Still not clear about batteries. If it is powered by 12 VDC source, is the internal battery needed or not?

Yes. Two small battery AAA only to keep the programs memory when it is not connected 12 VDC.
1540730
Batteries to keep program when controller is disconnected from 12volt power otherwise you need to program again

I believe the internal battery runs for about a year, but gets charged from the 12 volt source.

It's powered by the car/trailer 12 volt battery. I don't remember installing batteries in mine (but I'm old and suffer from "CRS"). If it has batteries they are simply to retain memory of clock/day and if you programmed start start and stop cycles.

I believe it is needed, I put one in when started using it daily for 3 months still going even in extreme cold.

i hesitated a bit after seeing reginald goodman's answer. mine was powered with the USB for the conversion operation (so is the much bigger one i bought elsewhere. batteries are not necessary), but i THINK i remember seeing a battery compartment because you can carry this thing around with you and the batteries may become necessary then.

It says it requires a 12V battery as well. Can it be powered by the 12V battery, or is that just to store configuration, etc?

Require power source of 12v DC. Could run on a 12v rechargeable battery pack not sure how long depends on battery pack.

Correct! you can hook up directly to a 12volt battery. It also(mine did)comes with a lighter plug as an extra option but i never use that...I just run it off of marine type batteries which i recharge when needed.

The internal battery pack is rated at 2000mAh at 22.2V internal voltage. The voltage at the "12V" plug will be closer to 14V though. The 44.4 Watt-hour rating is more useful in this case.

The power supply is an option. It uses a 9 volt battery (not supplied - no surprise there). When the power supply is used, the battery functions as a back-up.

It definitely is powered by a battery but I do not recall if it came with one. I seem to think it requires a 9v. Sorry that I could not be sure.

The one that I bought does both 6V and 12V batteries. I thought that I bought the 1500A. Wish that I could be of more assistance.

Yes, you will need a 12 volt rechargeable battery & 12 volt to 120 volt VAC inverter. Works great! we love ours!

The 12V source can be either AC or DC. Internally the Elitech uses a rectifier to convert an AC source to DC. If a DC source is applied the rectifier essentially doesn't do anything. While the Elitech says 12AC, I've been using it with a 12DC source for several months now.

No. it has no internal batteries. you have to buy an external 12v dc adapter

It needs 12 volts battery. Inverter needs air flow inside Battery Cables cannot be too long to attach to inverter no more than 4 to 6 feet of battery cables. batteries will need to be recharged. How many watts are going to use from the inverter. It only gives about 2/3 of its 1500 watts. Researched everyone that is using for emergency was using a running car or some sort way of regeneration to batteries.

This unit will definitely provide 24 VDC from a 12 VDC input. I have used several in an application where we needed a 24 VDC supply off of a 12 VDC heavy equipment battery pack. However, charging a battery is typically a more complicated issue - amperage load and not over-charging etc. So you should be good for 24 VDC but I do not know enough in regard to battery charging to say yes or no

12 vdc is required, if you lose power the configurations stays, i recommend you to use 3rd party relay on the output and do not use the direct relay output

There is no internal battery option. Household AC or external DC (12V) or AC power converter pushing 1 A.

No you have to use the power adapter supplied. Unless you rigged up a 12 volt DC battery near it.
