I'm down to my last CR2032 Lithium battery, stored in my fridge for 10 years now, from a 6 pack I bought off ebay (from Asia) in Mar. 2010.
So, I go to Ebay a few days ago and buy a set of 10 Panasonic CF2032 Lithium cells, "**FRESHLY NEW**, "made in Indonesia." I get them today. I test them with my quality Fluke multimeter and the 4 or so I randomly tested by poking through the card were ~3.20v. The 10 year old one in my fridge tests the same as when it was new at 3.34v. The one that came in the chest strap heart rate monitor I received today tests at 3.36v or so.
So I'm wondering if I should make an ebay complaint that these "FRESHLY NEW" Panasonic batteries are substandard.
The cards say PD 10/2019, ED 09/2029, so doesn't look like they've been sitting around. But it seems to me that Panasonic CR2032 should test higher than 3.20v. Am I right?
The CR2032 batteries I bought in the past were off ebay and shipped from Asia and this was 2010. I have one of those left, it's been in the fridge all this time, has open voltage 3.34v. The listing said Maxell. I bought the pack of 6 and paid $0.99!!!Why are you buying batteries from eBay??? Wouldn't it be obvious that they will be substandard, considering that anything sold on eBay that is cheaper than market price must have been used?
Never buy from eBay for anything that relates to a health device, or a health device uses. If you don't want to go to a store, there is Amazon or even the battery manufacturers website.
I'm glad I started this thread. It's been an education for me. I had no idea that the market on ebay is flooded with knock offs. There is info in this thread suggesting that some available through Amazon are definitely suspect as well.Most cheap batteries off Ebay are garbage. They may say energizer but they are knock offs. I used to buy them. 10 for $1.5 sounds great but they only last a few weeks in my clock whereas real ones from Target, Walgreens last nearly a year.
I bought a cheap head light for my bike off Ebay, from New Jersey last June... $8.95, and it looks pretty much like ones costing more than 2x as much on Amazon and other ebay listings. Lithium rechargeable, and I've recharged it a couple times. Works great. Came with a little tail lamp that runs on a CR2032. That tail light has 3 flash patterns to pick from, flashes RED. It's still going on the original battery, which is kinda amazing. I don't ride at night much but must have used that tail light over a dozen times on rides averaging over 15 minutes.Most cheap batteries off Ebay are garbage.

I’ve never bought any off amazon but a lot of third party sellers of batteries and SD cards sell knock offs. One guy even told me that he received a really slow and probably fake SD card that was sold and shipped By Amazon. I hope that isn’t true.I'm glad I started this thread.

Amazon commingles (some of) the product inventory that it fulfills, whether Amazon or a 3rd party is the seller. So it's impossible to know for certain where inventory came from, and challenging for a layman to know if it's legit or not.I’ve never bought any off amazon but a lot of third party sellers of batteries and SD cards sell knock offs.

I bought a set of 10 Kootion 16GB SDHC cards at Amazon for $28.99 less than a year ago. I tested them and one tested bad. I complained and they had me send the whole set back to them and they supplied me with replacements, which tested OK. I've been using them with success.I’ve never bought any off amazon but a lot of third party sellers of batteries and SD cards sell knock offs.
