No shelf life
These batteries have no shelf life so don’t count on them in an emergency. I bought two packs (8) total last November 2024 and they are all dead ☠️ dead ☠️ in September 2025.

Last a long time and a great price
I use these batteries for my garage door tender. Let’s me know when my garage door is open. The batteries last a long time. Last time I changed these batteries was 2 years ago.

Unusable batteries
These batteries are stored improperly or are terribly aged. Upon insertion into sensors for a security system or other device, the voltage dropped to 1.17Volts vs the required 3.65Volts. Buyer beware. No effort is made to maintain the stock under temperature control. Nor is there any assurance that these items shall deliver a minimum of 3.6Volts. Thus they are incapable of delivering anything close to the operating voltage, never mind the buyer’s expectation of getting 8 years of use. They are unusable as supplied.

Works in our oxygen monitor
These batteries were purchased to replace the dead battery and her old oxygen monitor. They are the correct size for our monitor and they look like they’re going tobe pretty good batteries. The battery four pack will probably last us a long time because this is the first time we’ve had to replace the batteries in years. Before purchasing these batteries, make sure your device uses this battery.

These fit my alarm sensor perfectly
I had purchased a different battery but same specs a year ago for this sensor. For some reason, when I placed them in I had to squeeze it in, it barely fit and did not make the low battery on the panel go away. After a delay in shipping and having to hear the constant low battery chirp for an extra day - these batteries were delivered and fit and worked perfectly - no squeezing.

Check the voltages
Had to update my review. Seller fixed this issue and made it right. Thank you. Waste of time. Two of the batteries only registered 1.5 volts.

Mucho más baratas que otra que compré de litio. Es para un aparatito especial y necesita estas pilas. La última me costó mucho más en una tienda y no ha durado ni un año. Veremos estas lo que duran. Pero por lo que me cobraron por 1, tengo 4. Si duran la mitad, todavía salgo ganando.
