Have researched some w/battery backup that only save settings....not current time. Will this keep current time with a 3-hr or less power outage? Thx.

Hi, As per the user instructions, "This unit contains a built-in, non-replaceable, rechargeable battery to maintain the date and time of day information for at least 4 consecutive days of AC power interruption. The other settings are maintained indefinitely without AC power." Hope this helps.

Sorry, I can't Answer. I don't believe we have lost power since this has been installed. I know that it works consistently and comes on at the same time unless we reset the time.

I returned mine due to defects and bought from Leviton. The internal battery gets constantly charged. It costs twice as much but I can also program it to come on at sunset and it automatically switches to daylight savings time

not sure but with the cold winter it did hold the correct time in my garage even though it was very cold and said on occasion low battery

I have not tested it for that length of time without power but I would think that it would. The unit uses very little power to run the time circuit and LED display.

honestly I don't know since I have not experience an blackout in my area after installing this timer switch. However, I strongly believe that the battery backup shall keep the time for one simple reason, the time is part of the setting. I hope this helps.

There isn't a plce to put a battery. when I unplug it the power goes off, but when I plug it in the date/time info is correct without resetting. I don't use it as an alarm clock though.

Yes, it does have a battery backup. It works great, as i've turned the circuit off several times during our remodel and no power loss to the timer. All the times and programs remain correct.

Yes, the clock and all other settings (i.e., zone watering times) are retained during a power failure. No battery is needed, everything is stored in non-volatile memory:Quoting from the RainBird SST user manual:◾No need to reprogram after a power outage. All timer settings are stored indefinitely in memory. No backup battery needed!

okay, I was assuming the display would go blank after 5 mins. to save battery but I guess it always stays on and shows the time.thanks

It stores the settings in non-volatile memory, which is not lost if the power goes out. So it doesn't need a battery backup.

It does *not* have a battery backup. Some settings survive a power outage, but some do not. For example, the setting to *not* go into power saving mode is not preserved; the "standby" mode - you have to reset the "standby" power level whenever the power comes back on - to disable that feature is you set the "standby" power level to 0 (zero) watts. The option to turn off the PIR motion detection feature does keep its setting when the power is restored. I don't know what happens to other settings that I do not change from their default values.

It depends on the draw. If it's a computer at rest or hibernating, you might get 30 min. Less power draw, more time.You can set it to shut down the computer at a percentage of remaining battery power. I have mine set to 20% remaining. You have to download software from Tripp Lite to enable this feature, but it protects from hard shutdown. If it's a spike or a short power loss, the computer won't even notice and won't shut down. Great system. I have my satellite box (no reboot) and my phone answering machineplugged in.DO NOT!!! plug in a laser printer!!!

Location is saved, but you will have to enter date and time each time you turn on the power. Not a big deal only takes a few seconds to enter.

You don't have to reset the settings. If the power outage was short, you don't have to reset the time. If the power outage was for an hour or more, you will have to reset to the correct time in order for it to work properly.

If you unplug, timer has a rechargable back up battery inside incase power out or disconnected by accident, to save the same setting.

Dear Florida, I looked through the owner's manual, and I can find no reference to a backup battery. I have experienced several power outtages, and all settings including time and date were preserved each time. Willy seems to have had a different experience with losing time and date, so you're left to figure out which one answers your question. Have you called/written Rainbird? That would give you your most authoritative rather than anecdotal answer. I've had nothing but good performance from my unit which I've had for nearly 3 years. The manual one-zone-at-a-time limitation has not been an issue for me, but I can understand it could be annoying for some.

I have changed my battery many times without any data loss. I have two batteries which I sometime have to change in the middle of a recording and only looses the time from satellite disconnect to reconnect.

The time displays all the time when the clock is plugged in (either by USB or power adaptor). I don't think it can be set to keep the display on indefinitely if you are using just batteries. But since there seem to be two different versions of this clock being sent out, it's possible the model I didn't get has a way to do so.

Below is what the tech specs say about loss of power. There is no replaceable battery that I see. I suspect it the local time is saved via a capacitor type back up and the other settings are stored permananetly any time you set them. I have only reset mine once and that was because I wanted the light to come on later because of holiday deco's on the porch.Power outage: The screen is blank. Only the time must be set if the outage lasts more than 4 hours; all other settings and programs are permanently saved.

Yes, This is a simple 24 hour clock timer. I wouldn't bother for short power interruptions but for long outages you should check time every once and awhile. You also need to adjust for daylight savings time twice a year.

Yes, there is built in backup. I don't know how long it will last, but definitely long enough for the typical power outage. Mine has been unplugged for over a day now and the display is still working (unlike the timer itself, which is permanently off, and ready for recyling).
