is this really good for smoke detector??? I bought 8 of them and use MaximalPower FC999, and it doesn't hold the charge...

I wouldn't use them for smoke detectors as the charge only last for a few weeks. I bought them to use in cordless microphones, and they work fine in that capacity.

Yes and No. These Tenergy Centura seem to hold a charge for along time, UNLESS the battery is in a warm/hot area (as in the attic for which I'd use a conventional battery). The problem is how is the battery connected to the smoke detector? If it's a push in and pull out its okay, if you have to clip on the connector you might break the terminal on the battery when you need to recharge it. I'd perform a monthly test on the smoke detector, but don't go past 12 months without recharging. I've found the MaximalPower needs to be rebranded as "MinimalPower" and totally worthless.

I'm very satisfied with mine, I use them on a high drain device and it last a long time. A smoke detector should be a low drain service . Make sure you are charging then properly, my charger is over 10 yrs old and it takes many hours to re these but it does the job. Maybe you have a bad battery, or charger . Try also and see if they work on some other device.

That is precisely why I bought these batteries. They work very well, just make sure your smoke detector has a low battery alarm. The smoke detector in my basement started beeping after 4 months. the smoke detector in my living room started beeping (alerting me of a low battery charge) after 8-10 months. The batteries work great, but you have to make sure you have a way to testing the alarm every month or so. I test my alarm every end of the month on the weekend. That way I do not forget. These batteries have saved me some pretty penny so far. I hope my comments help you. tks vm BG

Worked only a couple weeks per charge in my smoke alarm,what I bought them for.So YMMV,didnt work for me.But these did...EBL® 840 9V Battery Charger with 4 Pack 600mAh Li-ion Rechargeable 9 Volt Batteries

YES!! This assumes your smoke detector takes a 9 volt battery of course. That is why I purchased this product. As far as I know, all batteries have a sell by date, but I can't tell you specifically how the ones you will get will be marked.Hope this helped.

It sure can, it comes with a regular key. The batteries in mine lasted more than a year too. I think if you change them when ever you change the batteries in your smoke detector, you'll be ok. So far I've had mine more than 3 years, and only changed the batteries twice. Plus it gives you a warning when the voltage starts to get low.

I answered this several weeks ago, and I just checked the site and for some reason Amazon didn't post it; their bad! All of my smoke alarms were hard wired as per code. But if the 9v back up battery in one died, all of the alarms went off; I was up all night one night. Anyway, my old ones were not Kidde, but the Kidde replacements fit perfectly.Go to: www.kidde.com and find their Customer Support 800 #. They were very helpful when I called them. Good luck, and I am sorry my first answer was not posted; I have no idea what happened. navydoc

Yes, the small indicator light always blinks unless you remove the batteries. But that is really no different than most smoke detectors. It hasn't drained our batteries and isn't annoying us. The lantern works really well.I highly recommend it.

If it chirps every 30-40 seconds, the battery may need replacement. I can't recall if there is any "expiry" date on the detector - is it exactly 1 minute? I suggest tossing in fresh batteries and maybe clean by vacuuming around the detector with a brush attachment. And see if that stops the beeping? I thankfully have not had the chirping problem until after about a year and it was because the battery was weak. Is it all of them beeping at once? I would hardly think all 4 could fail at the same time, but try the obvious approach first. Otherwise, you may have defective detectors or your wiring may be faulty.

The thing doesn't work.......don't waste your money. We had trouble trying to make the thing work, sent e-mails, left messages (for the supplier) and never received a response. If you're gonna spend the money, get one from your local security provider (with monitoring). By adding the smoke detectors, some insurance companies offer a discount that helps out on the monitoring fee. You're money ahead that way in the long run. And.......you have 24/7 monitoring as well.

No, it will only silence that one alarm. If the smoke has not cleared in 4 minutes, it will sound again. It will also silence the low battery beep for 24 hours. (If your batteries happen to be low).Why are you finding alarms with missing batteries?

I have had 2 of these in my home for over a year and I have never had a false alarm. I run the test about once a month and other than that I have never heard them. Sorry folks, you have either received bad units or you have dust or other particulates causing your problems. I am using the 120v version.

They should last a long time as the unit is direct wired to 110 volts. So it's based on the shelf life of the battery. I have several direct wired smoke detectors and I only replace the batteries when one of them is low, then I replace all of them. batteries. I expect the batteries will last over 2 years.

Call Universal Security Instruments customer service. My home is hardwired and I wanted to ensure all 5 detectors were connected to the household current and have the battery as a backup. Further, all of my detectors are interconnected so that if one goes off, they all go off. You may want to check out a different model if you are only interested in a battery operated detector.

you can replace it with any smoke alarm that supports your connection, these are great smoke alarms and I stayed with the 1276 units, they are easier to change the batteries in,and they have a great track record.. but its your call any smoke alarm is better than none..hope this helps.

I'm not a "science" guy - just a homeowner who's had CO detectors for years. Mine are up high just where a smoke detector would be. Many friends and "experts" have seen them up there in my house. Nobody ever said it was not the correct location.

I used these batteries in smoke detector. Within a week two of the smoke detectors started beeping due to low battery. It has never happend before. I did end up buying new batteries.Sellers were not helpful. I will have to pay return shipping charges, and they were not sure about refund.I will not buy batteries from this seller again.

Hello Sunni,I have been using them in my smoke detectors with no problems, change them once a year. Don't know if your particular model calls for these, but I don't see why not!

Hi Kevin, 8hrs on a full charge of continuous recording mode. Up to 30days on Stand by mode. We do have other option IR smoke detectors that is 20hrs on our spysonic website as well if the 8hrs is not enough time for you.Thank You.

Bought a contractor's pack (6 batteries) for use in smoke detectors. Since we did that in the spring of 2013, I have no way of knowing how long they will last. We found out about these 10 years lithium batteries from the local fire department. That's what they recommended so the batteries didn't have to be replaced every 6 months or once a year
