  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. 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.

  3. 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.

  4. Batteries are made pretty much the same by each manufacturer. In sprite of what a little bunny may have told you, the brand is nowhere near as important as the type. and materials. With the long shelf life, these are especially great in test equipment that sits longer than is actually used. Any nine volt product will do better with these.

  5. 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!

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

  7. I needed a 9 volt Lithium battery to weather Michigan cold. I had tried standard batteries, but they didn’t last the winter. I bought the “Amazon Basics 4-Pack 9 Volt High-Performance Lithium Batteries” which were more reasonably priced than other brands. I use them in a remote motion sensor that sounds an alarm whenever a car enters my long driveway.

  8. Pour avertisseur de fumee.

  9. 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.

  10. These 9v batteries by Amazon Basics seem to be of good quality at a reasonable price. They are slightly smaller than competing Batteries, so the fit better in your devices.

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

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

  13. good price

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

  15. No me sirvió

  16. 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!

  17. 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

  18. I’m not an expert here, but I think the voltage on these is confusing my smoke detectors. The idea of replacing them less often was top on the list, but after replacing one it didn’t like it. Okay for a while, then beep, beep. The battery is still fully charged, but because it’s not the same top voltage as lithium the smoke detector thinks the battery is low.

  19. Replaced smoke detector original batteries.

  20. Unlike the alkaline batteries that had me up on a ladder every other month, these last six months or more between battery changes. What a pain to climb the ladder, remove the motion sensor from its mount, climb down the ladder, unscrew the battery cover and replace the battery. Once every six months is better than three times every six months. Less batteries used equals less money spent even if the lithium ion batteries are a bit more. The Amazon Basics brand helps take the bite out of the higher cost of lithium ion batteries. Happy with my purchase and will/have purchase(d) again.

  21. Loved the batteries. Worked as intended.

  22. Works well

  23. We learned that replacing 9 volt batteries can be a real chore. It can be so easy to accidentally pull off one of the wires from the attachment. Especially in smoke detectors, garage door opener remotes, etc., etc. This battery will extend the time that you have to do the replacement chore by at least 4 times in our experience. Thanks

  24. It’s in a nice cardboard box great for storage, but the plastic wrap is not required. It’s difficult to review a 10 year lithium battery. I use them for Smoke Detectors so I will update this review in 10 years. 🙂

  25. Work as well as the ones you pay a lot for. Pay less and shipping was fast.

  26. 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.

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

  28. Simple to use and longevity of battery!

  29. 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!

  30. Long lasting

  31. 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 !

  32. Door locks. Good service and price. Thanks

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

  34. So far they are perfect.

  35. Quality product. Prompt delivery.

  36. 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.

  37. great long lasting batteries

  38. Long life reduces battery changing

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

  40. All energizer batteries that I’ve had have always outlasted every other brand. Hands down…..the best. I’ve tried generics, scAmazon brand, Duracell…….only 1/2 the life of Energizer.

  41. Exactly what I needed, works as advertised.

  42. Last as long as advertised

  43. Energizer won’t let you down ! The bunny says it all!!! In all of our smoke detectors !
