EEMB 20-Pack ER14250 1/2AA 3.6V Lithium Battery - Non-Rechargeable, Long-Life for Home Automation, Alarms, & More

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.

Gets the job done!

I would give these replacement batteries zero stars if I could. Bought them six months ago to have a spare set. Went to use two of them today, and they are dead. Tried the other two, they are also dead. Garbage. Too late to return now so they’re going in the recycle bin. Waste of money.

Works good

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

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.

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.

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.

To quick to tell, but nice quick delivery thx

Como usuario habitual de sensores inalámbricos, puedo decir que estas baterías ER14250 de 3.6V (tecnología de litio cloruro de tionilo) ofrecen un rendimiento excelente. Son ideales para dispositivos de bajo consumo y larga duración como sensores de puertas, alarmas, contadores, medidores o sistemas IoT. Destaco tres cosas: 1. Tensión constante: mantienen voltaje estable hasta casi el final de su vida útil. No hay caídas de rendimiento bruscas. 2. Larga duración real: en condiciones normales pueden durar de 1 a 5 años, dependiendo del consumo del dispositivo. 3. Calidad del encapsulado: buen sellado, sin fugas, y soportan rangos amplios de temperatura, lo cual es clave en exteriores o ambientes exigentes. En mi caso, tras varias semanas de uso en un sensor de puerta, la lectura de voltaje sigue casi intacta y sin fallos de comunicación. Recomiendo especialmente si buscas fiabilidad en dispositivos que no puedes estar revisando cada dos por tres.

Great
