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.
