  1. Having just received the batteries, I am unable to speak to longevity. The packages arrived in blister packs within the bulk boxes. Some reviews say the size is larger that a typical nine volt battery and disallows placement in some devices. Though they are marginally larger than non lithium 9 volts, there was no difficulty with insertion into smoke detectors, a clock radio, and a multi-meter.

  2. These are outrageously expensive compared to an ordinary 9V battery. However, I gladly pay for these to use in my smoke detectors.Even living in a small condo, I have a total of eight detectors between CO and smoke detectors. All are hard-wired but with a battery backup. Every couple of months, one would get a low battery, and start chirping in the middle of the night. It’s always the middle of the night.I finally got irritated and bought a bunch of these. They claim a 10-year lifespan; I presume that is shelf life. With a small bit of electricity used as a backup power source in these detectors, I’m getting about a 4-5 year run before they start to chirp. (My advice: when one starts to chirp, rather than trying to track down which it is, replace all of them together. They’re going to start to fail at roughly the same time so you’re in for a month or two of random sleepless nights. It’s a weird luxury of sorts to only have to deal with this problem twice a decade, and is absolutely worth the money.)There is one catch — regular 9V batteries have slightly rounded corners, but these do not. This makes them a very tight fit into some of my smoke detectors. You might want to buy something like this 2-pack and test-fit them everywhere before buying a bulk lot of them.

  3. 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.

  4. I got two of these batteries for the electronic combination lock on a safe. Now, to remove and replace the batteries in the lock mechanism is a real pain in the neck, so you don’t want to do it often. Lithium batteries last a lot longer than alkaline batteries; also, these batteries have been found to put out a true 9-volts, not 8.5 like the Everyready Energizer 9-volts. Lithium batteries are lighter than alkalines and withstand extreme cold much better. There is one caveat: when lithium batteries go, they go with no warning, unlike the noticeable decrease in performance in an alkaline battery. So replace lithium batteries on a schedule. I will leave the lithium batteries in my safe for 5 years; I will replace them after that. These should power devices like a smoke detector for 3 – 4 years–but don’t wait for a low-battery indicator, because you might not get one. Lithiums provide full power until the end of their life, unlike alkalines, which will slowly decrease in performance. So if you use these in a smoke detector, replace at a set interval. You won’t have to replace lithiums in a smoke detector every year. So, if you have a smoke detector in an out-of-the-way place, lithiums are a good choice. I would change the lithiums every four years in a smoke detector; it’s just not worth it to “push your luck” for such a device. If the batteries die in my electronic combination lock, no problem–I just have to replace them. Just make sure you have a fixed schedule for replacing the lithium batteries in any device–and you’ll save a lot of hassle changing batteries frequently.

  5. I use Energizer Ultimate Lithium batteries whenever possible as they are the best battery around. None can compare. Plus these are unlikely to leak acid like other batteries do.

  6. I mark all batteries with their installation date. These “ultimate” lithium batteries provide 10-20% more life than common lithium batteries. They also have extreme shelf life; some technical documents claim 15 years. They are an amazing option if you can optimize their application.

  7. 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.

  8. 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!

  9. I use them in my temperature sensor everyday and they last for weeks or months at a time

  10. 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.

  11. It worked

  12. Didn’t have any problems with this order/item.

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

  14. I’ve used lithium 9V batteries in the past and this one seems to be on par with the others.The problem I have is these batteries have a 10 year shelf life. That is, if you get decently new stock. While I understand some months can pass between production and sale, causing this 10 year number to go down a little, going down to 7 years and 8 months is ridiculous.I received a battery that has a date of 1/2031 on it. It is now mid April 2023. When your inventory is getting old Amazon, discount the price and move them out instead of shipping people over 2 year old batteries and making them pay full price.

  15. Lithium 9v are expensive, but when they last 6x longer in my transmitters, they become economical and I don’t risk having them deplete in the middle of one of my shows.I use them regularly in 2 places – Wireless mics with high power, and smoke detectors because the battery probably will outlast the rating of the detector – just remember to change the smoke detector every 10 years!

  16. These lasted 1 and a half years in my smoke detectors. They still started chirping at 2am but at least I only have to hear it ever 1 and a half years

  17. Replaced smoke detector original batteries.

  18. I use these lithium 9volts for biometric gun safes and any of the few remaining devices in this world that still need to migrate to a USB-charged integrated battery. They last years of opening and closing and are much more reasonable in pricing. In my last house, we used this Lithium battery for smoke detectors. Easy choice for a long life 9v.

  19. Loved the batteries. Worked as intended.

  20. Works well

  21. I’ve had a 9V Lithium battery in one of my telescope’s components, and after ten years it’s still going strong!Note: I use it along with a red 12V LED automotive strip light to illuminate the tripod’s accessory tray. I bought the LED’s and the switched Battery Holder right here on Amazon.RayB

  22. Hard to rate but since purchase no issues

  23. It can suffer canada winter

  24. Works great and a good value lithium battery for my smoke detecters

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

  26. Best batteries for smoke alarm.

  27. Bought these to put in an old school smoke detector, since all the new detectors come with lithium batters pre-installed, and I haven’t heard it chirp yet for replacement.

  28. Great long lasting

  29. 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!!!

  30. Simple to use and longevity of battery!

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

  32. 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!

  33. Just as good as the top brands.

  34. works well

  35. Thought Lithium and Rechargeable were synonymous

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

  37. Door locks. Good service and price. Thanks

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

  39. 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.

  40. 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.

  42. Work great and a good vaule.
