Energizer CR2 Lithium Battery, Pack of 2

Excellent replacement for my smoke detectors.

De lo mejor de la marca. las que me llegaron se fabricaron en Dic. del 2023 asi que estan dando su mejor desempeño. Muy recomendables.

WOW! Amazing price and super fast delivery / Prime. I tend to be a Safety & Security nerd. If ever an emergency (smoke/fire/CO, etc.) seconds count to evacuate family/ pets. I legit have 4+ smoke detectors on each level of my house aside from other devices. I always have extra replacement batteries on hand for all my devices. After using my last reserve for a specific type of smoke detector I went to some of my local big stores and this exact battery was not carried, out of stock or highly overpriced. >> Thank you Amazon and this vendor / make... Instock, great price ( I really saved) and actually delivered within 24 hours. Awesome make, shelf time 10 years and very long lasting with consistent power. Highly recommended for immediate use per device specs and to keep in hand as backups (I have several devices that use these). *Too often people remove a battery and forget to replace I.e. smoke detector. Having extras means you can remove and replace immediately. Purchase extras 😀

CR2 batteries have been resigned and may not work in older devices. These batteries are great

Excelente calidad, duración y precio. Llegó antes de la fecha. Todo Ok
