What specific battery does this timer take?
845765
It uses a 357/303 button battery. (I can't tell you the voltage off hand.) It comes supplied with one and they last quite a few years.

I have two of these timers, and the battery numbers are quite different! They are however small, cheap, long lasting and easily replaceable at any Radio Shack or similar stores for "peanuts". (The info on the newer one's battery is CNB G13A. )

My little button battery says: G13-A CNB + MICRO CELL.Also, it's true it's not extremely loud, BUT it does go on and on, and I do hear it even when another room. And it's hard to find a reliable one that's easy to use and can time FOUR things at the same time. I really like it.

It takes a G-13 A (CNB+). Personally, if I were you.... I would not buy this timer. You can barely hear it.

My spare batteries are all CR2032.. the device is about 2 months old.. works fine.. the transmitter apparently uses a different battery (12 volt). The device works well.. just be sure to hold down button for couple of seconds to give it a chance to set up the frequency and get a response.

You almost certainly have a bad battery. I own several of these timers, and the batteries last for many months even with heavy usage of the various features. I believe the clock mode is running in the background all the time and you cannot turn that off.

No, there isn't. That was the one thing I did not like about this timer. However, I have had it for many months now and used it a lot. The original battery is going strong, so I now consider it a non-issue. If I only need to replace the battery once or twice a year, no big deal.

I used a 12v battery ( which is charged from a solar panel,) to power the timer and the led strip lights. Works perfectly. Lights run 4 hours a day, timer is always drawing a small amount of power from the battery.

Don't really know. I would think that it would work fine on any timer. I just plug it in when needed and pull the plug out after.

You have to remove the batteries. Most of these timers seem to require that.

It's been a while since I bought this feeder, so I don't know about the battery backup timer. But, yes, it is controlled solely by an external timer. I am using the timer they bundled with the feeder and it works fine. Also the feeder is excellent.

Not 100% sure, but from my experience this is just a 24 hour timer-not programmable the way you require- I recommend a different one for that function.

I don't know. Just run a search on your camera and it'll say what battery it takes.

There us a battery inside under the on-off circle. It takes a flat CT2032 or so size like that!

Sorry to say I don't know. I returned it and got a blue moon timer that suited me better. Barbara

Hi! Only replace your timer with the same model/serial number that you actually have. I'm not a pro, I don't know which other could work as the one you own,but you must keep the same model! and yeah... you could vary the serial, it will work, but with some deficiencies! Better safe than sorry, match model/serial for accurate replacement. Good luck!

Yes there is a battery that recharges itself and never needs to be replaced. I believe it will hold your settings for 30 days. It is a marvelous timer/switch and I highly reccomend it.Earl Tillman

I don't know - it was a watch type battery. I threw the whole thing in the garbage after a month.

Hi Bruce, A Small Watch Battery, Not Sure Of The Number, I Have Checked Google And Can't Find The Battery That The Clock Uses, Sorry Neal

I would not recommend this timer to replace any device. It is very unreliable.
