison I performed an identical test on a Duracell battery of the same type, which I bought at the drug store (unfortunately, they only sold Duracell brand, so this is necessarily a cross-brand comparison also) which had a 2014© and an expiration date of 2024 on the packaging. For the Duracell, the voltage out of the package read 3.3V, and after the brief current test read 3.29V. Unfortunately that single store-bought Duracell battery cost ~$6, almost as much as this pack of 5. For most low power applications, which is mainly what these button-cells are for anyway, they *ought* to work just fine, although they'll likely have a shorter life. But if you want peace of mind, I'd suggest just picking these up at your local hardware/drug/grocery store since they're common as muck these days.

DO NOT BUY

I received my batteries & all of them are dead. They do not have an expiration date on them. The manufactured date is 2016. I did not try to send them back because I am disabled (which is why I order online) & it would cost me more to pay someone to return them than the batteries cost. I order batteries from Amazon all the time & this is the first time I have got got bad ones.

Read the other 0ne-star reviews on dead batteries.

Read the other 0ne-star reviews on dead batteries. Received the pkg of 5 batteries today. Opened two both tested low/replace (as did the one I wanted to replace). Both performed poorer than the one I was replacing. I can’t tell if counterfits, very old or just junk - but useless. Sad for an Amazon Choice product.

Savings vs. Function lesson learned

I'll be the first to admit you can find batteries everywhere and probably get 100 for the price of these. Although. I'd also be the first to admit that I really didn't believe you get what you pay for too. I had a couple tire gauges that used the CR2032 batteries and put new, metered checked, batteries in them and thought the guages were faulty. The RMA and cost to send back the tire gauges under warranty were about what I could buy them new for and was infuriated. So I bought a new tire gauge and put the batteries into the old tire gauge and it worked flawlessly. What the? So out of curiosity I bought a pack of these to try and sure enough, the two gauges I was going to warranty return worked fine. Wow! Life lesson learned, sort of.... For those fake votive candles, they will still get the cheapo CR2032 batteries as they would work at half the power. Important devices will get spoiled.

Don't waste your money!

Fool me once, shame on me. Fool me twice and you get a bad review! I had purchased batteries from this vendor previously and received a pack of dead batteries. I contacted them and they sent me a replacement pack of usable batteries accompanied with an assurance that all of their batteries were good. So I ordered another pack and every single battery died as soon as a load is applied to it. Save your money and buy fresh batteries at your local store.

Fresh batteries.

These seem to be genuine Energizer batteries, and they have worked much better than the generic 2032's I've purchased in the past. The generic batteries I've been using only lasted a month in my Thermapen thermometer with light use, but these have been going strong through several months of grilling. They don't have an expiration date printed on them, but there is a two-letter date code on the packaging. I contacted Energizer to find out what the date code meant, and they said it indicated a manufacturing date that was only 4 month before they arrived at my door from "West Distribution". I haven’t had any problems with these batteries leaking, corroding, or otherwise failing. They all have a uniformly shiny finish, and look high quality. It’s hard to test button cell batteries, as without any load on them, a voltage meter will almost always read over three volts. With a 15K ohm load, these batteries read 3.0V, which agrees with Energizer’s product datasheet. I also tested one under a heavier load by shorting it with a 100 ohm resistor for two seconds as shown on the datasheet, and the voltage drop was exactly as predicted (starting at 3.25V, going down to 2.8V during the pulse, and recovering to about 3.15V).

All batteries old or defective with insuffient voltage

Don’t order these if you want batteries that work! Entire package was of batteries with 2.5v charge (tested), not the 3v that new 2032 batteries should have. Will not work correctly in many devices - consider yourself forewarned.

Batteries may be old

Of the 5 batteries, 3 are less than 3 volts with no load. They all should be over 3 volts no load when new. I tried to return them and got this message: "This item isn't eligible for return: For safety reasons, items containing flammable liquids or gases can’t be returned to Amazon. For more information or help, please contact us." These are lithium batteries and don't contain flammable liquids or gases. I have returned products containing lithium batteries in the past with no problem.
