I live in a remote mountain area where brief electricity outages of just
a few seconds occur several times a week. Resetting the clocks on small
appliances (microwave, coffee maker, answering machine, etc) has become
an all but useless task. Does anyone know of a very small battery
backup or UPS of some sort that would be suitable for this application?
I don't need enough power to run the appliance, multiple
outlets, or anything like that . . . I just want to keep the power from
being interrupted so I won't have to reset everything every time the
electricity goes out for a second.
TIA for any information anyone might be able to provide.
Won't support a microwave oven, maybe not coffee maker
either. It has always annoyed me that the manufacturers
won't invest a little more in power-dip ridethru for
digital clocks. I suppose it wouldn't be a selling
Sure it would. But the big box mart tells people the only thing that is
important is price.
We have a digital alarm clock radio in the bedroom that had a small
compartment in the bottom for a backup battery. If the power dropped off
the display blanked but the battery kept the RTC running. I tried to
find a new one with the same feature and they just don't exist.
I have a Sony clock radio that I purchased recently that not only keeps
the time when the power is out but I believe it also automagically
adjusts for Daylight Savings Time. It wasn't that expensive. I
don't have it with me right now so I don't have the model but it
is currently in production.
It would for me. A couple of my clocks have 9v backup in theory, but the
'low batt' light comes on in a month. At 4 bucks a shot, I'm not
inclined to replace them that often, since the whole clock only costs
15. I'm fine with blanking the display, just store the time and alarm
setting- that doesn't take much juice.
I have one of those WWV-fed 'atomic clocks' that also eats batteries,
and you have to force-reset it 2-3 times whenever you change battery,
before it gets back in synch.
Does anybody really know what time it is?
A backup battery should last a few years (unless you have a lot of
power outages, of have one that uses the battery for an alarm).
I have several clocks with backup batteries. They usually run fast
when on battery (for example: clock set right before 1-hour power
outage at 2:00, when power comes on clock shows 3:24 instead of 3:00).
However, the problem isn't too bad during an outage of just a few
BTW, at least Daylight Saving Time is good for SOMETHING, an
opportunity to correct those clock drifts.
The biggest problem here is equipment I want on but it suffers from
"power amnesia". Most TVs and many other devices with electronic
controls have this problem.
I think these things use a cheap RC network to replace the 60hz
timebase when the power is off. I guess they err on the "safe" side
when they choose the "C". Nobody got in trouble for being to work
I used to have several outages like that a week, it was a loose
conection where power came to the house. For only a few seconds a
week, maybe wind is affecting cables that need attention. The power co
checks this stuff for free, call them and have them figure exactly
what is the cause. You probably dont need to buy anything to get good
She did mention it was a remote mountain area. Likely the area is fitted
with automatic reclosing breakers so the brief dips were likely the
branch that blew across the line or the now toasted squirrel. Previously
I'll bet it was a few hour wait for the utility to drive over, find the
issue and change a fuse.
Mountain area or not, a few seconds every week is likely something
loose and easy to fix. She should simply ask a neighbor if they have
the same issue. My issue was a temporary clamp that became permanent
and was loose, it could even be inside her home in the main panel.
I have the same problem. I bought battery operated wall clocks and no longer
reset any of the electronic clocks.
For important stuff like my computer, I bought a UPS at an office supply
store - the largest capacity they have.
I suppose for your phone, you could do the same, except would only need the
You could use a multi-handset cordless phone. Then you can have a
phone in every room but need just one UPS.
BTW, there are some cordless phones that also connect to a cell phone
(using Bluetooth), so you can have the multi-handset advantage with it
too. I know of both Uniden and AT&T brands.
