1/2AA Size 3.6 Volt LS 14250 1200 mAh Lithium Battery ER14250 Non-Rechargeable 4 Pack Battery Compatible for Dog Collar Meter Sensor Movement Monitor/Home Security System/Alarm System

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.

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 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.

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.

Why did you pick this product vs others?: Qty and top of the list

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.

Item arrived well packaged and worked great. The batteries had a use by date several years into the future and powered the device I needed them for 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.

Fonctionne parfaitement avec mes équipements domotiques Aeotec Door Window Sensor 7

ちゃんと使えました。液漏れなど無いし、満足です。

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.
