Can the CR1220 battery work as a backup battery for RTC when 3.3V input is off? How long does the battery last with the 20mA consumption?

Hi Gustavo, A typical CR1220 battery holds approximately 40mAh. The GPS should last approximately 90-120 minutes on the battery alone. If you have any additional questions, please feel free to contact us. Thanks again!

the battery is for backup only..... in case electricity goes out. You still need to wire it.

I just contacted Carl Manufacturing. They told me it's the same as RT-200. Their customer service is pretty good!

Wasn't aware of this [requiring a non-std batt] - mine works fine with a 12 volt deep cycle from wally-world. There are other issues with this model (brand?); connections and side-scanning limitations.

Batteries are needing to be replaced after about a year for any remote. CR2032 battery is used. You could buy batteries on Ebay for very cheap prices. Batteries are consumable. They dont last forever.

Comes with a CR2025 3v battery. Great value. Works perfectly. Even under heavy use I doubt you would ever need to change it .

Hi Rosalyn, To keep accurate time, this unit contains a CR2032 battery inside of the unit as a backup power source. The battery keeps the clock operating in the event of a power interruption. Which means that it will not run for a long time if the unit uses battery alone. -Ely

Yes Jonathan, if you've been experiencing your RTC,real time clock on your laptop losing time; and if you have to reset it alot this could be the culprit. Usually they only last about five years or so and then they have to be replaced. You may have also experienced not being able to get Windows updates or other updates for programs that use the current correct time as a guide to give you the proper updates for all your favorite programs that you use. But yes this CMOS battery should fix your problem, I have a DV6000 pavillion myself,the first one I got was a dud, but they sent me a replacement for free and it's worked great eversince. Hope this helped you out Johnnathan. -Pat- Yes Jonathan, if you've been experiencing your RTC,real time clock on your laptop losing time; and if you have to reset it alot this could be the culprit.

HiNo, it doesn't have battery backup system, I think you can use a battery convertor to convert 12v DC to 110 AC, I have such a device and haven't try it yet, will try this weekend.

I honesdtly don't know, I checked a couple of sites and they don't specify what battery is required for the RT-Shield. If you al;ready have one, why not take out the batery/batteries and see what is in there.

The battery is a CR2032, 3v; about the size of a quarter. Should last very long since "on" time is quite short; depending on usage however.

I used this in a UPS (uninterruptible power supply) for a computer. They battery is rarely activated, and the last one I got lasted over 5 years. I would check the VA and make sure its compatible with the equipment you are planning to use it with.

Gee I bought it awhile ago now and it plugs into an outlet, but I checked the description on Amazon and it doesn't say there's a backup battery. There is a little red light though, so if it were to turn off, you'd know it is not working.

The battery is a backup in case of power interruption. From a practical viewpoint you need a low voltage power supply.

Yes, the CR 2016 3V spec is the same for virtually every brand name. Certainly for Energizer, Panasonic, Duracell, EverReady, and Radio Shack to name a few off the top of my head.Edit: The only time it *might* not be the same is for a generic or off-name brand. I don't generally trust those in my devices anyway due to the fact they don't always follow standard specs like the major brands.

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 don't know the answer as it is my main battery for my laptop. I just use it till it runs out of power and then plug the power cord back into the 'puter. It's still good for 3 hours continuous use. When I bought this battery, also upgraded the memory and it was a cheap solution to buying a whole new laptop
