Yes this will work, BUT you would need a 12v DC power supply to run the timer.

You plug it in a normal outlet. You can only have timer go to Constant on, 1, 2, 4, 8 hrs.

I wired mine clock/timer controlled by DC - switch side DC. It works that way as well.

According to the APC spec sheet, the timer is battery-powered (it does not say what the battery type is).

There is internal battery( non rechargeable) just to keep the clock going, but to control you need 12+ volts to be able to function. I guess the internal batt is replaceable.if it stays plugged to power source will go without the batt. It worked fine for me, not a bad purchase.

I don't remember-it is in the instructions. I did change them and it worked for a while and then stopped working. I changed them again and it still didn't work. I, therefore, tossed it and bought an electric one the plugs in and put it on a timer. I "think" the solar panal on top unscrews and the batteries are there.

Since I gave it as a gift, I had to contact another person. The timer takes one AAA battery. Have a super day!

It just plugs into a standard outlet. You cannot program it for anything other than the times shown. It is a simple button push to move from onesetting to the next. It is not a repeating timer either. It completely shuts off when it times out.

I haven't had it long enough to replace the batteries. Generally, most electronic equipment holds information such as date / time for short periods when bateries are removed. If not, is easily reset through the menu sequence. Sorry unsble to be of more help. Tony

It is just a timer. Whatever you can plug into a power outlet you can plug into this and it will power it according to settings you chose on the dial.

It turns on the battery. But don't buy this it is a piece of junk. May work for one day.

Without power the timer doesn't work. You would have to reset it like a clock.

It requires a constant 12v but only draws current to run the timer, which is minimal. I don't guess I understand the question. I don't know how it could be hooked up without a constant power supply. The timer is hooked in-line between te battery and the item needing to be turned on and off. I use it to control a solar heater. It comes on and turns off at a predetermined time.

I haven't used a timer. I don't think that it would very effective if you could figure out how to hook one up. The on-off button has to be physically pushed. Also, the batteries don't last long before a new recharge is necessary.

battery timers need a potted dc latching solenoid. the valve will work, but you need the correct solenoid which can be bought seperately
