  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. Excellent batteries!

  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 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.

  5. 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.

  6. The batteries arrived very quickly. They were an exact match of the previous battery, which lasted ten years in the smoke alarm. Thank you!

  7. 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!

  8. Looking forward to a quality item!

  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. The package had been previously opened and poorly resealed. I should have returned it for a refund. I bought it for a remote control, used it for 2 weeks and now the so called 10-year battery does not function.

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

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

  14. good price

  15. the batteries didn’t have a far enough expiration date.. not powerful enough for a safe lock

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

  17. 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!

  18. 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

  19. Replaced smoke detector original batteries.

  20. I was originally shopping for 9 V lithium batteries, believing they would last longer than alkalines, especially in smoke detectors. However, reviews for lithium‘s were no better, they lasted no longer than alkalines. I ended up buying alkalines because I know how they perform, and Energizer is a great brand. Very happy with this purchase. Of course, only time will tell how long they last, but they perform beautifully.

  21. Didn’t seem to fit in my smoke detector. Discovered the battery has such square corners, it was catching on the detector’s plastic tab that doesn’t allow you to close the battery tray without a battery installed. Normal batteries are slightly rounded so they will push the tab down rather than catch on it. Fortunately there is room to help the tab retract on the back side of the open drawer so you can fully insert the lithium battery thereby depressing the plastic tab fully so the battery fits and the tray closes. I’m looking forward to many years with no beeping from weak batteries. Didn’t rate longevity or battery life as these are newly installed.

  22. Loved the batteries. Worked as intended.

  23. Works well

  24. only received one battery when 4 were advertised . ripoff

  25. I originally bought this product four years ago. I have 6 smoke detectors. One of the batteries went bad. Checking the other batteries they were all good.

  26. Very good in cold weather.

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

  28. Doesn’t fit in smoke detector! It’s slightly larger than the 9v alkaline batteries I had in my smoke detector previously. Very disappointed!!!!!

  29. I use a 9V battery in my garage door keypad. I do not use the keypad often so I need a battery that can last many years through all outdoor weather (hot and cold). These are more expensive than regular alkaline 9V batteries but over time the cost pays off with longevity.

  30. Simple to use and longevity of battery!

  31. Long lasting

  32. 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 !

  33. works well

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

  35. Door locks. Good service and price. Thanks

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

  37. So far they are perfect.

  38. 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.

  39. great long lasting batteries

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