How long should they last powering a smoke detector? Mine don't seem to last more than 2 years.

Asked by Ed April 17, 2018

Answers

Our smoke detectors are a/c wired and the batteries are backup. Ours lasted exactly 3 years to the month before needed to be replaced.

Can this battery be used in a smoke detector?

Asked by horticultor51 February 22, 2017

Answers

Yes, lithium batteries can be used in smoke (and carbon monoxide) detectors... but be warned. According to Consumer Report, when lithium batteries die, they do so with little warning. The smoke detector will not chirp for very long as the battery nears the point of needing replacement. This is because lithium batteries hold their voltage higher for a longer period of time over their life. The voltage then drops quickly once their life wears out. This is different than with alkaline (and other) batteries, which more gradually decrease their voltage as they wear out. The smoke detector warns you of a low battery by starting to chirp when it detects the voltage starting to get low, and it does this for quite a while when alkaline batteries are used (days or weeks). But when a lithium battery is used, you may not be home when the smoke detector starts chirping (maybe you're away on vacation) and by time you get home it has stopped chirping because the battery voltage is now even too low to chirp. In which case, you have no smoke detector and you don't know it, putting you at risk. Bottom line is, if you use a lithium, you must remember to test your smoke detector more frequently and especially when you come home from being away for a few days. This risk is even greater for smoke detectors installed in rooms that are far away, where you may not hear the chirp for a while until you are in that part of the house (say, in a garage or basement that you may not frequently go into). Be safe.

What is the difference between Energizer Advanced Lithium and Ultimate Lithium 9 volt batteries?

Asked by mike March 21, 2016

Answers

The 9 was inside a styrofoam faucet cover with a maroon plastic outer cover (also bought at Home Depot) so it may have stayed warmer than the exposed AA. It powered a once-per-second beeper beacon that was still beeping annoyingly loud when the payload was recovered about 4 hours later. No voltage readings were taken on the 9v.....but that sounds like a good idea for another experiment on the next flight! Hope Depot or Energizer, if your are interested in some batteries or other products being tested in the conditions of near space, I know an 11-year-old that would be glad to do it.

Is this a 2-pack like the description or a single battery like the picture?

Asked by Joe February 7, 2016

Answers

This is a 2-pack, which the picture shows for me. HD also sells them singly.

Excuse me dimensions of this battery please?

Asked by Kiril December 11, 2018
4
Answers

They are the exact same dimensions of any 9V battery. All AAA, AA, and 9V including C and D sizes are all the same across all manufacturers product lines. The dimensions of this battery will match any and all other 9V batteries on the market and it will fit in any device for which a 9V battery is specified.

freebie?

No, I paid for it. Wait, are freebies available!!!

I just purchased L522B batteries for my BRK smoke and CO alarms. They were unique as the case ha...

Asked by Jack March 2, 2018

Answers

Yes I have had the same problem as they are a bit hard to get into the BRK smoke detectors but you can push it in a bit harder and they go in. Just use a bit of force and they will fit.

Works as expected
Customer review from Energizer Brands logo
[This review was collected as part of a promotion.] No surprises with this battery. Needed this size for one of my kid’s toys and I expect the battery will outlast the toy. I appreciate I could get just one and didn’t have to buy a giant pack since this isn’t a typical size.

Great Product
Customer review from Energizer Brands logo
[This review was collected as part of a promotion.] I received my Energizer Ultimate Lithium 9V Battery just as my smoke detector started beeping needing a new battery, perfect timing. Or so I thought, though my smoke detector takes a 9V battery, the new Energizer battery did not fit my smoke detector, I was not aware that 9V batteries came in different sizes. I have purchased other Energizer batteries and they work great, so I know when I eventually find something that this battery fits in it will work just as great. Once I start unpacking my Christmas decorations, I have a couple of items that require 9V batteries. Can’t wait to put it to good use. Though I was not able to use the Energizer Ultimate Lithium 9V Battery for what I intended, I do highly recommend them, Energizer batteries are great batteries.

Great battery
Customer review from Energizer Brands logo
[This review was collected as part of a promotion.] I got this battery, and am using it in my smoke detector. I'm expecting the battery to last a while. As always, every six month a check will be conducted. It does have sharp squared shape to it unlike the others that are rounded of. It still worked and fits great.

Energizer Ultimate Lithium 9V battery
Customer review from Energizer Brands logo
[This review was collected as part of a promotion.] I was very excited to receive my 9V battery. It was packaged very similar to any other 9V you would get. My purpose for this battery is to put it in the control unit of my water softener. It is important that this battery stay strong for a very long time to hold the data for the water system. I have currently had it in my system for almost 2 weeks and it is going strong. I have always been an energizer supporter and this one continues to prove my loyalty. Go get you this battery and put it in your electronic that you rely on.

Great 9 volt battery
Customer review from Energizer Brands logo
[This review was collected as part of a promotion.] I needed a 9 volt battery for my smoke alarm and I chose Energizer. Such a trusted brand and I like that it is a lithium battery and will last for years. I also like that it has a 10 year shelf life so I can purchase a backup battery for when my smoke alarm needs a new one. The safety of my family is my priority and having an Energizer battery is the only brand that I will buy.

Thanks to the dependable, long-lasting Energizer Ultimate Lithium 9V batteries that power most of these safety devices, I sleep really well at night knowing that my family is effectively protected from harm!!

Best battery for the safety of my home!
Customer review from Energizer Brands logo
[This review was collected as part of a promotion.] I have chosen to use this 9V Energizer Ultimate Lithium battery to replace a smoke detector battery in my house. I work at a fire department, and there are an incredible amount of people who don’t change their smoke detector batteries until they start chirping; I try to take a proactive approach to safety. This battery has a 10 year shelf life, so I am assured that this brand of battery will keep my smoke detectors operable and protect my family at the same time. Remember to change your smoke detector batteries!
