What's the difference between AE-23 and A23?

As far as I can tell and I'm no expert, but there is no difference between the AE-23 12 volt battery and the A23 12 Volt battery. The popular brand companies use the A23 designator and off brand companies use the AE23 designator. Hope this helps

Nothing on the Amazon page or image says it's alkaline. Where does it indicate that it's alkaline?

if you llok close up on the battery its says alkaline on it. you may not see it in this picture, but if you look at other A 23 energizer picture you will see it.

what's the difference between the 23a and 27a batteries?

Google this " List_of_battery_sizes " (where I got answer). The A23 is 2/100 of longer" and 9/100" wider. So a 27a should fit where a 23a does fits in most cases, but not necessary the other way round. Both are 12V DC so no harm to a device if either battery fits and works in your device.

Reliable brand

These are for my doorbell bellpush. The last one lasted a year (and yes; we do have visitors!) so these two will last me a while. I've never been disappointed with Energizer batteries and these didn't break the bank.

Short shelf life

Battery pack was delivered quickly and the product is working fine. I only needed one, but bought a pack of two so I had a spare for replacement.However, I couldn't see a use by date on the packet - and only found one by peeling back a label somebody had slyly applied on the back,which revealed October 2025. That's only a little over a year, and the dead battery I replaced lasted more than five years...go figure. This must be old stock.
