Are they they the same thing?

I believe so...if I remember correctly, I had the same question a few months ago when I had to change the battery in my bike speedometer. It called for a 123, and all I could find at Wally World was the 123A. In any case, it was the same size and it works fine.

Now with more A!

(Which in electrical parlance means it has more amps! )

rechargeable li-ion cr123a are usually marked RCR123A and the voltage is 3.6, not 3.0

123A as in alkaline vs lithium or silver oxide perhaps? Just a WAG.

Okay, sounds good. I'm not interested in the rechargeables since they have a different voltage, would need a special charger, and the non rechargeables have an ultra long shelf life etc.

Lithium based non-rechargeables have roughly a 10 year shelf life. So if the choice is between them or alkaline, go with lithium. Higher quality brand name batteries will be less likely to fail and leak during long term storage. So if this is for an emergency lighting or radio type use, don't cheap out.

They're for a camera, so I don't want them to leak.

AA lithium should be good for at least 15 years (that's how the OEM dates them)

I have a Tekna-branded (probably made by Panasonic) CR123 cell that will be 30 years old next summer - came with my "Micro-Lith" in 1983.

I plan on load-testing it around Labor Day.

Didn't know up to 15 or so these days. Great for emergency LED flashlights.

What's a good source for these batteries?

At Amazon, it looks like most of the sellers with good prices are selling these as loose groups of batteries instead of in sealed packs

Is this too good to be true, and would these likely be old batteries?

ebay has been the cheapest for AA/AAA lithium, but expect to order in quantity (30+) to get the best price (around $1 each)

I would only buy from U.S. sellers to make sure you aren't getting Chinese counterfeits.
