I ordered a 20-pack of CR2032 batteries from eBay. I ordered them from a US source, which means I paid slightly more due to sales tax. The total was $4.01.

There are so many types of batteries out there that it's impossible to say. I bought a bunch of rechargeable alkaline (AA and AAA) batteries 15 or 20 years ago, and found that the only thing they were really good for was a flashlight you didn't use much. NiCd usually bleed dead in a month off the charger and go bad quickly if they're left on it. Most of the early NiCd chargers were just constant voltage supplies. NiMh had the "memory" issue if you didn't drain them completely and recharge them fully, and still wouldn't hold a charge well unused for more than a couple months. A maintainer charger just wouldn't work or it would set a memory of 10% of a full charge (I had an Makita NiMh drill that did that). Li-Ion is definitely the way to go if you need rechargables, but they're either lower than standard voltage for standard D thru AAA sizes or higher for button cells, and a lot of electronics don't like their voltages upset. You also have to weigh the troubles of changing batteries and the significantly higher cost if you use rechargeable button cells, and they won't last 5-10 years on a charge like lithium cells do in a low-use device.

The CR2032 batteries have not arrived yet, but I also ordered CR2450 batteries the same day from a different eBay US source.

The CR2450 batteries just arrived. The unpadded cardboard envelope has two five-pack strips of CR2450 button batteries inside, which are larger and thicker than CR2032s.

The back of the envelope has a large sticker that says: "UN3090 - For more information, call: 800-424-9300" and "Surface Mail Only Lithium Metal Batteries Forbidden for Air Transport" UN3090 is a dangerous materials code for lithium metal batteries. The 800 phone number goes to a company called Chemtrec. It is their "Emergency Response Line."

I needed a new battery (LR44 equivalent) for my digital calipers. When I went to LOWES, it was $6 for three of them. I looked online and found a source on feebay for 40 batteries (Eveready brand) for $10, shipped. When they arrived, I noticed that they went out of date in 2020. OK, but at 25 apiece, how can I complain? I have 20 left, which I'm considering taking over to the senior center and leaving for people to use if they need them. Those batteries also work in a couple of LED flashlights that we have, but we've reloaded all of those in the last few months.
