  1. So I see several reviews complaining about these not lasting 10 years, these have a 10 year SHELF LIFE not a 10 year USE LIFE- those are 2 entirely different things. 10 year shelf life refers to how long these will be viable for sitting on a shelf/stored not plugged into anything. As far as actually putting these into something you can expect use-life to be about the same as a typical 9V or a little longer.I bought these to power the Fishman Fluence active pickups in my guitar because these types of batteries provide very consistent power – which is where these excel compared to your average alkaline 9V which can waver a little in power getting worse over time. The only issue with these is they will suddenly die out on you once they are done but they will give you the same consistent power until its last breathe.Who these are for:-People who have devices/uses that require very consistent power.-People using devices that are subjected to more extreme temperatures.-Expensive devices that could be destroyed by a small battery leak.-People who like to store up on back-up batteries for a long time for later use.Who these are NOT for:-People who think 10 year shelf-life is the same as 10 year use-life.-People looking for rechargeable batteries (these are NOT the same as rechargable lithium batteries)*NOTE: These are very close to the size of your average alkaline battery but ever so slightly bigger since the edges are not rounded so if you want to put these into something where the battery space is a very tight fit it might not fit.

  2. I bought eight of these to install in smoke detectors that were a year old. I figured it would be less expensive than swapping out alkaline every year and putting these in every five.Two days after I put them in, two detectors were chirping! Pulled the batteries, put in alkaline ones, chirping stopped. Of course it was at 2 AM.Tested the Tenergy ones, volts were low and load test, weak. I called, the fellow was pleasant and told me to write a email with all my info. I did. I got a response asking for more info. I gave that. Then another email telling me the batteries are fine and that it must be my detectors!The ad also claims the batteries are ‘date stamped’. Not true, mine have no date, no serial number, nothing.Such a shame as I bought these based on reputation,So if you buy them, know you are taking a gamble. I’m concerned that the ones still installed,. will they last? Should I of bought Duracell or Eveready Li batteries instead, from companies that are more customer responsive?I will probably end up returning these.

  3. Tried the generic, white label brand bc they were cheap as a 10 pack, but 4 batteries died in smoke detectors about a year after replacing them, within a few weeks of each other. Bought this for smoke detector on 20’ ceiling bc it was a hassle to replace… now it is the ONLY brand I use for this! Nobody likes having the low battery chirp on the smoke detector wake them up in the middle of the night. These definitely cost more but last for years which is worth it in my book!

  4. It was a perfect fit!

  5. The battery has a very long life span as the Meter shuts down operation after a few minutes of operation,good value of the money.

  6. I used these batteries for smoke alarms. Hope they last.

  7. good price

  8. Once again these batteries work and yes that’s all I require…

  9. I prefer lithium batteries, particularly for cold environments e.g. exterior door numerical keypads. As well, I swapped standard 9-volt batteries which come with smoke detectors for lithium batteries as I understand they last longer.

  10. Replaced smoke detector original batteries.

  11. Works well

  12. Hard to rate but since purchase no issues

  13. I have great praise of the battery

  14. I was very pleased to find these 10 year batteries available in an 8 pack as I have 11 smoke detectors in my home; it represented a huge cost savings, was also more convenient. My batteries were rapidly delivered and installed, good deal! I like that I shouldn’t have to deal with that again for ten years!

  15. Reasonable cost for hopefully a long lasting 9 volt battery. I am using it especially where the smoke detector is difficult to reach due to high ceilings.

  16. So far so good. They all seem to be working. Whether I get 10 years of life out of them remains to be seem. Great price.

  17. Great replacement for name brand at a way better price.

  18. I was able to get these on a black Friday special. When purchased at a discounted price they cannot be beat. At full price I’d prefer Ray-o-Vac or similar which gives compatible performance but sometimes there are deviations in size of the battery that can cause the off-brands to have alignment and fit issues in smoke detectors, etc.

  19. Last time I purchased was in Nov ‘21 from same seller. So it lives up. Used it for my baking scale.

  20. Best batteries for smoke alarm.

  21. Great long lasting

  22. Great price for lithium batteries!

  23. Hard to rate since they were recently installed in my smoke alarms. Many of my smoke alarms are very high up and a major pain to replace batteries in. If these really work 10 yrs., that will be great!!!

  24. Simple to use and longevity of battery!

  25. About half the price of a “name” brand but these work just as well as replacements every 6-8 years in our smoke detectors.

  26. Need these batteries for glass breaking sensors on Simply Safe system. Was buying at Home Depot but sometimes they are out of stock. I can order them from Amazon and get them next day. Good price for a pack of six!

  27. Long lasting

  28. One of our smoke/carbon monoxide detectors needed the battery changed. I decided to change them all and the cost of the batteries in the store are high. Turned to Amazon and found the batteries at a much cheaper price and they came packaged great and the expiration date on them were way out! Very pleased !

  29. works well

  30. These batteries work just as well as the ones you get in any big retail store but at a much better price!!

  31. Door locks. Good service and price. Thanks

  32. Last longer then most for the size and application. Saves me time and money

  33. I think the packaging was very secure and kept the batters free from premature draining. We’ll seehow long they last. Other 9 volts last about a years so hope these do as well if not better.

  34. I’m intrigued by lithium primary batteries, for devices where you change batteries yearly or even less often. There’s much less risk of a leaking battery damaging the device, than with an alkaline. (If you change the battery more often, you may want a rechargeable. But rechargeables have some self-discharge, so they don’t last as long in very-long-battery-life devices, like remote controls, or sporadically used tools.)I was intrigued enough to buy an Energizer Ultimate Lithium 9v when I saw it at my local drug store, even though it was over $20 USD for one, which is not economical. But there are a surprising number of devices where it just doesn’t quite fit! And it’s because it’s boxy, with sharp corners. Often 9v battery compartments have at least 1 slightly rounded edge, and the sharp edges of the Energizer means it’s pushed a half millimeter too far away from that edge, and it’s uncomfortably tight, and stressing/bulging plastic doors or clips etc.This product, the Tenergy 9v Lithium, is described as being slightly small so to fit better, and the edges look rounded. Also it’s much more reasonably priced. So how is it? It’s better! Still a slightly tight fit in some devices, but significantly better. I got out a digital caliper to try to confirm the cause. The LxWxH of this Tenergy is actually not smaller than the Energizer Lithium, it’s 0.1 to 0.2 mm larger, but so is a energizer Alkaline. But the max diagonal length, as suspected, is 0.7 mm less on the Tenergy than the Energizer Lithium, because of those rounded edges. An energizer alkaline is another 0.7 mm less diagonal than the Tenergy, I guess alkaline is even more rounded still.Both of the Tenergy Lithium batteries I received provide 9.5V with a 17 mA current draw (9.7V unloaded). So far looking great, long term we’ll have to see. For the better fit and better price, I really like these.

    Energizer batteries have the longest shelf life of any battery. Duracell is crap (shortest life) in comparison.

  36. So far they are perfect.

  37. Work great and a good vaule.

  38. Batteries are of higher quality and half the price of name brands. I’ll never purchase the name brands again!

  39. I purchased this package of 9-volt batteries for my smoke detectors. I had originally purchased the alkaline version, but they didn’t have enough voltage to keep the detectors from continuing to chirp. I purchased these and everything is quiet on the home front.

  40. These Batteries have lots of Power, great Quality, High Performance and small packaging for easy storage. With long Battery life makes for Good value for the money.

  41. great long lasting batteries

  42. Long life reduces battery changing

  43. needed a long life battery for the smoke alarms, and this was it! Pricey otherwise…
